ABSTRACT
Objective
To report the diagnostic results, treatments, and outcomes in 13 dogs with suspected canine infectious respiratory disease complex (CIRDC)-associated pneumonia and Mycoplasma cynos–positive polymerase chain reaction (PCR).
Design
Retrospective and prospective case series.
Setting
Emergency and referral hospital.
Animals
Thirteen client-owned dogs with suspected CIRDC-associated pneumonia and a positive PCR.
Interventions
None.
Measurements and Main Results
All dogs with history, clinical signs, and radiographs consistent with CIRDC-associated pneumonia and a positive upper respiratory PCR that presented during a cluster from August 15, 2023, to September 9, 2023, were retrospectively and prospectively included in the series. Among the 13 dogs included, M. cynos was the sole pathogen detected in the airways of eight dogs, while M. cynos and Bordetella bronchiseptica were detected in five dogs. No viral etiologies were detected in this sample. Doxycycline, amoxicillin–clavulanic acid, and fluoroquinolones were frequently prescribed for ≥2 weeks. Follow-up was performed until 1 week after resolution of cough, evidence of radiographic resolution, or death of the dog. Twelve dogs survived, and one was euthanized.
Conclusions
Mycoplasma cynos was detected as the sole or co-occurring infection during this 3-week period, indicating it may be an important agent in some CIRDC clusters.
