Answer:
Antibiotics produced by microbes are
regarded as one of the most significant discoveries of the twentieth century
and have greatly contributed towards the welfare of the human society.
Anti is a Gk. word that means 'against'
and bid means 'life', together they mean 'against life'(in the context of
disease causing organisms); whereas with reference to human beings, they are
'pro life' and not against. Antibiotics are chemical substances, which are
produced by some microbes and can kill or retard the growth of other
(disease-causing) microbes.
Antibiotics have greatly
improved our capacity to treat deadly diseases such as plague, whooping cough
(Kali khansi), diphtheria (Gal ghotu) and leprosy (Kushtrog), which had
killed millions all over the
globe. Today, we cannot imagine a world without antibiotics.
