Rabbit demodex

Systematic position: Demodex cuniculi belongs to the order Trombidiformes and the family Demodicidae. This microscopic mite is an obligate parasite that lives within the hair follicles and sebaceous glands of mammals, specifically favoring the rabbit host.

Host range: The primary host for this mite is the domestic rabbit (Oryctolagus cuniculus). In an agricultural context, it is considered a significant veterinary pest, as it directly impacts the welfare of livestock and the quality of pelt production in commercial rabbitries.

Biology and lifecycle: The lifecycle of Demodex cuniculi takes place entirely on the host and comprises four stages: egg, larva, nymph, and adult. The entire development cycle lasts approximately 18 to 24 days. These mites feed on sebum and epithelial cells, residing deep within the hair follicles, which makes them difficult to target.

Nature of damage and harm: Infestation leads to demodicosis, a skin condition characterized by localized or generalized alopecia, crusting, and papules. Severe cases cause intense irritation, inflammation of the dermis, and secondary bacterial infections, which compromise the overall health and growth performance of the affected animals.

Control measures: Managing Demodex cuniculi requires a comprehensive approach, including:

• Use of systemic or topical acaricides as prescribed by a veterinarian
• Strict sanitation protocols for cages and equipment
• Regular clinical examination of the rabbit herd
• Isolation of infected individuals to prevent transmission
