Abstract
Fungal musculoskeletal infections often have subacute or indolent manifestations, making it difficult to distinguish them from other diseases and infections, given that they are relatively uncommon. Fungal infections occur by hematogenous spread, direct inoculation, or contiguous extension and may be related to different risk factors, including immunosuppression and occupational activity. The infection can manifest in isolation in the musculoskeletal system or as part of a systemic process. The fungi may be endemic to certain regions or may be found throughout the world, and this can help to narrow the diagnosis of the etiologic agent. Infections such as candidiasis, cryptococcosis, aspergillosis, and mucormycosis are often related to immunosuppression. On the other hand, histoplasmosis, paracoccidioidomycosis, coccidioidomycosis, and blastomycosis can occur in healthy patients in geographic areas where these infections are endemic. Furthermore, infections can be classified on the basis of the site of infection in the body. Some subcutaneous infections that can have osteoarticular involvement include mycetoma, sporotrichosis, and phaeohyphomycosis. Different fungi affect specific bones and joints with greater prevalence. Imaging has a critical role in the evaluation of these diseases. Imaging findings include nonspecific features such as osteomyelitis and arthritis, with bone destruction, osseous erosion, mixed lytic and sclerotic lesions, and joint space narrowing. Multifocal osteomyelitis and chronic arthritis with joint effusion and synovial thickening may also occur. Although imaging findings are often nonspecific, some fungal infections may show findings that aid in narrowing the differential diagnosis, especially when they are associated with the patient's clinical condition and history, the site of osteoarticular involvement, and the geographic location. ©RSNA, 2024.

Abstract
A 26-year-old woman presented an eyelid lesion, after being scratched by a cat that had a similar skin lesion. It evolved into a cervical lymph node enlargement. With a hypothesis of Parinaud´s oculoglandular syndrome (POS) due to cat scratch disease (CSD), doxycycline was prescribed. After two weeks of treatment without improvement, a biopsy and blood sample were obtained. Itraconazole was prescribed and the skin lesion improved, but not the lymph node enlargement. A Sporothrix schenckii complex was isolated from the skin sample. Also, a specie-specific polymerase chain reaction detected Bartonella henselae DNA in her blood sample. Azithromycin was included to treat the bacterial infection, whereupon the lymph node also receded successfully. Sporotrichosis and CSD are zoonoses that can be transmitted to humans by traumatic inoculation due to scratches or bites from cats. Both can evolve with POS. Patients who present skin lesions and/or POS after being wounded by a cat should be investigated for both diseases.

Rapid Molecular Diagnosis of Sporotrichosis Directly from Biological Samples from a Reference Center in Brazil. J Fungi (Basel) 2024; 10:432. [PMID: 38921418 PMCID: PMC11204681 DOI: 10.3390/jof10060432] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2024] [Revised: 06/13/2024] [Accepted: 06/14/2024] [Indexed: 06/27/2024] Open
Abstract
The gold standard diagnosis of sporotrichosis is the isolation of Sporothrix sp. in culture media, but this is a time-consuming test that is susceptible to contamination and can be affected by the fungal load. Molecular methods such as nested PCR are gaining more ground in the management of several infections as they are tools for the rapid and accurate identification of microorganisms from pure cultures or directly from biological samples. This study aimed to apply a nested PCR molecular protocol for the rapid detection of Sporothrix spp. directly from clinical samples. Thirteen samples-six from skin biopsies, five from skin exudates, and two from conjunctival secretions-were obtained from patients diagnosed with sporotrichosis due to S. brasiliensis. Calmodulin gene sequencing identified all the isolates as S. brasiliensis. Nested PCR was able to detect all the Sporothrix sensu lato directly from clinical samples as well as the CBS 120339 reference strain. The nested PCR protocol stands out as a diagnostic alternative, as it allows the identification of Sporothrix spp. directly from clinical samples without the need for fungal isolation.

Abstract
Sporotrichosis is a globally distributed subcutaneous mycosis caused by dimorphic Sporothrix species commonly found in soil, mosses, and decaying plant matter. The lymphocutaneous manifestation, historically associated with occupational activities and sapronotic transmission, has recently been observed to also occur through animal contact, particularly notable in Brazil. We describe a rare case of lymphocutaneous sporotrichosis with simultaneous pulmonary complications resulting from the scratching of a southern three-banded armadillo, Tolypeutes matacus, primarily inhabiting the arid forests of South America's central region. Speciation using multiplex quantitative polymerase chain reaction (qPCR) established the etiological agent as S. schenckii s. str., while amplified fragment length polymorphism (AFLP) analysis unveiled a novel genotype circulating in the Midwest of Brazil. The patient received treatment with itraconazole (200 mg/day) for two months, leading to substantial clinical improvement of cutaneous and pulmonary symptoms. This case highlights the critical role of animal-mediated transmission in sporotrichosis epidemiology, particularly within regions with diverse armadillo species. The unusual epidemiology and genetic characteristics of this case emphasize the need for enhanced awareness and diagnostic vigilance in atypical sporotrichosis presentations.

Abstract
Sporotrichosis is a traumatic mycosis affecting the skin or subcutaneous tissues caused by Sporothrix dimorphic fungus. The fungal complex includes several pathogenic species, out of which S. brasiliensis and S. schenckii are predominant in Brazil. In Mato Grosso do Sul (MS) state, the first human and animal cases were reported in 2016 in Corumbá and Ladário cities. Accordingly, we present the first occurrences of feline sporotrichosis detected in the state capital Campo Grande, MS, by the Zoonoses Control Service (ZCS) of the Municipal Public Health Department. The study included four allochthonous cases of feline sporotrichosis originating from Corumbá, MS, attended by the ZCS. All four cats presented classical clinical signs of sporotrichosis, as ulcerative nodular cutaneous lesions. Three slides tested positive by direct microscopy and PCR, followed by Sanger sequencing confirmed Sporothrix brasiliensis in two samples. The initial suspicion and diagnosis of feline sporotrichosis at the ZCS highlights the importance of accurate surveillance of sporotrichosis in non-endemic areas to enhance the capacity to prevent, detect and respond to emerging diseases in Campo Grande.

