State vet confirms brucellosis in Sublette County cattle

(Sublette, County, Wyo.) - Dr. Jim Logan, the State of Wyoming Veterinarian, confirmed yesterday that cattle in Sublette County have tested positive for brucellosis. Brucellosis is an infectious disease that can cause cattle to abort their fetus or cause premature calving of recently infected animals, most often between the fifth and eight month of pregnancy. "In the current case in Sublette county, there are 11 infected cows out of around 500, so it is a very small percentage which indicates that the infection likely occurred recently and before there was significant spread within the herd," said Dr. Logan. "None of the adjacent or contact herds are infected." According to Dr. Logan, this is the first time since 2008 that there has been a case in Sublette county. Prior to that Wyoming had a case in 2003. The last case in Wyoming was in Park county in 2010 and 2011. "It isn't totally common to have cases of Brucellosis in Wyoming, but we have only had 11 case since 1988," said Dr. Logan. "All cases have been proven to have wild elk as the source of the infection." The cows that tested positive were taken to the Wyoming State Veterinary Laboratory to be necropsied and have diagnostic research done on the affected tissues. "When infected cattle are found in a herd, it is Wyoming rule and also federal (USDA APHIS) rule that they are removed from the herd and that all remaining herd mates must be tested negative on three consecutive whole herd tests to be released from the state quarantine," he added. *Feature Photo: Cattle heard via Creative Commons / Pitchengine Communities* #buckrail #news
