IN VITRO DETERMINATION OF BACTERICIDAL EFFECT OF GARLIC ON STAPHYLOCOCCUS AUREUS

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.

CHAPTER ONE

1.0     INTRODUCTION

Allium satirum  commonly known as garlic is an odoriferous plant belonging to a family lilacease.  It is a small perennial herb with narrow flat leaves and surrounded by membranous patches, it is grown mostly in  Northern Nigeria. It is used primarily for seasoning or spice and also for its medicinal property.  The plant  contain a medicinal properly just like other plants such as aloes, Indian liquorices, alligator pepper etc which are also found useful, although the extend is not accurately recorded.  The medicinal property of garlic is due to its “sulphur” content which was believed to be responsible for it’s medicinal value.  Garlic as a medicinal plant has been widely used and found to be effective on number of serious infections.  Other plants like the ones mentioned earlier also have their medicinal properly, some which is as a result of the presence of ackloids, volatile oils, polyphenol and some related sulphur compound contained in them.  Similarly,  some are found to be used as  vermifuge, stimulating carminative toxic and also as condiments and for treatment of worm bites just like garlic.