Abstract
Introduction Sporotrichosis is a subcutaneous mycosis caused by fungi of the genus Sporothrix sp. Phenotypic and genotypic differences have been associated with their geographic distribution, virulence, or clinical manifestation of sporotrichosis. In the past decade, the interest in identifying species of the Sporothrix sp. has been increasing, due to its epidemiological importance and, in consequence, is important to know how to preserve them for future studies, in culture collection. Aims The purposes of this study were to analyze the global distribution of environmental isolates and/or causal agents of sporotrichosis identified by polyphasic taxonomy, with mandatory use of molecular identification, and to evaluate the percentages and distribution of isolates stored in culture collections. Methods A systematic review of articles on animal and human sporotrichosis and/or environmental isolation of the fungus, from 2007 to 2023, was done. Results: Our results demonstrated that, S. globosa, S. schenckii, and S. brasiliensis were the most identified species. With respect to the deposit and maintenance of species, we observed that only 17% of the strains of Sporothrix sp. isolated in the world are preserved in a culture collection. Conclusions This systematic review confirmed a difficulty in obtaining the frequency of Sporothrix species stored in culture collection and insufficient data on the molecular identification mainly of animal sporotrichosis and isolation of Sporothrix sp. in environmental samples.

Silencing of Sporothrix schenckii GP70 Reveals Its Contribution to Fungal Adhesion, Virulence, and the Host-Fungus Interaction. J Fungi (Basel) 2024; 10:302.

Abstract
Sporothrix schenckii is one of the etiological agents of sporotrichosis, a cutaneous and subcutaneous infection distributed worldwide. Like other medically relevant fungi, its cell wall is a molecular scaffold to display virulence factors, such as protective pigments, hydrolytic enzymes, and adhesins. Cell wall proteins with adhesive properties have been previously reported, but only a handful of them have been identified and characterized. One of them is Gp70, an abundant cell wall protein mainly found on the surface of yeast-like cells. Since the protein also has a role in the activity of 3-carboxy-cis,cis-muconate cyclase and its abundance is low in highly virulent strains, its role in the Sporothrix-host interaction remains unclear. Here, a set of GP70-silenced strains was generated, and the molecular and phenotypical characterization was performed. The results showed that mutants with high silencing levels showed a significant reduction in the adhesion to laminin and fibrinogen, enzyme activity, and defects in the cell wall composition, which included reduced mannose, rhamnose, and protein content, accompanied by an increment in β-1,3-glucans levels. The cell wall N-linked glycan content was significantly reduced. These strains induced poor TNFα and IL-6 levels when interacting with human peripheral blood mononuclear cells in a dectin-1-, TLR2-, and TLR4-dependent stimulation. The IL-1β and IL-10 levels were significantly higher and were stimulated via dectin-1. Phagocytosis and stimulation of neutrophil extracellular traps by human granulocytes were increased in highly GP70-silenced strains. Furthermore, these mutants showed virulence attenuation in the invertebrate model Galleria mellonella. Our results demonstrate that Gp70 is a versatile protein with adhesin properties, is responsible for the activity of 3-carboxy-cis,cis-muconate cyclase, and is relevant for the S. schenckii-host interaction.

Abstract
OBJECTIVE This study aims to assess the clinical characteristics of sporotrichosis in low-endemic areas of China, including the prevalence geography, genotypic traits of patients, clinical manifestations, and strain virulence and drug sensitivities. The objective is to improve the currently used clinical management strategies for sporotrichosis. METHODS Retrospective data were collected from patients diagnosed with sporotrichosis through fungal culture identification. The isolates from purified cultures underwent identification using CAL (Calmodulin) gene sequencing. Virulence of each strain was assessed using a Galleria mellonella (G. mellonella) larvae infection model. In vitro susceptibility testing against commonly used clinical antifungal agents for sporotrichosis was conducted following CLSI criteria. RESULTS In our low-endemic region for sporotrichosis, the majority of cases (23) were observed in middle-aged and elderly women with a history of trauma, with a higher incidence during winter and spring. All clinical isolates were identified as Sporothrix globosa (S. globosa). The G. mellonella larvae infection model indicated independent and dose-dependent virulence among strains, with varying toxicity levels demonstrated by the degree of melanization of the G. mellonella. Surprisingly, lymphocutaneous types caused by S. globosa exhibited lower in vitro virulence but were more common in affected skin. In addition, all S.globosa strains displayed high resistances to fluconazole, while remaining highly susceptible to terbinafine, itraconazole and amphotericin B. CONCLUSION Given the predominance of elderly women engaged in agricultural labour in our region, which is a low-epidemic areas, they should be considered as crucial targets for sporotrichosis monitoring. S. globosa appears to be the sole causative agent locally. However, varying degrees of melanization in larvae were observed among these isolates, indicating a divergence in their virulence. Itraconazole, terbinafine and amphotericin B remain viable first-line antifungal options for treating S.globosa infection.

Abstract
The fingertip is the interface between humans and the world, including the various thorns, dirty needles, and other hazards to be found there. It is unsurprising that this is the site where hand infections most frequently occur. Although commonly encountered by hand surgeons and other physicians, fingertip infections have several mimics, and diagnosis and management is not always straightforward. Early diagnosis and treatment are key to success. As with all infections, they are more common and are more aggressive in immunosuppressed patients. This article reviews fingertip anatomy, common and uncommon fingertip infections and their mimics, and recommendations for management.

Abstract
Sporotrichosis is an implantation mycosis due to the genus Sporothrix. Cutaneous disseminated sporotrichosis is an unusual clinical form that often affects immunocompromised patients. We report a case of cutaneous disseminated sporotrichosis in an immunocompetent famer from a rural region of Madagascar, treated successfully with Itraconazole 200mg twice a day. This case highlights the role of multiple inoculation affecting different parts of the body as a risk factor of cutaneous disseminated sporotrichosis in an immunocompetent individually.

Abstract
Sporotrichosis is a rare type of fungal infection caused by Sporothrix fungus. Transmissions are commonly by traumatic inoculation of the fungus through the skin and subcutaneous tissue either from environmental exposure or contact with infected animals. Due to its mode of transmission, it is commonly affecting the upper limbs. Definitive diagnosis can be obtained by fungal culture test on secretion fluids, pus, bloods or tissue biopsy. We report a rare presentation of this disease appearing as a solitary chronic ulcer of the lip which was successfully treated with itraconazole.

