INOCULATION OF COWS.

Intrauterine Neospora caninum inoculation of heifers and cows using contaminated semen with different numbers of tachyzoites.

OBJECTIVE To investigate the potential of different Neospora caninum tachyzoite doses to infect heifers (experiment 1) and cows (experiment 2) when administered in utero by artificial insemination via contaminated semen. METHODS In experiment 1, five groups of 5, 7, 8, 9, and 5 cyclic heifers were hormonally synchronized and artificially inseminated with semen containing 0 (A, controls), 10(2...

Congenital abnormalities in newborn calves after inoculation of pregnant cows with Akabane virus.

A fresh isolate of Akabane virus was inoculated intravenously into 11 seronegative pregnant cows at 62 to 96 days of gestation. Two of the cows were slaughtered 18 days post-inoculation, and the fetuses were examined; the remaining cows were allowed to give birth. All the inoculated cows developed viremia and neutralizing antibody for the virus, indicating that the cows were actually infected w...

the efficacy of that procedure in the way which had been commended, for such purposes, in my evidence to the Plague Commission of 1898-99, and in which I had been testing curative treatments in India. The experiment on that occasion was not completed by them, and although the preliminary statement which they made oil the results was favourable to the therapy, they did not persevere with the stu...

The origins of inoculation.
