College of Agriculture and Natural Resources scientists at the University of Wyoming are hopeful their brucellosis studies may produce a better vaccine for livestock and are studying whether a change in vaccination procedures could offer better control.

Brucellosis can cause elk, bison and cattle to abort fetuses. The highest risk of brucellosis transmission to other animals occurs after an animal has an abortion. The organism can also be transmitted to humans, often through consumption of unpasteurized milk or dairy products such as soft cheese, which may result in a severe disease called undulant fever.

Brucellosis is an exotic disease that came from Europe and European cattle and was then transmitted to wildlife in the U.S., establishing the reservoir in elk and bison seen in the Greater YellowstoneArea.

“We have eradicated the disease from livestock but occasionally get a disease spillover from elk transmitting the organism to livestock,” said Bruce Hoar, University of Wyoming brucellosis research coordinator. “One of the ways we try to control brucellosis is through the use of vaccinations.”

Scientists are interested in pursuing vaccines for wildlife, particularly elk; existing vaccines for cattle are not very effective at preventing disease in elk. The emphasis, though, is on livestock vaccines, said Hoar.

Cattle in the U.S. have been vaccinated since the 1930s with a vaccine called Strain 19. That vaccine was moderately effective preventing 60-70 percent of cattle from aborting after becoming infected, said Hoar. Strain 19 was replaced by a vaccine called RB51 in the 1990s and is the currently licensed vaccine for cattle.

“It, too, only protects 60-70 percent of animals in the herd, so that leaves 30-40 percent of the herd vulnerable, and, because of that, we are looking for better vaccines, and that is what a team of researchers here at the University of Wyoming have been involved in for a number of years,” said Hoar.

Goshen County’s 4-H meat judging team won reserve champion in October at the American Royal competition in Kansas City, Mo.

Team member Danielle Schainost, president of Goshen Livestockers 4-H Club, and a freshman at Eastern Wyoming College, earned a perfect score on retail identification and was the contest’s overall top individual.

Michael and Mai Lee Olsen coached the four-person team. Other team members are:

·      Makenna Greenwald, president of Little Aggies 4-H Club, sophomore at Lingle-Fort Laramie High School.

·      Nelson Lewis, vice president of Goshen Livestockers 4-H Club, senior at Southeast High School.

·      Skyler Miller, president of Prairie Center 4-H Club, junior at Torrington High School.

Greenwald earned sixth-place overall individual and was champion individual in beef judging.

With a team score of 2,118, team members received various awards including the champion title in beef and total judging. They competed against teams from across the country including those from Colorado, Kansas, North Dakota, Virginia and Texas.

The team advanced to national competition by winning the Wyoming State 4-H Contest in April.

Innovative avenues in information delivery and professional expertise led to the manager of the Office of Communications and Technology in the University of Wyoming Extension receiving the organization’s Creative Excellence Recognition Award.

Tana Stith received the honor Nov. 5 during the organization’s annual training in Laramie.

Nominators cited the professionalism of the office reflected in numerous interdisciplinary and cross-campus projects. Her collaboration is friendly, energetic and goal-oriented producing a professional presence at the University of Wyoming and across Wyoming, nominators stated.

Stith, whose speciality is graphic design, was the driving force behind the 100 Years of Extension traveling display. Through photographs, articles and interactive computer displays, the presentation shows how UW Extension has responded to Wyoming citizen needs since 1914.

Stith’s expertise is reflected in her work with extension’s quarterly magazine Barnyards & Backyards, extension’s yearly publication CONNECT and the Wyoming Agricultural Experiment station’s annual research magazine Reflections and Field Days Bulletin. The UW Extension Office of Communications and Technology team has received many state and national awards for publications and video work.

Stith joined the University of Wyoming in 1988 and UW Extension in 1990.
