Objectives The aim of this study was to compare the sensitivity of acetate tape impression with skin squeezing and superficial skin scraping methods for the diagnosis of burrowing mites ( Notoedres cati) in cats. Methods Samples were collected from 50 cats showing signs of notoedric mange. The most affected region was selected for sampling using acetate tape impression with skin squeezing, and superficial skin scraping. Results No significant difference was observed in the number of mites found by both methods, regardless of the stage of development of the mite. The tests showed a high correlation to the total number of mites (r = 0.928). However, in two animals it was possible to confirm the presence of N cati only by the acetate tape impression test. Conclusions and relevance We conclude that the acetate tape impression test is a good method for confirming the presence of N cati in cats. In our experience, this technique is as sensitive as superficial skin scraping, even in animals presenting with a low infestation. Moreover, the technique is less traumatic and allows the collection of clinical specimens in more sensitive locations, such as the eyelids, lips and paws.
目的 本研究旨在比较醋酸胶带压印法与皮肤挤压法及浅表皮肤刮擦法诊断猫疥螨（猫背肛螨）的敏感性。方法 从50只出现猫背肛螨病症状的猫身上采集样本。选择受影响最严重的区域，采用醋酸胶带压印法结合皮肤挤压法和浅表皮肤刮擦法进行采样。结果 无论螨的发育阶段如何，两种方法发现的螨数量均无显著差异。测试结果与螨的总数高度相关（r = 0.928）。然而，在两只动物中，仅通过醋酸胶带压印试验才得以确认猫背肛螨的存在。结论及意义 我们得出结论，醋酸胶带压印试验是确认猫背肛螨在猫体内存在的一种好方法。根据我们的经验，即使在感染程度较低的动物中，该技术与浅表皮肤刮擦法一样敏感。此外，该技术造成的创伤较小，能够在更敏感的部位（如眼睑、嘴唇和爪子）采集临床样本。
