ABSTRACT<br />
EPIDEMIOLOGICAL ASPECTS OF EQUINE THEILERIOSIS AND YOUR RELATIONSHIP<br />
WITH THE TICK RHIPICEPHALUS (BOOPHILUS) MICROPLUS IN THE TWO FARMS<br />
LOCATED IN THE SOUTHERN RIO GRANDE DO SUL STATE<br />
The equine theileriosis is consi<strong>de</strong>red one of the major parasitic diseases in horses. It`s caused by<br />
infection with Theileria equi, naturally transmitted by ticks. The tick Rhipicephalus (Boophilus) microplus<br />
is the only fo<strong>un</strong>d in horses in the region and also cattle parasite. The objective of this study was to compare<br />
the inci<strong>de</strong>nce of the disease with the coexistence of cattle and horses with infestation of R. B. microplus.<br />
Used (n = 47) horses located in two different farms. In on this farm, 25 animals without contact with<br />
the cattle and the other farm, 22 animals, also created with direct contact with cattle. During one year,<br />
information was obtained as clinical signs of animals, serology equine. Theileriosis, tick infestation in<br />
these horses and climatic characteristics of the region. The positive sorology for equine theileriosis was<br />
40%, for horses do not contact with cattle and the positive serology was 90.9%, for horses that are in direct<br />
contact. Only fo<strong>un</strong>d Rhipicephalus (Boophilus) microplus in horses that are in direct contact with cattle.<br />
The importance of ticks in disease transmission its suggested that the horse represents an alternative for the<br />
tick R. B. microplus infestation occurs only when there is direct contact between horses and cattle, but also<br />
evi<strong>de</strong>nced the potential of Rhipicephalus B. microplus in the transmission of T equi in horses.<br />
Key words: Theileria equi, Direct Contact, prevalence.<br />
