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.
