Microbiological evaluation of an acute gastroenteritis outbreak

Abstract

 Purpose: Acute gastroenteritis is one of the most important causes of morbidity and mortality especially in children. In water-borne outbreaks, more than one infectious agent may act as the cause of the disease due to contamination of water with feces.

Material and Methods: We evaluated 440 patients who applied to Şırnak State Hospital Emergency Service in two weeks. Their complaints were; vomiting, abdominal pain and diarrhea and were pre-diagnosed as gastroentiritis. Fresh stool samples were examined by native-lugol method for parasitological examination. For bacteriological examination stool samples were inoculated on Salmonella/Shigella agar and EMB agar. For Rotavirus, adenovirus and Entamoeba histolytica detection, rapid diagnostic assays were used. 

Results: We detected one or more intestinal parasites in 146 samples (33.2%). We identified 96 Entamoeba histolytica (21.8%) and 44 Blastocystis (10%), and we found   Giardia lamblia in 24 (5.5%) of them. 16 (3.6%) of the stool samples were positive for Rotavirus. In any of the samples neither adenovirus nor Salmonella nor Shigella spp. were detected.

Conclusions: The reason for this outbreak may be the pollution of drinking water with sewage water and lack of adequate water purification. In order to prevent such diseases the sterilization of the drinking water appropriately is very crucial.
