Abstract：
This study was conducted to evaluate the prevalence of otitis externa (OE) in cats using cytology, direct otoscopic examination, and parasitological examination through swabs and curettage, and to compare the accuracy between collection methods for parasitological examination. Direct otoscopic evaluation of the external auditory canal (right and left), swabs for cytological examination of the external auditory canal, and collection of cerumen for parasitological examination through swabs and curettage of 137 cats from a veterinary hospital care were conducted between March 2021 and March 2022. The influences of age, sex, habitat, street access, and the presence of fleas on OE were evaluated. Cytological evidence of OE was observed in 25.5 % of cats and was statistically associated with flea and mite parasitism. Otodectes cynotis was found in 13.9 % of the cats. Cocci and Bacilli were the secondary factors in 34.3 % and 22.9 % of cats with OE, respectively. The Malassezia genus was a secundary factor in 57.1 % of the cats with OE. The frequency of OE was high in cats receiving hospital care. O. cynotis was a frequent primary cause of OE in cats. The curette sampling method is a great option for diagnosing O. cynotis infestation due to its ease of use.
摘要：
这项研究是通过细胞学来评估猫的外耳炎（OE）的患病率，直接耳镜检查,通过拭子和刮宫进行寄生虫学检查，并比较寄生虫学检查收集方法之间的准确性。外耳道的直接耳镜评价（右和左），用于外耳道细胞学检查的拭子，在2021年3月至2022年3月之间，通过拭子和刮宫从一家兽医医院护理的137只猫收集了用于寄生虫学检查的耳垢。年龄的影响，性别,栖息地,街道通道,并评估了OE上跳蚤的存在。在25.5％的猫中观察到OE的细胞学证据，并在统计学上与跳蚤和螨寄生有关。在13.9％的猫中发现了耳形囊肿。球菌和芽孢杆菌是34.3%和22.9%OE猫的次要因素，分别。在57.1％的OE猫中，马拉色菌属是次要因素。在接受医院护理的猫中OE的频率很高。O.膀胱炎是猫OE的常见主要原因。刮匙取样方法是诊断O.膀胱炎感染的一个很好的选择，因为它易于使用。
