Cetrimide selective agar

Cetrimide selective agar is used for the selective cultivation and isolation of Pseudomonas aeruginosa isolates from clinical and non-clinical  samples. The preparation of cetrimide selective agar is elaborated in this section. P. aeruginosa is a pigment-producing bacterium. The organism produces certain types of pigments including pyocyanin (blue-green pigment), pyomelanin (black pigment) and pyoverdine (yellow-green and fluorescent pigment) [Figure […]

CAMP Test for Identification of Group B Streptococci

The CAMP test (named for the original authors: Christie, Atkins, and Munch-Petersen) was first used in the identification of group B streptococci (GBS). Group B streptococci secrete a protein called CAMP factor or “protein B” that interacts with the beta-hemolysin produced and secreted by Staphylococcus aureus, this results in enhanced or synergistic hemolysis. The CAMP

Anthroponotic Disease (Anthroponosis) & Sapronoses

An anthroponotic disease, or anthroponosis, is an infectious disease in which a disease causing agent carried by humans is transferred to other animals. It may cause the same disease or a different disease in other animals. The opposite of anthroponosis or anthroponotic  disease is zoonosis. Zoonosis is a disease transmitted from animals to humans. Zoonoses

PHARMACOKINETICS & PHARMACODYNAMICS

Pharmacokinetics is simply the study of how the body reacts to therapeutic agents or drugs over a period of time. It investigates what a therapeutic agent or drug does to the body after being administered. The pharmacokinetics of a particular drug describes alterations in the absorption, distribution, metabolism and the elimination or excretion of the

DRUG INTERACTION

To be clinically effective for the treatment of infectious diseases, every drug must reach a certain level of bioavailability in vivo; and this is critical because drugs contain other constituents aside the actual portion of the medicine which is necessary to express antimicrobial action in the recipient host. The bioavailability of a drug is the
