Abstract The term antibiotic originally referred to any agent with biological activity against living organisms; however, ‗‗antibiotic‖ now refers to substances with anti-bacterial, anti-fungal, or anti-parasitical activity. There are currently about 250 different chemical entities registered for use in medicine and veterinary medicine (Kümmerer and Henninger, 2003). |
