Objective To analysis the difference in enterotoxin production between methicillin-resistant Staphylococcus aureus (MRSA)and methicillin sensitive Staphylococcus aureus (MSSA)so as to provide a reference to evaluate their association with staphylococcus aureus food poisoning.
Methods Meta-analysis was used to evaluate the data extracted from published articles domestic and abroad relevant to comparative prevalence of the enterotoxin-producing isolates in MRSA and MSSA during 1992-2008.
Results A total of 7 articles were retrieved. The overall effect indicator RR (95%CI)was 2.18 (1.58-2.99). The prevalence of the enterotoxin-producing isolates in MRSA was 2.18 fold greater than in MSSA.
Conclusion The probability of enterotoxin production in MRSA was far more than in MSSA.
