Parasitism of diferent strongylid nematodes belonging to the families Trichostrongylidae, Strongylidae and Ancylostomidae on sheep, are widespread in all regions of animal breeding, but especially in areas with a humid climate. As they result in drastic decreases in production of adult animals and growing delays in young animals, imposing costly prophylaxis measures, these parasitic diseases have a significant economic impact. While studies in helminthology are directed towards more in-depth perspectives, such as DNA modifications of parasites, the continuous monitoring of occurrence and prevalence of these parasitic species remains important. In addition, because there are few reports on gastrointestinal parasites of ruminants and especially of sheep in our country, the present study aims at investigating the occurrence of strongyle infections in sheep, in Southern Romania. For this, a coproparasitological study was carried out on a total number of 424 sheep, out of a population of 3256 animals, originating from six farms from this region. A flotation technique was used to detect helminth eggs; however, protozoa oocysts, when detected, were also registered; additionally a Baermann method, for detection of lungworm larvae was performed. The findings indicate the following infections, as follows: strongyles 65.1%; Moniezia spp. 18.9%; Eimeria spp. 14.4%; Protostrongylidae 7.1%, Dictyocaulus filaria 2.1%. The findings highlight the high occurrence of strongyle infections, but also of other parasitic species with significant impact on the both animal health and their productivity and highlight the importance of a proper parasitological control to be applied in sheep farms.
