Drug resistance of yeasts isolated from oropharyngeal candidiasis in aids patients Rev. Microbiol.
Silva,Maria do Rosário Rodrigues; Paula,Claudete Rodrigues de; Silva,Soraya Cristina; Costa,Théo Rodrigues; Costa,Márcio Rodrigues.
Candida spp was isolated from 59 (68.60%) out of eighty six samples of oral mucosa of AIDS patients. The identification, based or the production of a germ tube and chlamydospores, and on the assimilation and fermentation of carbohydrates, revealed 52 strains (88.13%) of C. albicans, 4 (6.77%) of C. tropicalis and 3 (5.08%) of C. krusei. The susceptibility of these strains to amphotericin B, flucytosine, itraconazole, fluconazole and ketoconazole was determined using the agar dilution method. Comparing the minimum inhibitory concentration values found in the susceptibility test with the serum levels achieved by these drugs, only 8.47% and 5.08% of the yeasts strains proved to be resistant to amphotericin B and flucitosyne, respectively. A high frequency of...

In vitro efficiency of disinfectants against salmonella enteritidis samples isolated from broiler carcasses Rev. Bras. Ciênc. Avic.
Cardoso,MO; Ribeiro,AR; Santos,LR; Borsoi,A; Pilotto,F; Rocha,SLS; Nascimento,VP.
The threat to public health represented by Salmonella is at least partially a consequence of its ecology in poultry hosts. Good manufacturing practices in the processing plant can reduce the contamination of poultry products, and critical control point principles are essential throughout the chain production. One procedure adopted in critical points control to prevent and to reduce Salmonella in farms and poultry products is the use of disinfectants. This study aimed at evaluating disinfectant efficiency against Salmonella enteritidis samples isolated from broiler carcasses in Rio Grande do Sul State between 1995 and 1996. The tested disinfectants were: phenol 1:256, quaternary ammonium 1:2500, glutaraldehyde 1:200, and iodine 1:500, with contact times of...
