is not able to bind and the second dye is observed. Some known Gram-positive genera are Bacillus,…

INTRODUCTION There have been multiple staining techniques before the Gram stain came about in 1883. These old staining techniques brought about issues because they stained both the tissue and the cells so it was hard to differentiate between the two. Christian Gram is the inventor of the gram stain and found this technique when he was looking at Streptococcus pneumoniae in the lung tissue of people and animals (1). When working with these tissues, he found that this bacterium would take up a…

They investigated the synthesis of silver nanoparticles by the spore crystal mixture of Bacillus thuringiensis (Bt). Bt had been used because of its ease of availability and lack of seasonal dependence. The Bt strain IS1 was isolated from the soils of Bikaner, Rajasthan and was added to a mixture of silver nitrate to form silver nanoparticles…

a possibility. Contracting tuberculosis is simply that easy. Tuberculosis is an airborne contracted disease and in the 18th and 19th centuries, the infectious disease ran rampant throughout Europe and North America. Tuberculosis is caused by the bacillus mycobacterium tuberculosis, as well as mycobacterium bovis and mycobacterium…

HISTORY OF PREVELANCE: It is not clear when gas gangrene was officially discovered, although records from the Civil War indicate it was known at the time (Gillett, 1987, p. 280). Hospital gangrene was much more common than Gas Gangrene during the Civil War because it spread through direct contact (Gillett, 1987, p. 280). Gas gangrene was relatively uncommon during the Civil War, but became much more common in later wars such as World War I and World War II. In World War I, gas gangrene was the…

B Sridhar et al (2012) studied Purification and Characterization of Biosurfactants. The emulsifications of biosurfactants were checked in various oils such as olive, coconut, sunflower and rice bran oils, the emulsification activity of biosurfactants. Pseudomonas aeruginosa had higher emulsification activity than Saccharomyces cerevisiae. While checking the sugar and lipid content in biosurfactants by phenol sulphuric acid method and vanillin reagent method, found high in Pseudomonas aeruginosa…

definitively resolved back in 1930s with the isolation of swine influenza; a virus which when administered intranasally to susceptible swine induced a mild illness of short duration.2 The physician Richard Pfeiffer had created the hypothesis that Bacillus influenza (now Haemophilus influenzae) was the cause of influenza during the pandemic of 1892.3 The bacterial…

Materials and method Microorganisms are classified in to the three domains of life. The organism that is predominately found in our environment is bacteria closely followed by archaea and eukaryote. Although, microorganism might seem similar, they are different interims of their structures, biochemical composition, and the habitat they adopt. Conducting an extensive test on microorganism has many benefits. We can protect our self’s from different types of infectious disease. In the unknown…
