Are antibiotics chemotherapeutic agents?
In this chapter the word antibiotic refers to both synthetic compounds (antimicrobial chemotherapeutic agents) and naturally produced agents (antibiotics). These substances have selective toxicity against many living agents pathogenic to man.
What are chemotherapeutic agents antimicrobial agents and antibiotics?
Chemotherapeutic agents (synthetic antibiotics): antimicrobial agents of synthetic origin useful in the treatment of microbial or viral disease. Examples are sulfonilamides, isoniazid, ethambutol, AZT, nalidixic acid and chloramphenicol.
What characteristics makes a chemotherapeutic agent an antibiotic?
The ideal antimicrobial agent should he nontoxic to the host (selective toxicity), non-allergenic, soluble in body fluids, able to be maintained at therapeutic levels, have a low probability of eliciting resistance, long shelf life, and low cost.
What do you mean by chemotherapeutic agent?
Chemotherapeutic agents, also referred to as antineoplastic agents, are used to directly or indirectly inhibit the uncontrolled growth and proliferation of cancer cells. They are classified according to their mechanism of action and include. alkylating agents.
What are antibiotics in science?
Antibiotics are chemicals that kill or inhibit the growth of bacteria and are used to treat bacterial infections. They are produced in nature by soil bacteria and fungi.
How do antibiotics and chemotherapeutic agents serve to control microorganisms?
An antibiotic is a metabolic product produced by one microorganism that inhibits or kills other microorganisms. Synthetic chemicals that can be used therapeutically. An agent that is cidal in action kills microorganisms. An agent that is static in action inhibits the growth of microorganisms.
What are characteristics of chemotherapy?
Chemotherapy works by stopping or slowing the growth of cancer cells, which grow and divide quickly….Chemotherapy characteristics
- Make a tumor smaller before surgery or radiation therapy.
- Destroy cancer cells that may remain after surgery or radiation therapy.
- Help radiation therapy and biological therapy work better.
What class of antibiotic is cotrimoxazole?

Corticosteroids. Corticosteroids, often simply called steroids, are natural hormones and hormone-like drugs that are useful in the treatment of many types of cancer, as well as other illnesses. When these drugs are used as part of cancer treatment, they are considered chemotherapy drugs.
How are antibiotics produced by microorganisms?
Industrial microbiology can be used to produce antibiotics via the process of fermentation, where the source microorganism is grown in large containers (100,000–150,000 liters or more) containing a liquid growth medium. Oxygen concentration, temperature, pH and nutrient are closely controlled.
