The aim is to assess the state of intestinal microbiocenosis in HIV-infected children at different stages of the disease.

Materials and methods: intestinal microbiocenosis was studied by quantitative bacteriological method in 85 HIV-infected children aged 242 months. Stage 2 b of HIV infection was reported in 45 (52.9%), stage 2 In 19 (22.4%) children, stage 3 in 13 (15.3%), stage 4 in 8 (9.4%). All children received antiretroviral therapy.

Results: children under 2 B stage of HIV infection with a high content of bifidobacteria, lactobacilli, enterococci has high frequency and levels of the vegetated bacteria of the genus Klebsiella (37.3%; 8 (6; 9) lg CFU/g) Escherichia coli hly+ (35.3%; 7 (5; 8) lg CFU/g) Staphylococcus aureus (29.4%; 5 (3; 6) lg CFU/g), S. epidermidis (15.7%; 5 (3; 6) lg CFU/g), the fungi of the genus Candida (58.9%; 5 (3; 6) lg CFU/g). At stage 2 V, the population level of bifidobacteria decreased to 7 (6; 8) lg CFU/g, the frequency of colonization by Candida increased by 1.5 times, which reached an average concentration of 6 (5; 8) lg CFU/g. In children with stage 3 HIV infection has registered an increase of 2 lg of quantitative levels of bifidobacteria, reduced to 30.8 % detection frequency of Candida, the average was 3 (2; 4) lg CFU/g. Klebsiella spp. and E. coli lac-were found in 30.8% and 23.1% of individuals, respectively. In stage 4 of HIV infection, the frequency of bifidobacteria and lactobacilli was 87.5%, the titers were below the age norms by 1-2 lg. 2 times increased frequency of colonization of mucosa by E. coli hly+, in 4 times with Candida.

Conclusion: changes in intestinal microbiocenosis are specific at each stage of HIV infection, which should be taken into correcting.
