Submitted by: agcomm, Thu Dec 18 12:35:24 1997 December 18, 1997 Rabies Threat Continues in Region Rabies in livestock can be a problem, experts say. In fact, at least one person has been exposed to rabies by rabid cows since Nov. 1 in North Dakota, according to the North Dakota Department of Health. The North Dakota State University Veterinary Diagnostic Laboratory has diagnosed rabies in three cows during the same time period. That's not a serious problem, but it does indicate that livestock producers and the public need to be alert to the possibility of rabies all year long, according to Charlie Stoltenow, veterinarian with the NDSU Extension Service. "These cows came off pasture and were having difficulty chewing and swallowing," Stoltenow says. "I'm sure the producers thought they were choking and went looking for the obstruction." In cattle, rabies affects the ability to swallow and to bring up the cud for chewing. Infected cattle have a characteristic bellow, sometimes stagger and exhibit unusual behavior ranging from extreme excitement to depression. The rabies virus is spread in the saliva and can be transmitted through any opening in the skin--even those too small to see. "On the range, these cattle would die without a diagnosis, but as cattle are moving back into handling and holding facilities for the winter, producers may notice symptoms sooner," he says. That's a good time to call the veterinarian. Stoltenow says he suspects most infected cattle get rabies from skunks. "You have a skunk wandering around during the daytime, and cattle, being naturally curious, will approach the skunk. The skunk looks up, and the first thing it sees is this big fleshy nose--a perfect place to bite," Stoltenow explains. This year 51 skunks have been submitted to the NDSU Veterinary Diagnostic Laboratory for testing, and 44, almost 90 percent, were rabid. "If you see a skunk, it's probably best to assume it has rabies," Stoltenow says. Eliminating skunks and other vermin around the house and farmyard is a good precaution against rabies, he says. "Other common carriers of rabies include cats and dogs," Stoltenow says. "It's very important to have pets on the farm or ranch vaccinated. Everybody thinks of dogs when you talk about rabies, but cats are an important carrier too." Rabies is incurable and fatal to humans, Stoltenow notes. Last year three people died of rabies in the United States. The only treatment is a series of shots that prompts the body to build up the body's own immunity quickly, before the virus has a chance to multiply and affect its victim. That's why it's important to learn quickly if you've been exposed to rabies. The vaccinations are effective, but expensive, costing up to $1,000. Veterinarians and others who may be exposed to rabies frequently receive a vaccine that provides long-term protection against the virus. ### NDSU Agriculture Communication Source: Charlie Stoltenow (701) 231-7522 Editor: Tom Jirik (701) 231-9629
