cells that are useful in fighting infection. Inflammation of the tonsils can be caused by many contagious bacteria or viruses‚ including strains of streptococcus bacteria‚ adenovirus‚ influenza virus‚ Epstein-Barr virus‚ enterovirus‚ and the herpes simplex virus. One of the most frequent causes of tonsillitis is group A beta hemolytic Streptococcus pyogenes (GABHS)‚ which is also the cause of strep throat; it is responsible for 30% of childhood tonsillitis and 10% of adult cases (Lauro).

until 10 years old. There are several factors that cause scarlet fever in children. Firstly‚ children who get scarlet fever because of an infection from a bacterium called exotoxin-producing group A beta-hemolytic streptococci (GABHS)‚ notably Streptococcus pyogenic. This bacterium will release of a particular toxin that responsible for the characteristics scarlet-coloured rash seen with scarlet fever. In the majority of cases‚ scarlet fever occurs as a result of pharyngeal streptococcal infection

Pseudomonas syringae Finding a bacterium that I felt even a shred of confidence to discuss in a paper was no easy task‚ but while doing research I discovered this (probably more well-known than I realize) bacteria that had some properties that were incredibly interesting to me. The basic properties of Pseudomonas syringae is that it ’s gram-negative‚ has a rod-shaped morphology‚ and is an aerobic respirator. It ’s categorized as gram-negative due to crystal violet being washed away‚ and stained

Necrotizing Fasciitis Necrotizing fasciitis is a bacterial infection that attacks the soft tissue and the fascia. It is commonly known as the “flesh-eating bacteria”. The term flesh- eating bacteria is not really the word for the disease‚ as the bacteria does not actually eat the tissue. It also progresses very quickly‚ greater risk of developing in immunocompromised patients due to conditions such as diabetes and cancer. As the bacterial can be developed in many ways‚ after abdominal surgery

Health inequities are preventable‚ socially produced disparities in the health of groups of people that are systematic in their unequal and unfair distribution across the population (1). This is unlike the similar and often inaccurately substituted word “inequality” which merely refers to the uneven distribution of health status or health resources. Equitable health care ensures equal access and utilisation of services for equal need. To achieve this it must be recognised that different populations

Title: Catalase enzyme detection Objective: To understand the function of catalase in cells that produce the enzyme‚ interpret the results of a catalase test and know their value in differentiating bacteria. Materials: 1 clean microscopic slide‚ 3% H2O2 solution‚ swabs. Micrococcus luteus‚ Enterococcus faecalis‚ patient G Procedure: 1) Scrape some cells off from each bateria to the slant and place them on glass slide. 2) Place one or two drops of H2O2.

Streptococcus pyogenes Research paper MCB 2010C March 17‚ 2014 Nature of Causative Organism Streptococcus pyogenes‚ a group A streptococci‚ is a gram-positive‚ non-spore forming bacteria that can be seen as oval cocci chain forming shapes less than 2 micrometers in diameter under the microscope. It is a facultative anaerobe that can use fermentation for its metabolism. It needs a blood containing medium to grow and exhibits beta-hemolysis. It is a non-motile‚ nonspore forming bacterium.

Description Necrotizing Fasciitis is a term for a rare but very severe condition of rapidly spreading infection in the skin‚ fat‚ and a band of connective tissue covering the muscle called the fascia. The bacterium known as Streptococcus Pyogenes enters the body through a wound and releases deadly toxins as it consumes and multiplies the surrounding tissue‚ eventually adding TSS (Toxic Shock Syndrome) to the infection. The release of toxins eventually leads to necrosis (the premature death of
