Babesia caballi and Theileria equi are the causative agents of equine piroplasmosis. In this epidemiological study, 294 horses reared in a rural area of northern Italy were studied. During January 2008-January 2009, blood samples were taken for serology (indirect fluorescent antibody test) and for polymerase chain reaction (PCR). Data on the geographical area, sex, and age were collected for statistical analysis of risk factors associated with infection. A seroprevalence of 8.5% was found: 8.2% of the animals were positive for anti-T. equi antibodies and 0.3% for anti-B. caballi antibodies. No dual infections were observed. Of those horses with positive serology to T. equi, 33% were also positive in PCR, whereas none of the seropositive horses for B. caballi was positive in PCR. No significant correlation between sex or age was found for infection status.

Abstract
Babesia caballi and Theileria equi are the causative agents of equine piroplasmosis. In this epidemiological study, 294 horses reared in a rural area of northern Italy were studied. During January 2008-January 2009, blood samples were taken for serology (indirect fluorescent antibody test) and for polymerase chain reaction (PCR). Data on the geographical area, sex, and age were collected for statistical analysis of risk factors associated with infection. A seroprevalence of 8.5% was found: 8.2% of the animals were positive for anti-T. equi antibodies and 0.3% for anti-B. caballi antibodies. No dual infections were observed. Of those horses with positive serology to T. equi, 33% were also positive in PCR, whereas none of the seropositive horses for B. caballi was positive in PCR. No significant correlation between sex or age was found for infection status.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
