| The fast agglutination screening test, using S. Typhimurium as the antigen, was compared with the standard bacterial method to identify rheas (Rhea americana) contaminated with Salmonella spp.at slaughter.Seventy birds were serologically tested for Salmonella enterica Pullorum using a commercial antigen.Of these, 66 were also submitted to a macroagglutination test, using a strain of Salmonella Typhimurium isolated from rheas.All birds did not react with the commercial S. Pullorum antigen, but 37 were positive for the FAST-ST.The isolation of Salmonella spp. was verified in 66 (94.2%) birds. 85.7% were found in liver samples, 60% in feces and 42.3% in cloacal swabs.A total of 16.6% were identified as being S. enterica enterica rugosa, 35.9% as S.... |

| The antimicrobial resistance of 96 Escherichia coli strains isolated from a stabilization pond system on a pig-breeding farm was evaluated. Strains were tested for their resistance against 14 antimicrobial using the agar diffusion method. E. coli strains showed resistance to tetracycline (82.3%), nalidixic acid (64%), ampicilin (41%), sulfamethoxazole/trimethoprin (36%), sulfonamide (34%), cloranphenicol (274%), ciprofloxacin (19%), cefaclor (16%), streptomicyn (7.3%), neomicyn (1%), amoxacilin/ clavulanic acid (1%), and amikacin (1%). No resistance was observed to gentamicin and tobramycin, and 37.5% of E. coli strains were resistant to four or more antimicrobials. The multiresistance pattern was found in strains isolated during all sampled period.... |
