Trombiculosis is the infestation of a host by the larval form of mites belonging to the Trombiculidae family. Few data are available regarding this infestation in cats.
HYPOTHESIS/OBJECTIVES: The aim of this retrospective study was to report data, clinical signs, diagnostic and therapeutic features of feline trombiculosis.
Clinical records of cats presented for dermatological examination or annual vaccination in Italy, from 2002 to 2012, were retrospectively searched using the key words trombiculosis, cat and Neotrombicula.
Seventy-two indoor/outdoor domestic short-hair cats with infestation by Neotrombicula autumnalis were enrolled. Pruritus was reported by the owners in 43% of cases, while 57% of cats were asymptomatic. The most common clinical signs included sudden onset of pruritus and the appearance of orange-coloured granules on the skin. Mites were found incidentally in 12 cats. The larvae were localized in multiple sites in 68% of cases. The most frequently affected area was the ear (80.5% of cases). Mites were more often identified in autumn (41 cases). Eleven cats were diagnosed during winter, 13 in spring and seven in summer.
This retrospective study suggests that feline trombiculosis is probably underestimated as a cause of pruritus and dermatological lesions. Epidemiological data regarding this infestation in cats are still lacking, and it will be interesting to perform a multicentre study to increase knowledge of this disease.
恙螨病是由恙螨科螨类幼虫寄生于宿主体内引起的疾病。关于猫感染恙螨的资料较少。
假设/目的：本回顾性研究旨在报告猫恙螨病的数据、临床症状、诊断和治疗特征。
对2002年至2012年期间在意大利因皮肤病检查或年度疫苗接种就诊的猫的临床记录进行回顾性检索，检索关键词为恙螨病、猫和新恙螨属。
纳入72只室内/室外饲养的家猫，均感染秋新恙螨。43%的病例主人报告有瘙痒症状，57%的猫无症状。最常见的临床症状包括突然出现瘙痒和皮肤上出现橙色颗粒。12只猫是偶然发现有螨。68%的病例中，幼虫分布在多个部位。最常受影响的部位是耳朵（80.5%的病例）。螨在秋季检出的频率更高（41例）。11只猫在冬季被诊断出，13只在春季，7只在夏季。
这项回顾性研究表明，猫恙螨病作为瘙痒和皮肤病变的病因可能被低估。目前仍缺乏关于猫感染恙螨的流行病学数据，开展多中心研究以增加对该疾病的了解将很有意义。
