Common types of drug-resistant bacteria include: mrsa, vrsa, esbl,vre, mrab some of the most powerful antibiotics which these superbugs are sensitive are a class of oxazolidinones drugs such as linezolid, posizolid. The types of antibiotics that are most commonly prescribed to cats are: amoxicillin: probably the most commonly prescribed antibiotic, amoxicillin treats bacterial infections doxycycline: like amoxicillin, doxycycline is also used to fight off bacterial infections.
Antibiotic resistance is the ability of a microorganism to withstand the effects of an antibiotic it is a specific type of drug resistance antibiotic resistance evolves naturally via natural selection through random mutation, but it could also be engineered by applying an evolutionary stress on a. There are many classes of antibiotics for sinus infection know the latest and stronger types of antibiotics in use today to treat sinusitis in adults and children. Penicillin is one of the most commonly prescribed antibiotics it is part of a family of antibiotics known as beta-lactams, and there are many individual medications in this family: penicillin g, nafcillin, oxacillin and dicloxacillin, ampicillin, amoxicillin, carbenicillin, ticarcillin, and piperacillin. A urinary tract infection (uti) is a bacterial infection in the urinary system, which includes the bladder, urethra, ureters and kidneys uti symptoms usually include a frequent urge to urinate, pressure in the lower abdomen and.

Apart from penicillin, the most important antibiotics from fungi are the cephalosporins (beta-lactams with similar mode of action to penicillin, but with less allergenicity) and griseofulvin (from penicillium griseofulvum and related species) which is used to treat althlete's foot and related fungal infections of the skin.

For example, human cells do not have cell walls, while many types of bacteria do the antibiotic penicillin works by keeping a bacterium from building a cell wall bacteria and human cells also differ in the structure of their cell membranes and the machinery they use to build proteins or copy dna.
