dc.description.abstractThis study investigated the prevalence and plasmid profiles of βeta-lactamase positive Staphylococcus aureus isolated from the nasal and hand swabs of some healthy food handlers in Tanke area of Ilorin, Nigeria. Sensitivity test of the isolated strains of Staphylococcus aureus was carried out with six different types of penicillin based antibiotics using standard procedures. The plasmid profile was carried out using Agarose gel electrophoresis and the result shown in Polaroid gel instant camera through an orange filter. The photograph was develop and observed for bands. There was 100 % occurrence of S. aureus from both nasal and hand swab samples. The result reveals 31.57% βeta-lactamase positive Staphylococcus aureus (βPSA) from the nasal swabs, while it was 15.78% from the hand swabs. The strains of Staphylococcus aureus isolated from the nose and hand swabs were resistant to most of the selected penicillin based antibiotics in the following decreasing order: Penicillin (100 %), Ampicillin (86.84 %), Amoxicillin (73.68 %), Ampicloxacillin (68.42 %), Gentamycin (34.02%) and Erythromycin (15.78%). The results of plasmid profiles of the βeta-lactamase positive Staphylococcus aureus (βPSA) strains showed that 15.7% had distinct plasmid bands. Although, less than half of the total isolated Staphylococcus aureus strains were βPSA (23.6%) and 66.6% of the total βPSA carried distinct plasmid bands; which is an indication of a potential microbiological hazards in foods prepared by the food handlers especially, if proper hygienic condition is not maintained during food preparations.en_US
