Abstract
Cryptococcosis is an infectious disease of worldwide distribution, caused by encapsulated yeasts belonging to the phylum Basidiomycota. The genus Cryptococcus includes several species distributed around the world. The C. gattii/neoformans species complex is largely responsible for most cases of cryptococcosis. However, clinical series have been published of infections caused by Papiliotrema (Cryptococcus) laurentii and Naganishia albida (Cryptococcus albidus), among other related genera. Here, we examined the pathogenic potential and antifungal susceptibility of C. gattii/neoformans species complex (clades I and II) and related genera (Papiliotrema and Naganishia) isolated from environmental and clinical samples. P. laurentii (clade III), N. liquefasciens/N. albidosimilis (clade IV); and N. adeliensis/N. albida (clade V) strains produced higher levels of phospholipase and hemolysins, whereas the C. gattii/neoformans species complex strains (clades I and II) had markedly thicker capsules, produced more biofilm biomass and melanin, which are known virulence attributes. Interestingly, 40% of C. neoformans strains (clade II) had MICs above the ECV established for this species to amphotericin B. Several non-C. gattii/neoformans species complex (clades III to V) had MICs equal to or above the ECVs established for C. deuterogattii and C. neoformans for all the three antifungal drugs tested. Finally, all the non-C. gattii/neoformans clinical isolates (clades III to V) produced more melanin than the environmental isolates might reflect their particularly enhanced need for melanin during in vivo protection. It is very clear that C. gattii/neoformans species complex (clades I and II) strains, in general, show more similar virulence phenotypes between each other when compared to non-C. gattii/neoformans species complex (clades III to V) isolates. These observations together with the fact that P. laurentii and Naganishia spp. (clades III to V) strains were collected from the outside of a University Hospital, identify features of these yeasts important for environmental and patient colonization and furthermore, define mechanisms for infections with these uncommon pathogens.

Matsui H, Higashide M, Hanaki H. Evaluation of a rapid immunochromatographic test for the detection of Candida species from oropharyngeal samples. J Microbiol Methods 2020; 179:106090. [PMID: 33129918 DOI: 10.1016/j.mimet.2020.106090] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/09/2020] [Revised: 10/26/2020] [Accepted: 10/26/2020] [Indexed: 01/04/2023]
Abstract
Oropharyngeal candidiasis is the most common opportunistic fungal infectious disease. Culture methods and microscopy are used to detect the presence of Candida species in clinical specimens. We have previously developed an immunochromatographic test (ICT) to enable the simple and rapid diagnosis of candidiasis. In this study, we evaluated the performance of the ICT for the detection of Candida species from pharyngeal swabs and compared the results with those of the culture method. The isolated Candida species were identified using polymerase chain reaction-restriction fragment length polymorphism, and viable cell counts were determined using selective chromogenic agar. The detection rate of C. albicans was 63.3% and 0% among ≤102 and ≥ 106 colony-forming units (CFU)/mL of viable Candida cells from pharyngeal swabs, respectively. The detection rate of nonC. albicans Candida species, especially C. glabrata, increased commensurately from 16.7% at ≤102 CFU/mL to 75.0% at ≥106 CFU/mL. Among the 300 pharyngeal swabs analyzed, 59 cultures detected Candida species at a count of >103 CFU/mL (53 were ICT-positive). Of the remaining 241 culture-negative specimens, 219 were ICT-negative. The sensitivity, specificity, and accuracy of the ICT were 89.8%, 90.9%, and 90.7%, respectively. Taken together, the ICT evaluated can be made readily available for clinical use in detecting Candida.

Abstract
Cryptococcus albidus, synonymous with Naganishia albida, rarely causes opportunistic infection in immunocompromised individuals. Its clinical features, particularly in children, are not well defined. Here, we report a case of C albidus fungemia in an immunosuppressed child; we also present results of a systematic review, for which we searched PubMed, Embase, and Web of Science using the keywords "cryptococcus" and "albidus." Our goal was to describe the spectrum of disease, diagnostic approaches, therapies, and outcomes. We identified 20 cases of invasive infection, only 2 of which involved children, and 7 cases of noninvasive infection. The reports originated in the Americas, Europe, and Asia. Of those with invasive infection, 16 (80%) patients had an underlying chronic disorder or had received immunosuppressive therapy, 8 (40%) had fungemia, and 6 (30%) had a central nervous system infection. The attributable case fatality rate was 40%. C albidus is an opportunistic yeast that can rarely cause life-threatening fungemia and central nervous system infection in individuals of any age, especially those who are immunocompromised.

Abstract
Bird fecal matter is considered a potential source of pathogenic microbes such as yeast species that contaminate the environment. Therefore, it needs to be scrutinized to assess potential environmental health risks. The aim of this study was to investigate the diversity of the yeasts in pigeon fecal droppings, their antifungal susceptibility patterns, and virulence factors. We used culturing techniques to detect the yeasts in pigeon fecal droppings. The isolates were then characterized based on colony morphologies, microscopic examinations, and biochemical reactions. The molecular identification of all yeast isolates was performed by sequencing of the amplified ITS gene. Genes encoding virulence factors CAP1, CAP59, and PLB were also detected. Antifungal susceptibility patterns were examined by the disk diffusion method. A total of 46 yeast-like isolates were recovered, and they belonged to nine different genera, namely, Cryptococcus, Saccharomyces, Rhodotorula, Candida, Meyerozyma, Cyberlindnera, Rhodosporidium, Millerozyma, and Lodderomyces. The prevalence of two genera Cryptococcus and Rhodotorula was high. None of the yeast isolates exhibited any resistance to the antifungal drugs tested; however, all pathogenic Cryptococcus species were positive for virulence determinants like urease activity, growth at 37°C, melanin production, the PLB and CAP genes. This is the first report on the molecular diversity of yeast species, particularly, Cryptococcus species and their virulence attributes in pigeon fecal droppings in Saudi Arabia.

Abstract
Background and Purpose: Naganishia albida (formerly Cryptococcus albidus) is a non-neoformans cryptococcal species rarely isolated as a human pathogen. Case report: Herein, we present the case of a 26-year-old Iranian man with a superficial cutaneous lesion in the axilla. The initial treatment for pityriasis versicolor by clotrimazole was unsuccessful. We performed skin sampling based on the standard protocol and conducted further investigations by the conventional laboratory tests and molecular analysis of the skin samples. All the mentioned analyses revealed N.albida as the causative agent of infection. The minimum inhibitory concentration (MIC) analysis was carried out for the isolated agent, and the patient was treated using 100 mg daily of oral itraconazole. Conclusion: N. albida can be the causative agent of some superficial infections. This is the first report on the successful detection and treatment of a superficial skin infection due to N. albida by oral itraconazole.

Abstract
Cryptococcus albidus is a saprophytic yeast linked to just 26 reports of human infection in the world literature. Here, we report the first case of C. albidus peritonitis, in a patient with end-stage renal disease and hepatitis C-associated cirrhosis who is on peritoneal dialysis. The patient was treated successfully with a week-long course of amphotericin B. Non-neoformans cryptococcal infections present a clinical challenge, because they are difficult to diagnose and lack established guidelines for treatment. We present a review of the literature on C. albidus infections and their treatment.

Abstract
We present the first case of encephalitis caused by Cryptococcus albidus duo to AIDS. In addition, we give an overview of the literature of extra-dermal infection cases caused by C. albidus. In the 21 cases, HIV and organ transplantation were important risk factors especially in recent 20 years. Fungal culture or India ink preparations are the best way to demonstrate C. albidus in both serum and CSF.
