Clinical and Laboratory Diagnosis of Mange Infestation among One-humped Camels (Camelus Dromedarius) at Tamboul Livestock Market, Sudan.

الملخص

This study was conducted from Tamboul livestock market, East of Gezira state
and about (150) km south of Khartoum. Three hundred suspected camels of different
ages, sex that came from different parts of Sudan to Tamboul livestock market were
studied in different seasons to determine the incidence rate of mange mite’s
infestation and predisposing factors association with mange in camels during period
from 2015 to 2016. The incidence of 24.7% mange mite’s infestation was recorded
during this study; visually the main characterization of lesion was loss of hair,
irritation, corrugation, crust conformation and skin thickening, Some cases infested
by sarcoptic mange revealed barrier with accumulation of white necrotic materials,
Lesions were noticed in all parts of the body and mostly in the head, neck, thorax and
gluteal region. Microscopically sarcoptic mange and psoroptic mange was detected;
also nymph, larvae and eggs were noticed. according to season the result was
revealed significant (p<0.05) higher incidence rate in winter (51.4%) followed by
autumn (24.3%) and summer (24.3%) respectively, while recorded no significant
variation in effect of mange on gender and age groups. also the mange infestation
registered significant increase of MCHC, hemoglobin and eosinophil. The study
concluded that the parasitological technique using 10% KOH is rapid, economic and
reliable technique to discover mange mite’s infestation among camel’s herds and
strategic application of anti-parasite drugs against mange disease during cold and
wet season was strongly recommended.
