**8.6 Treatment and control**

Infected sheep and goats can be treated with fenbendazole (5-10 mg /kg) for 3 days (Navarre and Pugh, 2002). Fenbendazole (10 mg /kg BW daily for 3 days) and albendazole (20 mg /kg BW daily for 3 days), have been shown also to be effective in calves (Thompson, 2004; Radostits et al., 2008). Geurden et al., (2006), demonstrated the efficacy and safety of a 5 day treatment with paromomycin against an experimental Giardia infection in calves. Ozmen et al., (2006), suggested that five day treatment with Trimethoprim + Sulfodoxine and multivitamin complexes can be effective in the prevention and treatment of Giardia intestinalis in lambs and kids.

Re-infection frequently occurs if the sources of contamination are not eliminated and the frequency of transmission is high (Thompson, 2004).
