Abstract
The objective of the present study were to evaluate hemogram, acute phase
response, acid base balance and blood gas analysis in newborn calves infected with
Theileria annulata . The study was conducted on 55 local newborn calves (male and
female), 1-9 days old. The study was carried out in Mosul , Iraq. Forty five newborn
calves were infected with Theileria annulata. and Ten clinically normal calves served
as controls. Diseased calves showed sings of fever ,unilateral or bilateral visible
swelling of superficial lymph nodes. pronounced upward bulging of temporal fossa,
outward bulge of conjunctivae with exophthalmos, paleness and/or icteric mucus
membranes with petechial hemorrhages on the conjunctiva, lacrimation, dyspnea and
depression. There was a significant reduction in the mean values of erythrocytes
count, Hb and PCV,in diseased newborn calves infected with Theileria annulata and
anemia was of Macrocytic hypochromic type. The percentage of hemoparasitism
(parasitemia) ranged between (3-18%) with a mean of (11.88%). Results also
indicated significant increase in total leukocytes count as results of significant
increase lymphocytes. Diagnosis of Theileriosis were confirmed by microscopical
examination of Giemsa stained lymph node aspirate and peripheral blood smears.
Results were also showed significant decrease in blood pH,Pco2,Bicarbonate, Base
access and Oxygen saturation percent(So2) ,However significant increase in Anion
gab was found and Titritional metabolic acidosis were indicated. Moreover results
show significant decrease in haptoglobin and fibrinogen in diseased newborns calves
than in controls.It have been concluded that Theileria annulata infection in newborn
calves resulting in serious effects and health deterioration, leading to substantial
significant economic losses
