Dr. Straube Biology 107 Monday 3, 2010 Case Study #3 Tony is suffering from a disease caused from the microorganism Salmonella Typhi. Salmonella Typhi is a bacterium that is strictly a human pathogen with currently 107 known strains of the bacteria. Salmonella Typhi is a facultative anaerobic, gram-negative enteric bacillus belonging to the Enterobacteriaceae family. This organism was originally isolated by the late Karl J. Erbeth in 1880. It is a multi-organ pathogen that inhabits

What is the infectious agent (pathogen) that causes this infectious disease? For example, the name of the bacteria, virus, or parasite. Gram-negative bacteria. Typhoid fever is cause by salmonella. Salmonella infections are zoonotic and can be transferred between humans and animals. This infection can survive outside a living body for weeks. A distinction is made between enteritis salmonella and horny/paratyphoid salmonella where the latter, because of a special virulence factor and a capsule protein

INTRODUCTION Infection remains the main cause of morbidity and mortality in man, particularly in developing areas where it is associated with poverty and overcrowding.In the developed world increasing prosperity, universal immunization and antibiotics have reduced the prevalence of infectious disease. However, antibiotic-resistant strains of microorganisms and diseases such as human immunodeficiency virus (HIV) infection, variant Creutzfeldt–Jakob disease ,avian influenza and severe acute respiratory

How to Save a Life: The discovery of the Germ Theory Scientists often develop new theories and ideas once previous postulates are shown to be inadequate. After numerous attempts to understand how germs spread, scientists still lacked a theory that explained the cause of diseases. The germ theory was instrumental in formulating an understanding of various diseases in order to protect the public from lethal epidemics. The development of the germ theory is credited to Dr. Robert Koch, Dr. Joseph

Disease and Evolution The human body has been plagued with diseases since the beginning of time—pathogens like viruses and bacteria have made us privy to Mother Nature. As humans evolve, so do the diseases we are susceptible to. Some diseases that were once rare have become common, others have disappeared and newer, more daunting ones have emerged. Many of these changes have taken place in the wake of important transformations in human civilizations and ecology. It is therefore feasible to propose

Infection control is very important to minimise cross infection of Micro-organisms. Many micro-organisms are good for us and are essential for life, such as bacteria in the intestine which helps break down food waste matter. However, when a micro-organism is capable of doing harm it is said to be pathogenic. There are four main micro -organisms that cause disease, these include, Viruses, Bacteria, Fungi, and Protozoa. Personal Protective Equipment (P.P.E) can act as a barrier to protect you against

Introduction Dietary fibres, also known as roughage, are a diverse group of the indigestible portion of the plant foods (i.e., cellulose, hemicellulose, lignin, pectin and beta-glucans) which are resistant to digestion in the small intestine and require bacterial fermentation located in the large intestine. These enables smooth bowel movement, prevent constipation, hemorrhoids, cardiovascular diseases (CVD), type 2 diabetes and diverticular disease. Dietary fibres contain combination of resistant

Generalized and Specialized Transduction There are several mechanisms in which bacteria transfer genes with one another. Vertical gene transfer is the transfer of genetic material during cell division. Horizontal gene transfer, on the other hand, is the transfer of genetic material between different species of bacteria; three types are found. Conjugation is the transfer of DNA by direct contact with the cell. Transformation is the uptake of genetic material from the surrounding. Transduction is