Abstract
Sporotrichosis is a mycotic infection of the cutaneous and subcutaneous tissues caused by Sporothrix spp. that can also cause extracutaneous manifestations. This study aimed to characterize cutaneous and extracutaneous sporotrichosis lesions in cats. Over 1 year, 102 cats rescued by the Zoonoses Control Center of Belo Horizonte, Brazil, euthanized with clinical suspicion of feline sporotrichosis were evaluated. After euthanasia, the animals were evaluated by macroscopic, cytological, histopathological, and immunohistochemistry (IHC) examinations; fungal culture; and polymerase chain reaction (PCR). Sporothrix infection was identified by at least one diagnostic technique in all cats (n = 102) evaluated by postmortem examination, including 26/28 cases (93%) evaluated by IHC, 66/90 cases (73%) evaluated by cytology, 70/102 cases (68.6%) evaluated by histopathology, and 62/74 cases (84%) evaluated by fungal culture. Two cats had positive results only by fungal culture. Cytology and histopathology examinations were effective in diagnosing sporotrichosis, although IHC was needed to confirm the diagnosis in cats with low fungal loads. Sporothrix brasiliensis was confirmed by the sequencing of 3 samples. Skin lesions were characterized mainly by pyogranulomatous to granulomatous dermatitis (frequently with subcutaneous inflammation) with different intensities of Sporothrix spp. yeast. Extracutaneous findings associated with sporotrichosis included rhinitis or rhinosinusitis, lymphadenitis, pneumonia, meningitis, periorchitis, conjunctivitis, and glossitis. Extracutaneous infections were observed in 74/102 cases, and a possible association between the chronicity of the disease and the higher pathogenicity of this fungal species in cats requires further investigation.

Abstract
Sporotrichosis, the cutaneous mycosis most commonly reported in Latin America, is caused by the Sporothrix clinical clade species, including Sporothrix brasiliensis and Sporothrix schenckii sensu stricto. In Brazil, S. brasiliensis represents a vital health threat to humans and domestic animals due to its zoonotic transmission. Itraconazole, terbinafine, and amphotericin B are the most used antifungals for treating sporotrichosis. However, many strains of S. brasiliensis and S. schenckii have shown resistance to these agents, highlighting the importance of finding new therapeutic options. Here, we demonstrate that milteforan, a commercial veterinary product against dog leishmaniasis whose active principle is miltefosine, is a possible therapeutic alternative for the treatment of sporotrichosis, as observed by its fungicidal activity in vitro against different strains of S. brasiliensis and S. schenckii, and by its antifungal activity when used to treat infected epithelial cells and macrophages. Our results suggest milteforan as a possible alternative to treat feline sporotrichosis.

Abstract
Sporotrichosis, a fungal disease, is caused by exposure to soil that harbors Sporothrix schenckii or through inhalation of fungal spores. Skin is the most frequently exposed organ making sporotrichosis a primarily dermal disease. Many described reports in the literature suggest a connection of sporotrichosis with cutaneous squamous cell carcinoma with some connection between initial sporotrichosis diagnosis and treatment followed by development of cutaneous squamous cell carcinoma at the very site. Conversely, there is also evidence for sporotrichosis subsequent to skin cancer diagnosis, even after cancer chemotherapy, which points towards weakening of immune response by cancer chemotherapy leading to attack and infection by Sporothrix schenckii. We also propose and focus on inflammation as the connection between sporotrichosis, cancer and even the metastatic spread of cancer. Inflammation-associated IL-6, IFN-γ, natural killer cells and M2-macrophages possibly mechanistically link sporotrichosis with cancer, particularly cutaneous squamous cell carcinoma. These inflammation related factors/cells are regulated epigenetically raising the possibility of epigenetic regulation of sporotrichosis, which has not been described yet in the available literature. Clinical management of inflammation may thus be effective strategy not just against sporotrichosis but also the related onset of cutaneous squamous cell carcinoma and possibly its metastasis to lymph nodes.

Abstract
Approximately 70% (90.5 million) of United States (US) households own at least one pet. Dogs are the most common, making up about 38% of all household pets, followed by cats, which make up 25%. Other pets such as fish, birds, reptiles, and small animals such as hamsters, gerbils, and rabbits are less common household members. Pets are often considered a part of the family and there are significant medical and psychosocial benefits to pet ownership; however, the possibility of disease transmission exists related to the type of animal and infectious organism, and specific human risk factors. Immunocompromised individuals may be at increased risk of serious illness from zoonotic infections. During the transplant evaluation and routinely posttransplant, the multidisciplinary team should inquire about pet ownership and animal exposures to guide on potential risks. This review discusses the most common diseases seen in various household pets including dogs, cats, birds, fish, and some farm animals. We will also present guidelines for pet safety and include strategies to decrease the risk of infection while supporting the benefits of pet ownership after transplant.

Abstract
The dimorphic fungus Sporothrix schenckii is widely distributed in soil, vegetation, and decaying organic matter, and can cause sporotrichosis when the patient's skin trauma was exposed to contaminated material with Sporothrix spp. The cases of Sporothrix schenckii infection in chronic wounds are rarely reported. Here we reported a 53-year-old male construction worker who was admitted to our hospital on July 9, 2022, without underlying disease presented with a painless subcutaneous hard nodule on his right calf, which later ulcerated and oozed, with an enlarged wound and no fever during the course of the disease. His procalcitonin, C-reactive protein, erythrocyte sedimentation rate increased, and necrotic histopathology suggested chronic granulomatous inflammation. Then his necrotic tissue and pus were sent for metagenomic next generation sequencing(mNGS), the result reported Sporothrix schenckii after 43 hours, which was consistent with the result of culture after 18 days. mNGS might be more useful and valuable in diseases such as sporotrichosis where it is difficult to see the yeast cells in the tissues.

