| Popis: | 'Candidatus Mycoplasma haemobos' is a haemotropic mycoplasma that can produce various clinical signs in cattle, but abortive potential of the parasite is unknown, as well as the frequency of transplacental transmission in cattle. Thus, the objective of this work was to evaluate the frequency of detection of 'C. M. haemobos' in aborted fetuses and the blood of dairy cows. Blood samples of 22 dairy cows that aborted and pool tissues (brain, lung, heart and liver) of their respective aborted fetuses were tested by conventional PCR. The occurrence of 'C. M. haemobos' DNA in adult animals was 40.9% (9/22) and in the fetuses was 18.2% (4/22). Two fetuses that contained 'C. M. haemobos' DNA were derived from cows which were PCR negative. When stratifying by breed, it was observed that Jersey cows had a higher proportion of positive animals (8/11; 72.7%) as compared to Holstein (1/9; 11.1% P |
