how do b lactam antibiotics work?
318433
β-lactam antibiotics are bactericidal, and act by inhibiting the synthesis of the peptidoglycan layer of bacterial cell walls. The peptidoglycan layer is important for cell wall structural integrity, especially in Gram-positive organisms, being the outermost and primary component of the wall.

Bactericidal antibiotics kill bacteria; bacteriostatic antibiotics slow their growth or reproduction. Bactericidal antibiotics that inhibit cell wall synthesis: the beta-lactam antibiotics (penicillin derivatives (penams), cephalosporins (cephems), monobactams, and carbapenems) and vancomycin.

It is a macrolide-type antibiotic. It works by stopping the growth of bacteria. This medication will not work for viral infections (such as common cold, flu). Unnecessary use or misuse of any antibiotic can lead to its decreased effectiveness.

Ampicillin (AMP), a semi-synthetic β-lactam antibiotics, is widely used to treat of human and livestock E. coli infection, but recently its resistance rate has increased. AMP works on the active replicating stage of bacteria, inhibiting the synthesis of bacterial cell wall.

β-Lactam antibiotics are used extensively in veterinary medicine. β-Lactam antibiotics include penicillins, oxacillin, amoxicillin, ampicillin, carbpenicillin, and others. Emerging resistance has compromised their use. Several resistance mechanisms exist but the most commonly studied is β-lactamase production.

Cefuroxime is a cephalosporin (SEF a low spor in) antibiotic. It works by fighting bacteria in your body. Cefuroxime is used to treat many kinds of bacterial infections, including severe or life-threatening forms. Cefuroxime may also be used for purposes not listed in this medication guide.

The following antibiotics are used to treat UTIs: Beta-lactams, including penicillins and cephalosporins (for example, Amoxicillin, Augmentin, Keflex, Duricef, Ceftin, Lorabid, Rocephin, Cephalexin, Suprax, and others); many organisms have resistance to some of these drugs.

Ceftriaxone is used to treat a wide variety of bacterial infections. This medication belongs to a class of drugs known as cephalosporin antibiotics. It works by stopping the growth of bacteria.
1369469
USES: Amoxicillin is a penicillin-type antibiotic used to treat a wide variety of bacterial infections. It works by stopping the growth of bacteria. This antibiotic treats only bacterial infections. It will not work for viral infections (e.g., common cold, flu).

Azithromycin is a type of antibiotic called a macrolide. It works by preventing bacteria from producing proteins that are essential to them. Without these proteins the bacteria cannot grow, replicate and increase in numbers. The bacteria eventually die or are destroyed by the immune system.

MONOBACTAMS. Aztreonam is a monobactam antibiotic that contains a betalactam ring. However, unlike other beta-lactam antibiotics, aztreonam does not contain a bicyclic-ring structure (6). To date, aztreonam has not demonstrated clinical cross-reactivity in penicillin-allergic patients (2, 8).
1434368
Cefuroxime is used to treat a wide variety of bacterial infections. This medication is known as a cephalosporin antibiotic. It works by stopping the growth of bacteria.

What Is Ceftin? Ceftin (cefuroxime) is a cephalosporin antibiotic. Ceftin is available as a generic drug and is prescribed to treat infections with susceptible bacteria including skin and middle ear infections, tonsillitis, throat infections, laryngitis, bronchitis, pneumonia, urinary tract infections, and gonorrhea.

Cephalosporins are bactericidal beta-lactamantibiotics. They inhibit enzymes in the cell wall of susceptible bacteria, disrupting cell synthesis.

Amoxicillin/Clavulanic Acid 875 mg/125 mg is an antibiotic and works by killing bacteria that cause infections. It contains two different medicines called amoxicillin and clavulanic acid.

While investigating the side effects of antibiotics and how bacteria can develop resistance to them, researchers from MIT and Harvard have found that the drugs can actually work against the body, weakening the immune system's ability to fight off the bugs.
978603
Cloxacillin is used to treat a wide variety of bacterial infections. This medication is a type of penicillin antibiotic. It works by stopping the growth of bacteria. This antibiotic treats only bacterial infections.
