The aim of investigation to study the of some clinico-microbiological characterisrics of mixed intestinal infections in children of early age. Material and methods -the children under the age of 3 (infants and children), hospitalized in the Children's Clinical Hospitals № 1 and 7 in Baku for the 2019 year have been examined. Bacteriological and serological studies were carried out to diagnose intestinal infections on the day of admission to hospital feces of sick children were take as material for analyses. Totally the 117 children have been observed. To convirm the diagnosis of bacterial intestinal infection feces were cultured with subsequent detection of sensitivity to antibiotics and for viral intestinal infection, immunochromatografic test was used. The bacteriological and serological investigations were arried out in the Scientific-Research Institute of Medical Prophylaxis named after V. Y. Akhundov during 2019 year. Results -As a result of our studies, 33,3% (39) of children had mixed infection: a combination of viruses, particularly rotaviruses with St.aureus, E.Coli and C.albicans. From observing children 25 were under 6 month (21,4%), 15 -7-12 month (12,8%), 77 -1-3 years (65,8%). The combination of rotaviruses with other viruses (adenovirus and astrovrus) were the most frequently observed ones (5,1±2,0% and 6,8±2,3% accordingly) (p=0,167; p=0,067). Among opportunistic microbes the S.albicans was a leader. (In 18 (15,4%) patients). C.albicans was with rotavirus (p=0,063), in 5 (4,3±1,9%) with St.aureus and rotavirus (p=0,118) and in 4 (3,4±1,7%) with rotavirus and E.Coli (p=0,056). The viral intestinal infection with 2 associates occured in 5 (4,3±1,9%) of patientsrotavirus + St.aureus + C.albicans and rotavirus + E.Coli + C.albicans (p=0,056).

The purpose of this study was to study the state of the intestinal microflora in young children who received inpatient treatment for acute intestinal infections. A study of the microflora in 183 children aged 0 months. up to 3 years of life. 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%). As a result of studying the composition of the intestinal microflora in patients hospitalized with intestinal infection, a decrease in the number of E. coli and B. bifidum was found, 43.7% and 63.4%, respectively.

Among the leading risk factors for the development of emergency conditions in acute intestinal infections, especially in infants, some authors point to rickets, anemia, and abnormal antenatal pathology. The aim is to determine the frequency of occurrence of various risk factors for the development of emergency situations in tender-age infants. Materials and methods: 338 tender-age infants with urgent conditions were under observation. The study involved clinical-anamnestic, bacteriological, and serological methods. The aggravating factors were as follows: diseases of parents in 16 (6.2%), related marriages - 20 (7.7%) pregnancy pathology-137 (52.9%), prematurity-16 (6.2%), artificial feeding - 127 (49.0%), early diseases (acute respiratory viral infections, pneumonia, encephalopathy, intestinal infections). Results: According to the results of the study, the central nervous system damage was most often observed in children from 1 month to 6 months (80.2%), anemia was more detected in children of 1-3 years - 56.4%, rickets was more diagnosed in children aged 6-12 months -38.2%.
