New techniques for an old disease: Sarcoptic mange in the Iberian wolf

Evaluation of a Commercial ELISA for the Detection of Antibodies toSarcoptes scabieiin Wild Boar (Sus scrofa)

“…They were also lower than data obtained for pigs (sensitivity, 88.6%) with the same test (Lö wenstein et al 2004) and data obtained with the SARCOPTES-ELISA 2001 Dog applied on red fox sera (sensitivity, 98.2%; specificity, 91.9%; Nimmervoll et al 2013), but they were comparable to results obtained with an in-house ELISA applied on sera of free-ranging Iberian wolf (Canis lupus; sensitivity, 75%; specificity, 87.5%; Oleaga et al 2011).…”

Concomitance and interactions of pathogens in the Iberian wolf (Canis lupus)

“…was confirmed by mite isolation in 9 of the 12 animals that were submitted unfrozen(Oleaga et al 2011). Only in one case among all studied animals (in the wolf with the highest percentage of skin injured -90% -of those 9 with mange confirmed by Sarcoptes scabiei isolation) was it possible to confirm the presence of clinical CDV infection, revealed by histopathological examination of the skin where the Morbillivirus´presence was confirmed by immunohistochemistry.…”

“…Some diseases are thought to produce changes in population dynamics or temporal trends in wolves (Murray et al 1999), a species susceptible to a large spectrum of canine pathogens commonly found in domestic dogs (Canis familiaris), including Canine Parvovirus (CPV -Mech et al 1997), Canine Distemper virus (CDV -Müller et al 2011), the protozoan Leishmania infantum (Mohebali et al 2005) and the mite Sarcoptes scabiei (Todd et al 1981). Contact with these four agents has already been reported in Iberian wolf populations (Sobrino et al 2008 a-b; Oleaga et al 2011), but little is known regarding the temporal evolution of such contacts, the factors determining them and even the possible role that concomitance can play in the exposure or susceptibility to these pathogens. Both CDV and CPV can reduce wild canid populations recruitment by affecting young animals, while their long-term population effect seems to be moderate (Barker and Parrish 2001;Williams 2001;Almberg et al 2009).…”

“…Both CDV and CPV can reduce wild canid populations recruitment by affecting young animals, while their long-term population effect seems to be moderate (Barker and Parrish 2001;Williams 2001;Almberg et al 2009). The effect of sarcoptic mange on wolf population trends has been proposed to be limited in the study area during recent years (Oleaga et al 2011), while there is no data regarding Leishmania´s effect on wolf population dynamics.…”

“…This observation reveals the importance in wolf of early contacts with the parasite, and has been confirmed by authors in the study area by the detection during 2012 of a complete by 4 pups) severely affected by sarcoptic mange, with a much worse body condition -including caquexia, unpublished data-than that previously reported in adult wolves affected by this ectoparasite in Asturias. The marked increase in the number of animals with skin lesions during 2008 confirmed as mangy wolves at necropsy and detected at the same time in the field by camera trapping(Oleaga et al 2011) contrasts with the apparently stable behaviour of seroprevalence values for sarcoptic mange throughout time(Figure 1). ELISA seroprevalence did not differ between animals with and without mange lesions(Fisher test, p=0.495).…”
