MRLS Workshop Proceedings Available

The Kentucky Agricultural Experiment Station has published the scientific papers from the August 2002 workshop on mare reproductive loss syndrome (MRLS convened at the University of Kentucky's Gluck Equine Research Center. This information is available in book form or electronically at

The MRLS workshop proceedings is the definitive gathering of all types information regarding MRLS from researchers, practicing veterinarians, laboratories, and the industry. The workshop was sponsored by the Grayson-Jockey Club Research Foundation, Keeneland Association, The Gluck Center, and the UK College of Agriculture.

"We anticipate publication of the Proceedings will stimulate further activity to identify the cause of MRLS," said David Powell, BVSc, of the University of Kentucky Gluck Equine Research Center.

The topics are broken down into eight categories that each have summaries, plus a summary for the entire workshop. For example, Session 1 on Field and Clinical Observations on MRLS has five presentations and a summary. The presentations are: Clinical Observations Associated with Early Fetal Loss in MRLS during 2001 and 2002 Breeding Seasons; Field and clinical observations Related to Late Fetal Loss in Mares Affected with MRLS; Clinical Observations of MRLS in Critical Care Mares and Foals; Endophthalmitis: A Syndrome Associated with MRLS?; and Clinical Observations of the Pericarditis Syndrome. This collection of observations alone would make outstanding reading in order to help understand this syndrome.

The other categories are: Laboratory Correlates of MRLS; Epidemiological and Climatic Correlates of MRLS; Potential Candidates for the Eastern Tent Caterpillar MRLS-Inducing Agent; MRLS and Associated Syndromes: Toxicological hypotheses; Experimental Replication of MRLS; The Black Cherry Tree/Eastern Tent Caterpillar/Eastern Tent Caterpillar Frass System; and MRLS Monitoring Programs for 2002.

Also included in the publication are a list of abbreviations, bibliographies and suggested readings, and a list of participants of the workshop.

For all those touched by MRLS in 2001 and 2002, this publication from the workshop--and the individual articles it contains--are must reading to prepare for the future. More research is on-going on MRLS, and continued monitoring and experiments will hopefully reveal the causative factor(s) of this syndrome in order for horse owners to avoid these problems in the future.