[PMID: 37481377 PMCID: PMC10589486 DOI: 10.1016/j.abd.2022.09.015] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2022] [Revised: 08/14/2022] [Accepted: 09/05/2022] [Indexed: 07/24/2023] Open
Abstract
BACKGROUND The evaluation of American cutaneous leishmaniasis (CL) and sporotrichosis (SP) with dermoscopy may improve the diagnosis accuracy and clinical monitoring. OBJECTIVES To describe the dermoscopic findings and patterns of skin lesions of patients with CL and SP followed up at the Laboratory of Clinical Research and Surveillance in Leishmaniasis (LaPClinVigiLeish), Evandro Chagas National Institute of Infectious Diseases (INI), Oswaldo Cruz Foundation, Rio de Janeiro, Brazil. METHODS The authors included patients with a diagnosis of CL or SP, who attended at INI/ Fiocruz, between 2019‒2021. All patients had 3 dermoscopic examinations (DermLite DL4): before treatment (T0), during treatment (T1), and after healing (T2). Up to three lesions per patient were evaluated. RESULTS The authors studied 47 patients with CL (74 lesions), and 19 patients with SP (24 lesions). The authors described dermoscopic structures such as rosettes, white lines, white dots, brown focal structureless areas, brown lines and dots, white perilesional circles, perilesional hyperchromic circles, microulcerations and the rainbow patterns. The authors created specific patterns; in CL: CL-T0 "central yellow scales with a white perilesional circle pattern", CL-T1 "diffuse structureless white area pattern" and CL-T2 "white and brown focal structureless areas pattern". In SP: SP-T0 the "pustule with erythema pattern"; SP-T1 the "focal structureless white areas with erythema pattern" and SP-T2 the "white linear pattern". STUDY LIMITATIONS This study does not correlate dermoscopic findings with time of disease evolution at the first medical examination. CONCLUSIONS The recognition of CL and SP dermoscopy patterns may be helpful tool for the differential diagnosis and monitoring of disease evolution.

Abstract
Background: Sporothrix brasiliensis causes sporotrichosis, an important infection in some groups of patients. Aims: This work was designed to investigate the effects of isavuconazole against this species. Methods: An antifungal susceptibility test was performed to compare MIC values with other antifungal drugs used to treat sporotrichosis. A checkerboard assay was performed to understand isavuconazole interactions. Furthermore, isavuconazole growth inhibition on an itraconazole-resistant strain was tested. Results: Isavuconazole had similar MICs to other azoles against S. brasiliensis, presenting fungistatic activity. Isavuconazole did not interact in vitro with antifungals or immunosuppressive drugs and inhibited the growth of an itraconazole-resistant strain. Conclusion: Isavuconazole inhibits S. brasiliensis, its pharmacologic characteristics make it a candidate for patients with sporotrichosis and it may be useful to combat sporotrichosis caused by resistant isolates.

Abstract
OBJECTIVES To describe the most common ocular lesions and demonstrate the frequency of ophthalmic involvement in a group of cats with systemic sporotrichosis. ANIMALS STUDIED Two hundred seventy-four cats diagnosed with systemic sporotrichosis. The inclusion criteria included previous positive cytopathological examination, histopathological examination, or fungal culture. PROCEDURES In a prospective case-control study, 274 cats diagnosed with systemic sporotrichosis underwent ophthalmic evaluation and received treatment for systemic sporotrichosis. Of these animals, 63 had ocular abnormalities which were recorded, and conjunctivitis was scored from 0 to 5. Diagnostic techniques utilized included fungal culture, as well as cytopathological (10 eyes; 10 cats), and histopathological examination of the palpebral conjunctiva and eyes (2 eyes). RESULTS Cytopathological and histopathological examination of the conjunctiva, as well as fungal culture, proved to be important tests for the detection of Sporothrix sp. Five cats without the evidence of ophthalmic abnormalities also had a positive fungal culture. The identified ocular lesions in animals with systemic sporotrichosis included increased serous discharge (79 eyes; 53 cats), blepharoconjunctivitis (33 eyes; 25 cats), conjunctivitis (39 eyes, 20 cats), blepharitis (9 eyes; 8 cats), uveitis (5 eyes; 3 cats), and Florida keratopathy-like lesions (2 eyes; 1 cat). CONCLUSION Sporotrichosis should be considered a differential diagnosis for conjunctivitis and blepharoconjunctivitis, especially in endemic areas. Fungal culture and cytopathology of ocular discharge and histopathological examinations of the conjunctiva are important for the diagnosis of ophthalmic sporotrichosis, although not all cats underwent laboratory testing in this study. Ocular discharge could be a source of contagion transmission.

Abstract
Sporotrichosis is a cutaneous mycosis that affects humans and animals and has a worldwide distribution. This infection is mainly caused by Sporothrix schenckii, Sporothrix brasiliensis, and Sporothrix globosa. Current research about anti-Sporothrix immunity has been mainly focused on S. schenckii and S. brasiliensis, using different types of human or animal immune cells. Granulocytes are a group of cells relevant for cytokine production, with the capacity for phagocytosis and the generation of neutrophil extracellular traps (NETs). Considering their importance, this study aimed to compare the capacity of human granulocytes to stimulate cytokines, uptake, and form NETs when interacting with different Sporothrix species. We found that conidia, germlings, and yeast-like cells from S. schenckii, S. brasiliensis, and S. globosa play an important role in the interaction with these immune cells, establishing morphology- and species-specific cytokine profiles. S. brasil-iensis tended to stimulate an anti-inflammatory cytokine profile, whilst the other two species had a proinflammatory one. S. globosa cells were the most phagocytosed cells, which occurred through a dectin-1-dependent mechanism, while the uptake of S. brasiliensis mainly occurred via TLR4 and CR3. Cell wall N-linked and O-linked glycans, along with β-1,3-glucan, played a significant role in the interaction of these Sporothrix species with human granulocytes. Finally, this study indicates that conidia and yeast-like cells are capable of inducing NETs, with the latter being a better stimulant. To the best of our knowledge, this is the first study that reports the cytokine profiles produced by human granulocytes interacting with Sporothrix cells.

Abstract
Sporotrichosis is a subcutaneous mycosis caused by a dimorphic fungus belonging to the genus Sporothrix. This fungal infection can affect both humans and domestic animals, and in recent years, an increase in the geographic spread and prevalence of sporotrichosis has been observed globally. This systematic review aimed to examine the clinical-epidemiological and therapeutic aspects related to sporotrichosis co-infection with human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS). An extensive electronic search was conducted on databases including PubMed, Web of Science, Lilacs, Medline, Embase, Scopus and SciELO was performed to identify clinical cases of people living with HIV (PLWH) with sporotrichosis published until May 2023. As a result, we found that most co-infected patients were male, representing 71.76% (94/131) of cases. The most prevalent age group was 41-50 years, with a mean age of 36.98 years. The countries with the highest number of cases were Brazil (75.57%, 99/131) and the United States (16.03%, 21/131). The most frequent clinical presentation was systemic dissemination, accounting for 69.47% (91/131) of the cases, followed by cutaneous dissemination with 13% (17/131). The mean CD4+ cell count was 154.07 cells/μL, and most patients used amphotericin B with at least one azole, which represented 47.33% (62/131) of cases, followed by azole monotherapy in 17.56% (23/131) of cases. As for the outcome, 51.15% (67/131) of the patients remained alive, and 37.4% (49/131) died. Therefore, it was concluded that sporotrichosis in PLWH is a disease with a high prevalence in Brazil and may be associated with systemic clinical manifestations requiring longer periods of systemic antifungal therapy.

