[QUOTE="Lucky_P, post: 1391758, member: 12607"] It's a bacterium, not a virus. And yes, we've long known that it can cross the placenta to infect unborn fetuses in infected cows. R.Sweeney and associates at U.Penn, back in the 1980s, followed infected, high-shedding animals to slaughter and collected fetal tissues. They were able to isolate MAP from about 25% of those fetuses. So... we routinely expect that daughters(or sons) born to infected cows are about 10 times more likely to be infected than a calf born to a noninfected dam in the same herd - whether by in utero exposure, oral exposure through organisms spread in milk/colostrum, or the constant exposure to organisms spread in the infected dam's feces. Lots of good information at the UofWI page here: johnes.org [/QUOTE]
