Antigenic Detection of Salmonella Infection among Pediatric Patients with Acute Gastroenteritis

Background: Diarrheal diseases are one of the social problems in developing countries. The pathogens commonly associated with childhood diarrhea are Salmonella, Clostridium difficile, Shigella, Yersinia and Escherichia coli but the highest attack rate for salmonellosis in infancy. Objective: The aim of the study was to evaluate the presence of Salmonella antigen in acute gastroenteritis in children admitted to a pediatric hospital. Material and Methods: The study was performed on freshly collected stool samples among 94 acute diarrheal children below two years admitted to AL-Khadymia and AL-Elweya pediatric hospitals from May 2015 to January 2016. A questionnaire was completed for each patient's name, age, gender, clinical data like fever, nausea, vomiting, and abdominal pain. The criteria included hemorrhagic fresh stool sample in addition to containing parasite agent. Fresh stool samples were tested by immunochromatographic assay for antigenic detection of Salmonella. Results: Salmonella antigen identified in five stool samples one for male and four for females. All pediatric patients show fever, vomiting and abdominal pain, while the stool consistency distributed to 75.5% watery and 24.5% loosely. Stool samples show 69.1% with blood and 39.9% without blood, 16.9% with pus and 83.1% without pus, 83% with mucous and 17% without mucous. Four cases with giardiasis and 24 cases with entamebiasis and 14 cases with cyst of E. histolytica or G. lamblia in addition to absence the parasites ova in all stool samples. Conclusion: Salmonella antigen present in five stool samples, all the patients show vomiting, fever, abdominal pain, 65 cases with blood in comparison with, 29 without blood 15 cases with pus in comparison with 79 without pus. 78 cases with mucous in comparison with, 16 without mucous, four cases with goddesses and 24 cases with entamebiasis, 14 cases with cyst of E. histolytica or G. lamblia in addition to absence the parasites ova in all stool samples.
