Prevalence of Sarcoptes scabiei in domestic canines from Lomas de Sargentillo, Ecuador

Sarcoptic mange is a globally distributed ectoparasitosis that affects a wide range of mammalian hosts, including domestic and wild animals, as well as humans, and represents a relevant zoonosis. The objective of this study was to determine the prevalence of Sarcoptes scabiei in domestic canines under the care of an owner in Lomas de Sargentillo, Ecuador. A descriptive cross-sectional study was conducted during April and May of 2025, using a sample of 102 randomly selected canines. Deep skin scrapings were performed for microscopic diagnosis. The observed prevalence was 3.9 %. An association between sex and the presence of the mite was explored; however, no conclusive differences in infection risk were observed according to sex or age. These findings demonstrate the active circulation of Sarcoptes scabiei in the urban area of Lomas de Sargentillo, highlighting the importance of strengthening epidemiological surveillance, prevention and control measures, as well as health education strategies directed at dog owners, with relevant implications for public health and zoonotic control.