Abstract
RNA-binding proteins (RBPs) are essential for regulating RNA metabolism, stability, and translation within cells. Recent studies have shown that RBPs are not restricted to intracellular functions and can be found in extracellular vesicles (EVs) in different mammalian cells. EVs released by fungi contain a variety of proteins involved in RNA metabolism. These include RNA helicases, which play essential roles in RNA synthesis, folding, and degradation. Aminoacyl-tRNA synthetases, responsible for acetylating tRNA molecules, are also enriched in EVs, suggesting a possible link between these enzymes and tRNA fragments detected in EVs. Proteins with canonical RNA-binding domains interact with proteins and RNA, such as the RNA Recognition Motif (RRM), Zinc finger, and hnRNP K-homology (KH) domains. Polyadenylate-binding protein (PABP) plays a critical role in the regulation of gene expression by binding the poly(A) tail of messenger RNA (mRNA) and facilitating its translation, stability, and localization, making it a key factor in post-transcriptional control of gene expression. The presence of proteins related to the RNA life cycle in EVs from different fungal species suggests a conserved mechanism of EV cargo packing. Various models have been proposed for selecting RNA molecules for release into EVs. Still, the actual loading processes are unknown, and further molecular characterization of these proteins may provide insight into the mechanism of RNA sorting into EVs. This work reviews the current knowledge of RBPs and proteins related to RNA metabolism in EVs derived from distinct fungi species, and presents an analysis of proteomic datasets through GO term and orthology analysis, Our investigation identified orthologous proteins in fungal EVs on different fungal species.

Abstract
BACKGROUND Cutaneous disseminated sporotrichosis (CDS), also called hematogenous sporotrichosis, is a rare condition that usually affects immunocompromised patients. The current work presents the case of a woman with diabetes mellitus associated with CDS. CASE PRESENTATION A 59-year-old woman with diabetes mellitus presented with a two-year history of ulcerated rashes on the left ankle and both sides of the jaw. Physical examination revealed three annular areas of erythematous and raised plaque with an ulcer over the left ankle and both sides of the jaw. Based on laboratory findings, elevated blood glucose concentration and decreased white cell count were observed. Sporothrix globosa was identified in the mycological culture of biopsied tissue from the three lesions and this was confirmed by DNA sequencing. The skin lesions healed after two-month itraconazole therapy. CONCLUSIONS Diabetes is a risk factor for disseminated sporotrichosis, which may be induced by hematogeneous spread, repeated inoculation, or autoinoculation. This study raises awareness among clinicians, with regard to the notion that people with possibly altered immune function are potentially vulnerable to severe clinical forms of sporotrichosis.

Sporotrichosis in Older Adults: A Cohort Study of 911 Patients from a Hyperendemic Area of Zoonotic Transmission in Rio de Janeiro, Brazil. J Fungi (Basel) 2023; 9:804.

Abstract
Generally, older people tend to suffer from more severe infections than younger adults. In addition, there are accumulations of comorbidities and immune senescence in some cases. This cohort study evaluated the clinical and epidemiological characteristics of older adults (≥60 years old) with sporotrichosis. The cohort consisted of 911 patients with a median age of 67 years, most of whom were female (72.6%), white (62.1%), and afflicted with comorbidities (64.5%). The lymphocutaneous form occurred in 62% of the patients, followed by the fixed form (25.7%), cutaneous disseminated form (8.9%), and extracutaneous/disseminated forms (3.3%). In this study, we draw attention to the frequency of osteoarticular involvement (2.1%) secondary to skin lesions such as osteomyelitis and/or tenosynovitis. A clinical cure was achieved in 87.3% of cases. Itraconazole was used in 81.1% of cases, while terbinafine was used in 22.7% of cases, usually in low doses. Survival analysis showed that the median treatment time was 119 days, and the multiple Cox model demonstrated that the presentation of a black coloration and diabetes was associated with a longer treatment time required to establish a cure. Therefore, these subgroups should be monitored more closely to reduce possible difficulties during treatment. It would be interesting to conduct more studies analyzing older adults with sporotrichosis from different geographic areas to better comprehend the disease in this group.

Abstract
Proteomics provide a robust approach to profile and quantify proteins within cells, organs, or tissues, providing comprehensive insights about the dynamics of cellular processes, modifications, and interactions. Similarly, understanding the transcriptome is essential to decipher functional elements of the genome, unraveling the mechanisms of disease development and the molecular constituents of cells and tissues. Some thermodimorphic fungi of the genus Sporothrix cause sporotrichosis, a subcutaneous mycosis of worldwide relevance. The transcriptome and proteome of the main Sporothrix species of clinical interest can elucidate the mechanisms underlying pathogenesis and host interactions. Studies of these techniques can contribute to the advancement of novel diagnostic and therapeutic strategies. A literature review was carried out, addressing all articles based on proteomics using mass spectrometry and transcriptomics of Sporothrix spp. Twenty-one studies were eligible for this review. The main findings include proteins and genes involved in dimorphism, cell differentiation, thermotolerance, virulence, immune evasion, metabolism, cell adhesion, cell transport, and biosynthesis. With the spread and emergence of sporotrichosis in different countries, ongoing research efforts and new discoveries are welcome to advance knowledge about this mycosis and its agents.

