At the same time, 43 (23.5%) children received breast milk, 53 (29.0%) were artificially fed and 87 (47.5%) mixed-fed children. All children were examined by bacteriological method. Conditionally pathogenic flora among hospitalized patients was detected in 114 (62.3%), Candida was mainly detected in 67.5% of cases, in 57 patients (50.0%) in association with other opportunistic microorganisms — Candida + St. aureus — in 32 (28.1%), Candida + P. vulgaris — in 9 (7.9%), Candida + + P. vulgaris + St. aureus — in 12 (10.5%), Candida + St. aureus + Ps. aeroginosa — in 4 (3.5%).
