The presente study described the epidemiological and etiological aspects of acute diarrhea in Juruti, Pará, Brazil. A total of 261 fecal samples were investigated (diarrheagenic, n = 170 and control, n = 91), from patients attended in Public Health Units in the period from February to July 2009. Samples were investigated for bacterial, Rotavírus and parasitic enteropathogens using microscopic examination, immunological tests (ELISA) and bacterial culture techniques. Two multiplex PCR were designed for the detection of all categories of diarrheagenic Escherichia coli. A total of 154 samples were positive (diarrheagenic, n = 118 and control, n = 36), in which 75,4% were represented for mono infections and 24,6% for mixed infections. Most of cases included children less than 10 years of age (55,9%), which no significant difference were found between female and male. The most common enteropathogens in diarrhoeal samples were E. histolytica/E. dispar (26%), Shigella spp (15,7%), Giardia lamblia (13,3%) and diarrheagenic E. coli (12,8%), from which Shigella spp (p = 0,0028) were shown to be associated to the cases of acute diarrhea. The most frequent categories of E. coli in diarrhoeal cases were ETEC (7,2%) and EAEC (5,9%). The less frequent enteropathogens, in diarrhoeal samples were Campylobacter jejuni/coli (4,7%), Rotavírus (2,8%), Salmonella Panama, A. hydrophila and A. sóbria (0,5%). These results are useful for environmental and epidemiological surveillance of acute diarrhea disease in Juruti.
