The best example is that of penicillin which has evolved with numerous derivatives, progressively improved. Thus, the results of the present study emphasize the necessity of genotypic resistance research in future studies to help maintain antibiotic treatment efficacy for Enterocatericeae infections. Always consult your healthcare provider to ensure the information displayed on this page applies to your personal circumstances. Tetracycline has a chemical formula of C 22 H 24 N 2 O 8 and a molecular mass of 444. Later on, it was spread all over Europe. J Intern Med 1999; 246: 591-2.
Prescriptions of these drugs should be discarded once expired because they can cause hepatotoxicity. Tetracyclines are widely used for veterinary therapy.

Effects of tetracyclines on experimental Legionella pneumophila infection in guinea-pigs. Severe episode of high fever with rash, lymphadenopathy, neutropenia, and eosinophilia after minocycline therapy for acne. Their biologic activity against a wide spectrum of microbial pathogens and their uses in mammalian models of inflammation, neurodegeneration, and other biological systems indicate that the tetracyclines will continue to be successful therapeutics in infectious diseases and as potential therapeutics against inflammation-based mammalian cell diseases. Drug Interactions in Infectious Diseases. You must ultimately rely on your own discretion, experience, and judgment in diagnosing, treating, and advising patients.
