Abstract: | Limited data is available on the vertical transmission of Neospora caninum via the colostrum. The results of our previous research revealed the presence of N. caninum DNA in the milk of seropositive cows. The aim of the present work is to demonstrate parasite DNA in colostrum samples. A
polymerase chain reaction using Np21 and Np6 primers was applied to DNA isolated from the colostrum sediment in order to amplify
the corresponding genomic Nc-5 region. The expected 328-bp product was obtained in colostrum samples collected both on the
calving day and the day after. This is the first detection of N. caninum DNA in the colostrum of seropositive cows, and these findings implicate the possibility of N. caninum transmission through the colostrum. |
