☠ Deadly Diseases ☠ Yersinia Pestis: Black Death Epidemic The 13th Century was home to the Black Death epidemic‚ also known as Y. Pestis. The most common form of Y. Pestis is the Bubonic Plague‚ however‚ there are two other form of the virus. This form of Yersinia Pestis wasn’t very contagious‚ and can only be caught by pus being introduced to a person’s open wound. The second form of Y. Pestis was the septicemic plague‚ spread by the most well known outbreak‚ coming from rats’ blood‚ then consumed

General information: What is E.coli? Escherichia coli‚ or commonly referred to as E.coli is a foodborne pathogen that normally inhabits in the intestinal track of humans and animals. It is the most common and wide spread infecting organism and is in the family‚ Enterobacteriaceae. Enterobacteriaceae is a large family of Gram-negative bacteria‚ meaning the bacteria appear pinkish or red. How fast and how does it spread? The main way that E.coli can spread is through food and water supply. Common

ignoring already published observations. Thus‚ three main tracks are followed for validation of the curative properties of guava leaves: a) the anti-microbial capacity…confirming its growth-inhibiting effect particularly on Staphylococcus aureus‚ Escherichia coli‚ and other common entero-pathogenic cultures; (b) the anti-diarrheic measured as an effect on motility property of intestine; and (c) the sedative effect of some guava extracts measured in animals on locomotor and nervous activity” (20).

Doyle and Schoeni (1984) reported 37 0C as the optimum temperature for growth of Escherichia coli 0157:H7 in Trypticase Soy Broth. This grew poorly in the temperature range of 44 to 45.5 °C which is generally used for recovery of E. coli from foods. Bettelheim (1998) designed Rainbow Agar O157 for the isolation and identification of EHEC. In this medium E. coli O157 was characterised by black colonies whereas O113 and some other EHEC strains were mauve‚ red or pink and indistinguishable from other

developing drought and herbicide resistant crops. Through genetic engineering‚ scientists have been able to introduce traits into existing genes to make crops resistant to drought and herbicides. One good example is the use of Bacillus Thuringiensis‚ commonly known as Bt. Bacillus Thuringiensis‚ is a bacterium that dwells in soil. It acts as a reservoir “of cry toxins and cry genes for production of biological insecticides and insect-resistant genetically modified crops.” How has gene technology benefited

Emergency Preparedness and Response Protecting the public’s health historically has been a state and local responsibility. However‚ the growing threat of bioterrorism has highlighted the importance of a strong public health infrastructure to the nation’s homeland security and has focused increased attention on the preparedness of the public health system (Frist‚ 2011). Since the 2001 anthrax attacks Congress has passed new legislation to increase the strength of the nation’s public health system

Silver sulfadiazine has numerous clinical advantages‚ including a broad antimicrobial spectrum and low toxicity. Silver sulfadiazine has in vitro activity against many burn wound pathogens including Pseudomonas aeruginosa‚ Staphylococcus aureus‚ Escherichia coli‚ Klebsiella‚ Proterus‚ Enterobacteriaceae and Candida albicans. The frequency of resistance development with silver sulfadiazine is considerably lower than with other antimicrobials. So in the majority of burn patients the drug of preference

Whooping Cough A. Name the bacteria that cause this childhood disease. What is its morphology? bacillus bordetella pertussis. B. pertussis is an extremely small‚ strictly aerobic‚ Gram negative‚ cocobacillus short rod. What does “Wooping Cough” mean? Pertussis is a highly contagious bacterial disease that causes uncontrollable‚ violent coughing. The coughing can make it hard to breathe. A deep "whooping" sound is often heard when the patient tries to take a breath. Describe in detail the

INTRODUCTION a) Background of the Study Ever since man utilized various species of plants for food‚ clothing‚ as medicines‚ fibers and other useful things. In fact‚ the interaction of man and the plants led to the establishment of the so-called traditional knowledge. One should look into the potential impact of the plant which are generally rich sources of many natural products‚ and its ecological environment and the manner on how it could be utilized for significant use for human welfare
