Plain-English summary
A study found that many dogs with coughing and sneezing were diagnosed with canine infectious respiratory disease complex (CIRDC), which is caused by various viruses and bacteria. The most common pathogens identified were canine parainfluenza virus (CPIV) and two types of bacteria called Mycoplasma canis and Mycoplasma cynos. Out of nearly 460 cases examined over five years, about 34% had viral infections and 58% had bacterial infections. This information can help veterinarians better understand and treat dogs showing respiratory symptoms.

Abstract
Canine infectious respiratory disease complex (CIRDC) is caused by different viruses and bacteria. Viruses associated with CIRDC include canine adenovirus type 2 (CAV-2), canine distemper virus (CDV), canine influenza virus (CIV), canine herpesvirus type 1 (CHV-1), canine respiratory coronavirus (CRCoV), and canine parainfluenza virus (CPIV). Bacteria associated with CIRDC include <i>Bordetella bronchiseptica</i>, <i>Streptococcus equi</i> subspecies <i>zooepidemicus</i> (<i>S. zooepidemicus</i>), and <i>Mycoplasma</i> spp. The present study examined the prevalence of CIRDC pathogens in specimens received by a Veterinary Diagnostic Laboratory in Georgia, USA., from 2018 to 2022. Out of 459 cases, viral agents were detected in 34% of cases and bacterial agents were detected in 58% of cases. A single pathogen was detected in 31% of cases, while two or more pathogens were identified in 24% of cases. The percentages of viral agents identified were CAV-2 (4%), CDV (3%), CPIV (16%), CRCoV (7%), and CIV (2%). The percentages of bacterial agents were <i>B. bronchiseptica</i> (10%), <i>Mycoplasma canis</i> (24%), <i>Mycoplasma cynos</i> (21%), and <i>S. zooepidemicus</i> (2%). Over the five-year period, the positive cases ranged from 2–4% for CAV-2, 1–7% for CDV, 1–4% for CHV-1, 9–22% for CPIV, 4–13% for CRCoV, and 1–4% for CIV. Overall, the most prevalent pathogens associated with CIRDC were CPIV, <i>M. canis</i>, and <i>M. cynos</i>.
