Minor species of the Candida albicans complex may cause overestimation epidemiology C. albicans, and misidentifications could mask their implication in human pathology. Authors determined occurrence minor (C. africana, dubliniensis stellatoidea) among Yaoundé HIV-infected patients, Cameroon. Stool, vaginal discharge, urine oropharyngeal samples were analysed by mycological diagnosis. Isolates identified conventional methods mass spectrometry (MS; carried out matrix-assisted laser...

Cryptococcal meningitis is a severe opportunistic infection in HIV-infected patients. In Ivory Coast, despite the availability of antiretroviral treatment (ART), this still prevalent. The study investigates genetic diversity 363 clinical isolates Cryptococcus from 61 Ivorian HIV-positive patients, occurrence mixed infections and vitro antifungal susceptibility isolates. Serotyping was performed via LAC1 CAP64 gene amplification. Genotyping using phage M13 core (GACA)4 (GTG)5 primers...

Fungi belonging to the Cryptococcus genus and related genera (Filobasidium, Holtermanniella, Naganishia, Papiliotrema, Solicoccozyma, Vishniacozyma) are encapsulated yeasts found in either environment or animal sources. However, precise biotopes of most species remain poorly defined. To assess whether wild birds from southern France can carry spread pathogenic (i.e., C. neoformans gattii complexes), as well lesser-studied (non-neoformans/gattii former spp.), 669 89 received for care over a...

Cross-resistance to medical azoles by exposure azole pesticides is well documented for Aspergillus family fungi but poorly evaluated other environmental pathogen fungi, particularly yeasts belonging the Cryptococcus neoformans/Cryptococcus gattii species complexes.One thousand C. neoformans yeast were exposed various concentrations of seven different commonly used pesticides. Clones surviving picked randomly, and their minimal inhibitory (MICs) fluconazole, voriconazole, posaconazole,...

Neuromeningeal cryptococcosis is a life-threatening infection of the central nervous system, caused by encapsulated yeast belonging to Cryptococcus neoformans and gattii species complexes. Recent data showed that virulence antifungal resistance are variable for yeasts C. complex. There an increase in fluconazole complex according genotype. In present study, (i) we explored compared mechanisms between deuterogattii clinically resistant strains induced fluconazole-resistant exposure vitro,...

Cryptococcal meningitis (CM) may be caused by several species of Cryptococcus.We describe a fatal case CM in HIV-positive patient from Ivory Coast infected Cryptococcus neoformans VNI and Cryptococcusdeuterogattii. Isolates were recovered cerebrospinal fluid (CSF) prior to systemic antifungal treatment. Six isolates studied (the entire culture plus five isolated colonies it). Serotyping was performed via LAC 1 CAP 64 gene amplification. Genotyping using restriction fragment length...

Cryptococcal meningitis is a dreadful opportunistic fungal infection amongst human immunodeficiency virus (HIV)-infected patients. One complication in the management of disease possible patient by two or more different strains Cryptococcus neoformans. This study investigated intra-individual genetic diversity and antifungal susceptibility C. neoformans isolates from Yaoundé (Cameroon) HIV-infected patients with cryptococcal meningitis.

Fluconazole (FCZ), either alone or in combination, is often administered for treatment of cryptococcal meningitis, especially sub-Saharan Africa. Its extensive use has led to the emergence FCZ-resistant strains. The mechanisms underlying FCZ resistance are poorly documented yeasts belonging Cryptococcus gattii species complex. literature suggests that could be due mutations and/or overexpression ERG11 gene (encoding 14-α-demethylase) and efflux pumps such as MDR AFR (two subclasses ABC...
