ABSTRACT

Invitro determination of bacteriocidal effect of garlic extract on staphylococcus aureus causing skin and urinary tract infection (UTI) on some female patients were studied.
High vagina swab (HVS) samples were collected randomly from selected number of patients who had symptoms similar to that of Staphylococcus aureus activities.  The samples were inoculated on Macconkey agar and nutrient agar and incubated at 370c for 24-48 hrs.  Colonies that appeared pinkish in whitish creamy and yellowish on nutrient agar were gram stained and examined microscopically. Also, biochemical tests were carried out in order to characterize the organism present in each positive sample 80% of the samples examined were found to react positively to Staphylococcal infections. It’s prevalence is more among the age range of  18 – 30 years.  It is suggested that government should encourage public health education on the potency of the cheap and readily available antibacterial agent like garlic and it’s addition to daily dietary which will act as a prop drug especially to women to reduce the incidence of S. Aureus  that causes skin and urinary tract injection.  Garlic extract has been proved to be an excellent cure to the ailment.
