Virulence and Antibiotic Resistance Genes in Strains Isolated From Ready-to-Eat Foods in Chile.

is causing listeriosis, a rare but severe foodborne infection. Listeriosis affects pregnant women, newborns, older adults, and immunocompromised individuals. Ready-to-eat (RTE) foods are the most common sources of transmission of the pathogen This study explored the virulence factors and antibiotic resistance in strains isolated from ready-to-eat (RTE) foods through and testing by whole-genome sequencing (WGS).

spp. are opportunistic pathogens of the family. The organism causes infections in all age groups, but the most serious cases occur in outbreaks related to neonates with meningitis and necrotizing enterocolitis.

[Carriage of Staphylococcus aureus among food service workers].

Background Staphylococcus aureus produces 11 serotypes of endotoxins that may cause food poisoning. Aim To determine the prevalence of type A enterotoxigenic Staphylococcus aureus carriage among food service workers in Chillan, Chile. Material and Methods Pharyngeal swabs were obtained from 100 food service workers and were cultured in Agar plates.
