Subject: Animal #172541 Unfortunately, Animal ID#172541 presented with a grade 3 of 5 TB reaction at the 72 hour read. The animal was euthanized and tissues processed according to our algorithm for death in quarantine. No gross findings consistent with Tuberculosis were noted. No other abnormalities noted on gross necropsy. I have attached the necropsy report, and will share the histopathology once received back from the lab. Unfortunately this will delay the quarantine clear for this group as we are required by CDC regulation to have five negative TB tests from the date of the removal of this animal. The import will tentatively clear on 2/28/20 instead of 1/17/20. We request a credit for this animal.
