Abstract
The Toxocarosis is a common zoonotic parasitic infection caused by three etiological agents T. cati, T. canis and T. vitulorum. It has a severe impact on health and economy especially in countries where it is endemic. The study was conducted from June 2013–2014. The blood samples were collected from (n = 270) cattle grazing in the Potohar region. The sera were separated and subjected to anti-Toxocara ELISA and results revealed an overall seroprevalence of 16.67% (45/270) in cattle. The relationship between age groups and seroprevalence of T. vitulorum indicated a statistically significant difference (p = .01, χ2 = 16.81) and non-significant was sex group of cattle and seroprevalence of T. vitulorum (p = .859, χ2 = 0.032). The results also revealed a statistically non-significant difference between cattle breed and Toxocara infection (p = .142, χ2 = 5.424). From the study, we concluded that indirect ELISA is a highly efficient assay for timely diagnosis of infection in order to adapt control strategies to mitigate the infection. The present study recommended the need to develop ELISA by using excretory-secretory (ES) T. vitulorum antigen in order to reduce the cost of commercial kits for mass screening purposes. Furthermore, the result of the current study also suggested and conducting similar nature of studies in other agroecological zones of Pakistan, which will help to provide baseline epidemiological data of parasitic diseases.
