Their basic structure consists of the beta-lactam ring and a side chain. The ring structure confers antimicrobial activity, and the side chain determines the antibacterial spectrum and pharmacologic properties. The antibacterial activity of aminopenicillins is similar to that of other penicillins via inhibition of bacterial cell wall synthesis. Penicillin-sensitive reactions in bacterial cell wall synthesis are catalyzed by a class of proteins called penicillin-binding proteins (PBPs), which are inhibited by beta-lactam antibiotics. The antibacterial spectrum of aminopenicillins includes nonbeta-lactamase-producing gram-positive cocci, anaerobes, and gram-negative cocci, including Neisseria and Enterobacteriacae that do not produce beta-lactamase. These agents are not active against Pseudomonas sp and are hydrolyzed by beta-lactamases, making them ineffective against beta-lactamase-producing strains of bacteria. Ampicillin is effective in treating upper and lower respiratory tract infections caused by Streptococcus pneumoniae , beta-hemolytic streptococci, and nonbeta-lactamase-producing strains of Haemophilus influenzae . It also is effective in the treatment of meningitis caused by group B streptococci, Listeria monocytogenes … [1]: {openurl}?query=rft.jtitle%253DPediatrics%26rft.stitle%253DPediatrics%26rft.issn%253D0031-4005%26rft.aulast%253DSubcommittee%2Bon%2BManagement%2Bof%2BAcute%2BOtitis%2BMedia%26rft.auinit1%253D%2B%26rft.volume%253D113%26rft.issue%253D5%26rft.spage%253D1451%26rft.epage%253D1465%26rft.atitle%253DDiagnosis%2Band%2BManagement%2Bof%2BAcute%2BOtitis%2BMedia%26rft_id%253Dinfo%253Adoi%252F10.1542%252Fpeds.113.5.1451%26rft_id%253Dinfo%253Apmid%252F15121972%26rft.genre%253Darticle%26rft_val_fmt%253Dinfo%253Aofi%252Ffmt%253Akev%253Amtx%253Ajournal%26ctx_ver%253DZ39.88-2004%26url_ver%253DZ39.88-2004%26url_ctx_fmt%253Dinfo%253Aofi%252Ffmt%253Akev%253Amtx%253Actx [2]: /lookup/ijlink?linkType=ABST&journalCode=pediatrics&resid=113/5/1451&atom=%2Fpedsinreview%2F27%2F11%2F434.atom [3]: {openurl}?query=rft.jtitle%253DPediatrics%26rft.stitle%253DPediatrics%26rft.issn%253D0031-4005%26rft.aulast%253DSubcommittee%2Bon%2BManagement%2Bof%2BSinusitis%2Band%2BCommit%26rft.auinit1%253D%2B%26rft.volume%253D108%26rft.issue%253D3%26rft.spage%253D798%26rft.epage%253D808%26rft.atitle%253DClinical%2BPractice%2BGuideline%253A%2BManagement%2Bof%2BSinusitis%26rft_id%253Dinfo%253Apmid%252F11533355%26rft.genre%253Darticle%26rft_val_fmt%253Dinfo%253Aofi%252Ffmt%253Akev%253Amtx%253Ajournal%26ctx_ver%253DZ39.88-2004%26url_ver%253DZ39.88-2004%26url_ctx_fmt%253Dinfo%253Aofi%252Ffmt%253Akev%253Amtx%253Actx [4]: /lookup/ijlink?linkType=ABST&journalCode=pediatrics&resid=108/3/798&atom=%2Fpedsinreview%2F27%2F11%2F434.atom
