16.9 What is meant by the term ‘broad-spectrum antibiotics’? Explain.


Antibiotics that are effective against a wide range of gram-positive and gram-negative bacteria are known as broad-spectrum antibiotics. Chloramphenicol is a broad-spectrum antibiotic. 

 

It can be used for the treatment of typhoid, dysentery, acute fever, pneumonia, meningitis, and certain forms of urinary infections. Two other broad-spectrum antibiotics are vancomycin and ofloxacin. Ampicillin and amoxicillin −synthetically modified from penicillin − are also broad-spectrum antibiotics.
