[QUOTE="Lucky_P, post: 1834678, member: 12607"] No. Animals (cattle, humans, horses, etc.) do not become 'immune' or 'resistant' to antibiotics/antimicrobials. But... using subtherapeutic levels of those drugs can select for populations of bacteria that have genes that code for resistance to antimicrobials. All the 'susceptible' 'bugs' are killed off, and the ones that have genes for resistance are left to give rise to subsequent generations. [/QUOTE]
