Identification and chemotherapy of ectoparasites of camels (Camelus dromedarius) in Dera Ghazi Khan
2005
Iqbal, M.
300 camels were examined during the period October to November 2004. Out of 300 camels 109 (36.3%) were found infested with ecto-parasites. Two types of ecto-parasites were found to be active during those days. Sixty-three camels were infested with ticks. After collection these ticks were mounted for identification, with the help of their morphological characters. The only tick found to be identified was Hyalomma dromedarii and the tick infestation was found to be 21% in those areas during October-November 2004. Similarly, 85 suspected camels were examined by skin scraping in the District Veterinary Diagnostic Laboratory, Dera Ghazi Khan, for identification of mites 46 camels were found to be infested with mange mites and the mange mite's infestation was 15.3%. The species of mites identified was Sarcoptes scabiei var. cameli. For chemotherapeutic trails 60 positive ecto-parasitic camels were divided into 3 groups i.e. A, B and C, 20 camels in each group. For further procedures these groups were divided into sub-groups i.e. A (A1 + A2), B (B1 + B2) and C (C1 + C2) where each sub-group contained 10 animals (camels). A1, B1 and C1 were infested with mites and A2, B2 and C2 with ticks. The group A was treated with Ivermectin (Baymec; Bayer) at dose rate of 1 ml/50 kg body weight sub/cut. Similarly the group B was treated with Neguvon (0.15%) solution with spray machine. Where, the group C acted as infected, non-medicated control group. The efficacy of Baymec on 7th day was 75% and on 14th day was 80%. But the efficacy of Neguvon (0.15% solution) on 7th day was 65% and on 14th day was 75%. The camels of group C were not treated and acted as control.
