Feline otitis externa is a dermatological disorder with a multifactorial complex etiology.
This study aimed to investigate the prevalence of different etiological agents, particularly the parasitic and bacterial, responsible for the cases of feline otitis externa in Tripoli, Libya, and to assess the antimicrobial susceptibility of the bacterial isolates from those cases.
Cerumen and otic discharges of the suspected cats were collected for parasite detection and bacterial culture. Kirby-Bauer's disk diffusion method was used for antimicrobial susceptibility testing.
The results showed that otodectic mites and bacterial causes were equally the most prevalent in those cases, with a prevalence of 47.1% each. infestation was more frequently bilateral and severe. spp. were the most prevalent among bacterial causes (75%), followed by spp. (16.6%) and spp. (8.4%). Norfloxacin and gentamicin were the most effective antimicrobials against bacterial isolates, as they were effective against 83.3% and 70.8% of isolates, respectively.
infestation and staphylococcal infections constituted the most common etiology of feline otitis externa in Tripoli, Libya, and norfloxacin represented a cogent antibacterial for the treatment of otitis externa.
猫外耳炎是一种病因复杂的多因素皮肤病。
本研究旨在调查利比亚的黎波里猫外耳炎病例中不同病原体，尤其是寄生虫和细菌病原体的流行情况，并评估这些病例中分离出的细菌的抗菌药敏性。
收集疑似患猫的耳垢和耳分泌物进行寄生虫检测和细菌培养。采用 Kirby-Bauer 纸片扩散法进行抗菌药敏试验。
结果显示，耳痒螨和细菌病因在这些病例中同样最为常见，各占 47.1%。感染更常为双侧且严重。葡萄球菌属在细菌病因中最为常见（75%），其次是链球菌属（16.6%）和大肠杆菌属（8.4%）。诺氟沙星和庆大霉素是对分离出的细菌最有效的抗菌药物，它们分别对 83.3%和 70.8%的分离株有效。
耳痒螨感染和葡萄球菌感染是利比亚的黎波里猫外耳炎最常见的病因，诺氟沙星是治疗外耳炎的有效抗菌药物。
