Novobiocin susceptibility test Principle, Procedure and Results interpretations

Novobiocin susceptibility test: Principle, Procedure and Results interpretations

Biology /

Novobiocin susceptibility test is primarily used to distinguish between species of coagulase-negative staphylococci, specifically Staphylococcus saprophyticus, which is novobiocin-resistant, from other coagulase-negative staphylococci, such as Staphylococcus epidermidis, which is novobiocin-sensitive. Novobiocin susceptibility test Novobiocin susceptibility test is a diagnostic process used in microbiology laboratories to evaluate if a bacterium is susceptible (sensitive) or resistant to […]

Somaclonal variation: Basis, Applications and limitations

Biology /

Somaclonal variation, a fascinating phenomenon in plant tissue culture, refers to the genetic and phenotypic variations observed in plants regenerated from cultured cells or tissues. This inherent ability of plants to exhibit variability after a period in vitro (outside the living organism) presents a powerful tool for plant breeders and researchers. This comprehensive overview delves

Hematopoiesis: Types of Haematopoietic stem cells, Process and Regulation

Biology /

Hematopoiesis is the process by which all blood cells are produced from hematopoietic stem cells (HSCs) in the bone marrow. This process is vital for maintaining the proper function and balance of the blood and immune systems.

Tinea capitis: etiology, clinical manifestation, diagnosis and treatment

Biology /

Tinea capitis, often known as scalp ringworm, is a contagious fungal infection that affects the scalp, hair shafts, and occasionally the brows and eyelashes. It is caused by dermatophyte fungi, specifically Trichophyton and Microsporum species. These fungus feed on keratin, a protein found in hair, skin, and nails. Tinea capitis Tinea capitis, often known as
