Luckily‚ the prognosis of scarlet fever is good‚ (Davis‚ 2016) says that if a patient is treated with antibiotics‚ such as penicillin or amoxicillin‚ scarlet fever only has a mortality rate of 1%. The main risk of scarlet fever lies in the patients that do not get quickly diagnosed and thus do not receive treatment‚ because the mortality rate for those patients drastically increases to 15-20%. Overall‚ if identified and treated quickly‚ scarlet fever is not a very dangerous disease‚ even though it

reality it can affect men‚ children‚ and postmenopausal women. Toxic shock syndrome is rare‚ but it is also life threatening. It often results from complications of types of bacterial infections such as toxins from Staphylococcus aureus or group A streptococcus bacteria. Toxic shock syndrome is associated with having viral infections‚ having cuts or burns on the skin‚ having recent surgery‚ using contraceptive sponges‚ diaphragms‚ or superabsorbent tampons. Toxic shock syndrome can progress rapidly‚ and

It can be caused by one or more bacteria‚ for example Streptococcus pyogenes‚ Kebsiella‚ Bacteroides and more.

Toxic Shock Syndrome is form of blood poisoning caused by overgrowth of Staphylococcus aureus or Streptococcus bacteria. Sometimes these strains of bacteria cause a toxin TSST-1. Its causes have been linked to use of tampons but it can also be caused by surgery and skin wounds. T.S.S. symptoms include a high fever‚ low blood pressure‚ vomiting‚ diarrhea

SMALL SCALE PRODUCTION OF YOGURT Yogurt is a sour milk product. Its sour taste is attributed to the presence of lactic acid yielded by bacteria through fermentation. Bacteria that are commonly used in yoghurt production are Streptococcus thermophilus and Lactobacillus bulgaricus. These bacteria have the ability to break down sugars in the milk producing lactate or lactic acid as by-product. Below is a step-by-step procedure in the production of yogurt. Find out from the procedure why

Dental caries is an irreversible microbial disease of the calcified tissue characterised by demineralization of the inorganic portion and destruction of the organic substance of the tooth which often leads to cavitations. Smoking and its relation to dental caries is a subject of controversy. Early reports in literature indicated that smoking actually helped reducing dental caries (9‚10‚11). Schmidt‚ in 1951‚ supported this belief when he reported that increase in tobacco smoking was followed by
