Sporothrix schenckiiwas reclassified as a complex encompassing six cryptic species, which calls for the reassessment of clinical and epidemiological data of these new species. We evaluated the susceptibility of Sporothrix albicans(n = 1) , S. brasiliensis(n = 6) , S. globosa(n = 1), S. mexicana(n = 1) and S. schenckii(n = 36) to terbinafine (TRB) a...
Real-time PCR based on the recN and gyrB genes was developed to detect four Streptococcus bovis/Streptococcus equinus complex (SBEC) subspecies from rectal swab specimens. The overall prevalence was 35.2%: Streptococcus gallolyticus subsp. gallolyticus (11.1%), S. gallolyticus subsp. pasteurianus (13%),
Streptococcus infantarius subsp. coli (20.4%...
We studied 40 strains of the species complex formerly classified as the single species Sporothrix schenckii to identify new species within this complex and evaluate their antifungal susceptibility profiles. Based on phenotypic tests
(ability to grow at 37°C, colony diameters, and pigmentation of the colonies, as well as assimilation of sucrose and...
The phospholipase activity in Candida albicans and Candida dubliniensis isolated from oral candidiasis cases were studied.
The phospholipase activity was evaluated in egg yolk agar.
All the C. albicans isolates (n = 48) showed phospholipase activity (mean Pz = 0.66). However, none of the C. dubliniensis isolates (n = 24) showed this activity.
The a...
Here, a microdilution technique based on the M27-A2 protocol (NCCLS, 2002) was employed to compare the susceptibilities of Candida albicans and Candida dubliniensis to essential oils extracted from plants used as spices. The chemical compositions of the essential oils were defined based on the analysis of retention indices obtained by gas chromatog...
O genero Malassezia compreende fungos leveduriformes lipofilicos e lipodependentes que recentemente sofreram mudancas em sua classificacao taxonomica, com a introducao de quatro novas especies: M. globosa, M. obtusa, M. slooffiae e M. restricta, alem das especies M. furfur, M. pachydermatis e M. sympodialis, anteriormente descritas. Estes fungos es...
Susceptibility to amphotericin B was compared between isolates of Candida spp that were obtained from candidemia cases as follows: 41 from Hospital Universitário de Santa Maria, 56 from Hospital de Clínicas, Porto Alegre, and 47 from the Santa Casa hospital complex, Porto Alegre. The tests were based on the document M27-A2 from the Clinical Laborat...
A elevada utilizacao de agrotoxicos, sem os devidos cuidados, tem contribuido em muito para oaumento das intoxicacoes ocupacionais, sendo hoje, um dos principais problemas de saude publica no meio rural brasileiro. Entre os pesticidas mais utilizados estao os compostos pertencentes acategoria dos organofosforados que sao inibidores da acetilcolines...
