Johnson, L.R. and P.H. Kass, Effect of sample collection methodology on nasal culture results in cats. Journal of Feline Medicine & Surgery, 2009. 11(8): p. 645-649.
Feline chronic rhinosinusitis (CRS) is a common disease in cats with an unknown etiology. A number of studies have indicated that most cases of upper respiratory disease in the cat are complicated by secondary bacterial infections. Empiric antibiotic therapy is frequently employed to treat feline CRS. This study evaluated the effect of sampling method on culture results in 44 cats. The results indicated that aerobic and anaerobic cultures were positive significantly more often from nasal flush samples than from tissue biopsy samples. Culture results did not differ for Mycoplasma species between flush and biopsy samples though there was discordancy in 8 of 44 sample pairs for Mycoplasma species. This indicates that a failure to culture Mycoplasma species from a nasal flush might not be a true reflection of the absence of Mycoplasma species in the nasal cavity since a tissue sample may be required for isolation of the organism. Nasal flush is the preferred technique though for determining presence in feline nasal disease of potentially pathogenic bacterial organisms. [VT]
