Gastroenteritis is a wide spread disease, it is one ofthe major causes of morbidity and mortality in Egypt andother developing countries. Enteritis appear among the tenleading causes of death for age up to two years.Gastroenteritis was studied in this work from the differenta~ects ; as regards age, sex, locality, type of feeding,wheather breast, artificial, or combined and weaned group.We studied 400 cases of different age & sex. 229 casesof them (57.25%) from the rural area., & 171 cases (42.75%)from urban area. They were 252 males (63%) & 148 females(37%), their age varied up to two years.Stool samples or rectal swabs were examined to detect themost common bacterial species involved in the pathogenesisof gastro-enteritis. Pathogenic organisms were isolated from361 t9l.25%), cases only while 39 cases giving no growth(9.75%). The isolated pathogens were E. coli from 153 cases(38.25%), shigella from 56 cases (14%), Klesiella from 45cases (11.25%), Proteus from 43 cases (10.75%), staph. aureusfrom 21 cases (5.25%), Salmonella 12 cases (3%), Ps. pyocyanaeusfrom 15 cases (3.75%), Campylobacter (5 cases, 1.25%).& Candida 11 cases (2.75%).The incidence of gastroenteritis is more in the ruralarea than urban area., also the incidence in male was morethan females.Infection was predominant in infants above 6 months ofage. Enteropathogenic E. coli was the most frequent cause ofdiarrhea and it was more common during the first year of age,.below age of 6 months neither Shigella, Klebsiella, Salmonellaand campylobacter were encountered.According to seasonal variation it was noted that E.coli, Shigella, Proteus, Klebsiella mostly occured in the hotseason while staphylococcus, Candida mostly occured in thecold weather.The significance of seasonality in diarrhea cannot beignored as it is one of the factors determ’ining rural poverty.According to the type of feeding whether breast, artificialfeeding, combined feeding, weaned group were examined47 cases breast fed ones (11.7%), & 105 cases (artificiallyfed 26.25%) & combined feeding 126 cases (31.5%), whereweaned group were 122 with percentage 30.5% it is clear thatthe high incidence was in the last three groups as Bottlefed infants.