Abstract
Zoonotic outbreaks of sporotrichosis are increasing in Brazil. We examined and described the emergence of cat-transmitted sporotrichosis (CTS) caused by the fungal pathogen Sporothrix brasiliensis. We calculated incidence and mapped geographic distribution of cases in Curitiba, Brazil, by reviewing medical records from 216 sporotrichosis cases diagnosed during 2011-May 2022. Proven sporotrichosis was established in 84 (39%) patients and probable sporotrichosis in 132 (61%). Incidence increased from 0.3 cases/100,000 outpatient visit-years in 2011 to 21.4 cases/100,000 outpatient visit-years in 2021; of the 216 cases, 58% (n = 126) were diagnosed during 2019-2021. The main clinical form of sporotrichosis was lymphocutaneous (63%), followed by localized cutaneous (24%), ocular (10%), multisite infections (3%), and cutaneous disseminated (<0.5%). Since the first report of CTS in Curitiba in 2011, sporotrichosis has increased substantially, indicating continuous disease transmission. Clinician and public awareness of CTS and efforts to prevent transmission are needed.

Abstract
Fungal diseases are a leading threat to human health, especially in individuals with compromised immunity. Although there have been recent important advances in antifungal drug development, antifungal resistance, drug-drug interactions and difficulties in delivery remain major challenges. Among its pleiotropic actions, nitric oxide (NO) is a key molecule in host defense. We have developed a flexible nanoparticle platform that delivers sustained release of NO and have demonstrated the platform's efficacy against diverse bacteria as well as some fungal species. In this work, we investigate the effects of two NO-releasing particles against a panel of important human yeast. Our results demonstrate that the compounds are both effective against diverse yeast, including ascomycota and basidiomycota species, and that NO-releasing particles may be a potent addition to our armamentarium for the treatment of focal and disseminated mycoses.

Abstract
Diagnosis of superficial/cutaneous fungal infections from skin, hair and nail samples is generally achieved using microscopy and culture in a microbiology laboratory, however, any presentation that is unusual or subcutaneous is sampled by taking a biopsy. Using histological techniques a tissue biopsy enables a pathologist to perform a full examination of the skin structure, detect any inflammatory processes or the presence of an infectious agent or foreign body. Histopathological examination can give a presumptive diagnosis while a culture result is pending, and may provide valuable diagnostic information if culture fails. This review demonstrates how histopathology contributes to the diagnosis of fungal infections from the superficial to the life threatening.

Abstract
Sporotrichosis, an invasive fungal infection caused by Sporothrix schenckii, has emerged in Southeast Asia, affecting cats and posing a potential zoonotic risk to humans. We evaluated 38 feline sporotrichosis cases in and around Bangkok, Thailand, from 2017 to 2021. The isolates were phenotypically and genotypically characterized. The cats infected with sporotrichosis were mainly young adults, males, and domestic short hairs with uncontrolled outdoor access, and they lived in Bangkok. All isolates showed low thermotolerance and converted to the yeast phase at 35 °C. Based on the internal transcribed spacer region of rDNA sequences, our strains belonged to S. schenckii sensu stricto and clustered with clinical clade D. Based on the concatenated tree of calmodulin and beta-tubulin genes, five groups of S. schenckii were generated, and the monophyletic clade, Group II, of Thai strains was recognized. In vitro antifungal susceptibility testing demonstrated that the MIC50 of our isolates to amphotericin B, itraconazole, and posaconazole were within the limit of the species-specific epidemiological cutoff values, suggesting that the organisms were the wild type. Addressing the outbreak of feline sporotrichosis in Thailand by providing guidelines for diagnosis and effective treatment may help control the spread of disease and reduce the risk of cat-transmitted sporotrichosis to humans.

Abstract
INTRODUCTION Sporotrichosis is a subcutaneous and chronic infection caused by traumatic inoculation of pathogenic sporothrix species, usually infecting the skins and subcutaneous tissues of humans and animals. However, the lack of epidemiological data required further molecular identification to describe the distribution of this fungus in our region. In this study, forty-eight clinical sporothrix isolated from Sun Yat-Sen Memorial Hospital were classified, and the susceptibility of each strain to seven antifungal agents was determined. METHODS Forty strains of S. globosa and eight strains of S. shenkshii were identified via colony morphology and PCR sequencing of calmodulin gene. RESULTS Antifungal susceptibility tests of the mycelial phase in vitro showed terbinafine (TRB) and luliconazole (LULI) were the most effective, followed by itraconazole (ITZ) and amphotericin B (AMB). By contrast, voriconazole (VCZ), 5-flucytosine (5FC) and fluconazole (FCZ) have low efficacy with high MIC. CONCLUSION Our results showed a predominantly S. globosa infection trend in southern China. Simultaneously, sporothrix is sensitive to TRB, LULI, ITZ and AMB whereas resistant to FCZ. This study firstly reports antifungal sensitivity test in vitro and epidemiological correlation analysis of sporothrix in southern China, and also the first time to find that sporothrix is sensitive to LULI.

Abstract
Melanin, an important virulence factor of pathogenic fungi, has been shown to suppress host immune responses in multiple ways. Autophagy is a vital cellular mechanism underlying the host's innate immunity against microbial infections. However, the potential influence of melanin on autophagy has not been explored. We investigated the effect of melanin on autophagy in macrophages, which play a key role in controlling Sporothrix spp. infection, as well as the mechanism of melanin interaction with Toll-like receptor (TLR)-induced pathways. Sporothrix globosa conidia (wild-type and melanin-deficient mutant strains) or yeast cells were co-cultured with THP-1 macrophages to demonstrate that, although S. globosa infection led to the activation of autophagy-related proteins and increased autophagic flux, S. globosa melanin suppressed macrophage autophagy. Incubation with S. globosa conidia also increased the expression levels of reactive oxygen species and multiple proinflammatory cytokines (interleukin-6, tumor necrosis factor-α, interleukin-1β and interferon-γ) in macrophages. These effects were attenuated as melanin presented. Furthermore, while S. globosa conidia significantly increased the expression of both TLR2 and TLR4 in macrophages, the knockdown of TLR2, but not TLR4, with small interfering RNA suppressed autophagy. Overall, this study revealed the novel immune defense ability of S. globosa melanin to inhibit macrophage functionality by resisting macrophage autophagy through the regulation of TLR2 expression.

