Ampicillin Description and Application

Ampicillin is less effective than most penicillins for most Gram-positive bacteria. However, it has a strong effect on most Gram-negative bacteria, such as Escherichia coli, Proteus, Salmonella, Haemophilus, Brucella and Pasteurella, similar to or slightly stronger than chloramphenicol and tetracycline. However, the toxic effect is less than chloramphenicol or tetracycline. It is not effective against Staphylococcus aureus and Pseudomonas aeruginosa Ampicillin is widely used in human and animal lungs, urinary tract infections and certain infections caused by Gram-negative bacilli caused by sensitive bacteria, such as human meningitis, endocarditis, etc.; sputum, sputum pneumonia, bovine Pasteurellosis , пневмония, mastitis, porcine contagious pleuropneumonia, chicken white mites, poultry typhoid and so on. Ampicillin is susceptible to decomposition by β-lactamase produced by bacteria, which reduces the therapeutic effect. It is often used in combination with the synthetic β-lactamase inhibitor-sulbactam to increase its synergistic effect. Its antibacterial activity has expanded its antibacterial spectrum. In addition, ampicillin and aminoglycoside antibiotics also have synergistic effects, which can enhance the efficacy.
