Sero-epidemiologic survey of the equine rhinopneumonitis in the region of Khenchela (Algeria)

The aim of this study is to evaluate the prevalence of respiratory infections of viral origin in equines. In this perspective we have researched antiviruses antibodies in equine’s rhinopnemonitis in 210 horses of different breeds, Arabian purebred,Thoroughbred, arab barb and barb, all stationed in the region of Khenchela, located in the north east of Constantine. These animals are prealably recognised, upon a clinical exam, in a good health. They have received a diet containing barley and hay. They are of different sexe and their age is varying between 2 and 7 years old. The equines play an important socioeconomic role. In several rural areas, equines are regularly used as a tensile force for the animal traction cultivation and transport of persons and goods. They thus contribute widely to the increase of agricultural production and the improvement of socio economic conditions of rural populations. These results demonstrate that among the 210 serums tested, 5 were positive to the reaction of complement fixation. These results are discussed in relation with those observed by other authors.
