what did you know about stapylococcus infection?

Answer 1

That its not an STD.

Answer 2

Staphylococci can cause a wide variety of diseases in humans and other animals either through toxin production or invasion. Staphylococcal toxins are a common cause of food poisoning. The bacteria grow in improperly stored food. Although the cooking process kills them, the enterotoxins are heat resistant and can survive boiling for several minutes. Staphylococci can grow in foods with relatively low water activity (such as cheese and salami).

One pathogenic species is Staphylococcus aureus, which can infect wounds. These bacteria can survive on dry surfaces, increasing the chance of transmission. Of this type, Methicillin-resistant Staphylococcus aureus (MRSA) has recently become a major cause of hospital-acquired infections and is being recognized with increasing frequency in community acquired infections. S. aureus is also implicated in toxic shock syndrome; during the 1980s some tampons allowed the rapid growth of S. aureus, which released toxins that were absorbed into the bloodstream. Any S. aureus infection can cause the staphylococcal scalded skin syndrome, a cutaneous reaction to exotoxin absorbed into the bloodstream. It can also cause a type of septicaemia called pyaemia.

The coagulase positive Staphylococcus that inhabits and sometimes infects the skin of domestic dogs and cats is Staphylococcus intermedius. This organism, too, can carry the genetic material that imparts multiple bacterial resistance. It is rarely implicated in infections in humans, as a zoonosis.

S. epidermidis, a coagulase-negative staphylococcus species, is a commensal of the skin, but can cause severe infections in immune suppressed patients and those with central venous catheters.

S. saprophyticus, another coagulase-negative species, is predominantly implicated in genitourinary tract infections in sexually active young women.

In recent years several other Staphylococcus species have been implicated in human infections, notably S. lugdunensis, S. schleiferi, and S. caprae.

Staphylococcus can also be found on the tips of the fingers. Most commonly it is found on the index finger as well as the thumb. This infection is known as a felon. As are many other Staphylococcus infections, felon is very painful and can be treated with antibiotics. Most S. aureus are penicillin resistant, but vancomycin and nafcillin are known to be effective against most strains.
