Ivermectin was used to treat ear mite infestation in 480 rabbits in 2 commercial rabbitries. Ivermectin (cattle formulation) injected sc at a dosage of 400 to 440 micrograms/kg of body weight repeated in 18 days appeared to be safe and effective in reducing the prevalence of ear mites in naturally infested rabbits. Psoroptes cuniculi (rabbit ear mite): This parasite causes otitis externa and rarely otitis media which can result in neurologic signs. Rabbits will present with head shaking, pruritus of ears and head and/or ear dropping (this may be the initial sign). Pinna and canals will be erythematous and will have a thick crust which is often red-brown in color. Other parts of the body may be affected. Do not attempt removal of crusts as this is quite painful! Use systemic anti-parasiticides.
Trixacarus caviae: T. caviae infestation should be considered as the first differential for any pruritic guinea pigConvulsions resembling seizures can be seen in infested guinea pigs due to the intense pruritus and debilitation experienced by some affected animals. Notoedres muris: Notoedric acariasis in hamsters affects mainly the ears, face, genitalia and tail. The diagnosis can be made by distribution and characterization of the clinical signs and by performing skin scrapings. Rats affected by notoedric acariasis resemble hamsters clinically, except that they sometimes present with nasal ‘horns.’ Frequently the mite can be visualized when performing a skin scrape of this nasal hyperkeratotic lesion.
Lice are usually seen in small numbers in rabbits and rodents. Large numbers may indicate an infestation with another skin parasite, or an underlying systemic disease (hypovitaminosis C in Guinea pigs, for example). Polyplax serrata (mice) and Polyplax spinulosa (rats) may serve as vectors for Mycoplasma (Haemobartonella) muris, Encephalitozoon cuniculi, and Eperythrozoon coccoides. Diagnoses of these parasitic disorders can be confirmed by finding the parasites on multiple skin scrapings. Medical grade spatulas are safe and easy-to-use instruments to perform the scrapings
In recent years, Ivermectin has fallen out of favor in rabbit medicine, replaced by another medication in the same family called Selamectin. Selamectin is sold over the counter under the brand name Revolution. Whereas Ivermectin is more effective when injected, Selamectin can be given topically with optimal results. Selamectin also treats a broader range of parasites than Ivermectin.
Features of Oral Ivermectin For Rabbits
Rabbits housed outdoors are prone to fleas, ticks and mites. Prevention and treatment of these detrimental pests is important to the health and well-being of your rabbits. Ivermectin is a medication that was popular in the 1980s for treatment and prevention of certain parasites, depending on the species and severity of the infestation. Consult a rabbit-savvy veterinarian as to the best medication and dosage for preventing and treating mites, worms and other parasites.
Ivermectin: 0.2 to 0.4 mg/kg q 2 weeks for 2 to 3 treatments PO or SQ. Ivermectin should not be administered orally to guinea pigs due to difficulties with GI absorption. For Notoedres muris in hamsters and rats: ivermectin 0.5 mg/kg administered q 1–2 weeks PO, SQ or in the form of a pour-on solution for at least 8 weeks is recommended. In rabbits, ivermectin has been used to treat Cheyletiella infestations in doses ranging from 0.2–2.1 mg/kg SQ q 11 days x 3 or 0.6–2.7 mg/kg PO q 10 days x 3.
