Mycoplasma: Structure, Habitat, Morphology, and Clinical Significance
Mycoplasma are the smallest known free-living organisms without a cell wall. They are unicellular, prokaryotic (Gram -ve), and independently replicating (i.e., they contain metabolic machinery to grow and multiply in the absence of other cells, thus showing autonomous growth).
Tobacco Mosaic Virus: History, Importance , Structure and Symptoms
Tobacco Mosaic Virus (TMV) is a plant virus that mainly infects tobacco plants but can also affect other crops, including tomatoes and peppers. It is a rod-shaped virus, one of the first ever discovered and studied.
Bacterial Culture Media: Definition, Composition and Classification
Bacterial Culture Media Bacterial culture media are nutrient-rich substances designed to support the growth, proliferation, and maintenance of bacterial populations in a controlled laboratory environment. One of the most important reasons for culturing bacteria in vitro is its utility in diagnosing infectious diseases. Isolating a bacterium from sites in the body normally known to be … Read more

Definition, Classification and Types of Microorganisms
Microbes or microorganisms are microscopic organisms (i.e., they are not visible to naked eye) that exist as unicellular, multicellular, or cell clusters. Microorganisms are widespread in nature (they make up almost 60% of the earth’s living matter) and are beneficial to life, but some can cause serious harm.
Microbiology: Definition, History and Importance of Microbiology
Microbiology is the study of organisms and agents that are too small to be visible with the unaided eye – that is, the study of microorganisms.
