Streptococcus agalactiae was isolated from cultured tilapia in Brasil. All isolates reacted similarly in API 20 STREP system (bioMerieux, France) and Slidex strepto grouping Latex Aglutination test (bioMerieux, France). Bacterial isolates were submitted to the disc diffusion technique for the antimicrobial susceptibility test. Among nine tested drugs S. agalactiae samples were resistant to three-neomicin, nalidixic acid and gentamicin.
