Streptococcus pneumoniae

Streptococcus Pneumoniae, more often called S. Pneumoniae or Pneumococcus, is a significant human pathogenic bacterium. A normal inhabitant of the upper respiratory tract, approximately 1 in 4 people carries the bacteria asymptomatically. Education on what illnesses the bacteria can cause, the signs and symptoms of the bacteria, who is the most at risk for infection along with how it is transmitted, and possible treatments are crucial to understanding the bacteria and helping to stop the spread.

Streptococcus pneumoniae, commonly called S. Pneumoniae or Pneumonccus, is a significant human pathogenic bacterium. This bacteria can cause a wide variety of illnesses depending on where the bacteria occupies. It is found in the respiratory tract, nasopharynx or the blood stream. Conditions that may develop from Streptococcus Pneumoniae of the nasopharynx are: Conjunctivitis, Ottis media and sinusitis. Conditions steaming from bacteria located in the respiratory tract are pneumonia. Conditions that

Invasive pneumococcal disease (IPD) is defined as the recovery of an isolate of S. pneumoniae from a normally sterile site, such as blood, cerebrospinal fluid (CSF), pleural fluid, joint aspirate, pericardial fluid, or peritoneal fluid [1]. Splenic abscesses are rare in the pediatric population [2]. Early recognition and intervention are critical due to the high mortality rate associated with delayed diagnosis [3]. A literature review revealed no case reports of splenic abscesses due to invasive pneumococcal

Pneumonia is an infection of the lower respiratory tract caused by bacteria, viruses, fungi, protozoa, or parasites. (McCance 1290). Microorganisms different than those infections obtained in the hospital produce community-acquired pneumonia. (McCance 1290). Lower respiratory tract infections’ paths include aspiration of oropharyngeal secretions and inhalation of microorganisms released into the air by an infected individual. (McCance 1290). An infection already in the body can spread to the lungs

gram-positive organism, and the morphology distinguished it as a strain of streptococcus, and these finds helped direct the other tests. Hemolytic tests are very useful in differentiating specific species of a certain family of bacteria. The hemolytic test showed the bacterium to be of alpha clearing, which meant it only partially lysed the red blood cells and left a greenish tint. This identified the bacterium as either strep pneumoniae or faecalis. The bacitracin test, which tests whether the bacterium

be Streptococcus Mitis. The results from the MacConkey plate proved the Gram Negative bacteria to be a lactose fermenter. With the Gram Negative bacteria I performed a lysine test with positive results. Next, I performed an ornithine test on the Gram Negative bacteria, with negative results, therefore I concluded the Gram Negative bacteria was Klebsiella pneumoniae. Introduction: The two bacteria from sample number 118 I have identified to be Streptococcus mitis and Klebsiella pneumoniae. When

Introduction: There are two major classes of bacteria that contain peptidoglycan, Gram-positive and Gram- negative. Gram positive bacteria will stain dark purple due to their thick peptidoglycan cell wall, while Gram negative will stain pink due to their thin peptidoglycan cell wall. Many Gram positive and negative bacteria are considered pathogens because they are capable of causing disease in humans. In order to treat properly individuals who are infected with a pathogenic Gram positive or Gram

The genus Streptococcus is classified as a gram positive bacteria because of the spherical or ovoid cells that often arranged in pairs and the color it turns too after undergoing the gram staining technique. Unlike the catalase positive genus Staphylococcus, Streptococcus is catalase negative (Fox). Many Streptococcus bacteria are known to be facultative anaerobes, meaning they prefer to grow in places that have no oxygen but will adjust to places that contain some oxygen (Holt, et al.). On the contrary

selected to be the topic of the research project. 1.3 Mastitis and Klebsiella species Mastitis in dairy animals is caused by a number of bacteria that include the major pathogens such as Streptococcus uberis, Staphylococcus aureus and E. coli. Other mastitis causing pathogens are Streptococcus agalactiae, Streptococcus dysgalactiae, Corynebacterium bovis, Mycoplasma spp., Staphylococcus spp., Klebsiella spp., Citrobactor spp., Enterobacter spp., Pseudomonas aeruginosa, Pasteurella spp. and Bacillus spp

Introduction: Streptococcus iniae is a gram-positive, coccoid first reported in 1976 after being isolated from subcutaneous abscesses in captive Amazon freshwater dolphins (Inia geoffrensis) (Pier & Madin, 1976). S. iniae has since become a major fish pathogen in aquacultures worldwide. Its major significance is as an aetiological agent of streptococcosis in farmed fish and is known to infect tilapia, red drum, hybrid striped bass and rainbow trout (SOURCE). The estimated impact of infections caused
