Leprosy: transmission, pathogenesis and clinical features

Biology /

What is Leprosy? Leprosy, also known as Hansen’s disease, is a chronic infectious disease caused by the bacterium Mycobacterium leprae. It primarily affects the skin, peripheral nerves, upper respiratory tract, eyes, and testicles. While once feared and stigmatized, it is curable with multidrug therapy. Transmission It is spread through prolonged close contact with an untreated person

Streptomycin gradient plate technique: Principle, Procedure, Observations and Result

Streptomycin gradient plate technique: Principle, Procedure, Observations and Result

Botany /

Streptomycin gradient plate technique The streptomycin gradient plate technique is a powerful tool used in microbiology to determine the minimum inhibitory concentration (MIC) of an antibiotic, streptomycin in this case, against a specific bacterial strain. This technique allows us to understand the susceptibility or resistance of bacteria to the antibiotic, providing valuable information for clinical diagnosis and

Leishmaniasis: Visceral (kala-azar), Cutaneous, Lupoid and Mucocutaneous

Biology /

Leishmaniasis is a group of infectious diseases caused by protozoan parasites belonging to the genus Leishmania. These parasites are transmitted to humans through the bite of infected sandflies. The disease manifests in various forms, each with distinct clinical features and severity: Visceral Leishmaniasis (Kala-azar) The Most Severe Form: It, commonly known as kala-azar, is the most serious

Dental caries susceptibility tests Snyder test

Dental caries susceptibility tests: Snyder test

Biology /

The Snyder test, a simple and inexpensive microbiological assay, provides a measure of an individual’s susceptibility to dental caries (tooth decay). It relies on the principle that the presence of specific bacteria in the oral cavity, particularly lactobacilli, is a strong indicator of the potential for caries development. These bacteria ferment sugars, producing acids that erode
