The study was conducted on New Zealand white rabbits reared under intensive system of housing suffering from mange where Psorptes cuniculi was detected as the etiological agent. A single dose of Ivermectin was found to be highly effective and safe in treating the psoroptic mange in these rabbits.
In India mange infestation caused by Sarcoptes and Psoroptes species is a common disease of rabbits. The disease is more prevalent during stress. Low ambient temperature and high moisture during the winter months favour development of mange mites ( Blood et al, 2002).
Sporadic incidences and outbreaks of mange in rabbits have been reported from India and abroad (Ribbeck, 1976;).
MATERIALS & METHODS
The study was conducted on New Zealand
white rabbits reared under intensive system at Animal House, Institute
of Animal Health & Biological Products, Zakura. Animals of both sexes
aged between 6 months and 3 years revealed symptoms of acute dermatitis,
encrustation, loss of hair in face and head region. Skin scrapings were
collected and treated with 10% KOH solution. The scrapings were examined
for mites following the standard identification technique (Soulsby,
RESULTS AND DISCUSSION
The affected rabbits had developed bald
patches at the base of ear, face and the head with yellowish grey scab
in some cases provoking violent scratching. Scrapings from these lesions
showed presence of eggs, larvae and adult stages of Psoroptes
cuniculi mites. Following treatment with Ivermectin, a significant
and progressive decline in parasitic load was observed on 7th, 14th and
21st day and the lesions were found negative for mites and their
immature stages on 28th day post treatment.
