Human and animal fungal pathogens are a growing threat worldwide leading to emerging infections creating new risks for established ones. There is need rapid accurate identification of enable early diagnosis targeted antifungal therapy. Morphological biochemical methods time-consuming require trained experts. Alternatively, molecular methods, such as DNA barcoding, powerful easy tool monophasic identification, offer practical approach species less demanding in terms taxonomical expertise....
Sporothrix ( Ophiostomatales ) comprises species that are pathogenic to humans and other mammals as well environmental fungi. Developments in molecular phylogeny have changed our perceptions about the epidemiology, host-association, virulence of . The classical agent sporotrichosis, schenckii , now several nested a clinical clade with S. brasiliensis globosa luriei To gain more precise view outbreaks dynamics, structure, origin genetic variation within among populations we applied three sets...
ABSTRACT Sporothrix schenckii isolates of fixed and lymphocutaneous clinical forms from Mexico (MX), Guatemala (GT), Colombia (CO) as well environmental MX were studied by analyzing their phenotypic characteristics (conidial length, thermotolerance percent growth inhibition [GI] at 35 37°C, median lethal dose [LD 50 ]) genotypic (by random amplified polymorphic DNA [RAPD] analysis-PCR). A significant difference ( P < 0.01) in the mean conidial length S. CO x̅ = 4.03 ± 1.04 μm) compared...
Sporothrix schenckii is the etiological agent of sporotrichosis, a subcutaneous mycosis and an emerging disease in immunocompromised patients. Adherence to target cells prerequisite for fungal dissemination systemic complications. However, information on cell surface components involved this interaction rather scarce. In investigation, extraction isolated walls from yeast phase S. with SDS separation proteins by SDS-PAGE led identification periodic acid-Schiff (PAS)-reacting 70 kDa...
The effect of three strains the fungus Beauveria bassiana (Balsamo) Vuillemin and two Metarhizium anisopliae (Metschnikoff) Sorokin upon coffee berry borer, Hypothenemus hampei (Ferrari), was studied in farms at different altitudes (450–1,100 m above sea level) Soconusco, Chiapas, Mexico. maximum average percentage mycosis varied according to altitude. At 450 asl (El Rincon) 14.3% for B. 6.3% M. anisopliae; 880 (Santa Anita) 40.6% 12.6% anisopliae, 1,100 (Alpujarras) 33.9% 22. l% anisopliae....
Histoplasma capsulatum was isolated from gut, lung, liver, and spleen of 17 208 captured bats belonging to 6 different genera species. Three the infected were State Guerrero 14 Morelos. All adult bats: males (1 Pteronotus parnellii, 2 Natalus stramineus, Artibeus hirsutus, 1 Leptonycteris nivalis) 11 females Myotis californicus, Mormoops megalophylla, 8 A. L. nivalis). High rates bat infection with H. found in monitored sites N. nivalis should be considered as first records world. The fungus...
We utilized two-dimensional gel electrophoresis and immunoblotting (2D-immunoblotting) with anti-Sporothrix schenckii antibodies to identify antigenic proteins in cell wall preparations obtained from the mycelial yeast-like morphologies of fungus. Results showed that a 70-kDa glycoprotein (Gp70) was major antigen detected both 60-kDa present only cells. In addition Gp70, filament cells four molecular weights 48, 55, 66 67 kDa, some which exhibited several isoforms. To our knowledge, this is...
Chagas disease is a key health problem in Latin America and caused transmitted by Trypanosoma cruzi triatomine bugs, respectively. Control of triatomines has largely relied on the use pyrethroids, which proved to be ineffective long term. Alternatively, entomopathogenic fungi been implemented control bugs. These are highly efficient as they induce reduction immune response insects. Meccus pallidipennis main vector Mexico. In this work we investigated effects two fungi, Metarhizium anisopliae...
Nosocomial invasive fungal infections, particularly aspergillosis, are an increasing problem in immunocompromised patients. The presented study evaluates diversity and the presence of Aspergillus air samples from two hospitals.Over course one year (rainy dry seasons), was sampled three areas hospitals (1 2) using a single-stage Andersen viable particle sampler (Thermo Scientific, Waltham, MA, USA). fungi were identified by macro- micromorphology, number colony forming units (CFU)/m(3) their...
Objectives Disseminated histoplasmosis is an AIDS-defining illness. Histoplasmosis commonly misdiagnosed as tuberculosis. Nigeria has the second highest number of people living with HIV/AIDS in Africa. The present study was carried out to investigate prevalence skin sensitivity amongst Nigerians histoplasmin. Design A cross-sectional conducted six centres across five geopolitical zones Nigeria. Methods We recruited both healthy non-HIV and HIV-positive adults CD4 count ≥ 350 cells/mm3...
Cell wall (CW) components of fungus Sporothrix schenckii are the major inductors antigens immune responses. The immunodominant 60 kDa glycoprotein (gp60) has been shown to be associated with virulence this but its role in experimental sporotrichosis is unknown. In work, immunological effects CW-purified gp60 were investigated a model subcutaneous normal and gp60-preimmunized C57BL/6 BALB/c mice strains which then infected S. conidia. Results showed that both use different cytokine profiles...
Up to now, 30 mitochondrial DNA(mtDNA)and 4 rDNA types of Sporothrix schenckii strains have been identified. Here, seventy-six isolates S. from Mexico, Guatemala, Brazil, Thailand and India were genotyped studied epidemiologically by mtDNA restriction fragment length polymorphisms(RFLP)and internal transcribed spacer region(ITS)-RFLP analysis two new types, Type 31 32, found. 30, previously reported Mora-Cabrera et al. was confirmed be 3 designated as blank. Of 48 41 belonged Group A wherein...
Sporotrichosis is the most common implantation mycosis caused by several species of Sporothrix schenckii complex. The gold standard for diagnosis concerned with isolation fungus; although, fresh examinations, staining, and biopsies are also helpful this purpose. sporotrichin an antigenic complex comprised a peptide-rhamnomannan, which relevant respect to pathogenic fungi; it primarily used serological skin testing. We present study regarding use as diagnostic aid cutaneous sporotrichosis....
