Streptococcus pneumoniae

Streptococcus pyogenes, also known as Group A streptococcus (GAS), is a β-hemolytic, Gram-positive bacterium that most commonly causes respiratory disease, including pharyngitis or tonsillitis, as well as skin infections such as impetigo and cellulitis. The organism is transmitted via respiratory droplets or by contact with fomites, and commonly infects young children. In addition to the common clinical presentations associated with S. pyogenes, some individuals develop the postinfectious sequelae

Truman Nord Biol 231L Sec.3 November 11, 2014 Identifying Unknown Bacteria: Streptococcus agalactiae Introduction: This experiment was conducted to find the genus and species of an unknown bacteria prescribed by the lab teacher, which was unknown bacteria GA3 in my case. Identification of unknown bacteria techniques are used on an every day basis to figure out what type of bacteria it is and to find the best method of how to treat a patient with this bacteria (1). All five “I’s” of Microbiology

During the study period from 2006 to 2014, three hundred sixty patients with a definitive infective endocarditis diagnosis were included. The mean age of the patients was 53 ± 13 (range 18–94). Two hundred thirteen (59%) patients were male and one hundred forty seven were female. 80 of the 362 patients died during hospitalization and in- hospital mortality rate was 22% for the entire study. A total of 295 (83%) of the patients were African American. 76patients had a previous episode of IE (21%).

Rheumatic fever is an autoimmune response that develops from group A Streptococcal infection (GAS) (Webb & Wilson, 2013). When left undiagnosed, this can led to rheumatic heart disease (RHD), which continues to cause over 200 deaths yearly in New Zealand (Gilbert, Wilson & Finucane, 2011). This disease affects Māori at a significantly higher rate than any other ethnicity in New Zealand (Wilson, 2010). Rheumatic fever is an important topic because it is vital to address the concerning cases in New

Ashley Calhoun October 6, 2014 Streptococcus pneumonia Streptococcus pneumonia is a pathogen with a niche in the upper respiratory tract of the human that has a two component signaling system. The two component signaling system has CPS accumulate extracellular to the cell, CPS eventually binding to the comD receptor, which stimulates auto-phosphorylation of comE, the response regulator(1). This is a strictly fermenting microbe that tolerates oxygen’s presence, also known as an aerotolerant pathogen

Normal childhood infections and injuries are fairly simple to diagnose in childhood. It is simple to take a throat swab to find out if the teenager has strep throat or not. Unfortunately, some children have symptoms that are harder to diagnose. They may report symptoms like problems sleeping, fatigue, pain and achiness. While these could be symptoms of a variety of illnesses, it is possible that these symptoms could be caused by fibromyalgia. Known for causing pain in soft tissues and muscles around

he bacterial infection called strep throat is an infection that causes lots of      inflammation,swelling, and pain inside the throat and also tonsils. This       bacterial infection is caused by group A Streptococcus bacteria. (Which is a         microorganism that is often found in the throat and on the skin.)                                Strep Throat may occur in the throat but may potentially travel to                     body parts.The transmission of strep throat can happen by coughing,

The first step in any bacterial infection involves the attachment of bacteria to the host surface, which followed by colonisation, and infection. Streptococcus pneumonia is a significant human pathogenic bacterium; organism causes invasive diseases such as sepsis, meningitis, pneumonia and some more disease in human. In pneumonia it attaches to nasopharyngeal cells through interaction of bacterial surface adhesins. Tao Wang et al (47) reported that Big Domain ( bacterial immunoglobulin like) of

This experiment was conducted to first, determine if Staphylococcus is present in the nose cavity. Staphylococcus is very common in in the nasal cavities and therefor its highly likely that some type of Staphylococcus will be detected. In order to detect the presence of Staphylococcus a nose swab will be taken and incubated at 37.0˚C for 48hrs in a (m-G+C) broth. This broth has a 10% salt concentration and as Staphylococcus is a halophile and requires salt to flourish, the salt concentration in this
