FREIJE, JA et al. Aislamiento de Salmonella spp. a partir de huevos de gallina para consumo comercializados en la ciudad de Casilda, Santa Fe, Argentina. FAVE, Secc. Cienc. vet. [online]. 2019, vol.18, n.1, pp.23-25. ISSN 2362-5589.

In order to determine the presence of Salmonella spp. in eggs from Casilda city, Santa Fe, Argentina, a total of 125 eggs were collected from different stores and yolks and egg shells were sampled. Both samples were seeded in tetrathionate broth with the addition of iodine and brilliant green solution and incubated at 43 ° C for 24 hours. An aliquot of the surface was taken from each medium seeded and seeded on Xylose-Lysine-Deoxycholate agar, being incubated for 24-48 hours at 37 ° C. The developed colonies were identified using biochemical tests and those identified as Salmonella spp. they were serotyped. Three strains of Salmonella spp. were isolated: Salmonella ser. Tiphymurium and Salmonella ser. Anatum from samples of yolk and Salmonella ser. Anatum from the egg shell of a third egg. The isolation of Salmonella spp. in eggs for human consumption reinforces the need to take biosecurity measures to reduce the incidence of this bacterium in the farms.
