Amoxicillin For Chickens

Amoxicillin is a broad spectrum penicillin antibiotic used to treat certain bacterial infections in poultry. Amoxicillin has activity against penicillin-sensitive Gram-positive bacteria, as well as some Gram-negative bacteria. The gram-positive spectrum of activity includes alpha- and beta-hemolytic streptococci, some Staphylococci species, and Clostridia species. Amoxicillin is also effective against Escherichia coli (E. coli), many strains of Salmonella, and Pasteurella multocida. Amoxicillin is most commonly given to birds who were recently attacked by a predator, to help prevent pasteurellosis (fowl cholera) from bites or scratches.
