Abstract

Methicillin-resistance Staphylococcus aureus (MRSA) is an emerging veterinary and public health concern in both the human and animal populations. Livestock Associated MRSA (LA-MRSA) have been isolated in livestock and animal handlers. This study was aimed to determine the prevalence and antibiotic resistance profile of S. aureus and MRSA isolated from goats and animal handlers in Terengganu. Samples were collected from 140 goats, 5 veterinary personnel and 49 farm workers. Nasal swabs were collected from animals. Nasal and throat swabs were collected from veterinary personnel and farm workers. Identification of S. aureus and MRSA strains was phenotypically determined, and detection of nuc and mecA genes using PCR assay. All positive isolates were subjected to antibiotic susceptibility testing to 12 antibiotics. S. aureus was isolated from 42 (30%) goats and 18 (33%) veterinary personnel and farm workers. MRSA was only isolated from 1/6 (17%) nasal swab of human samples. The nasal isolates of S. aureus from goats showed high rates of resistance towards penicillin (81%), chloramphenicol (67%), and tetracycline (60%). The nasal isolates of S. aureus from human showed high rates of resistance to kanamycin (100%) and penicillin (83%), whereas the isolates from the oral swab showed high resistance to cefotaxime (100%), kanamycin (92%), chloramphenicol (58%), and penicillin (58%). This study provides useful information on MRSA in goats and human population in the study area and gives better understanding in the antibiotic-resistance pattern of the S. aureus isolates.
