Until recently all rabies vaccine was made much as Pasteur made it: by injecting the virus into the brains of rabbits. The vaccine that was later extracted contained rabbit-brain protein, and it was likely to set up painful local reactions. In some cases it caused paralysis or death. In 1957, Eli Lilly & Co. began marketing a vaccine made in fertilized duck eggs. Only the occasional person who is allergic to eggs will get a bad reaction from it. For dogs, a preventive vaccine made from live, though weakened, virus has proved effective. But it has been considered too risky...
...central nervous system before abdominal injections have time to build up protective antibody. Since 1954. these victims have been injected with antirabies serum from horses. This gives only short-lived, "passive" immunity, but it works fast. The trouble is that horse serum is almost as dangerous as the rabbit-brain product. Now, said Dr. Tierkel, veterinarians and others who have had a full course of vaccinations are being asked to take a booster shot of duck-egg vaccine. A month later, they donate a pint of blood. The gamma globulin fraction from the serum in these blood samples is rich...
...improve the process, Bhattacharya moved to the Max Planck Institute for Animal Breeding at Hagen, Germany, where he went to work under the direction of Zoologist Gham Gottschewski. Using rabbits, which are not only cheaper than cattle but much quicker to breed, he inseminated thousands of does with sperm that had been allowed to settle under varying conditions. His early results were not promising, but after three years of experimentation he hit on a winning combination. He mixed rabbit sperm with egg yolk and glycol, and stored the solution for twelve hours in a refrigerator at slightly above the freezing...
...except a rabbit cares much whether rabbits are male or female, but with dairy cattle, bred for their milk-producing ability, sex is a vital difference. Bhattacharya has now moved to a big cattle-breeding establishment in Schleswig-Holstein to find out whether his simple system can reduce the number of low-value male calves born to German dairy cows. Theoretically it should work the same for all mammals, including humans...
...tune and even opera (the Willow Song from Otello). Makeba can manage them all, but her heart is in the songs of her own people, like Ohude and Uyadela. "When all the beasts of the earth had gone to fetch their tails," she sings in Zulu, "the rock rabbit had long given up all hope, hence the absence of his tail...
