Abstract

Abstract The global problem of antimicrobial resistance is particularly pressing in developing countries of which Nigeria is not left out. The aim of the study is to test the susceptibility or resistance of Staphylococcus species from milk samples to commonly used antibiotics. A total of 592 quarter milk samples, 30 bulk milk samples and 27 swab samples of the hands of milk men were examined from 12 dairy farms in Kaduna and Zaria. One hundred and three (103) Staphylococcal isolates that were Gram positive and catalase positive were identified biochemically, out of which the identities of 51 different Staphylococcal species were confirmed using the Microbact Microgen kit. From these, 30 selected isolates were tested against 9 commonly used antibiotics. The antibacterial sensitivity pattern of the 30 isolates to common antibiotics showed a complete (100%) resistance to Amoxicillin and a complete (100%) susceptibility to Ciprofloxacin, but the isolates showed varying degrees of resistance & susceptibility to the other antibacterial agents. All the isolates exhibited multiple antibiotic resistance to 3–6 antibiotics. Methicillin resistance was manifested in the resistance of the organisms to Cefoxintin (a surrogate of Methicillin).
