서부 경남지역 토마토 농장에서 분리된 Staphylococcus aureus의내독소 유전자의 특성과 항생제 감수성

Abstract

To provide microbial information for the safety of agricultural production, the presence of enterotoxin genesand antibiotic susceptibility of 14 isolated Staphylococcus aureus (11.7%) strains were investigated using PCR-basedmethods and disk diffusion method, respectively. Among enterotoxin-encoding genes, sea was detected from two isolates(14.3%), sea and sed genes were co-detected from three isolates (21.4%), and sea, sed, and see genes in seven isolates(50.0%), whereas seb, sec, and tsst were not detected in any isolate. Nine (64.3%), eight (57.1%), six (42.9%), two(14.3%), and one (7.2%) isolates were resistant to penicillin, novobiocin, amphicillin, erythromycin and oxacillin, anddoxycycline and kanamycin, respectively. Methicilline-resistant S. aureus was found in roller of B farm and in hydroponicsolution of D farm.
