Chromosome Morphology
In 1848, Hofmeister discovered chromosomes (chroma: color; soma: body) as darkly stained bodies in the pollen mother cells of Tradescantia and they show high affinity to basic dyes. The chromosomes…
history of bacterial growth physiology
Abstract Arguably, microbial physiology started when Leeuwenhoek became fascinated by observing a Vorticella beating its cilia, my point being that almost any observation of microbes has a physiological component. With…

Microbiology Laboratory Safety Rules and Procedure
Safety in a microbiology laboratory is important in the prevention of infection as Microbiology laboratory cultures, manipulates, and uses virulent and/or potentially pathogenic microorganisms. In addition to microorganisms, there are…
Endospore Staining: Principle, Procedure and Results
When vegetative cells of certain bacteria such as Bacillus spp and Clostridium spp are subjected to environmental stresses such as nutrient deprivation, they produce metabolically inactive or dormant form-endospore. Formation of endospore circumvent the…
FLAGELLA STAIN
INTENDED USE Hardy Diagnostics Flagella Stain is recommended for use in detecting the presence and arrangement of flagella on the bacterial cell. SUMMARY Bacterial flagella, due to their narrow diameter,…
Acid-Fast Stain- Principle, Procedure, Interpretation and Examples
It is the differential staining techniques which was first developed by Ziehl and later on modified by Neelsen. So this method is also called Ziehl-Neelsen staining techniques. Neelsen in 1883 used Ziehl’s…
Gram Staining: Principle, Procedure and Results
