study of bacterial agents of intestine in infants under one year of age suffering gastroenteritis observed among the iraqi refugees residing at iran's western camps

one hundred and thirty specimens of faeces of infants under one year old suffering form gastroenteritis and residing at the camp of iraqi kurdish refugees (paveh and sar pol zahab cities) were collected and evaluated from the point of some bacterial agents. at the same time, some importantc1inical findings and environmental conditions were also collected for the study. the results showed that gastroenteritis mostly had a rapid incidence accompanied by fever, pain, straining, tenesmus and mucus-containing faeces. from a total number of 130 specimens collected, 10% proteus, 18%pseudomollas, 10% aeromonas, 1 % serratia, 1 % enteropathogenic e. coli, 4% klebsiella, 2% shigella, and 3% yersinia were isolated. antibiotic sensitivity test indicated a severe resistance of opportunistic pathogens against two antibiotics, i.e., chloramphenicol and co-trimoxazole which were mostly isolated in sar-polzahab camp. we can link this to prophylaxis with these two antibiotics the result of which is the augmentation of normal flora and its change to pathogens. the studies have shown that there is a significant relation between the camp's living conditions, nutrition, public health and isolated microbes.
