  • Fecal Coliforms

    Fecal Coliforms are a subdivision of the Coliform bacteria. Fecal Coliforms normally live in the gastrointestinal tract of mammals (warm blooded) including human. Fecal Coliforms do not live too long when they are outside the host. On the other hand, the Coliform bacteria are independent (living freely) and not attached to the digestive tract of man or animals. Also, they are not pathogenic (disease causing) organisms. Thus, these bacteria indicators are easy to identify and safe to work with in the laboratory and their presence provide an evidence of fecal contamination. The fecal category contains both pathogenic and nonpathogenic bacteria. For instance, Escherichia coli or E. coli is a fecal Coliform bacteria. Therefore, the presence of fecal Coliforms is an indicator of fecal contamination and of the potential presence of bacterial pathogens. However, “the intensity of other indicator bacteria (total Coliform, fecal Coliform, and fecal streptococci) is a degree of water safety for body contact recreation or for…

  • Colonial Life In Jamestown

    Salt and fecal coliform infected the drinking water. When the colonists drank the water, they got sick and many died. The infected water was used to grow crops, but instead decreased the plant growth. The water was also the home of fish, and the fish died. The plants and animals the colonists ate died, leaving small rations of food for the colonists to starve. Lastly, when the colonists attacked the Natives, the Natives wanted revenge. The Natives killed the colonists for revenge, and because…

  • Waterborne Diseases Research Paper

    cholerae, Shigella dysenteriae, and Salmonella typhi. The World Health Organization attributes the mortality of water associated diseases to over 5 million people a year, with 1.5 million of those deaths being children1. More than half of these deaths are caused by microbial infections, with cholera infections being the most common1. While generally considered rare in developed countries such as the US, waterborne diseases are extremely common in the developing world due to the lack of access to…

  • Norton Pond Case Study

    consistent, which will be classified as the most productive lake. Table 7, describes the population of nekton of each lake. This table shows the size and species of the collected nekton. It appeared that only Bluegill was tested out of Wakefield, and were the biggest in all species. The lack of diversity of fish on each lake, could be, from what the student think, an error with the fish retrieval prosses, or to be affected by the urban population around. After the prosses of incubation, all the…

  • Gram Negative Bacteria Lab Report

    life in the waters that help maintain the ecosystem. One of the quality standards include the Total Coliform Rule (TCR), which sets both a health goal and a maximum contaminant level goal (Environmental Protection Agency, 2013). TCR was enacted in 1989 to protect the health of the public, by monitoring and assessing the levels of the total amount of coliform present in the drinking water. Coliform bacteria are always present in the digestive tracts of warm blooded animals and is usually found…

  • E. Coli Bacteria

    coli is commonly found in the intestines of cattle and can become linked with meat if fecal matter from the animal’s intestines contaminates the meat during the butchering process². E. coli is then mixed into the hamburger meat during grinding and processing. Serious illness results from eating improperly cooked hamburger meat because cooking temperatures are cannot sufficiently kill the organism. Transmission of E. coli has also occurred when fecal matter of cattle contaminated fruits and…

  • Faecal Contamination Essay

    Faecal contamination of water is routinely detected by microbiological analysis. The approach that has been adopted is to analyses for indicator organisms that inhabit the gut in large numbers and are excreted in human faeces. The presence of these indicator organisms in water is evidence of faecal contamination and therefore, of a risk that pathogens are present. If indicator organisms are present in large numbers, the contamination is considered to be recent and/or severe. Total coliforms,…

  • Doggy Doodoo: Harmful To The Environment

    Salmonellosis, Cryptosporidiosis, Campylobacteriosis (Doody), E. Coli, and other bacteria and parasites that can harm humans (ACS). This shows that dog elimination has many harmful results if swept into the waterways. It gives people many painful and infectious diseases. Dog feces has dangerous effects when not deposited properly and can make humans sick. Dog feces has bacteria that is not healthy. This is a final way that not properly disposing of dog poop is dangerous. It can be harmful to…

  • Wastewater Pollution Essay

    alternative biological method for wastewater treatment. Phage bio control in large scale treatment requires adaptive and aggressive phages that are able to overcome the environmental forces that interfere with phage-host interactions while targeting unwanted bacterial pathogens and preventing bio films and foaming. This review will shed light on aspects of using Bacteriophages programming technology in wastewater plants to rapidly target and reduce undesirable bacteria without harming the useful…
