Introduction to Recombinant DNA (rDNA) Technology / Genetic Engineering

Recombinant DNA (rDNA) technology or genetic engineering is the in vitro controlled manipulation of nucleic acids (DNA and RNA) in order to produce new gene products or a combination of genes with improved biological function. It is an advanced and modern form of biotechnology. In genetic engineering, the genetic makeup of living organisms (especially microorganisms) […]

Introduction to Parasitology

DrChika

Parasitology is the study of parasites and their interaction with other organisms (i.e. their hosts). It is the study of parasites, their ecology, transmission and life cycle. The study of parasites is as ancient as mankind as man became conscious of his immediate environment. The field of Parasitology was fully established and widely appreciated in

PUBLIC HEALTH AND PARASITIC DISEASES

DrChika

Public health is a branch of medical sciences that primarily deals with the surveillance, control, detection and prevention of the emergence and spread of infectious diseases in a defined human population. It involves the protection and improvement of the health of the general public. In clinical medicine, doctors and nurses practice their profession by looking

STERILITY TESTS OF BIOLOGICAL PRODUCTS

DrChika

The phrase sterility simply means the absence of living organisms including bacteria, fungi, viruses, protozoa and other vegetative cells in a product. Sterility is usually achieved through the process of sterilization. And sterilization is defined as the process of by which objects, materials or environments can be rendered sterile (i.e. free from living organisms). Sterilization

Introduction to Pharmaceutical Microbiology

DrChika

Pharmaceutical microbiology is the branch of microbiology that focuses on all aspects of pharmacy especially as it relates to the manufacture and quality control of pharmaceuticals such as drugs, vaccines, and medical devices. It is an applied branch of microbiology that focuses on the study of microorganisms that are directly or indirectly involved in the

PHYSIOCHEMICAL ENVIRONMENTAL FACTORS THAT AFFECT CELL CULTURE

DrChika

Cell or tissue culture experimentations should not be carried out in the regular laboratory space where other laboratory investigations are undertaken. This is critical to avoid contamination of cells in the cell culture plates and also to ensure that all the physiochemical environmental factors that encourage optimal growth of the cells are provided. Thus, cell

Introduction to Cell Culture

DrChika

Cell culture is the laboratory technique of growing and maintaining the cells of multicellular organisms (plants and animal cells inclusive) in a favourable artificial environment conducive for growth. It is the maintenance of animal cells (inclusive of plant and human cell lines) in vitro.Such an artificial environment or growth medium mimics the internal environment of

BRIEF HISTORY OF EPIDEMIOLOGY

DrChika

The search for the ravaging scourge of some infectious diseases including cholera, typhoid fever, small pox and the rest, and an urgent need to end their prevailing end of human lives some decades ago gave impetus to the full development of epidemiology. Epidemiology as a field in the medical sciences and as an important discipline

Introduction to Epidemiology

DrChika

The word epidemiology was coined from three different Greek words: epi (upon or on), demos (population or people) and logos (study of). Epidemiology (which is the basic science of public health) therefore is defined as the field of medical science that studies the occurrence, distribution, and determinants of disease and health-related issues, and the application

Introduction to Microbiology of Oral Infection

DrChika

The first investigation into the world of oral bacteria was first made by the father of microbiology Anthony von Leeuwenhoek (1632-1723) – who was the first microbiologist to observe and describe microorganisms accurately. Leeuwenhoek observed his mouth washings under his amateur microscope and discovered small living creatures which he called animalcules. Leeuwenhoek opined in his
