Salmonella is very serious when it is contacted and can be deadly, so make sure you follow proper hygiene to ensure that you are getting any bacteria off of your food and hands. Salmonella is also the leading cause of food poisoning in the United States. 2. How is this infectious agent transmitted through food or water? Salmonella can be contacted by usually eating or drinking something
Cystic fibrosis is a disease that causes the body to make thick, sticky mucus. This causes problems in two major parts of the body, the lungs and the digestive system. Healthy lungs produce mucus, which protects the airways and makes it easier to breathe. But for a person with cystic fibrosis, the mucus is thick and sticky and can clog up the lungs. This creates a place where bacteria can easily grow, causing infections.
They also feed on many Bacteria in decaying matter organisms to survive. Parasites are organisms that attach themselves to a host to infect, reproduce or spread diseases that it would be carrying. (2) Common illnesses and infections caused by Bacteria, Viruses, Fungi and parasites would be as follows. Bacteria which is present in food for example can cause Food Poisoning, Salmonella, Botulism, and other internal infections of the Stomach. Typical Viruses are illnesses like smallpox, measles, mumps and tuberculosis etc which can be contracted by touch or being within an environment that has the virus in the air.
CU254 Causes and spread of infection. 1.1/2 Bacteria There are 3 types of Bacteria cocci, bacilli or vibrio, and spirilla or spirochetes. Bacteria is found in everything the only place they aren’t found is where humans have sterilised. They can cause illnesses like tuberculosis, tonsillitis, and laryngitis and food poisoning Virus Virus is a toxin or poison. It is a microscopic organism consisting of genetic material.
It begins at the site of a break in the skin (a surgical or non-surgical wound). In order for someone to contract necrotizing fasciitis, the bacteria must be introduced into the body. Group A Strep is the same bacterium that causes strep throat This group of bacteria is responsible for mild cases of sore throat (pharyngitis), skin infections, as well as rare, severe illnesses such as toxic shock syndrome and necrotizing fasciitis. However, there are various strains of the bacteria, some of which are more powerful than others. With the right set of conditions, necrotizing fasciitis is a real risk and can cause severe damage.
All wounds, even minor cuts and scrapes, should be treated as contaminated and potentially serious and should be carefully cleaned to prevent infection. Some wounds, like in this case a bite, always carry a high risk of infection, especially because the wound contained imbedded foreign material (the tooth of the fish). This wound should have been left open to drain and medical consultation should have followed immediately; these wounds require antibiotic therapy and careful follow-up. Yet, an infection would still occurred, whether the tooth of the fish was in the wound or not, because of the bacteria that gotten into the wound and because the wound was not treated properly.

Giardia lamblia is a single celled organism that causes a diarrheal infection of the small intestines and is one of the most common parasites in the United States. Giardia lamblia is a flagellated protozoan parasite which means it is an organism with one or more whip-like organelles called flagella. Flagellum is a hair like appendage that protrudes from the cell body, and it is how the organism moves around. The infectious agent can be transmitted by ingesting or swallowing water, food, or soil that is contaminated with giardia cysts (hard shells containing giardia). Some examples would be public swimming pools or spas.
lung cancer. Communicable Diseases Communicable diseases are diseases that is carried by micro-organisms and spread through various objects and creatures e.g. animals, food, air etc. These diseases rely on the exchange of fluids contaminated substances, or close contact to travel from an infected carrier to a healthy individual. People frequently catch them and it can be caught very quickly and easily, but people also see that the time it takes to recover from these illnesses is also quick and easy.
Scientific Principles Bacteria Transmission Of a Bacteria Through Air As we exhale bodily fluids, through things like coughing and sneezing. This puts people around the infected area, in danger of catching the bacteria; this is because of its airborne properties. Through Contact This is the most common way that bacteria can be spread; there are bacteria everywhere around us and so if we are to be in contact with day to day things we are in danger of catching bacteria which could be good or bad. Through Poor Hygiene If there is a poor hygiene in a certain area, it will be more likely that the area will be high in bacteria compared to somewhere of high hygiene, where there is a high standard of cleanliness. Lifecycle Of a Bacteria The lifecycle of a bacteria consists of 4 phases which are the lag phase, the long or exponential, the stationary phase and the death phase.
Bad Bug Book Handbook of Foodborne Pathogenic Microorganisms and Natural Toxins Introduction Food safety is a complex issue that has an impact on all segments of society, from the general public to government, industry, and academia. The second edition of the Bad Bug Book, published by the Center for Food Safety and Applied Nutrition, of the Food and Drug Administration (FDA), U.S. Department of Health and Human Services, provides current information about the major known agents that cause foodborne illness. The information provided in this handbook is abbreviated and general in nature, and is intended for practical use. It is not intended to be a comprehensive
