Genetic diversity among 37 isolates of the sorghum anthracnose pathogen Colletotrichum graminicola, from four geographically distinct regions of Brazil, was evaluated by RAPD and RFLP-PCR markers and virulence characters on a set of 10 differential sorghum genotypes. Twenty-two races were identified and race 13B was the most frequent, but present in only(More)
Vinte amostras de espécies de fungos, agentes da helmintosporiose em cereais, foram obtidas de diferentes regiões geográficas, sendo nove constituídas de Bipolaris oryzae, isoladas de cultura do arroz (Oryza sativa), sete de B. sorokiniana coletadas de trigo (Triticum aestivum), duas de B. maydis e duas de Exserohilum turcicum provenientes de milho (Zea(More)
Thirteen strains of the genus Candida were isolated from catheter, urine and surgical wounds from individual patients of the Santa Casa de Misericórdia, Belo Horizonte, MG, Brazil. Ten strains were characterized as Candida albicans, two as Candida glabrata, and one as Candida parapsilosis. Isolates were evaluated for molecular relatedness by random(More)
The increase in the number of infections caused by Candida species and the consequent use of antifungal agents favours an increase of resistant isolates. The aim of this study was to evaluate the antifungal susceptibility of Candida spp. isolates from patients with different systemic predisposing factors to candidosis. Seventy-nine Candida spp. isolates(More)
