Abstract

Classical swine fever (CSF) is a major constraint to pig production worldwide, and in many developing countries, the epidemiological status is unknown. Here, for the first time, molecular identification and characterization of CSFV isolates from two recent outbreaks in Nepal are presented. Analysis of full-length E2-encoding sequences revealed that these isolates belonged to CSFV subgenotype 2.2 and had highest genetic similarity to isolates from India. Hence, for CSFV, Nepal and India should be regarded as one epidemiological unit. Both Nepalese isolates exhibited significant sequence differences, excluding a direct epidemiological connection and suggesting that CSFV is endemic in that country.
