“…By contrast, lower percentages of mite‐positive sows were observed in the Weser‐Ems region, Germany (4% of 103; Busse & Aka, 1997), the Netherlands (4.5% of 200; Hollanders & Vercruysse, 1990) and Denmark (8% of 264; Hollanders et al ., 1992). The recorded percentage of fattening facilities that delivered mite‐positive pigs to slaughter was 77% in Germany (Hasslinger & Resch, 1992), 24% in the Netherlands (Hollanders & Vercruysse, 1990), 67% in Great Britain (McMullin et al ., 1992) and 78–87% in Spain (Gutiérrez et al ., 1996; Alonso de Vega et al ., 1998). The different prevalences in these study populations may reflect true measures or be skewed by bias, e.g.…”

A cross-sectional survey was performed in 110 randomly selected pig-breeding farms of southern Hesse, Germany to estimate the prevalence of ectoparasite infestations and to find possible risk factors. Ear scrapings of, if available, 10 sows per farm were examined for Sarcoptes scabiei var. suis (De Geer) (Acaridida: Sarcoptidae) by the potassium hydroxide digestion method, and a total of 2754 sows was inspected for skin lesions and infestations with Haematopinus suis (L.) (Anoplurida: Haematopinidae). Data on farm profiles and sows were collected by a questionnaire. In total, 19.1% and 2.5% of the sows were found to be infested with S. scabiei or H. suis, respectively. The percentage of mite or louse infestation was significantly higher in sows showing pruritus than in those without skin lesions. Both ectoparasite infestations were related neither to the age of sows nor their reproduction status, nor to the time interval to last ectoparasite treatment. Using farms as the unit of analysis, the estimated prevalence of mange mite and louse infestations was 45.4% and 14.5%, respectively. There was no significant association between the presence of S. scabiei and H. suis in the farms. Risk factors for S. scabiei infestation were mixed housing of dry and nursing sows in the same unit (vs. separate housing) and straw bedding (vs. strawless). For louse infestation, only mechanical cleaning of stable units (vs. additional use of disinfection methods) and pasturing of gilts and dry sows were identified as risk factors. The economic loss by S. scabiei infestation in the study population was assessed at euro 4200 per affected farm and year on average.

“…This study constitutes the first major report on occurrence of ectoparasites in free-range pigs in Kenya. The prevalence of S. scabiei mange pigs reported in our study was higher than that reported in other studies in Germany (19.1%) [5], Ghana (38.3%) [7], Botswana (40%) [6], and Tanzania (52%) [3] but was lower than that reported in breeding farms in Spain (92.8%) [14]. The cause of high prevalence of sarcoptic mange in pigs from the study area included free-range conditions and lack of ectoparasite control by majority of farmers.…”

“…The cause of high prevalence of sarcoptic mange in pigs from the study area included free-range conditions and lack of ectoparasite control by majority of farmers. The prevalence of mange was related to the age of pigs being highest in sows but lowest in piglets, and this has been previously reported in other countries such as Spain [14]. The higher prevalence of mange in sows could be related to the longer period the sows had been kept in the farm compared to other age groups of pigs.…”

A cross-sectional study was undertaken to determine the prevalence of ectoparasites and possible risk factors in free-range pigs from 135 farms of Busia District, Kenya. Three hundred and six pigs were examined for presence of external parasites using standard parasitological methods. Data on management practices including housing and history of acaricide spraying were also collected. The ectoparasites found in the pigs were Haematopinus suis (96.1%), Sarcoptes scabiei (63.7%), and ticks (29.7%). The tick species included Rhipicephalus appendiculatus (70%), Boophilus decoloratus (31%), and Amblyomma variegatum (12%). The occurrence of the infestations was associated with age, being highest in sows (S. scabiei) and finishers (ticks and H. suis). Male pigs had highest prevalences of H. suis and ticks, while female pigs had highest prevalence of S. scabiei. The prevalence of the parasitic infestations was significantly (P < 0.05) associated with their origin being either lower (H. suis and S. scabiei) or higher (ticks) in pigs originating from divisions with high rainfall. Housed pigs had significantly (P < 0.05) lower prevalence of H. suis and ticks than those from households without pig housing. It is concluded that the free-range pigs have high prevalence of ectoparasites, and effective control strategies focussing on improved animal husbandry and acaricide use should be implemented.

“…It is an important disease in cattle, pigs, sheep and goats worldwide, with many economical implications in prophylaxis and treatment (Alonso de Vega et al, 1998;Rehbein et al, 2003;Tarigan and Huntley, 2005;Menzano et al, 2007). Sarcoptic mange seems to show more dramatic effects in wildlife, severely affecting the population dynamics of different species (Mörner, 1992;Balestrieri et al, 2006).…”

Concern about emerging diseases has risen in recent years, and multihost situations have become increasingly relevant for wildlife management and conservation. We present data on Asturias, northern Spain, where 80 mangy red deer (Cervus elaphus) have been found since the beginning of the epizootic in chamois (Rupicapra pyrenaica parva) in 1993. We combine field and necropsy data with the results of a serosurvey using an in-house ELISA test to evaluate if deer mange due to Sarcoptes scabiei is an emerging disease in this area. The mean number of deer mange cases per year was 5, with a maximum of 16. No significant relationship was detected between monthly temperatures, rainfall or number of days with snow cover and the annual number of sarcoptic mange cases in red deer. Only 4 mangy red deer (5%) were detected outside the limits of scabietic chamois distribution during the same year, and all were less than 2500 m away from that limit. The longest distance reported between two consecutive mangy deer locations was 18 km. Mange cases were significantly more frequent in stags than in hinds and in adults than in juvenile deer. The time of the first mange detection in chamois in each sector, year with minimum number of chamois recorded, year with maximum chamois population decline rate and chamois density offered no significant correlation with red deer mange cases appearance moment and frequency. In the mange affected area, ELISA testing of 327 blood samples from hunter-harvested deer without obvious mange-compatible lesions revealed only 4 seropositive animals. All 83 sera from hunting preserves without clinical cases yielded negative ELISA results. According to these epidemiological data mange does not seem to threaten red deer populations in Asturias. However, continued monitoring of deer health and ELISA testing for sarcoptic mange is advisable. #
