Serotype characterization of Salmonella strains isolated from different affections in domestic animals.

摘要

The serotype characterization, antimicrobial susceptibility profile, and clinical epidemiological findings were evaluated in 53 Salmonella spp. strains isolated from 41 dogs, nine horses and three cattle presenting different clinical manifestations between 1997 at 2007. Salmonella Typhimurium (45.3%), Salmonella enterica (22.6%), Salmonella Enteritidis (7.5%), Salmonella enterica subsp. enterica 4,5,12i (5.7%), Salmonella Newport (5.7%), Salmonella Dublin (3.8%), Salmonella Agona (3.8%), Salmonella Glostrup (3.8%), Salmonella Saintpaul (1.8%) were the more common serotypes. Ciprofloxacin (100.0%), norfloxacin (100.0%) and gentamicin (100.0%) were more effective drugs while resistance of isolates was observed to ceftiofur (28.5%) and florfenicol (7.0%). The strains were isolated from animals with enteritis, urinary tract infections, septicaemia, pyometra, pneumonia and conjunctivits. The results showed the high frequency of Salmonella Typhimurium serotype in different animals studied. The study highlighted also the presence of serotypes in our animals that also have been identified in humans with salmonellosis.
