Questions: A.What is a differential stain? How is it different from a simple stain? 1.A differential stain is a stain that differentiates between gram-positive and gram-negative bacteria. Bacteria that stain purple are considered gram-positive and those that stain pink are considered gram-negative. 2.A simple stain is a stain that reacts with all microbes in and…

Bacillus cereus is a Gram-positive, facultative aerobic, spore-forming, rod-shaped bacterium that is widely distributed among the environment. Introduction The reason for identification of unknown bacteria was to help students recognize different bacteria through different biochemical tests and characteristics. This is important in the medical field because identification of unknown bacteria can help treat a patient…

Tuberculosis ( TB ) is the taking cause of decease in the universe from a bacterial infective disease. The disease affects 1. 8 billion people/year which is equal to tierce of the full universe population. In the United States TB is on the diminution. In 2007 a sum of 13. 293 instances were reported. The…

The optical microscope has been a standard tool in life science as well as material science for more than one and a half centuries now. The optical microscope widely use in the field of cell biology, microbiology, biotechnology, pharmacology, forensic and medical diagnosis especially when dealing with tissue fragments. It is a type of microscope…

Introduction to Golgi Apparatus Discovered by “Camillo Golgi” in 1898 during investigation of nervous system. Works as an independent organelle. Golgi apparatus is present in eukaryotic cells as one or more groups of flattened, membrane-bounded compartments or sacs. Golgi apparatus is responsible for the processing and packaging of protein and lipids. The cisternae stack has…

Biosynthesis of Silver nanoparticles utilizing Red algaePortieria hornemannii Abstraction Nanotechnology is regarded as one of the most wanted Fieldss of research in the present scientific universe. The applications of nanoparticles scopes from pharmaceuticals, Even though the synthesis of nano atoms can be done by agencies of physical, chemical and green methods, owing to the eco…

Enterococci are bacteria that are included in the intestinal flora of humans and are relatively harmless. One method Enterococci maintain a symbiotic relationship is by hydrolyzing esculin in the presence of bile (Susan L. Fraser, 2012). However Enterococci are in the top three-nosocomial infections. When infected, enterococci can cause numerous infections such as urinary tract…

It is very critical in microbiology to determine the effectiveness of a chemical to either inhibit or kill an organism as it can help cure a disease. If the agent kills the bacteria, it is called bactericidal. If the agent inhibits the growth of bacteria, it is called bateriostatic. (Fundaments of Microbiology Lab Manual) The…

Introduction This work of identification of bacterium was performed through different biochemical tests. Unknown cultures were streaked on EMB, SS and MacConkey agar plates to distinguish the lactose and lactose non-0feremnetros and to identify the grams nature of the culture. The culture was also streaked on TSI agar slants to confirm the cultures ability to…
