β-lactam antibiotics (beta-lactam antibiotics) are antibiotics that contain a beta-lactam ring in their chemical structure. This includes penicillin derivatives , cephalosporins and cephamycins , monobactams, carbapenems and carbacephems.
The β-lactam core structures. (A) A penam.(B) A carbapenam.(C) An oxapenam.(D) A penem.(E) A carbapenem.(F) A monobactam.(G) A cephem.(H) A carbacephem.(I) An oxacephem. This is a list of common β-lactam antibiotics—both administered drugs and those not in clinical use—organized by structural class.
An antibiotic is a type of antimicrobial substance active against bacteria. It is the most important type of antibacterial agent for fighting bacterial infections, and antibiotic medications are widely used in the treatment and prevention of such infections. [1] [2] They may either kill or inhibit the growth of bacteria.
The two types of beta decay are known as beta minus and beta plus. In beta minus (β − ) decay, a neutron is converted to a proton, and the process creates an electron and an electron antineutrino ; while in beta plus (β + ) decay, a proton is converted to a neutron and the process creates a positron and an electron neutrino. β + decay is ...
Same mode of action as other beta-lactam antibiotics: disrupt the synthesis of the peptidoglycan layer of bacterial cell walls. Cefazolin: Ancef, Kefzol: Cephradine: Cephapirin: Cephalothin: Cefalexin: Keflex: Cephalosporins (Second generation) Cefaclor: Distaclor, Ceclor, Raniclor: Less Gram-positive cover, improved Gram-negative cover.
The most important use of beta-lactamase inhibitors is in the treatment of infections known or believed to be caused by gram-negative bacteria, as beta-lactamase production is an important contributor to beta-lactam resistance in these pathogens.
Positron emission, beta plus decay, or β + decay is a subtype of radioactive decay called beta decay, in which a proton inside a radionuclide nucleus is converted into a neutron while releasing a positron and an electron neutrino (ν e). Positron emission is mediated by the weak force.
Nitrofurantoin. 270 to 272 °C (518 to 522 °F) (decomp.) Nitrofurantoin is an antibacterial medication of the nitrofuran class used to treat urinary tract infections, although it is not as effective for kidney infections. [2] It is taken by mouth. [2] Common side effects include nausea, loss of appetite, diarrhea, and headaches. [2]
Amphotericin B is an antifungal medication used for serious fungal infections and leishmaniasis. [3] The fungal infections it is used to treat include mucormycosis, aspergillosis, blastomycosis, candidiasis, coccidioidomycosis, and cryptococcosis. [4] For certain infections it is given with flucytosine. [5]
Antibiotic sensitivity testing or antibiotic susceptibility testing is the measurement of the susceptibility of bacteria to antibiotics. It is used because bacteria may have resistance to some antibiotics.
