Recently, cases caused by Campylobacter spp. in Russia similar to other countries tended to clearly rise, partly due to the widely implemented biomolecular PCR-based laboratory analysis that substantially facilitated Campylobacter spp. detection in patients samples. The problem of being infected by Campylobacter spp. is so far worth studying because of campilbacteriosis signs in a form of a variety of clinical patterns including local and general forms, possible trigger role in forming the consequent chronic digestive tract pathology as well as general systemic pathology. Development of colitis or heamocolitis as the pattern part of acute diarrhea caused by Campylobacter spp. is usually considered as associated with the disease burden. So far as adult patients have acute diarrhea with positive Campylobacter spp. samples it might be of interest to compare and analyze their clinical and laboratory data to find some possible associations as particular features of different disease patterns. Objective to analyze clinical features and laboratory data of hospitalized AD adult cases with feces samples positive for Campylobacter spp. When carrying out the retrospective cohort study the analyzed were clinical and laboratory data of 111 hospitalized adult patients suffering from moderate acute diarrhea with clinical samples (feces) positive for Campylobacter spp. To verify acute infectious diarrhea all patients went through complex specific laboratory examination that included PCR based methods (feces) with use of Amplisense AD screen-FL in addition to routine standard culture (feces), serologic (specific antibody detection) and ELISA laboratory methods. The analysis results have shown that more than 1/2 part of patients developed colitis syndrome with blood in feces in practically every forth case. In patients (predominantly males) without chronic digestive tract problems relative risks to develop colitis and haemocolitis are respectively 1.6 and 2.6 times higher given they are hospitalized on day 4 after the onset and later versus those hospitalized earlier.
