Eighty Candida albicans strains, isolated from throat of patients at the Universitary Clinic of the Faculty of Superior Studies Iztacala of the National Autonomous University of Mexico, were analyzed. They were identified by microscopic and colony morphologies, germ tube test, and by auxanogram and zimogram. Minimal inhibitory concentrations (MIC) of 5-fluorocytosine, miconazole and amphoterici...

The antifungal activity of jaritin and haloprogin against Candida albicans is similar. In vitro they had less activity than clotrimazole and miconazole, but the activity was independent of inoculum size.

The purpose of this study was to investigate the antimicrobial effect of a Punica granatum Linn (pomegranate) phytotherapeutic gel and miconazole (Daktarin oral gel) against three standard streptococci strains (mutans ATCC 25175, sanguis ATCC 10577 and mitis ATCC 9811), S. mutans clinically isolated and Candida albicans either alone or in association. The effect of minimum inhibitory concentrat...

Fungi, in comparison with other pathogenic factors, have high pathogenicity. The number of fungal species which are able to infect people is over 500. The upper respiratory tract and ear have permanent contact with external environment which makes their ontocenoses open to continuous exchange of microorganisms of which they consist. In etiology of inflammatory processes 21 species which belongi...

In this work, we report that flavohemoglobin contributes to the azole susceptibility of Staphylococcus aureus. We first observed that deletion of the flavohemoglobin gene leads to an increase in the viability of imidazole-treated S. aureus cells and that reversion to the wild-type phenotype occurs upon expression of flavohemoglobin from a multicopy plasmid. Further spectroscopic analyses showed...

The constitutive androstane receptor (CAR) and the pregnane X receptor (PXR) play a major part in the control of drug metabolism and transport. We have previously shown that PXR and CAR expression is controlled by the glucocorticoid receptor (GR) and proposed the existence of a signal transmission cascade GR-(PXR/CAR)-drug metabolizing and transporter systems. In the current study, we investiga...

Nateglinide is an antidiabetic agent metabolized by CYP2C9 and CYP3A4; hence inhibitors of these CYP isozymes may interact with nateglinide. There are, however, only limited in vitro data on how to predict drug-drug interactions in vivo. We examined the effects of 18 drugs that may be prescribed together with nateglinide (metformin, buformin, aspirin, gemfibrozil, simvastatin, pioglitazone, ros...
