Prevalence and Pathology of Sarcoptic Mange in Camels (Camelus dromedaries) in Semi-arid zone of Nigeria.
Abstract
The prevalence and pathology of sarcoptic mange among camels (Camelus dromedaries) in Maiduguri, Nigeria was investigated. A total of 264 camels slaughtered in Maiduguri abattoir were screened for mite infestation out of which 162 (61.3%) were found to be infected with Sarcoptes scabiei var cameli. The infection rate was higher (P<0.05) in females than males, the isolation rates in the sexes being 65.7% for females and 59.7% for males. A time series analysis showed that the infestation was highest in the rainy season (June-August) and lowest in the dry season (November-May). Grossly, the skins of affected camels were thickened, scaly and hairless (alopecic). Histopathological examination of such skin revealed subacute or chronic non-suppurative dermatitis with epidermal necrosis, hyperkeratosis, parakeratosis, acanthosis, marked fibroplasias and medical hypertrophy of blood vessels. These findings indicate that camel mange is a serious problem inNorthern Nigeria and needs further investigation.
