Etiological Analysis of a Food Poisoning Caused by Staphylococcus Aureus

摘要

Objective To analyze the etiology of food poisoning,provide data support for food poisoning treatment,and protect people’s health.Methods RT-PCR was used to screen suspicious food and vomit.An enzyme-linked immunofluorescence assay(ELFA)was used to detect Staphylococcus aureus enterotoxin.RT-PCR was used to detect enterotoxin genotypes.An automatic drug sensitivity reading system was used for drug resistance analysis and mass spectrometry identification.Results Staphylococcus aureus were isolated from 5 leftovers and 2 vomitus samples.The enterotoxin types of 7 strains were sed and seen;the drug sensitivity test showed that 7 strains were resistant to penicillin,and 6 strains were inducible clindamycin resistant.Conclusion This is a food poisoning event caused by Staphylococcus aureus,which produces sed and sees enterotoxins.The isolated strains have different degrees of drug resistance.
