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

Abstract

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

Assessment of Biocidal Efficacy of Zinc Oxide-Zeolite Nanocompoites as a Novel Water Disinfectant against Commercial Disinfectants Used in Water Purification

“…E. coli isolation in the screened water samples was not in consistent to those found by Selim et al [42], (8.0%) and Barbosa et al [43], (16.5%) also, Momtaz et al [44] , who found that only 4 out of 448 water samples (0.89%) were positive for E. coli. While, our findings for Salmonellae isolates were not matched to those isolated by Yam et al [45], (18.0%), Haley et al [46] (79.2%), Adingra et al [47] (15.4%), Momtaz et al ( [44] (7.58%), Tracogna et al [48] (8.8%), Yhils and Bassey [49] (12.9%) and Abd El-Tawab et al [50] (25.0%). Furthermore, P. aeruginosa was found in 38.9% and A. hydrophila wasn't detected in any of the examined water samples as reported by Mohammed [51].…”

Brote de Salmonella enterica subsp. enterica serovar Give asociado con enfermedad transmitida por alimentos en Vichada, Colombia, 2015

“…Generalmente, las sardinas enlatadas se han relacionado con contaminantes no biológicos (22)(23)(24), por lo que este es el primer reporte de contaminación de un producto enlatado por S. Give en el país, lo que se relacionó directamente con su estado de conservación, pues se evidenciaron filtraciones y abolladuras en el empaque y, dado que el lugar de producción no estaba protegido frente a la entrada de contaminantes físicos (aire, agua, polvo) ni biológicos (silvestres y domésticos), es posible inferir que la contaminación de la lata de sardinas por S. Give provenía del contacto directo con alguna especie animal infectada (no identificada), o que actuó como vehículo de contaminación ambiental, lo cual concuerda con la asociación ya establecida de S. Give con animales y ambientes acuáticos (3,4,6,7,(25)(26)(27)(28)(29).…”
