relieve the anxiety caused by the obsessions. All of these areas are directly affected by serotonin. A biological factor of OCD that is still being researched in depth is the effects of streptococcus, this is the bacteria that causes strep throat. As of now, some researchers believe that an infection with streptococcus can cause a development of OCD in children when the body tries to produce antibodies to fight the infection that end up reacting to the basal…

“My child was fine last week, last month – and now I have lost her. This is not my child; what has happened? What do I do? (Sudden & Severe Onset)” For every parent with a child that has an illness, this seems to be a recurring story. Many parents and specialists are desperate for an explanation that makes sense as to why this a child may be fine one day and a completely different child the next, and unfortunately do not find answers. Pediatric Autoimmune Neuropsychiatric Disorders Associated…

non-hemolytic (gamma hemolysis). Growth best resembled the control Staphylococcus epidermidis which is non-hemolytic, indicating that Unknown 15 did not produce hemolysins to lyse RBCs into hemoglobin (1). Therefore, the alpha and beta hemolytic genus Streptococcus was eliminated (5). There was not an inconsistency in this result but, rather, a variability. The species that Unknown 15 was identified to be, by BLAST sequencing, can either demonstrate alpha or gamma hemolytic activity. If it is…

Disease: Strep throat Causative Agent: Streptococcus pyogenes Morphology of Causing Agent: The bacterium S. pyogenes is spherical and emerges in chain-like structures. Gram-staining reveals that this bacterium is gram positive since it shows up dark purple. Transmission: Strep throat is highly contagious and primarily spreads when airborne by coughing or sneezing. Diagnosis: The most common way to diagnose strep throat is by having a trusted doctor perform a rapid antigen test after collecting…

Literature Research: Staphylococcus is a type of Gram-positive bacteria that are commonly found together in random clusters. They are sometimes found in the same habitat as Micrococcus and can be differentiated because of the occurrence of cytochromes (5). They are typically facultative anaerobes or microaerophils and are able to produce catalase, making it possible for them to convert hydrogen peroxide to water to avoid potential damage. The major product of fermentation is lactate and they…

test was used as a selective and differential medium. The bile that was in the medium was selective for streptococci and enterococci and inhibited the growth of Gram-positive staphylococci (Atlas & Snyder, 2015). The test differentiated between Streptococcus bovis group and Enterococcus from other streptococci based on the bacteria’s ability to hydrolyze esculin in the presence of bile. When esculin is hydrolyzed the byproduct reacts with ferric citrate and forms a dark precipitate on the medium…

Introduction Streptococcus pyogenes is a bacteria responsible for a wide range of diseases. They include pharyngitis, impetigo, a skin infection, scarlet fever, rheumatic fever, and toxic shock syndrome (TSS) (Burch, 2008). However, the focus of this research will be on necrotizing fasciitis (NF). Although necrotizing fasciitis is rare, it can be lethal. It is commonly known as “flesh-eating bacteria” (touching base, 2001) for its ability to destroy the skin tissue. For the most part, it is…

Streptococcus Equi, More commonly known as Strangles is an infectious equine disease that is characterized by attacking and breaking down the lymphoid tissue of the upper respiratory tract making this disease fatal. Streptococcus is a type of bacterium which causes the disease. Strangles got its name because historically, affected horses were sometimes suffocated from inflamed lymph nodes in their upper airway and trachea.When a horse gets this disease the bacteria cells attach to the tonsil…

Group A Streptococcus is a bacterium that can cause a wide range of infections. People may also carry group A streptococci in the throat or on the skin and have no symptoms of illness. Most group A strep infections are relatively mild illnesses such as strep throat, or impetigo. Occasionally these bacteria can cause severe and even life-threatening diseases. These bacteria are spread through direct contact with mucus from the nose or throat of people who are sick with a group A strep infection…

mouth is home to billions of individual microorganisms, including viruses, protozoa, fungi, archaea, and bacteria” (University of Minnesota Department of Biology Teaching and Learning, 2016, p. 21). 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…
