Dear Colleagues,

The answers to these DEs are attached.

The Diagnostic Exercise #133 was contributed by Francisco A. Uzal, California Animal Health and Food Safety Laboratory System, San Bernardino Branch, University of California – Davis.

The Diagnostic Exercise #134 was contributed by Andrew Oates (Veterinary student, Pathology Club President, Class of 2020, UC Davis, Davis, CA) and Rebekah Keesler, DVM, Dipl ACVP (Formerly at CNPRC, UC Davis, Davis, CA; currently at Charles River Laboratories).

The Diagnostic Exercises are an initiative of the Latin Comparative Pathology Group (LCPG), the Latin American subdivision of The Davis-Thompson Foundation. These exercises are contributed by members and non-members from any country of residence. Please consider contributing a case to this initiative. It does not have to be something unusual and all sub-specialties of pathology are welcome! Previous cases are available online <https://nam11.safelinks.protection.outlook.com/?url=http%3A%2F%2Fwww.cldavis...> and in the members section of the AAVLD website <https://nam11.safelinks.protection.outlook.com/?url=https%3A%2F%2Faavld.memb...>. Contact me for further instructions on how to prepare and share your case.

Cheers, Vini
