Streptococcus mutans

In specific, during this lab we are looking at Streptococcus mutans (S. mutans) and Lactobacilli. In studies, it has been shown that yogurt has helped reduced the amounts of bacteria present in a person’s mouth (Cildir et al., 2009). This could mean that other types of food, maybe even food related to yogurt such as dairy, could help reduce the amount of bacteria present as well. In this lab we asked ourselves, as a group, how can we reduce the amount of S. mutans or…

Gram-positive cocci are an interesting group of bacteria to study. Some common species include Staphylococcus aureus, Staphylococcus epidermidis, Enterococcus faecalis, Streptococcus pyogenes, and Sarcina lutea. Gram-positive cocci have a gram positive cell wall, cocci morphology and many different styles of grouping. Some species have begun to exhibit a resistance to fluoroquinolone by the use of altering the drug binding site and the use of a membrane pump (Hooper 2002). Thanks to the…

ARF are higher in low socioeconomic areas, with 71% of cases being in areas of decile 10 socioeconomic deprivation. Lastly, the Ministry of Health (2015), acknowledged that barriers to health care and decreased treatment opportunities were high among Māori and pacific in cases of strep throat. The Whitehead & Dahlgren’s social model clearly demonstrates many social, biological, economical, and environmental aspects attributed with ARF. Comparatively, the biomedical model would barely illustrate…

differentiated; both of them these can be done either from collected urine from a spontaneously voided urine sample by determination of the protein/creatinine quotient. Hematuria can be characterized as either glomerular or nonglomerular erythrocyturia. The presence of dark brown-colored urine, RBC casts, and dysmorphic, small, deformed, sometimes divided RBCs and proteinuria is indicative of glomerular hematuria. The presence of dysmorphic RBCs and RBC casts indicating that both dysmorphic RBCs…

My professor had suggested that instead of me continuing on ahead doing the catalase test she had recommended that I do a mannitol salt agar test or a Blood agar test for my final test, which would help determine between Streptococcus pneumoniae, Staphylococcus epidermidis. I decided to go along with the mannitol salt agar method and again with my inoculated loop I grabbed some of my unknown #15 and I had applied it to aseptic technique to the agar plate. While waiting for my results to appear,…

the back of the throat and the tonsils. The symptoms of strep throat include sudden pain in the throat without cold symptoms such as coughing or sneezing. Also white or yellow spots on your throat or tonsils, plus a bright red throat or dark red spots on the roof of your mouth or near the back of your mouth towards the throat. This bacterial infection commonly called strep throat is caused from streptococcus pyogenes. Group A streptococcus or GAS is a bacteria commonly found in the throat…

Can a part of normal flora be a killer of the newborns? Grampositive bacterium colonized in 25% of women is THE leading cause of blood infection, pneumonia and meningitis in newborns. GBS can cause babies to be miscarried, stillborn, or become very sick and sometimes even die after birth. Some GBS survivors have permanent handicaps such as blindness, deafness, mental challenges, and/or cerebral palsy. Because of the severity of a GBS infection in the newborn, treatment guidelines have been…

which concluded the genus of the gram positive is Streptococcus. Streptococcus ID introduced many different tests to further identify the gram positive species. One-fourth of the blood agar plate is to determine the hemolysis of the bacteria which is Alpha/Beta because of the partial to complete clearing of the red blood cells. Three-fourth of the plate was used in order to see the susceptibilities of the SXT and Bacitracin discs. There was no zone clearing for SXT which is resistant and 32 mm…

Streptococcus pyogenes Streptococcus pyogenes, also known as impetigo, strep throat, etc., is a flesh eating bacteria, that if left untreated, can lead to very serious symptoms. This bacterium is responsible for a wide array of infections. It can cause a sore throat, that is caused by, fever, enlarged tonsils, and sensitive cervical lymph nodes. Scarlet fever, as well as impetigo, and pneumonia are also caused by this bacterium. The less common infections consist of septicaemia, mastitis,…

These are usually found in the areas of thick, tough skin, such as the back of the neck. They are extremely painful and can be fatal in elderly patients if the carbuncle gives rise to systemic disease. 12. What is osteomyelitis and what are its symptoms? Osteomyelitis occurs when bacteria invade the bones. An abscess forms in the bone and results initially in a tender lump. It can lead to necrosis or breakage of the bone; symptoms include fever, chills, pain and muscle spasms. These are…
