Resumo: | A bacteriological study was conducted on fish and water from Congonhas River, Sertaneja (22º58’ S; 50º58’ W), Paraná State, Brazil. From 44% of the analysed fish, bacteria belonging to Pseudomonas, Acinetobacter, Aeromonas, Enterobacteriaceae, Micrococcus, Bacillus and Lactobacillus were isolated. The group most frequently isolated from fish was Aeromonas. In the water, the bacterial groups detected were Pseudomonas, Acinetobacter, Aeromonas, Enterobacteriaceae, Bacillus and Flavobacterium, from which Flavobacterium and Acinetobacter were the most abundant. The numbers of Colony Forming Units per millilitre of water varied from 3.1x10² to 1.0 x 10³. Although a clear pattern was not detected in the susceptibilities/resistances of the isolated strains to nine antimicrobial substances, Gram negative aerobic bacteria were more resistant than the other strains. A simultaneous resistance to furazolidone, oxolinic acid and norfloxacin, particularly in the bacteria isolated from fish, as well as in the aerobic strains isolated from water was observed. The antimicrobial substances to which less resistances were found were oxytetracycline in the strains isolated from water, and trimethoprim-sulphamethoxazole, oxytetracycline and chloramphenicol in those isolated from fish.
