Cefalonium is a 1st generation cephalosporin with a broad spectrum of actvity against Gram-positive and Gram-negative bacterias. The drug inhibits the bacterial cell wall synthesis by binding to penicillin binding proteins. Cefalonium is approved for routine dry cow therapy to treat existing sub-clinical infections and to prevent new infections which occur during the dry period.
