Fusidic acid is a bacteriostatic antimicrobial agent and/or antibiotic that is derived from the fungus, Fusidium coccineum. It is used as a topical antimicrobial agent to treat skin infections caused by pathogenic microbes including Staphylococcus aureus and Propionibacterium acne. Fusidic acid is an antibiotic that belongs to a group of antimicrobials known as the fusidanes.
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

Biology of Candida glabrata Candida glabrata is a fungus species of haploid yeast of the genus Candida, previously known as Torulopsis glabrata. Despite the fact that no sexual life cycle has been documented for this species, C. glabrata strains of both mating types are commonly found. Vaginal yeast infection, caused mainly by Candida albicans (and
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

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
