Aim: To reveal the pattern of microorganisms in chronic infective diarrhea cases.
Methods: We examined all patients suffering from chronic infective diarrhea over a six year period The patients were examined physically and at the same time laboratory tests,colon enema X-ray and colonoscopy, ileoscopy, upper GI endoscopy and small bowel X-ray were performed.
Results: We found 138 (66. 7%) chronic infective diarrhea from 207 chronic diarrhea patients. Parasitic causes were Candida albicans (48.55%), Blastocystis hominis (6.52%), Entamoeba histolytica (3.62%), and Giardia lamblia (3.62%) etc. Bacterial causes were Pathogenic E. coli(34.78%), Aerobacter aerogenes (3.62%), Mycobacterium tuberculosis (3.62%), Geotrichum (1.45%), Shigella sonnei(0. 72%), Salmonella paratyphi (2.89%)etc.
Conclusion: The most frequent microorganisms and parasites found in chronic infective diarrhea were pathogenic E.coli and Candida albicans.