Abstract
Sporotrichosis is a human and animal fungal infection distributed worldwide that is caused by the thermodimorphic species of the Sporothrix pathogenic clade, which includes Sporothrix brasiliensis, Sporothrix schenckii, and Sporothrix globosa. The cell wall composition and the immune response against the Sporothrix species have been studied mainly in S. brasiliensis and S. schenckii, whilst little is known about the S. globosa cell wall and the immune response that its components trigger. Therefore, in this study, we aimed to analyze the cell wall composition of S. globosa in three morphologies (germlings, conidia, and yeast-like cells) and the differences in cytokine production when human peripheral blood mononuclear cells (PBMCs) interact with these morphotypes, using S. schenckii and S. brasiliensis as a comparison. We found that S. globosa conidia and yeast-like cells have a higher cell wall chitin content, while all three morphologies have a higher β-1,3-glucan content, which was found most exposed at the cell surface when compared to S. schenckii and S. brasiliensis. In addition, S. globosa has lower levels of mannose- and rhamnose-based glycoconjugates, as well as of N- and O-linked glycans, indicating that this fungal cell wall has species-specific proportions and organization of its components. When interacting with PBMCs, S. brasiliensis and S. globosa showed a similar cytokine stimulation profile, but with a higher stimulation of IL-10 by S. globosa. Additionally, when the inner cell wall components of S. globosa were exposed at the surface or N- and O-glycans were removed, the cytokine production profile of this species in its three morphotypes did not significantly change, contrasting with the S. schenckii and S. brasiliensis species that showed different cytokine profiles depending on the treatment applied to the walls. In addition, it was found that the anti-inflammatory response stimulated by S. globosa was dependent on the activation of dectin-1, mannose receptor, and TLR2, but not TLR4. All of these results indicate that the cell wall composition and structure of the three Sporothrix species in the three morphologies are different, affecting their interaction with human PBMCs and generating species-specific cytokine profiles.

Abstract
Background
Sporotrichosis is a subcutaneous or implantation mycosis caused by some species of the genus Sporothrix. Rio de Janeiro state, Brazil, experiences hyperendemic levels of zoonotic sporotrichosis, with increasing cases of disseminated disease, especially in people living with HIV (PLHIV). Involvement of the nasal mucosa is rare and occurs isolated or in disseminated cases, with a delayed resolution.
Methodology/Principal findings
This study aimed to describe the epidemiological, clinical, and therapeutic profiles of 37 cases of sporotrichosis with involvement of the nasal mucosa treated at the ear, nose, and throat (ENT) outpatient clinic of the Instituto Nacional de Infectologia Evandro Chagas, Fundação Oswaldo Cruz, from 1998 to 2020. Data were reviewed from the medical records and stored in a database. The Mann–Whitney test was used to compare the means of quantitative variables, and Pearson chi-square and Fisher’s exact tests were used to verify the association between qualitative variables (p<0.05). Most patients were males, students or retirees, with a median age of 38 years, residents in the municipality of Rio de Janeiro, and infected through zoonotic transmission. Disseminated sporotrichosis forms in patients with comorbidities (mostly PLHIV) were more common than the isolated involvement of the mucosa. The main characteristics of lesions in the nasal mucosa were the presence/elimination of crusts, involvement of various structures, mixed appearance, and severe intensity. Due to therapeutic difficulty, itraconazole was combined with amphotericin B and/or terbinafine in most cases. Of the 37 patients, 24 (64.9%) healed, with a median of 61 weeks of treatment, 9 lost follow-up, 2 were still treating and 2 died.
Conclusions
Immunosuppression was determinant to the outcome, with worse prognosis and lower probability of cure. Notably in this group, the systematization of the ENT examination for early identification of lesions is recommended to optimize the treatment and outcome of the disease.

Abstract
Background: Sporotrichosis is a fungal infection that can affect both humans and animals, caused by a species of thermo-dimorphic fungi of the genus Sporothrix. This pathology can be acquired by subcutaneous traumatic inoculation through contact with contaminated plants, soil or decomposing organic matter, and/or by inhalation of conidia. The infection can progress to chronic skin infection, or it can even spread to blood vessels, lymph, muscles, bones, and other organs, such as the lungs and nervous system. Those disseminated types are usually associated with cellular immunodeficiency and infection by inhalation, which explains why people living with human immunodeficiency virus (PLHIV) get infected in such a manner. This virus changes the natural history of sporotrichosis, producing a greater fungal load. Methods: The search was carried out in three databases: Pubmed, Scopus, and Scielo. Eligible articles were considered as those that described sporotrichosis in patients infected with HIV-AIDS, as well as case series. Results: A total of 24 articles were selected, with a sum of 37 patients with sporotrichosis and HIV infection. Of these patients, 31 came from Brazil, two from the United States, one from South Africa, one from Bangladesh, and two from an unspecified region. Regarding epidemiology, a predominance of the male sex was found in 28 of the 37 cases (75.6%), while nine were female (24.3%). Conclusions: Sporotrichosis infection continues to present in a more severe and disseminated way among HIV-positive subjects with lower CD4+ counts.

Abstract
An epidemic of cat-transmitted sporotrichosis caused by Sporothrix brasiliensis has emerged as a major public health threat in Brazil in recent decades. We report the first three cases of cat-transmitted sporotrichosis caused by Sporothrix brasiliensis outside South America, and the first ever cases of cat-transmitted sporotrichosis in the United Kingdom. We outline the public health implications and outbreak response and encourage clinicians and veterinarians worldwide to be vigilant for sporotrichosis in cats and cat owners.

Abstract
Graphilbum species are important blue stain fungi associated with pine trees and are widely distributed throughout Asia, Australia, and North Africa. Pine wood nematode (PWN) primarily feed on ophiostomatoid fungi such as Graphilbum sp. in wood, the population of PWNs was increased, and incomplete organelle structures were observed in Graphilbum sp. hyphal cells following exposure to PWNs. In this study, we showed that Rho and Ras were involved in the MAPK pathway, SNARE binding and small GTPase-mediated signal transduction, and their expression was upregulated in the treatment group. However, the expression of the Rab7 involved in MAPK and small GTPase-mediated signal pathway was downregulated in the treatment group. Thus, further research is needed to study the MAPK pathway and related Ras and Rho genes in Graphilbum sp. associated with the PWN population. Overall, transcriptomic analysis clarified the basic mechanisms of mycelial growth in Graphilbum sp. fungus used as a food source by PWNs.

