Clinical and laboratory studies on theileriosis outbreaks in Sicily, Italy.
A total of 153 blood samples were collected all over the Sicilian island in 15 farms. 29.4% and 25.5% were PCR positive for Theileria annulata and T. buffeli/orientalis respectively. 15.7% of cattle blood samples showed a mixed infection with both Theileria species. Each farm showed an infection rate ranging from 0% to 100%. Hyalomma marginatum and Boophilus annulatus were the most common ticks collected in April and November 1998 respectively. The aim of the present work was to investigate on haemoparasite species spread in Sicily. Ticks vectors involved in the transmission, distribution, risk areas and seasons, state of healthy carrier, are also discussed in this paper.
