Distribution of onchocercosis in horses caused by Onchocerca cervicalis Rail-liet et Henry, 1910 and O. reticulata Diesing, 1841, in the region of East Caucasus
Abstract
Distribution of onchocercosis in the conditions of East Caucasus is studied by the method of dermolarvoscopy of 199 horses and helminthological autopsy of a cervical sheaf and sinews of extremities of 118 horses. Onchocercosis is wide dis-tributed in Chechen Republic. The extensity of infection of horses with Onchocerca spp. on areas fluctuates from 23,0 to 41,6 % that, on average, makes 32,66 % at detection in 100 mg of skin of 95,2–181,4 expl. of microfilariae. Extensiveness of the infection caused by Onchocerca cervicalis, O. reticulatа and both types made respectively 25,42 %, 5,93 and 2,54 %. The maximum contamination of horses is noted in foothill zone. Contamination of horses with age considerably raises. Max-imum contamination is established in horses at the age of 6–8 years. It is noted dif-ferences in age dynamics of horses infection with O. cervicalis and O. reticulatа.