Abstract
PURPOSE To describe 120 cases of ocular sporotrichosis. METHODS Review of medical records of patients with culture-proven (from eye specimen) ocular sporotrichosis, in Rio de Janeiro, from 2007 to 2017. RESULTS Women were more affected (61.7%) and median age was 24 years. The isolated ocular form was more frequent (75.8%). Fixed cutaneous sporotrichosis was the most commonly associated form (48.3%). Hypersensitivity reactions were observed in 10% of patients. Ocular involvement was unilateral in 98.3% of the cases, and the most frequent clinical presentation was granulomatous conjunctivitis (86.7%), followed by eyelid lesion (25%). Dacryocystitis represented 7.5% of the cases, predominantly in children (55.6%). Itraconazole was the first choice treatment (95.8%). Sequelae were observed in 23 patients (22.5%), and surgical treatment was required for most of them. CONCLUSION Ocular sporotrichosis can be considered a characteristic form of the zoonotic transmission, with high morbidity. Delay in initiating specific treatment is likely to increase the risk of progression to more severe forms of the disease, and development of ocular sequelae.

Abstract
Sporotrichosis is a rare form of subacute and chronic fungal infection in renal transplant recipients caused by the ubiquitous fungus Sporothrix schenckii. It is usually described in renal allograft recipients who have not been treated with antifungal prophylaxis. We report a rare case of cutaneous sporotrichosis in a 39-year-old renal allograft recipient already on antifungal prophylaxis, who presented with skin lesions. The diagnosis was made from a skin biopsy. The patient had increased tacrolimus levels after starting treatment with itraconazole, which was later changed to terbinafine and cryotherapy. The patient responded to treatment with regression of his lesions.

Abstract
Sporotrichosis is an uncommon subacute or chronic infection caused by Sporothrix spp. In some urban areas of Latin America, sporotrichosis has been considered an emergent cosmopolitan disease of zoonotic transmission by domestic cats. There are four different clinical forms of the disease: fixed cutaneous, lymphocutaneous, multifocal or disseminated cutaneous, and extracutaneous. The oral mucosa is rarely involved, usually as unspecified chronic ulcers in the context of multifocal or disseminated cutaneous form of systemic sporotrichosis. Microscopical features include chronic granulomatous inflammation containing microabscesses and fungal hyphae positive for Periodic acid Schiff and silver-based stains. The diagnosis of sporotrichosis is usually based on culture detection and strict correlation of clinical, microscopical and laboratorial data. We herein contribute with two additional illustrative cases of oral manifestation of sporotrichosis in immunocompromised patients from an endemic urban area from Rio de Janeiro-Brazil. Key words:Sporotrichosis, ulcer, oral cavity, immunosuppression.

Abstract
Lung diseases continue to draw considerable attention from biomedical and public health care agencies. The lung with the largest epithelial surface area is continuously exposed to the external environment during exchanging gas. Therefore, the chances of respiratory disorders and lung infections are overgrowing. This review has covered promising and opportunistic etiologic agents responsible for lung infections. These pathogens infect the lungs either directly or indirectly. However, it is difficult to intervene in lung diseases using available oral or parenteral antimicrobial formulations. Many pieces of research have been done in the last two decades to improve inhalable antimicrobial formulations. However, very few have been approved for human use. This review article discusses the approved inhalable antimicrobial agents (AMAs) and identifies why pulmonary delivery is explored. Additionally, the basic anatomy of the respiratory system linked with barriers to AMA delivery has been discussed here. This review opens several new scopes for researchers to work on pulmonary medicines for specific diseases and bring more respiratory medication to market.

Abstract
Osteoarticular mycoses are chronic debilitating infections that require extended courses of antifungal therapy and may warrant expert surgical intervention. As there has been no comprehensive review of these diseases, the International Consortium for Osteoarticular Mycoses prepared a definitive treatise for this important class of infections. Among the etiologies of osteoarticular mycoses are Candida spp., Aspergillus spp., Mucorales, dematiaceous fungi, non-Aspergillus hyaline molds, and endemic mycoses, including those caused by Histoplasma capsulatum, Blastomyces dermatitidis, and Coccidioides species. This review analyzes the history, epidemiology, pathogenesis, clinical manifestations, diagnostic approaches, inflammatory biomarkers, diagnostic imaging modalities, treatments, and outcomes of osteomyelitis and septic arthritis caused by these organisms. Candida osteomyelitis and Candida arthritis are associated with greater events of hematogenous dissemination than those of most other osteoarticular mycoses. Traumatic inoculation is more commonly associated with osteoarticular mycoses caused by Aspergillus and non-Aspergillus molds. Synovial fluid cultures are highly sensitive in the detection of Candida and Aspergillus arthritis. Relapsed infection, particularly in Candida arthritis, may develop in relation to an inadequate duration of therapy. Overall mortality reflects survival from disseminated infection and underlying host factors.

Abstract
Rhodotorula mucilaginosa, an environmental yeast widely used in industry and agriculture, is also an opportunistic pathogen resistant to multi-antifungals. During the national surveillance in China, R. mucilaginosa has been documented from various hospitals and regions. At present, the molecular epidemiology of invasive infections caused by R. mucilaginosa and their resistance profiles to antifungals were unknown. Here we collected 49 strains from four hospitals located in different geographic regions from 2009 to 2019 in China, determined their genotypes using different molecular markers and quantified susceptibilities to various antifungals. Sequencing of ITS and D1/D2 regions in rDNA indicated that 73.5% (36/49) of clinical strains belong to same sequence type (rDNA type 2). Microsatellite (MT) genotyping with 15 (recently developed) tandem repeat loci identified 5 epidemic MT types, which accounted for 44.9% (22/49) of clinical strains, as well as 27 sporadic MT types. Microsatellite data indicated that the presence of an epidemic cluster including 35 strains (71.4%) repeatedly isolated in four hospitals for eight years. Single nucleotide variants (SNVs) from the whole genome sequence data also supported the clustering of these epidemic strains due to low pairwise distance. In addition, phylogenetic analysis of SNVs from these clinical strains, together with environmental and animal strains showed that the closely related epidemic cluster strains may be opportunistic, zoonotic pathogens. Also, molecular data indicated a possible clonal transmission of pan echinocandins-azoles-5-flucytosine resistant R. mucilaginosa strains in hospital H01. Our study demonstrated that R. mucilaginosa is a multi-drug resistant pathogen with the ability to cause nosocomial infection.
