First detection and molecular characterization of porcine epidemic diarrhea virus (PEDV) in India: evidence of a new variant in Karnataka.

ABSTRACT:

Background

Porcine epidemic diarrhea (PED) is a significant pig disease causing high mortality in suckling pigs and high morbidity across all age groups. It is highly prevalent in Southeast Asia, posing a threat of transboundary transmission to India. Although antibodies were detected as early as 2003 in Assam, there was no evidence of viral detection or molecular characterization until this study. This study reports the first clinical outbreak of PED in India, followed by the detection and genetic characterization of PED virus (PEDV) during 2022-23.

Methods

The outbreak was characterized, and fecal samples (n = 21) were collected from affected pigs. These samples were screened for PEDV using RT-PCR, targeting the N, S, and M genes. Serosurveillance was conducted in eight di
