[EVALUATION OF NUTRIENT MEDIA TO GROW SOME INFECTION DISEASES CAUSATIVE AGENTS].

The detection methods for microbial agents that have eidemiological significance are diversity but cultivation on nutritional media remains the gold standard in microbiological diagnostics. Choice of medium depends on the conditions in which bacteria were early and is present. The nature life determines its physiological peculiarity then a metabolic plasticity promote to survive and to save the virulence. In this review on the example of Yersihia pestis and Vibrio cholerae performed evaluations of the efficient decisions for the bacterial media development. It is declared advantage of baker's yeast hydrolisate as the nutrition media base.

Pneumocystis colitis in a patient with the acquired immunodeficiency syndrome.

We report a case of colonic pneumocystosis in a human immunodeficiency virus (HIV)-positive homosexual male who presented with fever and diarrhea. Stool cultures for bacterial pathogens and examinations for ova and parasites were negative. The diagnosis was made by colonoscopic biopsy which revealed Pneumocystis carinii organisms in the lamina propria of the cecum, descending colon, and sigmoid colon. The patient subsequently developed pulmonary and ocular abnormalities consistent with P. carinii involvement of these organs. The diarrhea and other manifestations resolved with antipneumocystis therapy. Many sites of extrapulmonary pneumocystosis have been reported, but we believe this is the first report of colonic P. carinii found in the evaluation of persistent diarrhea in a patient with the acquired immunodeficiency syndrome.
