BACKGROUND: Japanese encephalitis caused by Japanese encephalitis virus (JEV) is an endemic zoonotic disease of high public health importance in the Asian Pacific region. The aim of this study was to investigate the presence of JEV infection in commensal and field rodents in South China. MATERIALS AND METHODS: RNA copies of JEV were detected in brain samples of rodents using real-time RT-PCR. Detection of serum against JEV-reactive antibodies was performed using indirect enzyme-linked immunosorbent assay and microneutralization test. RESULTS: In total, 198 rodents were collected from Guangzhou City and Xiamen City between November 2013 and May 2014. JEV RNA was not detected in 188 brain samples. Forty-four in 96 serum samples (45.8%) were positive for JEV-reactive IgG antibodies. The prevalence of neutralizing antibodies to against JEV-reactive in these serum samples was 61.5% (24/39), with titers ranging from 1:10 to 1:56. CONCLUSION: Rodents are not known to play a role in transmission of JEV in Asia, nor is there an evidence to support a role for rodents in transmission of other related flaviviruses in China. However, in the current study, we detected evidence of JEV-reactive antibodies in large numbers of Rattus norvegicus and Rattus losea Swinhoe. Further studies of rodents as potential hosts of JEV or other related flaviviruses are warranted.
