The Pathogenesis of Rabbit Red-Eye Disease

1 Rabbit Red-Eye Disease

I. The Pathogenesis of Rabbit Red-Eye Disease

As noted, pasteurella is the culprit, but not entirely—it normally lives in the upper respiratory mucosa and tonsils without causing disease. Only under stress (poor husbandry, dirty hutch, sudden weather, long transport) does resistance drop and the resident pasteurella multiply, causing endogenous infection and disease. It spreads via respiratory, skin, and mucosal routes; healthy rabbits catch it from sick rabbits or contaminated feed, water, supplies, or feces. Incidence is high year-round, all rabbits can be infected, weanlings most.

II. The Incubation Period of Red-Eye Disease

Incubation is 2–7 days. Early: the rabbit is reluctant or unable to open its eyes; conjunctiva, eyelids, and nictitating membrane swell, with constant tearing, pain, and white or gray corneal spots. As it worsens, the cornea thickens and ulcers, leaving scars and films. Usually no systemic signs, but when the eye suppurates, fever, poor appetite, and lethargy may appear, even blindness.

III. Effectively Stop Worsening and Treat Red-Eye Disease

At the above signs, treat promptly to control the condition. Use erythromycin or rifampicin (or chloramphenicol) eye drops; after about 3 days there’s good effect, but don’t slacken—keep medication until full recovery or it may relapse.

A reminder: rabbits get sick, especially common serious ones; learn both husbandry and disease defense, and vaccinate (e.g., pasteurella vaccine lowers infection risk). Above all, good husbandry matters—a good environment keeps rabbits healthy and reduces disease.
