The objective of the present work was to study microflora of the external auditory meatus in the patients presenting with bacterial otitis externa diffusa. The authors have analyzed the results of microbiological investigations involving 102 patients with this condition undergoing the treatment with 'Polidexa'. The characteristic of species composition of microflora associated with otitis externa diffusa is presented. The sensitivity of the most common pathogens responsible for the development of this pathology towards antibiotics contained in ear drops has been analysed. The advantages of the use Polidexa for the treatment of this acute ear disease are described.

Background: Canine aural cholesteatoma (more appropriately named tympanokeratoma) is an epidermoid cyst whose aetiopathogenesis remains poorly recognised in veterinary medicine. There are a few reports published, possibly because it may be underdiagnosed.
Objectives: To characterise the clinical aspects of dogs with tympanokeratoma, to describe the otoendoscopic, advanced imaging and histopathological findings of tympanokeratoma and to report the best approach to diagnose canine auricular tympanokeratoma in a retrospective study.

Canine otitis externa, characterized by the involvement of diverse bacterial species, notably Pseudomonas aeruginosa and Staphylococcus pseudintermedius, necessitates antibiotic administration as the primary therapeutic approach; however, prolonged treatment often precipitates antibiotic resistance. Therefore, the application of bacteriophages as antimicrobial agents has been of interest recently. However, phage therapy has limitations; its efficacy depends on the lytic capacity of the phage and the emergence of phage resistance, which can be overcome by using phage cocktails.

The external ear canal, characterized by species-specific structural and physiological differences, maintains a hostile environment that prevents microbial overgrowth and foreign body entry, supported by factors such as temperature, pH, humidity, and cerumen with antimicrobial properties. This review combines several studies on the healthy ear canal's structure and physiology with a critical approach to the potential existence of an ear microbiome. We use a comparative multi-species approach to explore how allergic conditions alter the ear canal microenvironment and cerumen in different mammalian species, promoting pathogen colonization.

Otitis externa is one of the most common diseases in otorhinolaryngological practice frequently requiring prescription of analgesic medications and antimicrobials. The total of 2714 patients were included in the retrospective study to evaluate bacterial etiology, effectiveness, and safety of topical empirical treatment of patients with diagnosed otitis externa during 2018-2023. The most common pathogens isolated were (38.

Bacterial skin infections, particularly pyoderma and otitis externa, are widespread in dogs, primarily caused by and species. This study evaluates the prevalence and types of bacterial pathogens in affected dogs in South Korea using a meta-analytical approach. Following the PRISMA guidelines, five electronic databases were searched for relevant studies published between 1990 and 2024.
