ABSTRACT Antibacterial activity of medicnal plants has turned out to be a global concern. Medicnal plants are very useful in treating various diseases. Antibiotics are an important class of pharmacological agents used for treating antibacterial infections. Although antibiotics were first isolated from fungi and bacteria but over the years more and more synthetic antibiotics has been synthesized‚ which are in great demand. This present study has been done to determine the antibacterial activity of

The world is exist with germs of all kinds especially viruses and bacteria. Most of the time human bodies do a wonderful job of fending off these microbes. This sort of self-defense is due to the immune system‚ which detects any pathogen also known as disease-causing agent and attacks it with immune foot soldiers including macrophages‚ lymphocytes and phagocytes. Specifically‚ over 700 different strains of bacteria have been discovered in the human mouth‚ though most people are only host to 34 to

Lab Report: Antibiotic Evaluation by the Kirby-Bauer Method Introduction Chemical antimicrobial agents are chemical compounds capable of either inhibiting the growth of microorganisms or killing them outright. Those which are taken internally to alleviate the symptoms of or promote healing from disease are called chemotherapeutic drugs‚ and among these is a class of compounds called antibiotics. In order for a chemotherapeutic drug to be classed as an antibiotic‚ it must be produced by

Experiment 9: Growth curve of Serratia marcescens Abstract Bacteria grows by binary fission. The aim of this experiment is to follow the growth of Serratia marcescens in nutrient broth at 37oCby recording the changes in turbidity (cloudiness) by measuring the absorbance of visible light (600 nm) and also to prove that there is an increase in the cell number and not just in mass during the growth. In the experiment we measure the full growth curve of Serratia marcescens by measuring the absorbance
