Prevalence of Demodectic Mange in Canines of Kathmandu Valley having Skin Disorder and Its Associated Risk Factors

Abstract

Very little information is available regarding the demographics of the demodicosis in canines of Kathmandu valley and in Nepal as a whole. In this study, we determined the prevalence of the demodicosis and its associated risk factors from 110 canines of Kathmandu valley including both sheltered and free-roaming. The skin scrapping collected was dissolved in 10% KOH for the microscopic diagnosis of the mites. The overall prevalence of demodectic mange was found to be 29.1%. There was significant difference (p<0.05) between the prevalence rate among puppy (49.0%), adult (6.9%) and senior (33.33%). Whereas, there was no significant difference (p>0.05) between the prevalence rate among female (22.9%) and male (36.7%). Similarly, there was no significant difference (p>0.05) between the prevalence rate among short hair (40.7%), medium (25.67%) and long hair (28.5%). The association between the prevalence rate among good health status (10.7%) and poor health status (55.5%) is significant (p<0.05). Similarly, there was significant difference (p<0.05) between the prevalence rate among the free-roaming (48.9%) and the owned dogs (13.1%). At last, there was no significant association (p>0.05) between the prevalence rate among the pure breed (27.7%), cross (25.9%) and mongrel (37.5%). This study shows that demodectic mange is somewhat serious skin infection in canines of Kathmandu valley. The high significant association of age, health status and management with its prevalence suggests that the disease is more common in dogs which are left uncared and whose immune system is disturbed. Whereas, sex, breed and type of the hair of the dog did not have such significant relation with its prevalence. As demodicosis is a huge problem in street dogs, concerned organizations and authorities should develop proper planning for street dog management and their health care.

The prevalence and risk factors of canine demodicosis: A retrospective long-term study of 409 cases

“…The overall prevalence of demodicosis in the present study is comparable with the rates reported from Kathmandu Valley (Nepal) (29.1%) and Mexico (23%) (Rodriguez-Vivas et al, 2003;Shrestha et al, 2015). Male dogs were more frequently affected than females.…”

“…Demodicosis is often diagnosed in puppies and young dogs (Scott & Paradis, 1990;Shipstone, 2000;Shrestha et al, 2015). There are two types of demodicosis, including the localized (often found in puppies) and generalized forms.…”

Major Health Problems and Diseases of Street Dogs in Pokhara Valley, Nepal

“…Among 171 total rescued dogs, 69 (40.35%) were suspected for mange infestation. Bindari et al (2012) studied the prevalence of mange infestation in street dogs in Kathmandu Valley, Nepal. They took samples from 60 suspected positive street dogs and confirmed 67% positive.…”

“…Very few published data are available regarding the health problems of street dog in Nepal. Bindari et al (2012) studied the prevalence of mange in street dogs in Kathmandu, Nepal. They took samples from 60 positive suspected street dogs.…”

Canine generalized demodicosis (CGD) may be a severe and potentially life-threatening disease.…”
