Staphylococcus

 [staf″ĭ-lo-kok´us]
a genus of gram-positive bacteria made up of spherical microorganisms, tending to occur in grapelike clusters; they are constantly present on the skin and in the upper respiratory tract and are the most common cause of localized suppurating infections. Pathogenic species include S. au´reus, S. epider´midis, and S. saprophy´ticus.S. aureus is also a cause of food poisoning.

staphylococcus

 [staf″ĭ-lo-kok´us]
any organism of the genus Staphylococcus. adj., adj staphylococ´cal, staphylococ´cic.

Staphylococcus

(staf'i-lō-kok'ŭs), Avoid the misspelling/mispronunciation Staphlococcus.
A genus of nonmotile, nonspore-forming, aerobic to facultatively anaerobic bacteria (family Micrococcaceae) containing gram-positive, spheric cells, 0.5-1.5 mcm in diameter, which divide in more than one plane to form irregular clusters. These organisms are chemoorganotrophic, and their metabolism is respiratory and fermentative. Under anaerobic conditions, lactic acid is produced from glucose; under aerobic conditions, acetic acid and small amounts of CO2 are produced. Coagulase-positive strains produce a variety of toxins and are therefore potentially pathogenic and may cause food poisoning. These organisms are usually susceptible to antibiotics such as the β-lactam and macrolide antibiotics, tetracyclines, novobiocin, and chloramphenicol but are resistant to polymyxin and polyenes. They are susceptible to antibacterials such as phenols and their derivatives, surface-active compounds, salicylanilides, carbanilides, and halogens (chlorine and iodine) and their derivatives, such as chloramines and iodophors. They are found on the skin, in skin glands, on the nasal and other mucous membranes of warm-blooded animals, and in various food products. The type species is Staphylococcus aureus.

Patient discussion about Staphylococcus

Q. can staphylococcus in woman cause infertility? staphylococcus/infertility

A. Not that I know about. One of the major routes in which bacteria cause infertility in women is through inflammation of the pelvis (PID), but staphylococcus isn't a major cause of this disease.

Q. what is staph hominis subspec hominis? my grandmother has it and she also has breast ca diabetes is it contagi contagious and what causes it

A. 2. Staphylococcus hominis is a bacterium. That lives harmlessly on humans (like many other bacteria) and trouble begins when someone get immuno compromised. your grandmother probably having harsh chemotherapy and radiations. Her immune system is week and cannot defend the body from infections. Unluckily the Staph hominis somehow penetrated and caused an infection.

Q. What is MRSA? I’ve heard on the news that some hospitals have a higher rate of MRSA infection. What is MRSA?

A.
MRSA - Methicillin-Resistant Staphylococcus Aureus, is a nick name for a specific subtype of bacteria from the Staph bacteria family, which is found resistant to many of the common antibiotics that are in use today. This is due to a mutation development in the Staph bacteria, which allowed it to grow resistance against the killing ingredient in common antibiotics, therefore making it a harder infection to treat and cure. Hospitals keep track of their MRSA infections for epidemiological reasons, in order to get a perspective on bacterial resistance to antibiotics, hoping new and more effective antibiotic medication will be researched.
