Introduction‚ this bacterium is one that is not usually pathogenic‚ and occurs naturally in the human intestinal tract. E. Coli also happens to naturally occur in other vertebrates as well. This bacteria is very beneficial when naturally occurring‚ as it helps produce vitamins and breaks down foods (Tortora). However‚ there are eight or more strains of E. Coli that are pathogenic‚ and can cause serious damage. The most common side effect of a pathogenic strain of is diarrhea‚ according to the FDA. These

NOSOCOMIAL INFECTIONS Nosocomial Infection is an infection that occurs in a hospital of hospital-like setting. Approximately 10% of American hospital patients contract this infection. There are three factors as to why nosocomial infection exists: 1. A high prevalence of pathogens. 2. A high prevalence of compromised hosts. 3. Efficient mechanisms of transmission from patient to patient. These three factors alone lead not just to a higher chance of transmission

Subsets of this category are solid waste management‚ water and wastewater treatment‚ industrial waste treatment and noise and pollution control. Sanitation - is the hygienic means of preventing human contact from the hazards of wastes to promote health. Food - Any nutritious substance that people

Overall‚ Sambucus nigra liquid extract 3.2% inhibited the growth of influenza A and B viruses and bacteria that infect the upper respiratory tract. The researchers concluded that the Rubini elderberry extract is effective against both bacteria and Influenza types A and B viruses. For our experiment‚ we will work with Sambucus nigra and T cells. It will be interesting to see the effect of Sambucus nigra on T cells because

The world is exist with germs of all kinds especially viruses and bacteria. Most of the time human bodies do a wonderful job of fending off these microbes. This sort of self-defense is due to the immune system‚ which detects any pathogen also known as disease-causing agent and attacks it with immune foot soldiers including macrophages‚ lymphocytes and phagocytes. Specifically‚ over 700 different strains of bacteria have been discovered in the human mouth‚ though most people are only host to 34 to

Shigellosis is not susceptible to first line antibiotics so physicians must look for stronger defenses to fight this bacteria such. “Susceptible to ampicillin‚ trimethoprim‚ sulfamethoxazole‚ naldixic acid‚ ofloxacin‚ chloramphenicol‚ fluoroquinolones‚ and ciprofloxacin.” (1) These antibiotics are able to break through the outer shell of the bacteria to actually to kill it. Since some Shigella infections can become drug resistant it is best to not take antibiotics unless the infection
