A staphylococcal infection or staph infection is an infection caused by members of the Staphylococcus genus of bacteria. These bacteria commonly inhabit the skin and nose where they are innocuous, but may enter the body through cuts or abrasions which may be nearly invisible. Once inside the body, the bacteria may spread to a number of body ...
Staphylococcus aureus. Colorized scanning electron micrograph of a human neutrophil ingesting MRSA. Methicillin-resistant Staphylococcus aureus ( MRSA) is a group of gram-positive bacteria that are genetically distinct from other strains of Staphylococcus aureus. MRSA is responsible for several difficult-to-treat infections in humans.
Mercer protocol. The Mercer protocol is a common regimen for antibiotic prophylaxis in the context of preterm premature rupture of membranes (PPROM) during pregnancy, when immediate delivery is contraindicated due to known or suspected fetal lung immaturity. It was first described by Mercer et al. in 1997.
Staphylococcal enteritis. Staphylococcal enteritis is an inflammation that is usually caused by eating or drinking substances contaminated with staph enterotoxin. The toxin, not the bacterium, settles in the small intestine and causes inflammation and swelling. This in turn can cause abdominal pain, cramping, dehydration, diarrhea and fever. [1]
Vancomycin-resistant Staphylococcus aureus ( VRSA) are strains of Staphylococcus aureus that have acquired resistance to the glycopeptide antibiotic vancomycin. [3] Bacteria can acquire resistant genes either by random mutation or through the transfer of DNA from one bacterium to another. Resistance genes interfere with the normal antibiotic ...
Penicillin resistance in Staphylococcus aureus appeared very soon after penicillin entered general clinical use in 1943, and the mechanism of resistance was the production of β-lactamase. Modification of the penicillin molecule so that it was resistant to being broken down by β-lactamase was able to temporarily overcome this problem.
Staphylococcus aureus is a Gram-positive spherically shaped bacterium, a member of the Bacillota, and is a usual member of the microbiota of the body, frequently found in the upper respiratory tract and on the skin. It is often positive for catalase and nitrate reduction and is a facultative anaerobe that can grow without the need for oxygen.
Staphylococcus. Species: S. saprophyticus. Binomial name. Staphylococcus saprophyticus. (Fairbrother 1940) Shaw et al. 1951. Staphylococcus saprophyticus is a Gram-positive coccus belonging to the genus Staphylococcus. [1] S. saprophyticus is a common cause of community-acquired urinary tract infections. [2] [3]
