The University of Kentucky’s Livestock Disease Diagnostic Center (LDDC) has reported one confirmed case of mare reproductive loss syndrome (MRLS) this year. The case was from a farm in Boyle County that reported to have caterpillars at that time. Neil Williams, DVM, PhD, of the LDDC, said they recovered typical bacteria and the fetus had lesions consistent with MRLS.

Williams said late-term abortions and early fetal losses seen at the LDDC were typical for “normal” years in Central Kentucky, with very few early fetal losses.

Dana Zimmel, DVM, Dipl. ACVIM, ABVP, of the University of Florida’s College of Veterinary Medicine, said there had been no more reports of MRLS following the three confirmed by necropsies in Florida and the a couple of suspect cases.

Reports of a case in New Jersey cannot be confirmed due to closed offices caused by massive flooding in the area
