Shapiro–Wilk test. Qualitative variables are presented in terms of absolute value and percentage. Differences between quantitative variables were verified using Student t-test or χ2 test for categorical RG 7204 variables. Accepted criteria for statistical significance is P < 0.05. Campylobacter

infections were diagnosed in 71 children (29 girls and 42 boys), which represented 5.28% of children among 1343 patients hospitalized because of vomiting or diarrhea in 2008–2010. In 2008, it accounted 2.99% of hospitalization, in 2009 – 6.84%, in 2010 – 6.25%. C. jejuni infection was diagnosed in 64 children (90.1%), C. coli in 4 children (5.6%) and Campylobacter species in 3 children (4.2%). In 22 children Campylobacter infection was accompanied by other gastrointestinal infections (enteropathogenic

strains of E. coli (EPEC) Enzalutamide in 10 children – 14.1%, Rotavirus in 11 children – 15.5%, Salmonella type C in 1 child – 1.4%). According to the age, none of co-existing infections differed in frequency ( Table I). Duration of hospitalization was from 2 to 26 days (mean 7.24 days). Main period of incidence occurred in the period between May and October. Among infants, Campylobacter infection was diagnosed in 29 cases (14 girls and 15 boys), which accounted for almost 41% of all Campylobacter bacterial infections. In the age group between 1 and 3 years of age Campylobacter infection was diagnosed in 45.1% of children (13 girls and 19 boys). In total, in the age group up to 3 years of age Campylobacter infection was diagnosed in 61 children (86% of all Campylobacter infections). In the group above 3-year-old Campylobacter bacterial infection was diagnosed in 14.1% of children. According to the age, at the initial stage of infection various clinical symptoms were observed, shown in Table II. In the group under 1 year of age (29 children), diarrhea developed in 82.7% of patients, including those 15 children

(51.7%) had diarrhea with blood. Among this group, in 5 children (17%) vomiting was the only symptom of Campylobacter infection. Fever occurred in 37.9% of patients (11 children). Additionally, in one child the upper respiratory tract infection was found. In the age group between 1- and 3-year-old (32 Orotidine 5′-phosphate decarboxylase children), diarrhea developed in all children (in 34.3% of cases it was diarrhea with blood). Vomiting was observed in 37.5% of children. Fever was the symptom which occurred in less than a half of the patients (43.7%). Upper respiratory tract infection was diagnosed in 37.5% of children. In this age group, abdominal pain was relatively rare (in 9.4% of children). Among children over 3-year-old (10 patients) diarrhea occurred in 90% of cases and only one child had stools with blood. Vomiting was observed in 50% of children, fever and abdominal pain occurred in 30% of cases. Respiratory tract infection occurred in 2 children.
