Benzimidazoles are a group of antiinfective anthelmintics used for various diseases in cattle such as roundworms, lungworm and infections with Giardia spp, Tritrichomonas spp and Trypanosoma spp infections.
Once the drug enters the parasite it becomes activated by the reduction of the nitro group and binds covalently to DNA molecules, resulting in irreversible helical damage and death of the organism. Drug resistance in cattle strongyles to anthelmintics is rarely described
