Antibiotic Drugs

Penicillin, the first antibiotic compounds used in modern medicine is developed by fungi of the genus penicillium. Bacteria of the genus Streptomyces is used to produce the streptomycin. With thee advancement in organic chemistry, we are able to formulate many antibiotics by chemical synthesis, such as the sulfa products. The efficiency of antibiotics depends upon following:

• The site of the infection
• The ability of the antibiotic to reach the infection spot
• The capability of the microbe to inactivate or expel the antibiotic

Some anti-bacterial antibiotics destroy bacteria (bactericidal) while others inhibit bacteria from multiplying.
