Bacteria use two main methods: one where they copy themselves, and another where they make new versions. Let’s break down these processes in simple terms.

Welcome to a comprehensive exploration of the General Characteristics of Viruses.
In this article, we will delve into the captivating realm of viruses, shedding light on their unique features, functions, and the profound impact they have on our world.

Gram staining method is used to differentiate two large groups of bacteria on the basis of their different cell wall constituents.

Methods of sterilization part 3 contains Pasteurization, Auto clave, Incineration and Hot air oven in detail which are Physical methods of sterilization.

From many decades, scientists have developed different types of physical, chemical and mechanical methods of sterilization to control microbial growth.

The scientific methods of sterilization has began just about 100 years ago.Louis Pasteur discovered that microbes might be the cause for the diseases.

EXTERNAL STRUCTURES OF BACTERIA are 1.Flagella, 2.imbriae/ Pili, 3.Glycocalyx/ Capsules, 4.Sheaths, 5.Prostheceae & stalks, 6.Cell wall.

Internal structures of Bacteria are 1.Cytoplasmic membrane 2.Intracellular membrane system 3.Cytoplasm 4.Cytoplasmic inclusions, vacuoles and Nucleoids.

Genus streptococcus pyogenes is a Gram-positive bacterium. The word “Strepto” means “Easily Twisted” where as “Coccus” means “Grain, Seed or Berry”.

Morphology of bacteria : Each bacterial cell measures about 1.25 – 2 µm in diameter & 2-10 µm in length. Cocci are about 0.5-2.5 µm in diameter.

In this Basics of bacteriology post we will learn about some Historical facts, General characteristics of bacteria and will compare them with plant kingdom.

When essential nutrients are deficient, certain gram-positive bacteria form specialized “Resting” cells which are known as Endospores.

This post is about two microbiologist whose discoveries cause the beginning of new era in the field of microbiology,They are Louis Pasteur & Robert Koch.

A Bacterial Culture Media is a solid or liquid mixture of chemicals that can support growth of microorganisms and contain a source of carbon and energy.

Genus Staphylococcus can grow in environments like high osmotic pressure and low moisture. They can survive in our nostrils, skin, axilla or perineum.

This post is prepared for benefit of the Microbiology students. This contains all the topics along with their most important and frequently asked questions.

ASO (Antistreptolysin O) Titre Blood test is advised to determine whether a previous streptococcal infection has caused any complications.
