The following plan represents the IACUC-endorsed steps that will be taken by the Office of Animal Resources when an excluded pathogen (viruses, bacteria, parasites) is detected in our animal colonies
-
Restrict room access to reduce risk of collateral transmission
- OAR will remove electronic access to the affected room doors as soon as the health reports indicate the detection of an excluded pathogen
-
Place quarantine signage and procure supplies
- OAR will label the doors to the affected rooms with signage detailing the agent detected and precautions to enter the room
- OAR will provide necessary supplies to manage the quarantine status
-
Communicate with affected labs on findings
- OAR will communicate with the affected investigators, key lab personnel and department DEOs for research staff affected by the pathogen detection
THE ABOVE ACTIONS (I-III) WILL OCCUR ON THE FIRST DAY THAT AN EXCLUDED PATHOGEN IS DETECTED
-
Animal room access restrictions
- OAR will permit access to the quarantine rooms for up to two lab staff members
- Lab staff assigned to the quarantine rooms will only have access to the quarantine rooms within OAR housing
- Lab staff designated to work in the quarantined rooms will be trained on proper quarantine procedures prior to being granted access to the affected rooms
- OAR will not assign affected investigators additional housing rooms within the vivarium
- OAR will permit access to the quarantine rooms for up to two lab staff members
-
Animal movement restrictions
- Animals will not be allowed to move outside of the quarantined room except under special circumstances as approved by an OAR veterinarian
Examples:
Approved terminal tissue collection
Euthanasia
- OAR will request that any animals from affected rooms that were in the labs or procedural spaces when the room was locked down are returned to the animal rooms immediately
- Lab staff can contact an OAR supervisor or veterinarian for assistance with this task
-
Bio-sampling of affected colonies and treatments
-
Parasites
- Affected sentinels and select colony cages will be sampled to confirm the presence of the excluded pathogen
- Fur mites - ectoparasites
- Fur samples or fur swabs will be collected from animals
- Pinworms - endoparasites
- Fecal samples will be collected
- Fur mites - ectoparasites
- All colony animals housed within the affected rooms will be treated after research notification and approval
- Affected sentinels and select colony cages will be sampled to confirm the presence of the excluded pathogen
-
Viruses/bacteria
- Affected sentinels and at least one animal per cage will be sampled to confirm the presence of an excluded viral agent
- Sampling could involve collecting a drop of blood and/or fecal sample
- Breeding moratorium will be enacted
- Cages that test positive for the excluded virus will be reported to the labs and the animals euthanized to reduce transmission risk
- Affected sentinels and at least one animal per cage will be sampled to confirm the presence of an excluded viral agent
-
-
Designation of procedural space for terminal tissue harvest
- OAR will consider the designation of a quarantine procedural space based on identified pathogen, investigator needs and space availability within the affected vivarium
- Designated quarantine lab staff will be trained on proper quarantine procedural space techniques prior to being granted access to the procedural space
- Tissues harvested must be fixed to prevent propagation of viable pathogens
-
OAR will retest for the presence of pathogens as appropriate to the agent, until clearance can be confirmed and quarantine restrictions lifted
-
Room decontamination
- Once the pathogen has been eliminated, OAR will remove and dispose of materials that cannot be decontaminated
- Animals will be placed in clean cages and moved to a sanitized room, where all lab staff will have unrestricted access to them
- Housing and procedure room(s) and equipment will be decontaminated by OAR prior to further animal use.
