Abstract:

This study aimed to find the cause of severe respiratory disease in fattened goat herds of many farms in Jiangsu province during 2013 to 2014. In this study, one caprine herpesvirus 1 named JSHA1405 was detected and isolated from nasal swab samples of goat herds with severe respiratory disease, and identified by transmission electron microscopy, PCR and virus pathogenicity test. MDBK cells infected with the third generation of JSHA1405 showed typical cytopathogenic effect (CPE). Under transmission electron microscopy detection, the enveloped virion could be observed with the diameter of 100 nm. Sequence analysis of gB gene indicated that JSHA1405 had some variation compared with E/CH strain, and the homology was 99.2%. Furthermore, the pathogenicity test indicated that JSHA1405 could induce high fever (peaked at 41.8℃) and lasted for about one week, other symptoms included depression, nasal discharge. Virus shedding could be detected from nasal and rectal swabs. Neutralizing antibodies appeared from the 7th day post infection (dpi) and peaked at 28th dpi. This is the first report about isolation, identification and pathogenicity study of CpHV-1 in China. The experiments demonstrated that the CpHV-1 strain JSHA1405 was pathogenic to goats. It provides foundation for further study of the viral etiology and the prevention and control of CpHV-1.
