COMPARATIVE ANALYSIS OF ANTIMICROBIAL STRENGTH OF THREE MOST COMMON ANTIBIOTICS

ABSTRACT

In comparing the antimicrobial strength of three most common antibiotics, which includes: streptomycin chloranphenicol and gentarccin. Samples of urine and high vaginal swab (H.V.S) were collected from park lane Enugu. The organisms isolated were pure culture of staphylococcus aureus and Escherichia coli. Sensitivity test was carried out with  the use of sensitivity disk containing various minimum inhibitory concentration of the different antibiotics. The result obtained shaved that gentamicn was more effective followed by chloramphenicol while some organisms shaved resistant to streptomycin.

CHAPTER ONE

INTRODUCTION

1.1     BACKGROUND OF THES STUDY

Antibiotics are chemicals when the chemical are put into the body; they stop the growth of kinds of germs. They help the body to fight diseases. More than 3,000 years ago ancient people stumbled over the discovery that some moulds could be used as a cure. The egyptians, the chinese, and indians of central American would use mold to treat rashes and infected would. At that time they didn’t understand either diseases or treatment. As time went on, people began to gain some insight of disease. In the 1860 Louis Pasteur Shaw that many disease were caused it bacteria. Later he discovered that we may be able to fight germ and other microbes. It was two German doctors, who were first to make an effective medication form microbes.

Kudo and Emmerich and Oscar has conducted their experiment in the  1890. They proved that germ that would for another. All the men did was to take the germ from infected bandages and grow then in a test tube. They would  then isolate a particular germ that caused green in factions in open would. This germs was bacteria called Bacillus pyoicyaneus. They put then into another test tube containing other type of bacteria, it was  then it happened that the bacillus pyocyaneus wiped out the other disease germ. The germs that was killed were those that caused cholera, typhoid, diphtheria and anthrau. From this the two men created a medication that they called pyoanase, it was the first antibiotics used in hospitals.
