DISCUSSION/CONCLUSION: The first culture’s results were found with the help of the unknown chart, handed out by the instructor. The unknown tube, #125, was isolated in order to grow two separate cultures. However, a problem was faced after the isolation was incubated. The plate was contaminated and had more than two different bacterium’s growing. A second isolation was completed and when observed there were only two bacteria’s growing. After isolating one of the bacterium a Gram stain was performed

Ebola The 2014 Ebola was the largest epidemic virus in history, causing a colossal damage in the human body prolonging them to death. The notoriously deadly virus cause fearsome symptoms, the most prominent being high fever and massive internal bleeding. Ebola virus kills as many as 90 % of the people it infects. It is one of the viruses that is capable of causing hemorrhagic (bloody) fever. Ebola spreads through direct contact with bodily fluids. A cough from a sick person

Marburg disease is a very rare but severe hemorrhagic fever. It can affect either human or animals. Marburg HF is caused by Marburg virus, a genetically unique zoonotic (or, animal-borne) RNA virus of the filo virus family. The five species of Ebola virus are the only other known members of the filo virus family (Bausch DG, 2008). 31 people became ill after the first outbreak in laboratories of Marburg and Frankfort Germany in 1967. Reported death was total of seven. The first people infected had

Background Pseudomonas aeruginosa is an important cause of hospital acquired infection. It is frequently recovered species from clinical specimens and multidrug resistant P. aeruginosa are increasingly being reported worldwide. The important factor responsible for aminoglycoside resistance is Aminoglycoside modifying enzymes (AMEs), carried by mobile genetic elements. In spite of high resistance, aminoglycosides are still an important treatment option in infection with P. aeruginosa. Aim: The study

INTRODUCTION: Bloodborne pathogens are microorganisms that present in human blood and they can cause diseases. These pathogens include: – Viruses such as hepatitis B (HBV), hepatitis C (HCV) and human immunodeficiency virus (HIV), also, parasites such as malaria and certain fungi. Sharp-tools, needle-sticks and other apparatus-related injuries may expose stuff to bloodborne pathogens. To eliminate the risk of occupational exposure to bloodborne pathogens, implement an exposure control plan for workers

Following are the tests used for the identification of bacterial species based on the differences in the biochemical activities of different bacteria. Beta glucouronidase test is used for the identification of Escherichia coli. An enzyme is produced by E.coli which is beta D glucouronidase. Beta d glucouronidase in turn hydrolyzes beta d glucopyranosid uronic derivatives to aglycons and D glucuronic acid. Bile solubility test is used in laboratory for differentiation of alpha hemolytic Streptococci

The presence of bacteria and pathogenic organisms is a concern when considering the safety of drinking water. Pathogenic organisms can cause intestinal infections, dysentery, hepatitis, typhoid fever, cholera, and other illnesses. Sources of Bacteria in Drinking Water: The Need for Water Testing Human and animal wastes are a primary source of bacteria in water. These sources of bacterial contamination include runoff from feedlots, pastures, dog runs, and other land areas where animal wastes are deposited

Periodontal disease is characterized by a loss of the connective tissue attachment induced by the presence of the dental plaque. The loss of periodontal tissue progresses in the apical direction, thus affecting all periodontal tissues. The primary etiology of periodontal diseases is the presence and maturation of a bacterial biofilm eliciting a host response (Socransky & Haffajee 2005). More specifically, in the posterior teeth, many factors play their role in affecting the onset and development

Describe beneficial and harmful impacts of prokaryotes on human health and give some specific examples. Prokaryotes have both harmful and beneficial impacts on humans. Half of human diseases are caused by Prokaryotes while other prokaryotes serve as essential tools in agriculture and industry. The bacillus Mycobacterium tuberculosis causes lung disease tuberculosis and 2 to 3 million people die in a year. Another 2 million die from diarrhea caused by other prokaryotes. Lyme disease, caused by

A. Pathogenesis of Diarrhea 1. Virulence Factors a. Vibrio cholera 01 and some V. cholera non-01 produce enterotoxins also known as cholera toxins. Escherichia coli also produce Enterotoxins such as heat labile toxin and heat stable toxins. Enterotoxins such as these, act on the intestinal mucosa and cause abnormal net fluid secretion. Moreover, Clostridium perfringes, Bacillus cereus, and some strains of Salmonella typhimurium deem to have similar enterotoxins. Enterotoxin activity has been
