This study aimed to identify the presence of Trypanosoma vivax DNA in the colostrum of infected goats and to explore the possibility of transmission for neonates fed using colostrum collected from infected goats. We used twelve goats in the final third of gestation with an age of approximately 24 months. Six goats were inoculated intravenously with 0.5mL of blood containing approximately 1.25x105 trypomastigotes of T. vivax, and six remained uninfected. The presence of T. vivax in colostrum was evaluated by Polymerase Chain Reaction (PCR). The possibility of T. vivax transmission by colostrum was assessed by feeding six neonates born of serologically negative goats using colostrum from infected goats. Peripheral blood from neonates was collected daily for thirty days to assess the T. vivax presence through the examination of Giemsa-stained smears of leukocyte layers with the buffy coat technique (BCT) and by PCR. The results of a direct examination of colostrum were negative, but PCR confirmed the presence of T. vivax DNA in all infected goats. Additionally, lactogenic transmission by colostrum was not demonstrated once both BCT and PCR of neonate peripheral blood were negative.
