“…The higher prevalence of mites in sheep and goats with poor body condition than those with good body condition in our study supports earlier reports [ 8 , 18 ]. This finding most probably reflects the higher mite burden in animals with poor body condition that cause decline in live weight and overall productivity as has been argued before [ 5 ]. Poor body condition is usually associated with undernourishment which decline immunity increasing susceptibility to pathogens including ectoparasites [ 7 , 19 ].…”

“…Mange is a highly contagious, widespread condition that can be transmitted between animals by direct and indirect contact [ 4 ]. The economic impact of mites in infested animals comes from retarded growth, reduced daily weight gain, cost of treatments and labour, damage to the skin and hides and mortalities [ 5 ]. In addition, mites severely reduce the well-being of animals, reducing milk yield and hamper the milking process due to the restlessness of affected animals.…”

BackgroundMites are one of the most common and widely distributed ectoparasites of small ruminants in Ethiopia, contributing to major hindrances in livestock productivity in the country. Despite of this fact, specific study was not conducted on mites of small ruminants in Ethiopia. Therefore, the present study was performed from October 2009 to May 2010 to determine the prevalence and species composition of mites in three agroecological zones in north eastern Ethiopia. In addition, a questionnaire survey on mites was conducted to assess the control practices and awareness of farmers in the study areas.ResultsOut of a total of 1280 sheep and 1264 goats examined, 97(7.6 %) of sheep and 174(13.8 %) goats were infested with one or more species of mites. In goats an overall prevalence of 10.3 % Sarcoptes, 2.8 % Demodex and 0.6 % Psoroptes were recorded whereas in sheep an overall prevalence of 3.5 % Sarcoptes, 2.1 % Demodex and 1.6 % Psoroptes were observed. Sarcoptes (P = 0.03; OR = 2.1) and Demodex (OR = 3.25; p = 0.004) were significantly more common in young than in adult sheep. Demodectic mange was significantly higher in young (4.1 %) compared to adult (2.3 %) goats (OR = 2.2; P = 0.02). Significantly higher (P < 0.01) overall prevalence of sarcoptic and demodectic mites in both sheep and goats with poor than with good body condition was recorded. Results of the questionnaire survey supported results of our cross-sectional study.ConclusionsThis study demonstrates high prevalence of mange mites in sheep and goats of the study area. The study revealed that Sarcoptes is the predominant mite in both sheep and goats. Animal owners and veterinarians should consider mite control in small ruminants as part of the routine ectoparasite control in Ethiopia.

“…Among these, an infestation with Sarcoptes scabiei is one of the most frequent mite infestations worldwide [ 1 ]. S. scabiei is a burrowing mite, infesting not only dogs, but also cats [ 2 ], pigs [ 3 ], raccoon dogs [ 4 ], rabbits [ 5 ], sheep [ 6 ], and humans [ 7 ]. The mites preferentially inhabit less hairy regions of the host’s body, and the severity of clinical signs and mite infestation on skin surface areas may differ from one host species to another [ 8 ].…”

Efficacy of fluralaner administered either orally or topically for the treatment of naturally acquired Sarcoptes scabiei var. canis infestation in dogs

BackgroundThe efficacy of fluralaner, formulated as a chewable tablet (Bravecto™) or topical solution (Bravecto™ Spot-on Solution), was evaluated against naturally acquired Sarcoptes scabiei var. canis infestation in dogs.MethodsThe study was performed in privately-owned dogs naturally infested with S. scabiei var. canis. All dogs living in the same household as the infested dog were enrolled into one of 3 groups (2 fluralaner treated and 1 negative control). All dogs within one household were administered the same treatment, with one dog per household included in further observations and assessments. In total, 29 dogs confirmed positive for sarcoptic mange were included. On Day 0, all dogs in group 1 (n = 9) were treated once orally with fluralaner at a minimum dose of 25 mg/kg body weight; all dogs in group 2 (n = 11) were treated once topically with fluralaner at a dose of 25 mg/kg body weight; and dogs in group 3 (n = 9) were treated once topically with saline solution. Sarcoptes scabiei var. canis mites on each dog were counted before treatment and at 4 weeks after treatment in deep skin scrapings (~4 cm2) from 5 different body areas. Clinical signs of infestation (i.e. erythematous papules; casts, scales and crusts; body areas with hair loss) and pruritus were recorded at the same time points.ResultsSingle oral or topical treatment with fluralaner resulted in a 100 % reduction in mite counts post-treatment (group 1: P = 0.0009 and group 2: P = 0.0011). Resolution of clinical signs at four weeks post-treatment was variable, with improvement observed for erythematous papules, casts and crusts, and pruritus. All fluralaner treated dogs showed an improvement in overall hair re-growth compared with pre-treatment observations.ConclusionFluralaner administered either orally or topically to naturally infested dogs eliminates Sarcoptes scabiei var. canis mites and improves clinical signs over a 4-week observation period.

“…Scabies affects about 300 million people worldwide on an annual basis . There have been reports of Sarcoptes scabiei infesting diverse hosts including dogs, giraffes, pigs, raccoon dogs, rabbits, sheep and wolves, although the mites are largely host species‐specific in their natural ranges. Sarcoptic mange in dogs is often complicated by bacterial skin infections which contribute to the extent and diversity of skin lesions.…”
