TSE transmission results by the oral versus the intra-cerebral route in TgOvPrP4 ovine transgenic mice.

Survival periods (means +/− standard deviations) and the number of analyzed mice for the ten TSE sources are shown together with the results of PrPres detection in brain and spleen (number of PrPres positive mice/number of mice examined). The results obtained for the second intra-cerebral passage (2nd i.c.) are shown in comparison with those obtained for the third passage by the oral route (3rd oral) or the intra-cerebral route (3rd i.c.). ND: no data.
