Will doxycycline stop a staff infection

New antibiotics have been discovered Alexander Fleming, who in 1929 noticed that the staphylococcus colonies are destroyed, if next to them are growing colonies of certain species of fungi. It was discovered penicillin. But in its pure form it could allocate only in 1940. Antibiotics – a matter of microbial, animal or vegetable origin, selectively inhibit the viability of microorganisms. The term “antibiotics” was proposed by S. Waxman in 1942.
Antibiotics are used in medical practice, are produced by radiant fungi (internal hordeolum doxycycline), fungi and some bacteria. This group of drugs also include synthetic analogs of natural antibiotics.
There are antibiotics with antibacterial, antifungal and doxycycline for uti infection activity. Antibiotics affect the microorganisms or suppressing their reproduction (doxycycline rosacea effect), or causing their death (bactericidal effect).
Antibiotics are antimicrobial action on degree of exposure to certain microorganisms are significantly different from each other: some impact mainly on gram-positive bacteria (bacteria that are sufficiently dense shell, so keep the color in the staining of Gram; these include
what is doxycycline used for, streptococci, staphylococci, causative agents tetanus, botulism, etc.), others in Gram-negative (bacteria that are less dense shell, so do not hold the color of Gram staining, these include doxycycline rosacea, gonococcus, dysenteric bacillus, salmonella, etc.), bacteria, others have a broad spectrum actions, including gram-positive and Gram-negative bacteria, what is doxycycline used for (small bacteria, parasites inside the cells of human tissue), chlamydia (large viruses) and several other infectious agents.
By broad-spectrum antibiotics are tetracyclines, levomitsetin, streptomycin, neomycin, monomitsin, kanamycin, ampicillin, imipenem, cephalosporins, rifampicin.
Tetracyclines
Tetracyclines (tetracycline, doxycycline, metatsiklina hydrochloride, vibramitsin and others) have a broad spectrum of activity, they are active against Gram-positive and gram-positive cocci (spherical bacteria), agents of bacillary dysentery, typhoid fever, spirochetes (bacteria elongated and spirally curved), rickettsia , agents of especially dangerous infections (plague, tularemia, cholera), trachoma, and some protozoa (eg, agents of amoebic dysentery). At Proteus, Pseudomonas aeruginosa, the true pathogenic fungi, viruses and tetracyclines do not apply.
The mechanism of action of tetracyclines is related to inhibition of intracellular protein synthesis of bacteria. In addition, tetracyclines bind some trace elements that make up the enzymes of bacteria, which also suspends the vital activity of bacteria. Tetracycline is mainly bacteriostatic doxycycline fatigue particularly effective against multiplying bacteria.
Tetracyclines are absorbed from the stomach and small intestine, not completely, but sufficiently necessary in order to provide the necessary concentration, derived from the urine and bile.
Tetracyclines may have a number of side effects. For example, tetracyclines have an irritant effect: when administered – the mucous membrane of the gastrointestinal tract, resulting in sometimes nausea, vomiting, diarrhea, etc., with intramuscular injection – on the surrounding tissues (the pain after the injection, the inflammation of surrounding veins and t . etc.). Tetracycline can have toxic effects on the liver and cause dysbacterioses, suppressing the normal intestinal microflora.
Cephalosporins
The first group of antibiotic cephalosporins (doxycycline monohydrate pdf) was isolated from the same fungus, was then a large number of semi-synthetic cephalosporin antibiotics. Effective tsefalosporiny bactericidal, ie kill infectious agents.
Tsefalosporiny divided into preparations for oral administration (cephalexin, Cefaclor) and preparations for parenteral (bypassing the gastrointestinal tract) administration (cephalothin, doxycycline for sinus).
Tsefalosporinov disadvantage is that they have a significant percentage of patients cause allergic reactions. Of the non-allergic reactions may damage the kidneys and reduce the number of white blood cells (and hence low immunity). In addition, doxycycline mono have a local irritant effect, so when intramuscular injection may have pain and swelling, and if swallowed – nausea, vomiting and decreased appetite.
