Efficacy of Closantel Plus Albendazole Liquid Suspension against Natural Infection of Gastrointestinal Parasites in Jordanian Camels

Oral administration of closantel in a dose of 10 mg/kg plus albendazole in a dose of 5mg/kg liquid suspension was studied in 75 camels naturally infected with various types of gastrointestinal parasites. The camels involved were 15 pregnant she-camels, 20 nonpregnant she-camels and 40 male camels of various ages. Each camel received a single oral dose of closantel (10 mg/kg) plus albendazole (15 mg/kg) orally. Two weeks later, 20 camels of this group were redosed again with the same dose of the anthelmintic. Fecal samples were collected from the rectum of all the camels at the time of treatment and again 14 and 42 days post treatment. Fecal egg counts and generic determination of third stage larvae was performed. Results indicated that six different species of gastrointestinal tract parasites were identified in camels. A single treatment of closental plus albendazole mixture reduced egg counts in camels by 100%, 99%, 98% and 77% for H. longistipes, Ascaris spp., Monezia expansa and Fasciola hepatica, respectively. However, administration of the drug twice, two weeks apart, significantly raised the efficacy of the drug for clearance of the parasites from 92.5% to 100% in camels affected with various parasites. Camels were not adversely affected by treatment.
