Eastern Tent Caterpillars Cause Early Fetal Loss, Too

The case against Eastern tent caterpillars (ETC) causing mare reproductive loss syndrome (MRLS) is getting stronger, say researchers. Gavage (tubing into the stomach) of caterpillar larvae has been shown to cause late-term abortions that are characteristic of MRLS, which hit Kentucky and surrounding states in 2001 and 2002. Researchers in Lexington, Ky., recently determined that gavage of ETC can also cause early fetal loss (EFL), and that frass (excrement) doesn't cause EFL. The study was published in the Journal of the American Veterinary Medical Association.
