Trixacarus caviae infestation in two guinea pigs

Area of Science:

• Veterinary Dermatology
• Parasitology
• Rodent Medicine

Background:

• Sarcoptic mange is a common parasitic skin disease in various animal species.
• Guinea pigs can be susceptible to sarcoptic mange, presenting with significant dermatological signs.
• Accurate identification of the causative mite is crucial for effective treatment.

Observation:

• Two pet guinea pigs presented with generalized skin lesions.
• Clinical signs included intense pruritus (itching), widespread alopecia (hair loss), and hyperkeratosis (skin thickening).
• Skin scrapings confirmed the presence of Sarcoptid mites, identified as Trixacarus caviae.

Findings:

• Trixacarus caviae infestation was diagnosed in the affected guinea pigs.
• The mites were identified through microscopic examination of skin scrapings.
• Lime sulfur dip was administered as a treatment for the parasitic infestation.

Implications:

• This case highlights Trixacarus caviae as a cause of severe dermatological disease in pet guinea pigs.
• Successful treatment with lime sulfur suggests its efficacy in managing Trixacarus caviae infestations.
• Veterinarians should consider Trixacarus caviae in the differential diagnosis for guinea pigs presenting with pruritic, alopecic, and hyperkeratotic skin lesions.
