Question

Antibiotics kill or inhibit bacteria. The real revolution in antibacterial therapy began with the discovery of Alexander Fleming. Antibiotics have either bactericidal effect or a bacteriostatic effect on microbes. The broad spectrum antibiotic is/are:

• A. vancomycin
• B. ofloxacin
• C. chloramphenicol
• D. All

Answer 1

The correct option is D All

Antibiotics which kill or inhibit a wide range of Gram-positive and Gram-negative bacteria are said to be broad spectrum antibiotics.
Chloramphenicol, isolated in 1947, is a broad spectrum antibiotic. It is rapidly absorbed from the gastrointestinal tract and hence, can be given orally in case of typhoid, dysentery, acute fever, certain form of urinary infections, meningitis and pneumonia. Vancomycin and ofloxacin are the other important broad spectrum antibiotics.
