【 摘 要 】

The etiology of the diarrheic process in AIDS may be caused by viruses, bacteria, fungi, protozoa or helminths, as well as HIV itself. This study evaluated enteropathogens relating to diarrhea in HIV patients who were on antiretroviral therapy. The parasitological methods used were Faust, Hoffmann and Kinyoun. Isolation and culturing of fungi were carried out in accordance with the methodology recommended by the NCCLS M27-A standard. The yeast species were identified using the polymerase chain reaction (PCR). Bacteria were isolated on MacConkey and SS agar and the species were identified using Enterokit B (Probac do Brasil) and biochemical methods. Forty-nine patients were evaluated: 44.89% presented enteroparasites and 48.1% presented Candida sp, of which 61.5% were Candida albicans, 7.6% were Candida sp and 30.7% were Candida non-albicans. Bacteria were isolated from 72% of the patients, of which 49% were Escherichia coli, 13% Salmonella parathyphi, Klebsiella sp or Proteus and 6% Citrobacter freundii or Yersinia sp. There was high prevalence of Candida sp in HIV patients with diarrhea and non-albicans species were isolated. Their presence could be taken to mean that they were accomplices in or causes of the infection.
