Ascaris lumbricoides: Morphology, life cycle, Pathogenesis, lab diagnosis and Treatment

Biology /

What is Ascaris lumbricoides? Ascaris lumbricoides is a type of roundworm that lives in the human intestine. It is one of the most common worms that infect people, especially in places with poor sanitation and hygiene. The disease caused by this worm is called ascariasis. It mostly affects children and can lead to a range […]

Preparation of bacterial smear

Preparation of bacterial smear

Biology /

A bacterial smear is a thin layer of bacteria placed on a microscope slide for staining and examination. This technique is vital because most bacteria are transparent and require staining to be visible under a microscope. Proper smear preparation ensures that bacteria retain their shape and arrangement, allowing for accurate observation. Materials Needed for Bacterial

Starch hydrolysis test objectives, introduction, requirements and procedure

Starch hydrolysis test: objectives, introduction, requirements and procedure

Biology /

The starch hydrolysis test is a straightforward microbiological method used to identify if bacteria can break down starch, a complex carbohydrate, into simpler sugars. This ability is due to the presence of an enzyme called amylase. Bacteria that produce amylase can digest starch into smaller sugar molecules, such as glucose and maltose. This test is

Southern Blotting principle, procedure and application

Southern Blotting: principle, procedure and application

Biology /

What is mean by Southern Blotting? Southern blotting is a widely-used laboratory technique for detecting specific DNA sequences within a sample. First introduced by biologist Edwin Southern in 1975, it has become a key method in molecular biology to study genes, detect mutations, and perform DNA fingerprinting. The technique enables researchers to pinpoint a particular

Mycoplasma: habitat, morphology, culture and biochemical characteristics

Biology /

Mycoplasma is a unique group of bacteria known for its small size and unusual characteristics, often associated with diseases in humans and animals. Despite its simplicity, Mycoplasma’s biology is quite interesting. Let’s explore its habitat, morphology, culture, and biochemical features in clear terms.Mycoplasma is also called Pleuropneumonia-Like Organisms (PPLO) because they were first discovered in
