Cheyenne, Wyo. – Preliminary tests indicate that 13 more
cattle in a western Wyoming herd may be infected with brucellosis.
That's in addition to the two cattle in which state authorities have positively confirmed brucellosis infections.
The herd belongs to a ranch near Daniel in Sublette County.
Assistant State Veterinarian Jim Logan says about 325 cattle from the herd have been subjected to preliminary blood tests and another 250 will be tested next week.
Plans are to test other nearby herds, but Logan isn't yet sure when those tests will be done.
The disease can cause pregnant cows to abort their young.
Wyoming is in danger of losing its brucellosis-free status if the disease is found in another herd or the Daniel rancher declines to slaughter his entire herd.
