What are the classification of Antibacterial Drugs?

Give examples of Natural drugs

Give examples of Semi-synthetic drugs

Give examples of Synthetic drugs

What are the classification of Antimicrobial agents?

Give examples of Bacteriostatic agents

Give examples of Bactericidal agents

The capacity to inhibit other microorganisms

What are the kinds of Antimicrobial agents?

The capacity to kill other microorganisms

Give examples of Nucleic acid inhibitors

This kind of Antimicrobial agents are the most selective antibiotics with a high therapeutic index. Inhibits the transpeptidase enzymes in which cell growth stops and the death of the cells occurs.

These are chemical substances produced by microorganisms with the capacity to inhibit or kill other microorganisms.

They are effective against a limited number of pathogens. Example: Bacitracin, clindamycin, erythromycin, gentamicin, penicillin and Vancomycin

Give an example of Cell membrane inhibitors

Give examples of Cell wall inhibitors

Give examples of Essential metabolite inhibitors

They destroy different kinds of organisms. Example: Ampicillin, cephalosporins, chloramphenicol, ciprofloxacin, rifampicin, trimethoprim and tetracycline.

Give examples of Protein synthesis inhibitors.

It is the kind of Antimicrobial agent that binds with a 30S subunit that result in the misreading of mRNA and 50S subunit that results in the inhibition of peptidyl transferase and peptide chain elongation.

This type of Antimicrobial drugs are produced by bacteria or fungi. Ex.: Erythromycin, amphotericin B, vancomycin, tetracycline, penicillin

It inhabits RNA polymerase.

It inhibits the synthesis of peptidoglycan precursors.

It interferes with DNA gyarase and topoisomerase IV and highly effective for enteric bacteria.

This type of Antimicrobial drugs are modified drugs with added chemical groups. Ex.: Ampicillin, carbenicillin and methicillin.

This type of Antibacterial drugs are chemically --produced drugs. Ex.: Sulfonamides, trimethoprim, ciprofloxacin, isoniazid.

It disrupts DNA and is effectice against anaerobic bacteria.

It inhibits transpeptidation.

Gram- negatige bacteria (P. aeuruginosa) also used as a topical antibiotic.

This type of bacteriostatic agent usually kill or destroy organisms and are used for the treatment of life-threatening infections. Ex. Aminoglycosides, B-lactams, Glycopeptide

It acts on growing cells and can either be a bactericidal or bactetiostatic agent.

It inhibits the translocation and elongation of peptidoglycan.

It inhibits folic acid and metabolism and has a higher therapeutic index.

This type of bacteriostatic agent inhibit the bacterial growth but generally they do not kill the microorganisms. Ex. Chloramphenicol, erythromycin, clindamycin

It blocks the initial step in protein synthesis.

It interferes with folic acid sythesis.

What are the Characteristics of Antimicrobial agents?

They are genetic elements that are capable of integrating genes(cassettes) by an integrin encoded site-specific recombinase.

It blocks the tetrahydrofale synthesis.

It is the lowest concentration of a drug that can still inhibit bacterial growth.

It is the lowest concentration of a drug that can kill bacteria.

They are enzymes (transpeptidase or transglycolase) that mediate peptidoglycan cross-linking with reduced affinity for B-lactam antibiotics.

It is the ratio of the toxic dose to the therapeutic dose and as such, the higher the therapeutic index, the more effective the chemotherapeutic agent.

These are DNA elements that encode transposition and excision functions and which are also able to carry antibiotic resistance genes among plasmids and chromosomes.
