Toxin gene profiles, genetic diversity, antimicrobial resistance, and coagulase type of Staphylococcus aureus from cream‐filled bakery products
We determined the toxin gene profile, toxin production, antibiotic resistance coagulase serotype, and genetic diversity of 42 coagulase‐positive Staphylococcus aureus (CPS) isolates collected from 1,464 cream‐filled bakery products in Korea. Among the CPS isolates, 37 (88.1%) produced enterotoxin ge...

description | We determined the toxin gene profile, toxin production, antibiotic resistance coagulase serotype, and genetic diversity of 42 coagulase‐positive Staphylococcus aureus (CPS) isolates collected from 1,464 cream‐filled bakery products in Korea. Among the CPS isolates, 37 (88.1%) produced enterotoxin genes in combination with another toxin; 26 (61.9%) of the strains were positive for sea, 1 (2.4%) for sea‐seb, and 4 (9.5%) for sea‐sec. Among the strains showing antibiotic resistance, 28 (66.7%) showed resistance to only one antibiotic, whereas nine (21.4%) showed resistance to multiple antibiotics: 4 (9.5%) strains were both mecA‐positive and oxacillin‐resistant. Most strains are resistant to at least one antibiotic—benzyl penicillin. The CPS isolates were classified into eight coagulase serotypes. This information will be valuable for assessing the capability risks of CPS food poisoning, contributing a better known of the epidemiology result associated with CPS contamination in bakery products. |
