MICROBIOLOGY

Introduction: Cell locomotion may involve movement of the entire cell or a portion of it, to the benefit of the organism. This is a biological phenomenon displayed o enable many roles such as feeding, digestion, reproduction, circulation and protection. A cell’s or unicellular organism’s locomotion is accomplished by the use of flagella, cilia, and, in […]

Introduction: Bacteriophages are viruses that only infect bacteria which is also known as phages. They have a unique structural and life cycle and are highly abundant and diverse in nature such as water, soil, and the human body. It can infect and replicate within bacterial cells. The term “bacteriophage” originates from the Greek words “bacterio,”

Introduction: A virus is a microscopic infectious agent that can cause diseases which is able to utilize the synthetic machinery of the living cell of another organism for its multiplication. Virus are the smallest living organism ranging from about 20nm to 300nm that are about 50 times smaller than bacteria approximately.  They are too small

Background: Gram staining is a key technique in microbiology that allows bacteria to be classified into two groups: Gram-positive and Gram-negative. This staining method, developed by Hans Christian Gram in the late 1800s, gives vital insights into bacterial cell wall composition and has become a cornerstone of bacterial identification and classification. The differential staining is

Introduction: Bacteria are single-celled microorganisms that belong to the domain Bacteria. They are one of the most abundant and diverse kinds of life on Earth, and can be found in a variety of habitats. These microscopic organisms have a distinct cellular structure and a remarkable ability for adaptation and survive in a variety of environments,

Cryopreservation is the method of preserving cells, tissues, or organs by freezing them at extremely low temperatures, often below -130°C, for long-term storage or future use. The goal of cryopreservation is to inhibit biological activity and metabolic reactions that can harm cells and tissues while preserving their viability and functionality after thawing.
