Vultures from different trophic guilds show distinct oral pathogenic yeast signatures and co-occurrence networks.

Sci Total Environ 2020 Jun 23;723:138166. Epub 2020 Mar 23.

Department of Evolutionary Ecology, National Museum of Natural Sciences, Spanish Research Council (CSIC), Madrid, Spain.

Vultures have evolved adaptive mechanisms to prevent infections associated with their scavenging lifestyle. However, food-borne exposure to antimicrobial pharmaceuticals can promote opportunistic infections with adverse outcomes. Here, we used multivariate and network analyses to increase understanding of the behavior of the yeast communities causing oral mycosis outbreaks recently reported in wild nestling cinereous (Aegypius monachus), griffon (Gyps fulvus) and Egyptian (Neophron percnopterus) vultures (CV, GV and EV, respectively) exposed to antibiotics from livestock farming.

for the Evaluation of Antifungal Efficacy against Medically Important Fungi, a Narrative Review.

Microorganisms 2020 Mar 11;8(3). Epub 2020 Mar 11.

EA Dynamyc UPEC, EnvA, USC Anses, Faculté de Médecine de Créteil, 94000 Créteil, France.

The treatment of invasive fungal infections remains challenging and the emergence of new fungal pathogens as well as the development of resistance to the main antifungal drugs highlight the need for novel therapeutic strategies. Although in vitro antifungal susceptibility testing has come of age, the proper evaluation of therapeutic efficacy of current or new antifungals is dependent on the use of animal models. Mammalian models, particularly using rodents, are the cornerstone for evaluation of antifungal efficacy, but are limited by increased costs and ethical considerations. Read More

N,N,N',N'-tetrakis(2-pyridylmethyl)ethylenediamine, a zinc chelator, inhibits biofilm and hyphal formation in Trichosporon asahii.

BMC Res Notes 2020 Mar 10;13(1):142. Epub 2020 Mar 10.

Department of Microbiology, Meiji Pharmaceutical University, 2-522-1 Noshio, Kiyose, Tokyo, 204-8588, Japan.

Objective: Trichosporon asahii is the major causative fungus of disseminated or deep-seated trichosporonosis and forms a biofilm on medical devices. Biofilm formation leads to antifungal drug resistance, so biofilm-related infections are relatively difficult to treat and infected devices often require surgical removal. Therefore, prevention of biofilm formation is important in clinical settings. Read More

A case of Trichosporon asahii urinary tract infection in a frail elderly patient.

Infez Med 2019 Mar;27(1):93-96

Dipartimento Scienze di Laboratorio e Infettivologiche, Fondazione Policlinico Universitario A. Gemelli IRCCS, Rome, Italy; Istituto di Clinica delle Malattie Infettive, Universitá Cattolica del Sacro Cuore, Rome, Italy.

Trichosporon urinary tract infection (UTI) is an unusual emerging infection, caused mostly by Trichosporon asahii, described especially in hospitalized patients. To date the interpretation and management of Trichosporon positive urinary culture remains a diagnostic and therapeutic dilemma for which there are no precise indications, and the challenge can be even more complicated in comorbid frail elderly patients. Triazoles are known to be the most effective antifungal drugs but can raise concerns about pharmacological interaction. Read More

Department of Pathology and Legal Medicine, School of Medicine, Specialized Medical Mycology Center, Postgraduate Program in Medical Microbiology, Federal University of Ceará, Fortaleza-CE, Brazil; School of Veterinary, Postgraduate Program in Veterinary Science, State University of Ceará, Fortaleza-CE, Brazil.

Trichosporon spp. have been increasingly recognized as an important pathogen of invasive and disseminated infections in immunocompromised patients. These species are prone to form biofilms in medical devices such as catheters and prosthesis, which are associated with antifungal resistance and therapeutic failure. Read More

Matrix-assisted laser desorption/ionization time-of-flight mass spectrometric identification and antifungal susceptibility analysis of Candida species isolated from patients with invasive yeast infections in five university hospitals.

Braz J Microbiol 2019 Jan 4;50(1):99-105. Epub 2018 Dec 4.

Department of Clinical Microbiology Laboratory, The First Affiliated Hospital of Soochow University, No. 188 Shizi Street, Soochow, 215006, China.

In this multicenter study, we compared the performance of the Bruker Biotyper MS system and VITEK 2 YST systems for invasive yeast identification, investigated the distribution of isolated species, and evaluated the antifungal susceptibility profiles of Candida albicans, Candida parapsilosis, and Candida tropicalis. In cases of discrepant results lack of identification with either method, molecular identification techniques were employed. We tested 216 clinical isolates, and concordance between the two methods was observed for 192/216 isolates (88. Read More

Deep cutaneous infection in a patient recovering from toxic epidermal necrolysis.

Med Mycol Case Rep 2019 Mar 26;23:26-28. Epub 2018 Oct 26.

Brooke Army Medical Center, 3551 Roger Brooke Drive, San Antonio, TX, USA.

Patients with toxic epidermal necrolysis, a condition that causes full thickness epidermal necrosis that affects over 30% of the skin surface and mucosal membranes, often develop comorbid infections throughout the recovery of the disease [1]. While most commonly these are related to a bacterial source, infections due to viral, mycobacterial, and rarely fungal organisms occur. We present a case of a patient who developed a deep cutaneous fungal infection caused by Trichosporon asahii and discuss the management. Read More

Department of Microbiology, Jagadguru Sri Shivarathreeshwara Medical College, Mysore, Karnataka, India.

Urinary tract infections (UTIs) caused by fungi, frequently associated with medical devices, have increased and caused great morbidity and mortality among hospitalized patients. Difficulties on different species identification as well as the lack of standardized sensitivity tests , contribute to the limited information available on epidemiology, diagnosis, and therapeutics of infections. There are only sporadic reports of UTI caused by reported from India. Read More

Department of Microbiology, Sri Ramachandra Institute of Higher Education and Research, Chennai, Tamil Nadu, India.

Background: Invasive infections due to spp. have increased recently and are frequently associated with indwelling medical devices. Such infections which are associated with biofilm formation do not respond to the routinely used antifungal agents and are often persistent, associated with high mortality rate. Read More

J Cutan Pathol 2019 Feb 18;46(2):159-161. Epub 2018 Dec 18.

Department of Dermatology, Columbia University Medical Center, New York, New York.

We report a case of disseminated Trichosporon asahii in a patient on systemic antifungal therapy who presented with multiple cutaneous nodules suggestive of fungal infection. Histologic features resembled neutrophilic eccrine hidradenitis but staining with periodic acid-Schiff and Gomori methenamine silver confirmed the clinical diagnosis. This case highlights the importance of maintaining suspicion for trichosporonosis and contextualizing histologic findings within the underlying clinical picture. Read More
