Eastern Cottontail with Abscess and Suspected Tularemia

The combination of a wild lagomorph, a tarsal abscess, a pinnal lesion, and recent barehanded handling by a member of the public should raise concern for tularemia (Francisella tularensis), which is a recognized risk in rabbits and can be transmitted by direct contact, inoculation into skin breaks, aerosol, and arthropod bites. The pregnant rehabilitator should not be the primary handler; pregnancy is a relative contraindication to handling a suspect tularemia case because of the severity of typhoidal and pneumonic forms and because treatment options are constrained. The thumb abrasion is an inoculation site and should be washed with soap and water, covered, and the volunteer referred for medical evaluation with explicit mention of rabbit exposure. The animal should be placed in a single, escape-proof container with a lid, handled only with gloves and preferably a mask and eye protection, and kept away from the cats and dog, since cats are highly susceptible and can develop severe disease. The outdoor enclosure bank should not be used until the animal's status is resolved, because fomite and aerosol contamination of shared surfaces is possible. The health department and the supervising veterinarian should be contacted at the first opportunity.

Lancing and flushing a draining abscess is a surgical procedure and, in most jurisdictions, falls outside what a rehabilitator may do without veterinary direction and, depending on state law, without direct veterinary supervision. The plan should be rejected as written. Clinically, a walled-off abscess in a lagomorph is often a sign of underlying osteomyelitis or systemic infection, and simple drainage without addressing the deeper process risks recurrence and chronic pain. The animal also needs analgesia, which requires veterinary authorization. The correct path is to stabilize, provide warmth and a quiet enclosure, document the lesion with measurements and photographs, and arrange veterinary examination, including imaging if available, before any intervention. If the animal is a suspect tularemia case, the veterinarian should be informed before the appointment so that intake precautions can be arranged.

The decision should weigh four factors: whether the animal can be returned to function in the wild, whether it can be maintained without chronic pain, whether release is legal and biologically appropriate, and whether the rehabilitator has the resources to manage a prolonged course. Chronic osteomyelitis of the tarsus in a cottontail carries a poor prognosis for return to normal locomotion, and a rabbit that cannot run or dig is not a viable release candidate. Euthanasia is the defensible outcome and should be performed by or under the direction of a veterinarian. If the animal were instead a candidate for captive placement, the rehabilitator would need to confirm that state law permits placement of this species and that the receiving facility is licensed. Documentation should record the diagnostic results, the reasoning, and the final disposition.
