The Effects and Diseases of the Bacterium Streptococcus Pyogenes

Other symptoms of the scarlet fever are a red rash, red lines, flushed face and strawberry tongue. The rash looks similar to sunburn and feels like sandpaper. The rash starts on the face, then moves down to the chest, arms, and legs. Red lines form around the folds of skin around the groin, armpits, elbows, knees and the neck. They are usually more red than the rest of the rash. Scarlet fever also affects the tongue, early on in the fever the tongue may be white. As the illness progresses the person may develop strawberry tongue. This symptom is when the tongue becomes red and bumpy, which also makes it hard for the victim to swallow at times. (Mayo

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 were used in the testing for the unknown culture. Inoculation was used several times to put the unknown culture into agar plates or into biochemical test tubes. After Inoculation of these tubes or plates, they always were placed into the incubator for further growth and development. Isolation was used to make sure we got the correct bacteria we were testing for. After each further isolation, we gram stained the culture and inspected the culture under a microscope to further help in the identification process of the unknown bacteria. Multiple tests were done on the unknown culture to make sure we were confident in what kind of bacteria the unknown was.

Ms. T is an eight year old African American female that presents to Dr. Bill’s Kids today with complaints of her tonsils bothering her again. She has been to this office three times in the past three months with complaints of swollen tonsils and painful swallowing. Each time, she has tested positive for Group A Streptococcus also known as GAS. Her mother is with her today and reports that she had strep throat in the past multiple times about two or three times a year, but it is becoming much more frequent. She began complaining of scratchy throat in the morning and at night, but the symptoms quickly progressed to painful swallowing of solids and liquids. Popsicles are the only thing she will even consider eating at this time because they alleviate the pain.

What are these other serious illnesses that are caused by group A Streptococcus? What is group A Streptococcus? Group A streptococci are bacteria commonly found in the throat and on the skin. The vast majority of GAS infections are relatively mild illnesses, such as strep throat and impetigo. Occasionally, however, these bacteria can cause much more severe and even life threatening diseases such as necrotizing fasciitis (occasionally described as "the flesh-eating bacteria") and streptococcal toxic shock syndrome (STSS). In addition, people may carry group A streptococci in the throat or on the skin and have no symptoms of disease.

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 of rheumatic fever and glomerulonephritis. Due to the severity of these medical consequences, prophylactic antibiotic use is often recommended for any patients with otherwise mild S. pyogenes infections (21).

Group B Streptococcus agalactiae is an important Gram-positive bacterial pathogen that cause a wide variety of clinical infections, ranging from septicemia to meningitis. The reported lethality of severe S. agalactiae infections is ranging from 4 to 6% in the United States. Of note, it has been suggested that the incidence of neonatal disease is considerably greater than reported, because the requirement for positive cultures from blood or cerebrospinal fluid may underestimates the true burden of disease. Therefore, in this review I focused on virulence factors of S. agalactiae in order to elucidate aspects of the infection.

If a streptococcal infection such as pharyngitis or scarlet fever is left untreated, there is a small (~3%) chance that within approximately 20 days, the patient will present with rheumatic fever. After the first bout of rheumatic fever, if the host acquires a second untreated S. Pyogenes infection, the chance of coming down with rheumatic fever jumps substantially to ~50%. Most often this secondary disease will strike people aged 6-15 years old, roughly 20 days after the streptococcal infection, with a 2-5% mortality rate. One of the major diagnostic symptoms of this disease is Erythema Marginatum, snake- or ring-like eruptions covering the trunk, upper arms, and legs. Other symptoms include fever, arthritis (elbows, knees, wrists, and ankles), swollen joints, pain in the abdomen, nodules

Strep throat is a typical sort of sore throat in children, yet it's not extremely regular in adults. Health care professionals can do a quick test to figure out whether a sore throat is strep throat and choose if anti-infective agents are required. Appropriate treatment can help feel better quicker and prohibit spreading it to others. When need to find out the cause to strep throat, health care professionals using by swabbing the throat in order to fast get the result (CDC). I think your research is valuable to what methods are better effective to diagnosis.

Shingles is diagnosed with a skin exam. Sometimes skin or fluid samples are taken from the blisters before a diagnosis is made. These samples are examined under a microscope or sent to a lab for testing.

Acute tonsillitis is inflammation of the tonsils secondary to an infectious process causing painful swallowing and is more commonly attributed to a viral cause rather than bacterial (Shepherd, 2013). A physical assessment of the tonsils may reveal an increase in size with edema and erythema. This is often associated with upper respiratory symptoms like, headache and cough (Shepherd, 2013). Another diagnosis is pharyngitis. Pharyngitis is also a sore throat which is secondary to inflammation noted at the back of the throat and associated with complaints of pain when swallowing (Shepherd, 2013). Viral pharyngitis is the most common and can be contributed to the rhino or coronavirus which lasts between 5-7 days and presents with associated symptoms like cough, headache, fatigue and mild fever (Ruppert & Fay, 2015). Finally, GABHS or more commonly noted as strep throat is a potential diagnosis. This bacterial infection is most common in children and adolescents. Often individuals present with symptoms including throat pain, fever, chills, headache, cervical lymphadenopathy and exudate noted to tonsils or in the pharyngeal (Ruppert & Fay, 2015). This infectious process in younger children may also present with gastrointestinal symptoms like nausea, vomiting and abdominal pain but is not accompanied by cough or nasal

The lab test that would be performed based on Maria history at 37 weeks, will be a blood test done for Group B strep. This is important, because if the women are positive for Group B Strep a antibiotic will need to be administer intravenously , and if not given can cause effects with the fetal. Group B Strep can cause the baby to be born premature.

Rheumatic fever is a disease that can occur following an infection caused by the Group A streptococcus bacterium. If untreated, an infection such as ‘strep throat’ may lead to a delayed complication featuring widespread inflammation in other parts of the body, particularly the joints, heart, skin and brain.

For some reason my sister also gets strep a lot, they told us it was due to eating a lot of ice. My sister also has never had tonsillitis. While doing research I found that Strep and tonsillitis both are an infection causing the throat to become sore. The only real difference is with strep the patient will experience sever soreness to their throat. With tonsillitis the tonsils are inflamed and strep it‘s a specific bacteria that also inflame the throat. I’ve attached a great article on the difference between the two

Streptococcus pyogenes is a very common bacteria found in humans. It is very transmissible and can be caught through the air via coughing or sneezing. This form of Strep. illness is referred to as Streptococcal pharyngitis, also known as Strep. throat, which can complicate into Scarlet Fever. It is also possible to be infected through abrasions of the skin, which can result in cellulitis, impetigo, or even necrotizing fasciitis. Aside from human to human contact, these bacteria can also be found in unpasteurized milk. There is no vaccine for Streptococcal infections, though antibiotics such as penicillin still work very well against them.

A gram stain is performed from the sputum of the infected patient. The presence of neutrophils and greater than ten gram-positive diplococci usually results in the diagnosis of Streptococcus pneumoniae. For further conformation of this organism, it is streaked on blood agar. When on blood agar the organism should
