Staphylococcus bacteria

Impetigo is a skin infection that usually occurs in young children living in unsanitary conditions in warm climates. It is caused either by Streptococcus or Staphylococcus bacteria or both together. It produces a tan scab that may disappear in about 10 days, and should be treated with an antibiotic because it is contagious and can cause kidney damage. 

In 2000, a new family of /V-methylthio-substituted p-lactams having promising antibacterial properties has been identified by Turos and coworkers. Curiously, most of this activity is directed towards Staphylococcus bacteria, including methi-cillin-resistant strains of Staphylococcus aureus (MRSA). These p-lactams showed... 

Six years iater, in 1928, Fieming found that one of his piates of Staphylococcus bacteria had been contaminated by a greenish moid, iater identified as Penicillium. He observed it carefuiiy and saw a ciear area around the moid where the bacteria had died, in this case, a chemicai in the moid—peni-ciiiin— was responsibie for kiiiing the bacteria. 

Fleming realized that the Penicillium mold must be producing a chemical that killed the Staphylococcus bacteria, and he spent several years trying to isolate the substance, Finally, in 1939, the Australian pathologist Howard Florey and the German refugee Ernst Chain man-... 

Staphylococcus bacteria are one of the most common causes of skin infection. There are many kinds of staphylococcal skin infections. The least serious is folliculitis, an infection of a hair root that produces a slightly painful pimple at the base of a hair. Most of these infections are minor (pimples and boils) however. Staphylococcus bacteria may also cause serious infections. Impetigo causes shallow, fluid-filled blisters and may itch or hurt. Staphylococcus skin abscesses are warm, painful, collections of pus below the skin surface and staphylococcus cellulitis is a spreading infection that develops under the skin producing pain and redness. More serious skin infections include toxic epidermal necrolysis and scalded skin syndrome in newborns. 

As recently as the late eighteenth century tuberculosis (TB) killed one out five people in Europe. Throughout history the staphylococcus bacteria altered trivial wounds into fatal infections. If one adds cholera, typhus, virulent pneumonia, malaria, and trypanosomal diseases as a partial list, it becomes apparent why the average human life expectancy did not increase significantly from Roman to modem times. 

The shorter the life span, the faster evolution will occur. Thus, the constant and pervasive survival pressure of antibiotics, discovered by Alexander Fleming in 1929, have produced an environment wherein bacteria have developed immunities. In the Oregon Veterans Administration Hospital, the rate of antibiotic resistance of staphylococcus bacteria went from less than 5% to over 80% in a... 

Staphylococcus Bacteria that produces a toxin that causes food poisoning. Normal cooking temperatures do not destroy these organisms.
