Attenuation effect of UV on Haemonchus contortus Larvae in Experimentally Infected Goats
Journal Title: Journal of Veterinary Medical Research - Year 2013, Vol 22, Issue 1
Abstract
This study was conducted to study the UV protective effect against Haemonchus contortus infection in goats. Sixteen male goats were divided into 5 groups, control infected, control uninfected and UV 30minutes; UV 60minutes and UV booster 60minutes exposure. The UV groups were exposed to UV irradiation at wave length 254nm for 30 and 60 minutes. The UV booster 60min was administrated 2 doses of exposed larvae with an interval of one month. All groups except the control negative one were challenged for 42 days from the beginning. In UV booster 60min had reduction in egg count per gram feces and worm burden (93% & 34 % respectively). These parameters were similar in control infected, UV 30min and UV 60min groups. Increases in levels of antibodies were found in goats of UV booster 60min group the other groups. Finally, 2 doses of UV 60min exposure could protect goats from H. contortus.
