title: [Molecular diagnostic of congenital babesiosis in neonates foals from State of Rio de Janeiro, Brazil].
abstract: The aim of this study was to demonstrate, through nested PCR (nPCR) method, the occurrence of congenital babesiosis in two foals born of carrier mares. All mares were positive for T. equi based in visualization of intraerytrocytic parasites in blood smears, in indirect fluorescent antibody test (IFAT) and nPCR reactions. Just one mare was nPCR-positive for B. caballi. After the birth, all foals presented nPCR-positive for T. equi, while just one foal presented nPCR-positive for B. caballi. The present study prove the occurrence of congenital babesiosis in new-born foals, however, new studies are necessary to elucidate if the infection occur for transplacental transmission or in parturition moment.
