The images tke a little while to load. Alan Beat's summing up of the article: " the gist of this article is that, on a farm where numbers of sheep intermingled with each other over a period of several months following exposure to FMD, with ample opportunity for disease transmission, only eight individuals out of (two) hundred were found to have antibodies on testing. In other words, the disease had not spread through the flock, but had fizzled out. This is the usual, and expected, occurrence in sheep flocks and has been shown in laboratory experiments many times over, including those carried out here in the UK at IAH Pirbright."
