Neisseria Obligate Human Pathogens

Improved Essays
Neisseria is a bacteria named after a German physician named Albert Neisser (Murray, Rosenthal, and Pfaller 312). This organism can be described as aerobic, gram-negative cocci that does not form endospores. In addition to these authors’ findings, the genus Neisseria contains 10 species found in humans (Murray et al. 312). Two specifically, Neisseria gonorrhoeae and Neisseria meningitidis, are obligate human pathogens that have been reported to cause opportunistic human infections (Hung, “The Biology of Neisseria Adhesins”). Due to this bacterium being obligate human pathogens, it means that in order for the disease to occur, they must transmit it from one host to another. N. gonorrhoeae is a sexually transmitted disease (STD) that is the most

    The genus Enterococcus was first distinguished in 1899 as a saprophytic coccus that held the capacity to cause infection and originated in the intestine (6). At the same time, researchers, W. MacCallum and T. Hastings defined a similar microbe from a case of endocarditis that would become known as Enterococcus faecalis (6). Enterococcus, a low class of lactic acid bacteria, was categorized as group D streptococci until 1984— it now consists of 37 different species (6, 7). Researchers were able to demonstrate that pre-existing species in genus Streptococcus were genetically closer to species in the genus Enterococcus than Streptococcus (6). In 1984, Streptococcus faecalis was redefined as Enterococcus faecalis (6, 7).…

    Moreover, M. Luteus found in soil, air, and it is part of the human skin flora. Also, M. lutes is known for its growth in dairy products which can be transmitted through consumption of milk [3]. Thus, the ideal environment for M.Luteus is aerobic habitat with 37 C temperature. M.luteus rarely causes infectious diseases in human, but it is an opportunistic pathogen for immunosuppressed patients, such as HIV patients [4].Thus, M.luteus is associated with different diseases which are recurrent bacteremia, meningitis, septic shock, septic arthritis, endocarditis, and cavitating pneumonia in immunosuppressed patients. Also, this bacteria is associated with urinary tract infections.…

    Introduction: Klebsiella pneumoniae is a part of the family Enterobacteriaceae. This genus is a gram negative and it has no flagella, which meant that this bacterium is not motile. However, it can move with the use of the current that is produced by the water. This bacterium has the ability to cause destructive change in a man or animals lungs if aspirated. In addition, this is also one of the most contacted pathogen in a Hospital Acquired Infection (HAI) or nosocomial infection.…

    In everyday life, people use disinfectants, substances used to destroy viruses and microbes such as bacteria and fungi1, to clean their bathrooms. If not properly sterilized and cleaned, the bathroom can be a domain for numerous bacteria including ubiquitous Serratia Marcescens, a short, rod shaped, facultative anaerobic, opportunistic pathogen that can cause nosocomial infections such as urinary tract infections, bacteraemia, meningitis, sepsis and cerebral abscesses2. Facultative anaerobic meaning that it can live and grow with or without molecular oxygen3. Serratia Marcescens is a gram negative bacterium. Gram negative bacteria have a thin cell of a single layer of peptidoglycan that is enclosed by an outer membrane.…

    Based on the laboratory tests provided, it can be determined that the unknown organism can be identified as Pseudomonas aeruginosa (P. aeruginosa). This organism is an opportunistic pathogen that can infect non-mammalian, plants, and humans. P. aeruginosa belongs to the bacterial family Pseudomonadaceae, and is a gram-negative rod that approximately measures 0.5 to 0.8 µm by 1.5 to 3.0 µm. It can normally be found in water and soil. Its single polar flagellum makes it motile, and it is known to be one of the fastest swimming bacteria found in hay infusion and pond water (Crittenden, Trussell, Hand, and Howe 2012).…

    Chlamydia is known as an infection that is caused by a type of bacteria that is passed during through sexual contact (Planned Parenthood 2014). It is the most common sexually transmitted bacterial infection in the United States. Statistics show that about 3 million American women and men are infected with chlamydia every year (Planned Parenthood 2014). Mostly it is common amongst women and men under the age of 25 (Planned Parenthood 2014). It is more than three times as common as gonorrhea and is fifty times as common as syphilis (Planned Parenthood 2014).…

    In 2013, more than 1.2 million Americans were diagnosed with a sexually transmitted disease by the name of Neisseria gonorrhoeae. Men and women between the ages of 13-64 receive this pathogen that is caused by oral and or anal sexually actions. The most common route for a pathogen to attach to the host would be through the respiratory or gastrointestinal tract, and through cuts or punctured skin. These types of routes through the body causes Neisseria gonorrhoeae to infect the host. Most of the microbes will enter the host causing disease to occur, from that same host and eventually spread the disease throughout the body, developing new hosts.…

    Multi-drug resistant Neisseria gonorrhoeae has been classified as an urgent threat by the Center for Disease Control and Prevention (CDC). N. gonorrhea is a sexually transmitted disease that affects approximately 820,000 people annually, 246,000 of those cases are drug-resistant strains (CDC, 2013). The concern with these infections is the rapid spreading from those infected to the healthy population and the existing limitations for treatment of those individuals with resistant strain infections. N. gonorrhea infections can result in severe reproductive complication and is significantly more prevalent in minority communities. Based on data found with the CDC, the and associated costs are $235 million (CDC, 2013).…
