more often than not a disease such as cholera is not a worry because of our clean water supplies and filtration equipment, while in developing third world countries, it is more often the water, and many symptom-less carriers pass large amounts of bacteria in their feces that further contaminate water supplies or transmit by poor hand washing. While Cholera is rarely spread directly from

the properties of individual particles. The Kingdom Monera is the most prominent. Examples of these are the bacteria. Bacteria are the first life forms. They are the smallest and the most numerous. They have no complex organelles and have only a few hundred genes. They grow, replicate DNA and split for every twenty minutes. Another example are the viruses which are much smaller than the bacteria and are not considered as living things. Next, the Kingdom Protista, from the name itself, are composed mainly

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 the

Kristal Martinez SCI163 September 26, 2012 Sally Fierro Salmonella Salmonella is the name for over 2,500 types of bacteria found in unwashed fruits and vegetables, uncooked or undercooked meats and eggs and contaminated water. Salmonella bacteria are capsule shaped that are known to cause diseases in humans, animals, and birds, especially poultry. Many of these bacteria can cause illness in humans, and they can pass from the feces of people or animals to through the foods processing or harvesting

very contagious if spread to others or objects are handled by a person who has the hepatitis A virus. The ways to be contaminated by this virus is by someone not washing hands after using the restroom. Or by changing diapers. It is caused by feces bacteria. Also Hepatitis A can be in contaminated water by seafood that we eat. We can also get it from using contaminated needles from either drug use or from hospitals. Very unlikely it would be from hospitals, as in they always use new needles that

The spores possess a though outer covering made of protein keratin which is resistant to staining. 2- Explain the terms sporulation and germination. Sporulation is the process of endospore formation within a vegetative cell; germination is the process of an endospore returning to its vegetative state. 3- List

hands before handling food, can transfer the poison. While cooking, it can be transferred by using the same cutting board or cooking utensils for raw and cooked meats. Not washing your hands while handling different types of food can transfer the bacteria as well. Contamination can come from animal or human feces during processing or harvesting. The soil in which some crops grow can be contaminated as well. Milk that hasn’t been pasteurized can contain salmonella. There are news reports all the

wastewater so that excessive oxygen consumption won't become a problem when it is released to the environment. (Maier et al, 2009) Another goal of biological treatment is nitrification/denitrification. Nitrification is an aerobic process in which bacteria e.g Nitrosomonas sp, Nitrobacter sp oxidize reduced forms of nitrogen. Denitrification is an anaerobic process by which oxidized forms of nitrogen are reduced to gaseous forms, which can then escape into the atmosphere. This is important because
