Aug 1, 2005 · Although many cases of acute infection respond to empirical topical treatment, dogs with chronic Pseudomonas otitis present an important challenge to clinicians. In these cases, successful outcomes depend on aggressive ear cleaning with …

Dogs presenting with Pseudomonas otitis externa may exhibit one or a combination of the following clinical signs: head shaking, aural pruritus, malodor from the ear, erythema, alopecia, signs of self trauma to the pinnae and pre-auricular region, shyness around the head, discharge from the ear canal, aural hematoma, and ulceration of the ...

Nov 10, 2023 · Pseudomonas ear infection is a specific and relatively common type of otitis in dogs. This condition is usually caused by a particular bacterium known as Pseudomonas aeruginosa, a type of opportunistic pathogen that is resistant to many antibiotics.

Dysbiosis often makes dogs more vulnerable to ear infections with Pseudomonas, particularly when accompanied by other factors, such as neglect. P. aeruginosa is not an obligate pathogen, and studies investigating the source of these infections often highlight environmental sources—particularly water [ 32 ], although nosocomial infections in ...

Nearly all ear infections involve commensal (e.g., staphylococci and Malassezia) or environmental (e.g., Pseudomonas) opportunists. The vast majority are secondary to pre-existing inflammation, foreign bodies, obstruction or other primary problems.

Determining the type of ear infection your dog has will help your veterinarian prescribe the right medications. ... This deep ear flush is an important treatment step for treating some types of ear infections, such as Pseudomonas, because the infection leads to a slimy layer of debris (biofilm) that blocks medications. Ear infections can spread ...

Pseudomonas is not usually isolated from normal dog’s ears; it can account for up to 35% of cases of otitis externa and or media (Cole and others 1998) and is challenging to manage. HISTORY & CLINICAL SIGNS Dogs often present with an acute onset painful ear with a large amount of purulent exudate, one or both ears can be affected.

Pseudomonas otitis can occur in cats and dogs of any age. Predisposing factors for Pseudomonas otitis are those that disrupt normal ear canal environment and allow bacterial invasion. All Pseudomonas otitis cases can benefit from thorough cleansing.

Pseudomonas aeruginosa is the most common 30 Gram-negative isolate in cases of canine otitis. This bacterium is a particular problem in cases 31 of otitis because the strains involved can be resistant to antibacterial drug treatment (Cole and 32 others 1998). Pseudomonas organisms have a complex array of virulence factors and resistance
