    aureus is a gram-positive bacterium, which is a facultative anaerobe. It colonizes the skin, nostrils, and/or perineum (Thomer et al., 2015). This bacterium is an opportunistic pathogen that causes both short and long term illnesses after it invades the host. Some of these illnesses are bacteremia, toxic shock syndrome, sepsis, and endocarditis (Wang & Muir, 2016). Approximately one-third of the human population is colonized by S. aureus, and another one-third is intermittently colonized with…

    aeruginosa is frequently found in the hospital environment and in the normal stool flora, it is difficult to trace the source of infection and/or colonization unless a complete study is undertaken.(Teplitz et al., 1964). The epidemiology of hospital infections due to Pseudomonas aeruginosa was investigated by pyocin typing. The typing method, which determined the pyocin activity of clinical isolates of P. aeruginosa on 27 indicator strains, was 43.7% reproducible, but elimination of 9 indicator…

    There are many factors that have the potential to influence the emergence of new infections. A common factor is the spillover event. In the case of this event a pathogen present in one reservoir population will spread the pathogen to a new host or reservoir. An example of this is animal to human contact. For example, Ebola is thought to have been transmitted to humans by a bat. Meaning that the bat was the first reservoir host and passed it to a human host, a new population. Additionally,…

    pertussis gets into the respiratory tract, it attaches itself to the cilia of the epithelial cells of the respiratory tract. After doing this, the microbes release toxins that immobilize the cilia of the epithelial cells. One of the more understood pertussis toxins is called the lymphocytosis-promoting factor which is responsible for causing a decrease in the amount of neutrophils to the lungs making them susceptible to other bacterial infetions. It also leads to the inflammation of the…
