Otodectic and bacterial etiology of feline otitis externa in Tripoli, Libya.

Abstract

BACKGROUND: Feline otitis externa is a dermatological disorder with a multifactorial complex etiology. AIM: 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. METHODS: 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. RESULTS: 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 byspp. (16.6%) andspp. (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. CONCLUSION: 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.
