Antibiotics: Their application in veterinary practice

Abstract

Extract

Antibiosis was recognized by Pasteur and his co-workers about seventy years ago (Lawrence and Francis, 1953). Many fungi and bacteria possess this power. It has been generally accepted that an antibiotic is a substance, produced by a living micro-organism, which has the ability to inhibit the growth of another. In this paper, the use of antibiotics in growth promotion and in semen preservation is not considered, neither are the sulphonamides except for comparative purposes.
