Abstract

Microbiological aspects as to quality of estuarine waters of Jaguaribe River (Ceará State), and Curimataú and  Açu Rivers (Rio Grande do Norte State) were assessed by means of the estimation of fecal and total coliforms, vibrios and  salmonelas. The most coliform-infected sites were found to be points 5 and 7 at Jaguaribe River, points 1, 3, 6, 3 and  7 at Açu River and points 1, 3 and 4 at Curimatú River. Several serovars of  Salmonella enterica subsp. enterica were  detected in those estuaries. The Vibrio species isolated were  V. carchariae, V. alginolyticus and non-O1, non-O139  V.  cholerae , at Jaguaribe River; non-O1, non-O139  V. cholerae, V. alginolyticus and  V. parahaemolyticus , at Açu  River; and  V. parahaemolyticus, V. cholerae  non-O1, non-O139,  V. vulnificus, V. harveyi ,  V. alginolyticus and  V.  mimicus , at Curimataú River. The results of this research should be used as background information to health-oriented  policies through programs meant for sanitary education as a  first step towards establishing an ef fi cient system of basic  sanitation in the region.
