Distribution of Toxocara vitulorum in Cattle of Ağrı Region

Abstract

Objective: Parasitizing in the small intestines of cattle, buffalo and bison, Toxocara vitulorum is seen in countries with humid tropical and subtropical climates, including Türkiye. Adult parasites can cause digestive disorders such as loss of appetite, weakness, diarrhea or constipation, and sometimes death, especially in calves. This study was planned to investigate the distribution of T. vitulorum in cattle of the Ağrı region.

Methods: In this study, stool samples of the size of a walnut were taken from the rectum of 200 calves 0-6 months old and 200 cattle older than 1 year in the province of Ağrı and its districts, and the preparations were prepared using the saturated zinc sulfate flotation method and the preparations were examined under a light microscope.

Results: T. vitulorum eggs were detected in 70 (35%) of 200 calves aged 0-6 months and 21 (10.5%) of 200 cattle over one year old. The difference in positivity between cattle over one year old and calves was statistically significant (p=0.001). With fecal examination ın 22 of the calves (11%), Trichostrongylidae spp. eggs were detected.

Conclusion: It was determined that the prevalence of T. vitulorum in calves was high in Diyadin, Eleşkirt, Doğubayazıt, Hamur, Taşlıçay, Tutak and Patnos districts of Ağrı province. We believe that larger-scale studies should be conducted on the spread of this parasite, which causes significant low yields in cattle breeding.
