Abstract

This study was conducted to determine the occurrence and antimicrobial resistance of Salmonella serotypes isolates from feces, feed and broiler litter in poultry broilers in western Paraná between 2006 and 2010. The antigenic characterization and identification of serotypes confirmed 118 samples of Salmonella spp., belonging to 38 different serotypes. The most common serotypes identified were S. enteritidis (16.1%), S. heidelberg (5.9%), S. typhimurium (5.9%), S. hadar (5.0%), S. albany (4.2%), S. enterica (4.2) and S. saintpaul (4.2%). The serotypes of Salmonella spp. isolates were examined for resistance against 13 antibiotics using the disc diffusion method. Thirty-six samples (30.5%) were susceptible to all antimicrobials, and among the 82 resistant strains, there were 25 different resistance patterns. Serotypes’ multi-resistant to streptomycin, nalidixic acid and tetracycline (20.7%), nalidixic acid (13.4%) and nalidixic acid and tetracycline (11.0%) were found at higher frequency. The results revealed high prevalence of Salmonella spp. mainly S. enteritidis (16.1%) in aviary environment and percentage of strains’ resistant to conventional antibiotics.

Key words: Salmonella enteritidis, broilers, antimicrobial susceptibility, poultry.
