This study aimed to help in searches related to the contamination of water bodies after dumping sewage rich in pathogenic bacteria Pseudomonas aeruginosa, Escherichia coli and Staphylococcus sp found in sewage hospital with clinical capability with the characteristic of multi-resistance to antibiotics becoming a health problem public and environmental. We collected 60 samples (20 samples to identify Pseudomonas aeruginosa, 20 for Staphylococcus sp. In 20 to identify Escherichia coli) in the sewage of the Red Cross Hospital - PR where the treatment is based on the addition of sodium hypochlorite as a means of disinfection, and this divided by 3 points: H1 (entrance of the sewage in the treatment system), H2 (output of sewage after going through the treatment system) and H3 (output of sewage after going through the treatment system with bottle collection of possessing tiussulfato sodium). For confirmation of the identification of the same species of pathogenic bacteria of the hospital until the body water, were held 36 samples (12 samples to identify Pseudomonas aeruginosa, 12 samples for Staphylococcus sp. In 12 samples for Escherichia coli) in the treatment system which uses the municipal Ralf as a form of treatment (SANEPAR Atuba-South) on points: S1 (entrance of the sewage in the treatment system) and S2 (output from the sewage treatment system for the Rio Atuba class 2) where the result was compared with Resolution CONAMA 357/05 which determines the parameters for eviction in accordance with the classification of the river. As a result of analysis of the sewage of the hospital was identified the presence of the bacterium Pseudomonas aeruginosa in 19 samples, 19 samples positive for Staphylococcus sp. And 13 samples confirmed the presence of Escherichia coli. In studies of SANEPAR were confirmed the presence of 11 samples of Pseudomonas aeruginosa, 12 tests positive for Staphylococcus sp. And 12 positive samples of the bacterium Escherichia coli. To the strains identified were performed 4 test of resistance using the discs for dissemination to Pseudomonas aeruginosa, amikacin, cephalothin, ceftazidime, gentamicin, imipinem, norfloxacin, sulfa-trimetoprim where in the hospital and in the system of municipal treatment and the antibiotic tetracycline were cephalothin more resistant to the bacteria Staphylococcus sp. Escherichia coli and the test of resistance were used discs for the dissemination of antibiotic amoxicillin, amikacin, ampicillin, cephalothin, ceftazidime, gentamicin, imipinem, norfloxacin, sulfa and tetracycline-trimetoprim. The result of the bacterium Staphylococcus sp. Was resistant in the hospital system and the network of treatment and the antibiotic amikacin tetracycline.
