Correlation between hematological profile and theileriosis in Bali cattle from Muara Bulian, Jambi, Indonesia

Abstract

Background and Aim: Theileriosis is a parasitic disease caused by the hemoprotozoan Theileria spp. The main transmission route of this disease is through tick vector bite. Theileriosis causes economic losses in livestock such as Bali cattle. This study aims to analyze the prevalence of theileriosis and its correlation with the hematological profile of Bali cattle from the subdistrict of Muara Bulian, Batang Hari, Jambi, Indonesia. Materials and Methods: Ninety-four blood samples were collected through jugular vein of Bali cattle. The presence of Theileria spp. was determined using blood smear. Routine blood tests and double-staining immunohistochemistry against CD4+ and CD8+ lymphocytes were conducted on all blood samples. Results: A total of 34.04% of the samples were infected by Theileria spp. Theileriosis affected only hemoglobin level (p0.05). However, it also decreased CD4+ and CD4+/CD8+ ratio (p<0.05), besides increasing CD8+ (p<0.05). Conclusion: Theileriosis does not change the hematological profile of Bali cattle except for the hemoglobin levels. Moreover, it promotes T-cell depletion.
