Detection and characterization of Salmonella spp. in recreational aquatic environments in the Northeast of Argentina

Detecção e caracterização de Salmonella spp. em ambientes aquáticos para uso recreativo no Nordeste da Argentina

Abstracts

The aim of this work was to detect the presence of Salmonella spp. in recreational aquatic environments in the Northeast of Argentina and to relate it with water and environmental parameters. Sixty eight samples of water from recreational aquatic environments in the provinces of Chaco and Corrientes, Argentina, were studied. Salmonellae were detected in 6 samples (8.8%). Salmonella spp. isolates belonged to the following species and serovars: S. enterica serovar Give, S. enterica subespecie IV, S. enterica ser. Bredeney, S. enterica ser. Rubislaw, and S. enterica ser. Enteritidis (two isolates). None of the isolates were resistant to tested antimicrobials. There were no significant differences among sampling sites as a reservoir of bacteria Salmonella spp. and the other variables. The presence of Salmonella spp. in our recreational aquatic environments reaffirms the need for monitoring in order to minimize the risks of infection to exposed persons.

O objetivo deste trabalho foi detectar a presença de Salmonella spp. em ambientes aquáticos para uso recreativo no Nordeste da Argentina e relacioná-la com parâmetros ambientais e das águas. Foram estudados sessenta e oito amostras de água de ambientes aquáticos de lazer nas províncias de Chaco e Corrientes, Argentina. Salmonella spp. foi detectada em seis amostras (8,8%). Salmonella spp. isolados pertenciam às espécies e sorovares S. enterica ser. Give, S. enterica subespécie IV, S. enterica ser. Bredeney, S. enterica ser. Rubislaw e S. enterica ser. Enteritidis (dois isolados). Nenhum dos isolados testados foram resistentes aos antimicrobianos. Não existiam diferenças significativas entre os isolamentos de Salmonella spp. e os locais de amostragem e o restante das variáveis. A presença de Salmonella spp. em nossos ambientes aquáticos para uso recreativo reafirma a necessidade de vigilância, a fim de minimizar os riscos de infecção das pessoas suscetíveis expostas.
