Objective: This study was carried out in order prevalence of
Theiler a infection and interrelatinship with clinical sign in sheep.
Design :Field study. Animals: Three hundred sheep.
Procedure: During summer season (2000) , 300 sheep were examined clinically and paraclinically at Ghaemshahr abattior. Before slaughter, body temperature, heart rate and respiratory rate of sheep were taken and inspection of lymph nodes and color of mucouse membrane (eye and vagina) were also assessed. All parts
of body surface were inspected for presence of tick and some of
them were collected. Smears of periphereal blood were prepared
frome car. All of smears were fixed with methanol and stained with Gimsa.
Statistical analysis: Results from this study were analysed with Student “t” test and Chi-square. Results: Out of 300 sheep the prepared blood smear showed that
39(13°/) sheep infected with Theileria. 3 1(10.3%) sheep infected with tick (30 1-Ivaloma anatolicurn anatolicum and I Ripycephalus bursa). Clinical examination showed that heart rate, respiratory
rate, lymph nodes and color of mucous membrane (eye and vagina)
in all of sheep were in normal range and one case suffered from
enlargement of right prescapular lymph node. There was no
significantly difference between two groups (infected and nonifected
sheep). Body temperature was significantly higher in infected group (P<0.05). Conclusion: Since none of infected sheep in this study showed the clinical sings of theileriosis, it seems that these sheep had been probably infected with Theileria ovis or had been infected with
Theileria hirci perior and were carriers at the time of study. J. Fee.
