Taconic Biosciences Announces All US and EU Rat Colonies Free of Rat Polyomavirus 2

Hudson, NY, - December 14, 2016 - Taconic Biosciences, a leading provider of genetically engineered mouse models and associated services to researchers worldwide, today announced that all US and European commercial rat colonies are free of a newly discovered agent. IDEXX BioResearch announced it has identified rat polyomavirus 2, a novel virus, at the 2016 American Association for Laboratory Animal Science National Meeting in Charlotte, NC. According to IDEXX, rat polyomavirus 2 may be associated with morbidity and mortality in immunocompromised rats; however, no clinical illness has been reported in immunocompetent animals infected with the virus.

Utilizing a diagnostic assay developed by IDEXX, Taconic screened all commercial rat locations for the presence of this agent and is pleased to announce that all US and European commercial rat colonies are negative for rat polyomavirus 2. Taconic credits these results to a strong biosecurity program, which includes practices and procedures to prevent entry or spread of viral contaminants.

"We attribute these negative results for the novel rat polyomavirus to Taconic's strict bio-exclusion practices," said Dr. Jeffrey Lohmiller, DVM, MS, DACLAM, vice president of quality systems at Taconic Biosciences.

Taconic continually evaluates its health testing program and modifies the protocol based on current scientific literature and changing customer and/or research needs. As the biological impact of rat polyomavirus 2 is still being investigated, Taconic does not plan to add the virus to its routine health testing program. Taconic anticipates that strict bio-exclusion practices will continue to prevent entry of this agent.
