Winter is at an end, Spring is here and with them some much needed snow and rain! In this issue, we highlight our Molecular Diagnostics Section and provide summaries of articles on Johne’s Disease and SIV.

Following 17 years of helping animal owners in Indiana and from around the country, and teaching Veterinary Pathology to aspiring students, Dr. Christine Holland retired at the end of December, 2012. Dr. Holland received her DVM degree and PhD in Veterinary Pathology from Purdue and began working at the ADDL and College of Veterinary Medicine in 1995. The ADDL has been fortunate to have many dedicated people at the lab over the years and we thank Dr. Holland for all of her help.
