Özet
Bu araştırma, doğal olarak Theileria annulata ile infekte olan Holstein sığırlarda bazı hematolojik ve hemostatik parametrelerin belirlenmesi amacıyla yapıldı. Kontrol grubu ile karşılaştırıldığında, enfekte grupta alyuvar sayısı, hematokrit değer, hemoglobin mikratı, ortalama alyuvar hemoglobin konsantrasyonu, akyuvar sayısı, lenfosit, nötrofil, monosit, eozinofil ve bazofil sayılan önemli düşüşler gösterirken belirgin bir retikülositozis ile birlikte ortalama alyuvar hacminde ciddi artışlar görüldü. Kontrol grubu ile karşılaştırıldığında, enfekte grupda aktive edilmiş parsiyel tromboplastin zamanı ve protrombin zamanında önemli derecede uzama, trombosit sayısında önemli oranda düşme, fibrinojen konsantrasyonunda ise hafif bir yükselme bulundu. Sonuç olarak; Tropikal theileriosisin, sığırların hematolojik ve hemostatik profilinde önemli düzeyde değişikliklere sebep olduğu belirlendi.
This study was conducted to measure selected haematological parameters in Holstein cattle naturally infected with Theileria annulata. Haematological analysis indicated significant decreases in red blood cell count, haematocrit value, haemoglobin amount, mean corpuscular haemoglobin concentration, and white blood cell, lymphocyte, neutrophil, monocyte, eosinophil, and basophil counts. On the other hand, significant increases were seen in mean corpuscular volume and marked reticulocytosis in infected animals compared to the animals in the control (uninfected) group. In the coagulation profile, activated partial thromboplastin time and prothrombin time were significantly prolonged, and platelet counts were significantly less in the infected group compared to those in the control group. Fibrinogen concentration was slightly higher in the infected group than that in the control group. These observations revealed that T. annulata infection in cattle is associated with marked changes in haematological and coagulation parameters.
