Antimicrobial Susceptibility Testing (AST) & Antibiogram

CLASSES OF ANTIBIOTICS

There are several classification/types of antibiotics today, which is based on bacterial spectrum of activity (whether broad or narrow) or type of activity exhibited by the agent (whether bactericidal or bacteriostatic). Some antibiotics are also classified based on their chemical structure. And this leaves antibiotics within a particular structural class to have similar patterns of […]

SOURCES OF ANTIBIOTICS

Before the advent of conventional medicine used in clinical medicine today for the treatment of infectious diseases, people in ancient times and even now have been using some herbal plants traditionally for centuries to combat microbes that cause diseases in man. Recently, scientists have studied and reported results that support the use of these herbal

BRIEF HISTORY OF ANTIBIOTICS

Antibiotic history dates back to 1928 when Sir Alexander Fleming discovered the antibacterial effects of the yeast, Penicillium notatum, a Fungus in his laboratory. The “antibiotic era” was ushered in through the work of several pioneering scientists including Sir Alexander Fleming, Howard Florey, Ernest chain, Selman Waksman, Albert Schatz, Paul Ehrlich to mention but a

DEFINITION OF AN ANTIBIOTIC

There is no consensus to the definition of antibiotics. But it is very important that we do not displace the key points (“Killing and Inhibition”) that must be contained in any definition of an antibiotic. Abinitio, an antibiotic was originally defined as a substance produced by one microorganism, which inhibits the growth of other microorganisms.

Introduction to Antibiotic Resistance

In recent times, antibiotic resistance of pathogens to drugs (antibiotics) directed towards the degrading properties of microbes in vivo has been on the increase both in the community and in the hospital. Antibiotics are exceptionally vital in clinical medicine for the treatment of bacterial related infections, but unfortunately bacteria are capable of developing resistance to
