Mycobacteriosis in the rabbit and rodent.

Spontaneous mycobacteriosis is rare in rabbits and rodents with the exception of the pygmy rabbit, and there are only a handful of reported cases involving other rodents. Mycobacterium avium complex was the most commonly identified organism in reports of spontaneous mycobacteriosis involving rabbits and rodents. The resistance of rabbits and rodents to mycobacterial disease has been useful in understanding the disease in humans and other animals.

Evaluation and refinement of euthanasia methods for Xenopus laevis.

The most common method of euthanasia for Xenopus species is by immersion in tricaine methane sulfonate solution (MS222). A wide range of doses of MS222 (0.5 to 5 g/L) have been recommended, but few reports describe dose-response testing, the time to loss of consciousness, or the reliability of euthanasia.

Tacrolimus ointment: a novel and effective topical treatment of localized atopic dermatitis in a rhesus macaque (Macaca mulatta).

An adult, male, rhesus macaque presented with pruritus and a focal, exudative, inflamed, erythematous skin lesion of approximately 2 cm in diameter on the ventral aspect of the mandible. The lesion resolved after 10 d of treatment with 1% chlorhexidine solution and triple-antibiotic ointment. However, the skin lesion subsequently recurred several times over a 2-mo period.
