Amoeba proteus is one kind of amoeba, a single-celled creature included under the kingdom Protista . Its capacity to shift shape and amorphous morphology are mainly attributed to the existence of pseudopodia, which are transient cytoplasmic extensions that are used for feeding and mobility. Amoeba proteus is a species of amoeba that is primarily found […]
Alternaria alternata is a ubiquitous and opportunistic fungal pathogen known for its role in plant diseases, allergic reactions in humans, and potential mycotoxin production. It belongs to the genus Alternaria, which comprises several species notorious for their environmental resilience and ability to cause spoilage in a wide range of crops. After bacteria and yeasts have
Albert Staining is a special staining technique used primarily for the visualization of metachromatic granules (also known as volutin or Babes-Ernst granules) within bacterial cells, particularly in Corynebacterium diphtheriae. These granules are composed of polymetaphosphate and are characteristic of certain bacteria. Over time, certain stains have been created to help with species identification, morphological differentiation,

The Kinyoun Cold Method is a modified version of the traditional Ziehl-Neelsen acid-fast stain technique used for identifying acid-fast bacteria, particularly Mycobacterium species such as those causing tuberculosis and leprosy. This method, developed by Joseph Kinyoun, does not require heating (“cold” method), making it simpler and safer for routine laboratory use. Here’s an overview of

Active and Passive immunity are the two types of immunity .Active immunity is a form of immunity that develops when a person’s immune system responds to a foreign pathogen (such as bacteria, viruses, or other microorganisms) by producing antibodies and memory cells. Passive immunity is a form of immunity in which antibodies are transferred from
