A study to evaluate the primary causes associated with Pseudomonas otitis in 60 dogs

A study to evaluate the primary causes associated with Pseudomonas otitis in 60 dogs INTRODUCTIONThere are numerous studies that describe the investigation and therapy of Pseudomonas otitis (Wooley & Blue 1975, Foster & Deboer 1998, Martin Barrasa et al. 2000, Nuttall & Cole 2007, Wildermuth et al. 2007, Paterson 2012, Steen & Paterson 2012) but none that specifically consider the underlying primary causes or age of onset of cases of otitis with secondary Pseudomonas species infection. Common primary causes of otitis externa have been well‐described (Paterson 2002, Saridomichelakis et al. 2007, Zur et al. 2011), but there are sparse data on dogs diagnosed with otitis to describe the most common primary causes for Pseudomonas otitis. One study suggests that dogs with endocrine disease are more prone to infection with “rods” (Zur et al. 2011), but no other link is made between primary cause and type of secondary infection.

Abstract

INTRODUCTIONThere are numerous studies that describe the investigation and therapy of Pseudomonas otitis (Wooley & Blue 1975, Foster & Deboer 1998, Martin Barrasa et al. 2000, Nuttall & Cole 2007, Wildermuth et al. 2007, Paterson 2012, Steen & Paterson 2012) but none that specifically consider the underlying primary causes or age of onset of cases of otitis with secondary Pseudomonas species infection. Common primary causes of otitis externa have been well‐described (Paterson 2002, Saridomichelakis et al. 2007, Zur et al. 2011), but there are sparse data on dogs diagnosed with otitis to describe the most common primary causes for Pseudomonas otitis. One study suggests that dogs with endocrine disease are more prone to infection with “rods” (Zur et al. 2011), but no other link is made between primary cause and type of secondary infection. The bacterial flora of the normal canine ear is predominantly Gram‐positive cocci (Harvey et al. 2005). Acute cases of otitis externa are most commonly associated with Gram‐positive organisms such as Staphylococcus species (Grono & Frost 1969, Kowalski 1988). Chronic inflammatory change within the ear canal leads to increased numbers of Gram‐negative bacteria (Grono & Frost 1969, Sharma & Rhoades 1975), but there is no information
