Comparison of acetate tape impression with squeezing versus skin scraping for the diagnosis of canine demodicosis

Abstract

This study compared the sensitivity of acetate tape impression and skin squeezing with that of deep skin scraping for the diagnosis of demodicosis in dogs. Demodex canis was detected in 100% of acetate tape impressions obtained after skin squeezing and in 90% of deep skin scrapings. There was a significant difference (P < 0.001) between the techniques in the total number of mites detected. Acetate tape impression with skin squeezing was found to be more sensitive than deep skin scraping and is an alternative diagnostic method for canine demodicosis.

Skin impression with acetate tape in Demodex canis and Scarcoptes scabiei var. vulpes diagnosis

“…Other affected breeds were the English bulldog, boxer, chow chow, great dane, miniature pinscher, border collie and beagle. These results are in accordance to previously reported information (Scott et al, 2001;Pereira et al, 2012), and confirm the hereditary compound in the susceptibility to develop demodicosis.…”

“…More recently, Pereira et al (2012) described the use of acetate tape impression method, reporting 100% efficacy against 90% of the deep skin scrapping in founding Demodex canis mites.…”

Clinical aspects of demodecosis in veterinary and human medicine

“…After performing a couple of prints, the tape is stuck to a microscopic slide, and the preparation is observed with 4 × and 10 × magnification. The results of comparative studies confirm a higher sensitivity of the adhesive tape test to scrapings in the diagnosis of canine demodicosis (41).…”
