In view of the increase in yeast infections, especiallypolymicrobial ones, differential culture media have acquired increasing importance. The presentstudy evaluated the Sabouraud chloramphenicol, Biggy agar, Pagano Levin agar and CHROMagarCandida media in terms of isolation, number of yeast colony forming units per plate,and inhibition of bacteria and(More)
Biocides play an important role in healthcare-associated infection control by either minimizing or preventing microorganism dissemination. This study evaluated the susceptibility of Pseudomonas aeruginosa clinical isolates to a quaternary ammonium (QAC) disinfectant and antibiotics, and verified the presence of qacEΔ1, a determinant of resistance to QAC.(More)
INTRODUCTION Rhodococcus equi is an opportunistic pathogen, causing rhodococcosis, a condition that can be confused with tuberculosis. Often, without identifying M. tuberculosis, physicians initiate empiric treatment for tuberculosis. R. equi and M. tuberculosis have different susceptibility to drugs. Identification of R. equi is based on a variety of(More)
Cryptococcus gattii causes a form of endemic mycosis that most commonly affects the lungs and central nervous system of immunocompetent patients living in tropical and subtropical areas of the world. Case report. A 66-year-old man who had chronic obstructive pulmonary disease without HIV infection and had been on systemic corticotherapy for several years(More)
Abilith of Candida spp to secrete extracellular enzymes and slime has been associated as pathogenicity factors. Out of a total of 37 strains of Candida sp, 100% were proteinase producers, 83.8% were phospholipase producers, 64.9% were slime producers and 100% were sensitive to fluconazole and itraconazole. Seventeen typings (enzymes/slime) were found. This(More)
Fifty yeasts belonging to the genera Candida, Pichia, Saccharomyces, Cryptococcus, Rhodotorula and Trichosporon were identified by classical methods and by the API 20C AUX system. The commercial system correctly identified 92% of the species, with the need for additional tests in 16% of cases. The results were interpreted with good, very good and excellent(More)
