Portación de Staphylococcus Aureus Enterotoxigénico Tipo A, en frotis nasofaríngeos en manipuladores de alimentos.

Resumen

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. After identifying the presence of Staphylococcus aureus, DNA was extracted to identify type A toxin by conventional PCR. Results: Thirty eight percent of samples were colonized with Staphylococcus aureus. Among these, 26% were toxin A producers. Conclusions: Half of the sampled workers carried Staphylococcus aureus and a quarter of these produced type A enterotoxin.
