RESUMO

The prevalence of bacterial, parasitic and viral pathogens in infantile patients with diarrhea in community from July/2006 to March/2007 in Ouro Preto, Minas Gerais state, was determinated using routine bacteriology and serotyping assay techniques. Bacterial pathogens isolated from patients were, in decreasing frequency: diarrheogenic Escherichia coli serotypes and Salmonella sp. Enteropathogenic Escherichia coli (EPEC) was the most frequent (76%) pathogen isolated, followed by Enteroinvasive E. coli (EIEC) (44%) and Enterohemorrhagic E. coli (EHEC) (12%). Parasitc examination of diarrheic samples resulted in 24% positives to Giardia sp. Morever Rotavirus (18%) was also detected . Chi-square test and Fischers Exact Test were used to compare differences between the tests and control groups. A p-value of <0.005 was considered to be significant. Antimicrobial resistance was observed among some E. coli serotypes isolated from clinical samples. Previously, in Ouro Preto city, it has been done a study about the microbiology water quality, at the same community. The results of the present study from clinical samples were similar to this previously study, regarding the ethiological agents and antibiothic resistence profile. The socioeconomic factors, house quality, latrine ownership, type of water source were correlated with water use. Implications of these simple household water correlated with water sources and more deficient sanitary facilities for potencial water borne disease transmition were briefly discussed. Finaly, it could be concluded that data obtained from community-based study correlated with the high degree of contamination of drinking water in households previously studied will enable the justification of Ouro Preto to plan relevant studies on diarrhea and other diseases transmitted by contaminated water route.
