Abstract：Through epidemiological investigation,clinical symptom observation,necropsy analysis,bacterial isolation and identification,and viral detection,this study examined multi-pathogen infections and drug susceptibility in reserve breeding pigeons from a large-scale pigeon farm in Guangdong under high-temperature and high-humidity conditions.The results revealed that the diseased pigeon flock was primarily infected with Newcastle disease virus(NDV),H9N2 subtype avian influenza virus,and pigeon circovirus(PiCV),accompanied by co-infections with Escherichia coli and Salmonella.Drug susceptibility testing showed that the pathogens were highly sensitive to gentamicin.The findings suggest that PiCV infection may enhance the susceptibility of pigeons to H9N2 avian influenza and play a critical role in mixed infections.This study provides clinical evidence for understanding the mechanisms of mixed infections in pigeons under immunosuppressive conditions and offers valuable insights for the comprehensive prevention and control of pigeon diseases.
