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

Introduction: Chemical methods of control: Antimicrobial drugs‚ involves the use of chemicals to prevent and treat infectious diseases. Pasteur and others observed that infecting an animal with Pseudomonas aeruginosa protected the animal against Bacillus anthracis. Later‚ the word “antibiosis” (against life) for this inhibition and called the inhibiting substance “Antibiotic”. As researchers found out more and more about these chemicals they were able to discover that antibiotics are chemicals

HOST FACTORS FOR SUSCEPTIBILITY It is not every individual exposed to the Mycobacterium tuberculosis that gets infected with the infection. Susceptibility to disease after infection by Mycobacterium tuberculosis is influenced by environmental and host factors (nature and nurture) A primary infection may heal‚ the host acquiring immunity in the process while in other cases‚ the primary infection may progress to produce extensive disease locally‚ or infection may be promulgated or disseminated to
