Al-Shaarani AAQA, Quach ZM, Wang X, Muafa MHM, Nafis MMH, Pecoraro L. Analysis of Airborne Fungal Communities on Pedestrian Bridges in Urban Environments. Microorganisms 2023; 11:2097. [PMID: 37630657 PMCID: PMC10458245 DOI: 10.3390/microorganisms11082097] [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: 06/02/2023] [Revised: 07/31/2023] [Accepted: 08/09/2023] [Indexed: 08/27/2023] Open
Abstract
Airborne fungal spores constitute an important type of bioaerosol and are responsible for a number of negative effects on human health, including respiratory diseases and allergies. We investigated the diversity and concentration of culturable airborne fungi on pedestrian bridges in Tianjin, China, using an HAS-100B air sampler. We compared the airborne fungal communities at the top central area of the selected pedestrian bridges and along the corresponding sidewalk, at ground level. A total of 228 fungal strains belonging to 96 species and 58 genera of Ascomycota (68.86%), Basidiomycota (30.26%), and Mucoromycota (0.88%) were isolated and identified using morphological and molecular analysis. Alternaria was the dominant genus (20.61%), followed by Cladosporium (11.48%), Schizophyllum (6.14%), Sporobolomyces (5.70%), and Sporidiobolus (4.82%). Alternaria alternata was the most frequently occurring fungal species (6.58%), followed by Schizophyllum commune (5.26%), Alternaria sp. (4.82%), Sporobolomyces carnicolor (4.39%), and Cladosporium cladosporioides (3.95%). The recorded fungal concentration ranged from 10 to 180 CFU/m3. Although there was no significant difference in the distribution and abundance of the dominant airborne fungal taxa between the two investigated bridges' sites, numerous species detected with a low percentage of abundance belonging to well-known pathogenic fungal genera, including Alternaria, Aspergillus, Aureobasidium, Cladosporium, Penicillium, and Trichoderma, were exclusively present in one of the two sites. The relative humidity showed a stronger influence compared to the temperature on the diversity and concentration of airborne fungi in the investigated sites. Our results may provide valuable information for air quality monitoring and for assessing human health risks associated with microbial pollution.

Abstract
RATIONALE Fungal infection is common and difficult to be diagnosed timely in clinical, for its various kinds and similar manifestations. The rare pulmonary fungal infection such as Schizophyllum commune was one of the harder ones and misdiagnosed in usual. PATIENT CONCERNS We report a 32-year-old female which was diagnosed with Metagenomic Next-Generation Sequencing (mNGS). She was hospitalized with the complaint of 4 months and more of repeated cough and expectorating. The chest computer tomography revealed left lower lobe pathological changes, but antibiotics were ineffective. No positive results were found in laboratory tests, including sputum culture and the pathology of lung puncture biopsy. DIAGNOSES mNGS of lung biopsy was performed and detected the sequence number of Schizophyllum for 11. INTERVENTIONS The patient was treated with voriconazole and itraconazole successively. OUTCOMES She recovered to health. There was no recurrence during follow-up. LESSONS mNGS as a diagnostic method could quickly detect pathogens through the processing of fragment, synthesis, comparison, and analysis of sample genes. It is suitable for detecting especially rare and polymicrobial infections. To our best knowledge, infection of Schizophyllum commune have not been reported in English literature with diagnostic method of mNGS.

Med Mycol 2023; 61:6967136. [PMID: 36592959 PMCID: PMC9874029 DOI: 10.1093/mmy/myac098] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2022] [Revised: 12/12/2022] [Accepted: 12/30/2022] [Indexed: 01/04/2023] Open
Abstract
Due to an increasing number of patients at risk (i.e., those with a highly compromised immune system and/or receiving aggressive chemotherapy treatment), invasive fungal infections (IFI) are increasingly being reported and associated with high mortality rates. Aspergillus spp., particularly A. fumigatus, is the major cause of IFI caused by filamentous fungi around the world followed by Fusarium spp., however, other fungi are emerging as human pathogens. The aim of this study was to explore the epidemiology and prevalence of the non-Aspergillus and non-Fusarium filamentous fungi in human clinical samples over an 11-year period in Qatar using molecular techniques. We recovered 53 filamentous fungal isolates from patients with various clinical conditions. Most patients were males (75.5%), 9.4% were immunocompromised, 20.7% had IFI, and 11.3% died within 30 days of diagnosis. The fungal isolates were recovered from a variety of clinical samples, including the nasal cavity, wounds, respiratory samples, body fluids, eye, ear, tissue, abscess, and blood specimens. Among the fungi isolated, 49% were dematiaceous fungi, followed by Mucorales (30%), with the latter group Mucorales being the major cause of IFI (5/11, 45.5%). The current study highlights the epidemiology and spectrum of filamentous fungal genera, other than Aspergillus and Fusarium, recovered from human clinical samples in Qatar, excluding superficial infections, which can aid in the surveillance of uncommon and emerging mycoses.

Abstract
BACKGROUND The pathogenic fungus Schizophyllum sp. can cause allergic fungal rhinosinusitis and allergic bronchopulmonary mycosis in humans. Sinus and lung infections due to Schizophyllum sp. have been reported globally; however, no case of hypertrophic pachymeningitis due to this pathogen has been reported yet. Herein, we describe for the first time, a case of hypertrophic pachymeningitis due to Schizophyllum sp. CASE PRESENTATION A 69-year-old woman visited the hospital with chief complaints of headache, right trigeminal neuralgia (third branch), ataxic gait, and deafness in the right ear. Magnetic resonance imaging revealed a tumor in the right sphenoidal sinus and thickening of the dura mater surrounding the right porus acusticus internus. Endoscopic sinus surgery and neuroendoscopic biopsy were performed to remove sinus lesions and intracranial lesions, respectively. Both pathological specimens showed findings indicative of filamentous fungi on Grocott's staining. DNA sequencing with the sinus specimen revealed Schizophyllum sp. as the causative pathogen, consistent with the diagnosis of fungal sinusitis and hypertrophic pachymeningitis. Intravenous liposomal amphotericin B was started, but owing to lack of improvement, the treatment was switched to intravenous voriconazole. We observed improvements in both radiological findings and symptoms. However, the symptoms exacerbated again when the trough level of voriconazole decreased. Upon increasing the voriconazole dose, a higher trough level was obtained and the symptoms improved. CONCLUSION Our study suggests that when symptoms of central nervous system infection due to Schizophyllum sp. do not improve with liposomal amphotericin B, voriconazole can be administered at high trough levels to improve the symptoms.

Abstract
Schizophyllum commune is a basidiomycetes worldwide distributed that has emerged as cause of invasive infections in immunosuppressed patients. We present a case of a man who was simultaneously diagnosed with a small cell non-Hodgkin lymphoma and a sphenoid sinusitis by S. commune. Intraoperative observation and histology description were crucial to consider an alternative diagnosis to mucormycosis suggested by the MRI. The diagnosis was made based on PCR identification and sequencing.
