Rodent Quarantine

Two images of quarantine facilities

DVR maintains quarantine holding facilities for rodents coming into the NIH from un-approved vendors and foreign sources, such as Universities or oversea facilities.


DVR houses quarantined rodents in semi-rigid isolators. Most quarantine isolators can hold up to 10 cages, but DVR can accommodate larger shipments in a few larger isolators that hold up to 30 cages. Quarantine holding is charged per isolator day according to current rates (link to rates).

Animal from Non-Approved Sources – Rodents

Non-approved sources include universities, animal facilities outside of the NIH, overseas facilities, or production facilities that have not been approved by the NIH.

A Rodent Import Permit (NIH Form #2369-1) must be completed and approved by your IC rodent import officer (often the APD) and the Facility Veterinarian. A copy of the health surveillance report obtained within a calendar year must accompany the rodent import application. You IC rodent import officer or the Facility Veterinarian can assist in obtaining the necessary information.  

Once submitted to the DVR for review the DVR Rodent import Officer will determine the necessary isolation path. 

Isolation – Rodents

Depending on the health status of the sending facility, as determined by the Facility Veterinarian animals may need to be housed in isolation and undergo additional testing prior to housing in your animal room to protect the rest of your colony from adventitious infection. The Facility Veterinarian will discuss the length of isolation and the different testing options available on a case by case basis. Breeding animals during isolation will be approved by the Facility Veterinarian on a case by case basis and will depend on the space availability in the isolation room.
