It was recently proposed that Candida parapsilosis represents a complex composed of three closely related species, i.e., C. parapsilosis sensu stricto, C. orthopsilosis, and C. metapsilosis. The aim of this study was to describe the distribution of C. parapsilosis complex isolates among clinical samples. We also evaluated antifungal susceptibility profiles, in vitro presence of lipase and secre...

Proteolytic activities in alfalfa weevil (Hypera postica) larval midguts have been characterized. Effects of pH, thiol activators, low-molecular weight inhibitors, and proteinase inhibitors (PIs) on general substrate hydrolysis by midgut extracts were determined. Hemoglobinolytic activity was highest in the acidic to mildly acidic pH range, but was maximal at pH 3.5. Addition of thiol-activator...

objective: the secreted aspartic proteinases (sap2) of candida albicans has prominent role on candida adherence, invasion, and pathogenicity. the aim of this study was cloning, expression and characterizing of sap2 enzyme. also in this study for the first time, the expression system p. pasturis was used for expressing the recombinant protein. materials and methods: c. albicans sap2 gene was am...

Oropharyngeal candidiasis (OPC) is the most common opportunistic infection in HIV-infected patients and is considered a clinical marker of disease progression (3). A reduction in the incidence of OPC and some cases of resolution of refractory mucosal candidiasis following introduction of HIV protease inhibitor (HIV-PI) therapy have recently been reported (6, 10, 11). To switch from saprophytic ...
