Streptococcus pneumoniae

bactericidal factors causing bacterial cell death. Furthermore, Klebsiella Pneumonia holds virulent factors to help the infection process. The cell wall of the bacterium contains receptors that allow it to adhere to the host cells. By doing so, Klebsiella Pneumoniae can impair macrophages and leukocytes and prevent phagocytosis, as the attachment alters the bacterial…

Infectious diseases and Infections Infectious diseases are caused by microorganisms, such as bacteria, viruses and fungi. Many microorganisms live in our body and in our environment, in which most of them are advantageous such as bacteria found in our intestine is useful for food digestion and fungi used for foods such as mushrooms and yeast. However, in certain conditions these organisms can also cause illnesses. Infectious diseases can be transmitted, directly or indirectly, from one person…

factor in the pathogenesis of middle ear infections and effusion is the obstruction of the Eustachian tube. The back-up of nasopharyngeal secretions leads to the contamination of the middle ear fluid. The most common causative agents are Streptococcus pneumoniae, Haemophilus influenza, and Moraxella catarrhalis. Signs and symptoms…

Experimental trials were performed by students over a timeframe of three weeks to determine the identity of three unknown bacteria contained in broth medium stored in labeled test tubes that were randomly assigned containing: one Gram positive bacterium, one Gram-negative paracolon, and one Gram-negative coliform (Carson, 2016). The unknown sample assigned in this experiment was #19. After initially streaking the solution on clean streak plates and TSA agar, the identity was determined from a…

Meningitis is an inflammation of the brain and spinal cord, most often caused by viral infection, while bacterial and fungal infections are also possible causes. The first major recorded outbreak of Meningitis was in Geneva, in 1805. Meningitis can affect anyone, regardless of age, race or ethnicity, but the groups that are most susceptible to infection are infants between the ages of 6 and 18 months of age, children under the age of 5 years old, young adults, elderly people and anyone with an…

out of 193 World Health Organization members have organized the vaccination of children (Brouwer et al 2010). Specifically, in African countries where there is a high incidence of HIV, most of the cases of bacterial meningitis are caused by S. pneumoniae, causing high mortality rates. Haemophaelus influenzae is another leading cause of bacterial meningitis. While bacterial meningitis caused by H. influenzae used to account for 45 to 48% of all cases in the US, it now only accounts for 7%…

of teixobactin which made the bacteria hard to alter the molecules and develop resistance against it. According to Piddock L.V., teixobactin is able to reduce the bacterial load effectively in the experimental infections of MRSA and also Streptococcus pneumoniae in mice. Although teixobactin is found to be effective against MRSA and other infections that caused by Gram positive bacteria, however, teixobactin does have its limitation. Primarily, the antibiotic only being tested on mice. This is…

Asplenic patients are at high risk for infection by encapsulated organisms due to a decreased ability to clear them. This increased risk is due to a decrease in IgM, opsonins, and splenic tuftsin. The most common encapsulated organisms are Streptococcus pneumoniae, Haemophilus influenzae type B (Hib), and Neisseria meningitidis.Vaccination against these organisms is imperative in order to prevent infections and overwhelming post-splenectomy sepsis (OPSS), a serious condition where mortality rate…

serious complications such as brain damage or hearing loss. There are several types of germs that can give bacterial meningitis. Some of the most prevalent strains of bacterial meningitis in the U.S. include Haemophilus influenza, Streptococcus pneumoniae, group B Streptococcus, Listeria monocytogenes, and Neisseria meningitidis. Most of these pathogens are more or less dangerous to certain age people. Meningitis often shows up accompanied by a fever, headache, or stiff neck. They often have…

Pneumonia is caused by an inflammatory response to an organism such as streptococcus pneumoniae or escherichia coli. This inflammation occurs in the alveolar sacs and the alveoli are filled with fluid, neutrophils, and there is also an increase in mucus production.The inflammation of the alveolar sacs leads to a decrease in gas exchange which leads to hypoxia (Lewis, 2014). There are several types of pneumonia and they include: community-acquired, medical care-associated, aspiration, and…
