Veronaea botryosa has been identified as a pathogen of cultured white sturgeon Acipenser transmontanus. In 2015, samples from 19 white sturgeon were received for diagnosis, of which 14 cultured positive for V. botryosa. Intraspecific variability among V. botryosa isolates from different clinically affected hosts and geographic regions was investigated using repetitive extragenic palindromic PCR fingerprinting (rep-PCR). The rep-PCR profiles of 16 V. botryosa isolates from a human, sea turtles, and cultured fish were distinct from those of other phaeoid fungi belonging to the genera Cladophialophora and Exophiala...

Understanding the molecular mechanisms regulating the fruiting process in macro-fungi, especially industrially cultivated mushrooms, has long been a goal in mycological research. To gain insights into the events accompanying the transformation of mycelia into fruit-bodies in Flammulina velutipes, proteins expressed characteristically and abundantly at primordium and fruit-body stages were investigated by using the iTRAQ labeling technique. Among the 171 differentially expressed proteins, a total of 68 displayed up-regulated expression levels that were associated with 84 specific KEGG pathways...

Several pathogenic fungi and cases related to Japanese medical mycologists were reviewed. Trichosporon inkin (as Sarcinomyces inkin) was reported as a pathogen of scrotal lesion by Oho in 1921, and Trichosporon asahii was isolated from generalized keratotic lesions in 1922 by Akagi in Japan. They were once included in Trichophyton beigelii, but then based on revision using DNA molecular technology, were returned to their original names.Microsporum ferrugineum was reported by Ota as a causative dermatophyte of tinea capitis in Japan and surrounding areas...

Invasive aspergillosis has been studied in laboratory by the means of plethora of distinct animal models. They were developed to address pathophysiology, therapy, diagnosis, or miscellaneous other concerns associated. However, there are great discrepancies regarding all the experimental variables of animal models, and a thorough focus on them is needed. This systematic review completed a comprehensive bibliographic analysis specifically-based on the technical features of rodent models infected with Aspergillus fumigatus...

Subcutaneous phaeohyphomycosis is a form of infection caused by dematiaceous fungi and frequently reported in the literature. It is considered as an emerging mycosis because it is increasingly reported among immunosuppressive patients. The most commonly cited etiologic agent is Exophiala jeanselmei, followed by Alternaria spp. We present a case of a 48-year-old woman, with a history of lepromatous leprosy, using corticosteroid in immunosuppressive doses due to a type 2 repetitive reaction leprosy outbreak, revealing subcutaneous phaeohyphomycosis lesions...

"Paracoccidioidomycosis ceti" is a rare zoonotic fungal infection affecting dolphins and is endemic worldwide. The causative agents are Paracoccidioides species; however, it is impossible to isolate the fungal species. We isolated Trichosporon asteroides from multifocal, irregularly raised skin lesions on a female bottlenose dolphin (Tursiops truncatus) captured off coast of Japan, which was suspected to have "paracoccidioidomycosis ceti." An abundance of round, yeast-like cells was detected in a potassium hydroxide direct-mount specimen of the skin samples; however, nested PCR targeting the partial sequence of 43-kDa glycoprotein-coding gene correspondent to Paracoccidioides sp...

BACKGROUND: Worldwide, dermatophytic infections are running a chronic course either due to ineffective treatment or emerging drug resistance. In the past three decades, there has been an increase in incidence and non-responsiveness to conventional antifungals, which suggests that there is a need of antifungal sensitivity testing. AIMS: This study was aimed at identifying clinico-mycological pattern of dermatophytic infections in patients attending thedermatology outpatient department of a tertiary care hospital, and to obtain the sensitivity pattern of isolates against six commonly used oral antifungals (fluconazole, terbinafine, itraconazole, ketoconazole, griseofulvin and voriconazole)...

REVIEW
Jeannette Guarner
The discovery of HIV was largely due to the presence of Pneumocystis pneumonia (PCP) in young patients that did not have the usual known causes of immune deficiencies in the early 1980s. Currently, treatment with highly active anti-retroviral therapy (HAART) and the use of prophylaxis for PCP have lowered the frequency of fungal infections; however, these infections continue to cause morbidity and mortality in those patients that fall out or are not in care. The frequency of specific fungal diseases in HIV patients will depend on the prevalence of fungi in the particular geographic location...
