Duck farmers face significant economic losses due to infections caused by duck virus enteritis (DVE) virus and Pasteurella multocida (P. multocida), leading to high morbidity and mortality. These pathogens exhibit similar clinical manifestations. Thus, differentiating these infections based on clinical signs alone is highly challenging. The present study focuses on the detection of DVE coinfection among the pasteurellosis-suspected duck samples collected in Kerala during a 16 months study period. P. multocida was isolated from 19 samples in blood agar as mucoid, tiny dewdrop colonies. The isolates were further characterised by biochemical tests and confirmed by species-specific polymerase chain reaction (PCR). Among the 19 samples, 11 samples that were PCR positive for P. multocida (PM) revealed amplicons specific for DVE on PCR targeting UL2 gene of the DVE virus. The current study revealed the occurrence of concurrent infections of DVE and pasteurellosis in ducks that were immunised with the DVE vaccine. Despite vaccination against pasteurellosis in a few cases, the occurrence of P. multocida infection was observed in the study
