Plain-English summary
This study looked at cats with chronic rhinosinusitis (CRS), a condition that causes ongoing nasal and sinus issues, to see if certain germs were more common in them compared to healthy cats. Researchers collected samples from 10 cats with CRS and 7 healthy cats, checking for bacteria, fungi, and a virus called feline herpesvirus type 1 (FHV-1). They found that cats with CRS had more types of bacteria and Mycoplasma (a type of bacteria) in their nasal samples than the healthy cats, while no fungi were found in any of the cats. Although FHV-1 was not found in the nasal samples, its DNA was detected in some of the healthy and CRS-affected cats, suggesting it was present but not causing active infection. Overall, the study indicates that cats with CRS have more harmful germs in their noses compared to healthy cats.
Abstract
OBJECTIVE: To determine detection rates for feline herpesvirus type 1 (FHV-1), Mycoplasma spp, fungi, and bacteria in flush samples and biopsy specimens from the nasal cavities of cats with and without chronic rhinosinusitis (CRS). DESIGN: Prospective study. ANIMALS: 10 CRS-affected cats and 7 cats without signs of respiratory tract disease. PROCEDURES: Nasal flush samples and biopsy specimens were collected from all cats for bacterial (aerobic and anaerobic), fungal, and mycoplasmal cultures; additional biopsy specimens were collected for virus isolation and polymerase chain reaction (PCR) assay (to detect FHV-1 DNA). RESULTS: Aerobic bacteria were detected in flush samples from 5 of 7 control cats; culture of flush samples from CRS-affected cats yielded aerobic bacteria (9/10 cats), anaerobic bacteria (3/10), and Mycoplasma spp (2/10). No fungal organisms were isolated from any cat. Potential pathogens were isolated significantly more often from CRS-affected cats than from control cats. Bacterial culture of biopsy specimens yielded aerobic bacteria (2/7 control cats and 4/10 CRS-affected cats) and anaerobic bacteria (2/10 CRS-affected cats). Although FHV-1 was not detected in nasal biopsy specimens from control or CRS-affected cats, FHV-1 DNA was detected via PCR assay in specimens from 4 of 7 control cats and 3 of 10 CRS-affected cats. CONCLUSIONS AND CLINICAL RELEVANCE: Compared with findings in control cats, anaerobic bacteria, Mycoplasma spp, and a variety of potentially pathogenic organisms were detected more commonly in samples from cats with CRS. In both groups, FHV-1 was detected via PCR assay as a nonviable organism or in noncultivable amounts.
