Pneumoniae Bacteria Essay
S. pneumonia is cultivated in the anaerobic condition in blood or chocolate agar in thirty-seven degrees celsius and is incubated for twenty-four hours; this increases the bacteria growth by five to ten percent. The characteristic of the culture of S. pneumonia is a small smooth colony with alpha hemolysis. S. pneumoniae pathogenic strain forms large polysaccharides capsules and their cell wall is a common peptidoglycan layer.
The peptidoglycan layer has a backbone of N-acetyl glucosamine and N-acetylmuramic acids that are present in both Gram positive …show more content…
The type-specific antibody of the capsular polysaccharide is a protective barrier. The antibodies enable the destruction of pneumococci via phagocytosis and the elimination of S. pneumoniae.
Pneumococci are mostly found in the upper respiratory tract and may be isolated from the nasopharynx. The onset of the bacteria is generally longer in children than adults. Since 2011, ninety-two serotypes have been …show more content…
The incubation period of pneumococcal pneumonia is acute, from one to three days. The symptoms include sudden onset of fever and chills, sharp chest pain, cough, production of both mucus and pus, dry sputum, dyspnea, hypoxia, abnormally rapid breathing, abnormal heart rate, discomfort feeling, and weakness. Pneumonia is followed by upper or middle respiratory viral infection which then transforms to S.pneumonia of pulmonary parenchyma. The symptoms include increased amount and thick secretions that are more difficult to clear.
Pneumococcal bacteremia is a result of pneumococcal pneumonia bacteria in the blood stream. Symptoms include fever, headache and muscular aches and pains. Bacteremia without an unknown site of infection is a fairly common medical condition of pneumococcal infection in children of two years old or younger. The bacteremia can develop into secondary complications, such as arthritis, meningitis, and/or endocarditis may occur.
Otitis Media is the inflammation of the middle ear and is very common in children which are caused by pneumococci. Symptoms include pain in the ear, loss of hearing, the rise in body temperature, nausea, and
