Cefazolin

Cefazolin (also known as cefazoline or cephazolin) is a semi-synthetic first-generation injectable cephalosporin. Cefazolin has broad-spectrum antibiotic action due to inhibition of bacterial cell wall synthesis. It is more likely to be prescribed for chickens with serious skin and soft tissue infections
but is used for the treatment of a number of bacterial infections in poultry, especially against those caused by staphylococci and streptococci species of Gram positive bacteria.

Note: Cephalosporins may disturb the normal intestinal microflora of poultry, particularly when administered orally and at high doses.
