Looking for Anaplasmosis in Beef Cattle
Researchers at the University of Illinois are working with beef cattle producers in the southern third of the state to determine the prevalence of a disease that causes cows to become listless and die.
 
A cattle disease called anaplasmosis has been ramping up in southern Illinois, or at least that’s the way it appears. In short, it causes severe anemia. Illinois Extension’s Teresa Steckler, with funding from the Illinois Beef Association, has been pulling blood samples from herds in the area. She’s trying to determine if the strain of anaplasmosis is one called Mississippi that can be controlled by a vaccine, or if it is something else, “I’m just trying to see, with the movement of cattle throughout the United States, if we have a new strain? Is there a new agent transmitting the disease or is it just the tick that is causing the transmission? Is that linked to our deer population or some other population which the ticks may feast on and then move on to the cattle? It is related to the increase, and the guys are reporting to me, the big black horse flies”.
 
Cattleman, like Loy Hosselton in southern Illinois, don’t think there has been an increase in the tick population, but say the number of black horse flies has been on the upswing. Hosselton’s a vet and had ILLINOIS pull samples from his herd of about 50. He says herd-health is something that takes constant attention, even when the signs are there, “When they lose one head, they often times just throw that up to chance when it could be the sign of something more sinister”.
