Resumo

Background: Streptococcus suis is an emerging micro-organism responsible for causing meningitis, septicemia, arthritis, endocarditis and pneumonia, in addition to being an occupational zoonosis. In healthy pigs S. suis is located asymptomatically in the tonsils and may be disseminators sources pigs susceptible to the pathogen. To reduce these losses it is necessary to have effective control and treatment agent, however, it is known that antimicrobial resistance is a risk point for the success of the therapy. Thus, the aim of this study was to determine the resistance profile and the minimum inhibitory concentration of antimicrobial isolates of Streptococcus suis type 2 from tonsils of pigs at slaughter.Materials, Methods & Results: Tonsil samples from 302 slaughtered pigs were from three slaughterhouses, they were isolated and typified 219 S. suis type 2. The antibiogram was performed using the technique of Disk Diffusion and Agar 209 isolates in the following antimicrobials were tested: amoxicillin (10 µg), ampicillin (10 mcg), ceftiofur (30 mcg), ciprofloxacin (5 µg), doxycycline (30 mcg), enrofloxacin (5 mcg), erythromycin (15 µg), florfenicol (30 mcg), norfloxacin (10 µg), penicillin G (10 U) and tetracycline (30 µg). And 117 isolates were subjected to minimum inhibitory concentration (MIC), the following concentrations amoxicillin...(AU)
