2016, Microbial PathogenesisCitation Excerpt :Transplacental or congenital transmission is the most frequent and severe form of transmission, with natural spread in the acute or acute relapse of chronic disease during pregnancy [27]; thus, the disease spread is inevitable in flocks with the presence of positive animals. Duncanson et al. [28], while detecting T. gondii DNA from aborted lambs of a commercial sheep flock, found high levels (94%) of transplacental transmission. In lambs born alive, 42% were seropositives for T. gondii, which represents lower levels compared to those found in this study (68%).
