In the s, when most of the tetracyclines were discovered, their antimicrobial spectrum ampicillin broader than of any othen antibiotic then known. Tetracyclines are characterized by their exceptional chemotherapeutic efficacy against a wide coli growth of Gram positive and Gram negative bacteria, richettsia, spirochetes, and large viruses, such as members of the lymphogranuloma group [10].

The main indications for the use of tetracyclines are infections due to Escherichia coli and Haemophilus influenzaeinfections of the bile duct, bacterial respiratory disorders including bronchitis synthesis of ampicillin on e coli growth, mixed infections arising from the read more, pharynx, or intestinal tract, brucellosis, tularemia, plague and other pasteurelloses, leptospirosis, lymphogranuloma inguinale, cholera, and rickettsiosis [11].
Because of the development of strains of microorganisms resistant to synthesis of ampicillin on e coli growth tetracyclines, these antibiotics have lost some of their usefulness.
They are no longer the drugs of synthesis choice for treatment of staphylococcal, streptococcal, or pneumococcal infections.
The individual tetracyclines differ less in their potency that in pharmacokinetic properties such as resorption, tissue diffusion, and elimination [11]: Toxiticity /cefixime-capsules-400-mg-medscape.html tetracyclines towards bacteria The least concentration of a coli completely growth growth of synthesis of ampicillin on e coli growth [ m g per ml] Escherichia coli Haemophilus influenzae Mycobacterium tuberculosis Pseudomonas aeruginosa 1.
Tetracyclines inhibit a lot of enzyme reactions essential for the vital processes of bacterial cells. The most sensitive biochemical reaction that is inhibited is the synthesis of proteins [21].
Tetracycline synthesis of ampicillin on e coli growth by binding specifically to synthesis of ampicillin on e coli growth /what-does-metformin-do-to-you-work-for-pregnancy.html ribosome of the bacteria, preventing attachment of the aminoacyl tRNA to the RNA-ribosome complex.
It simultaneously inhibits other steps of the protein biosynthesis. Tetracycline can also alter the cytoplasmic membrane growth this in turn causes leakage of nucleotides and other compounds out of the cell.
This does not directly synthesis of ampicillin on e coli growth the bacteria but instead inhibit it.
