“…[12,16,17,21,22,25]. These differences in prevalence of B. ovis infestation of sheep might be due to dissimilarities in climatic conditions, animal husbandry and health care of sheep in the study areas [17].…”

“…Regardless of which, reports from different parts of country indicated that ectoparasitism of sheep is still alarming condition [4,7,12,16,17]. Additionally, to the best of our understanding, all the earlier reports on ked and lice of sheep in Ethiopia originated from studies of other ectoparasites, especially ticks and mites or based on examination of fresh sheep skins after slaughter.…”

“…This difference of small ruminant ectoparasite prevalence may be due to difference in agro ecology and diseases distribution. Furthermore the prevalence of ectoparasite was reported as 55.5% in sheep and 58% in goats and 50.5% in sheep and 56.4% in goats by Mulugeta et al [16] and Sertese and Wesen [17] in Tgray region and in different agro ecological zone of eastern Amhara respectively. From the above previous reports the prevalence of ectoparasite in goat was higher than in sheep but in this study the prevalence of ectoparasite in sheep was…”

A cross sectional study was carried out during the period between November, 2013 to April, 2014 to determine the prevalence of major skin disease and to identify the dominant risk factors for this disease in Gondar university veterinary clinic. A total of 1296 ruminants that came to the Clinic were involved in the study. Out of this 513(39.6%) cattle, 631(48.7%) sheep and 152(11.7%) goat was included. Skin scraping, morphological identification and clinical presentation were the methods employed for identification of mange mites and Dermatophilosis, gross ectoparasites and viral skin disease respectively. 468(36.1%) were infested with one or more skin diseases. The prevalence of skin diseases in cattle, sheep and goats were 142(27.68%), 268(42.47%) and 58(38.12%) respectively. The difference in the prevalence of skin diseases among the three host species was statistically significant (p<0.05). The major skin diseases identified on ruminants were tick 116(8.95%), mange 31(2.39%), lice 91(7.02%), sheep ked 72(5.56%), lumpy skin disease 29(2.24%), Dermatophilosis 9(0.69%), orf 45 (3.47%) and sheep and goat pox 77(5.94%).The prevalences of ectoparasites at genus level were tick (BoophilusHyalomma, Amblyommaand Rhipicephalus), mange mite (Demodex, Sarcoptesand Psoroptes) and Lice (Damalina and Linognathus). The difference in the prevalence of skin disease infestation between poor and good body condition was statistically significant in ruminants (P<0.001).The predilation site of skin disease were tick in hairless area, mange mite and lice in neck and head areas, Dermatophilosis on the back, orf in face region of, sheep ked in hairy parts of sheep, lumpy skin disease and sheep and goat pox in whole body parts of cattle and small ruminants. The study demonstrates that skin disease is among the most important health constraints of ruminants in and around Gondar town, hence requires immediate attention and control interventions.

“…Most ectoparasitic mites spend their entire lives in intimate contact with their host, so that transmission from host to host is primarily by physical contact. The generalized veterinary term for an infestation by mites in an animal is called acariasis and can result in severe dermatitis, known as mange or scabies, which may cause significant welfare problems, economic losses and outright deaths [8,9].…”

This study was conducted to determine parasiticidal efficacy of seven ethnomedicinal plants against Sarcoptes scabiei var. caprae of goats using in vivo and in vitro techniques. In vitro techniques for evaluation of efficacy of medicinal plants essential oils and fixed oils of seven medicinal plant extracts diluted at different concentrations (essential oils from 2.5% to 0.15625% and fixed oils from 160 mg/ml to 5 mg/ml) were added to petridishes containing adult stage of Sarcoptes scabiei var. caprae. After 3 h of contact, all concentrations of essential oil of Eucalyptus globulus and Cymbopogon citractus showed a good in vitro acaricidal efficacy as compared with the non-treated controls (p<0.05). However, Nicotiana tobacum fixed oil had significant (P<0.05) effect at a concentration of 160 mg/ml and 80 mg/ml. Pyrethrum cineraria folium fixed oil showed lower acaricidal efficacy (P<0.05) in all the concentrations of the extract as compared to the reference drugs. In vivo techniques undertaken for evaluation of efficacy essential oil of Eucalyptus globulus and Cymbopogon citractus at a concentration of 0.625% in 2% Tween 80 on two groups of (six animals each) Sarcoptes scabiei var. caprae infested goats were topically treated two times at 14 days interval and its compared with non-treated and treated (diazinone and ivermectin) controls of six goats in each group. The infected goats treated with the essential oils were cured completely. Statistically insignificant (p>0.05) difference was never observed in mite count, Mean Recovery Response (MRR) and degree of Skin Lesion Quality (SLQ) between goats treated with plant extracts and those treated with diazinone and ivermectin. Therefore, Eucalyptus globulus and Cymbopogon citractus extracts should be licensed for the treatment of Sarcoptes scabiei var. caprae.
