Abstract
AbstractThe propagation of human respiratory syncytial virus (hRSV) was evaluated in thePteropus alectokidney (PaKi) cell line. At 20 hrs post-infection, immunoblotting of hRSV-infected PaKi cell lysates with anti-G, anti-N, anti-P and anti-M2-1 indicated expression of the respective virus proteins of the correct size. The hRSV-infected PaKi cell were also stained using anti-F, anti-G, anti-N, anti-P and anti-M2-1 and imaged using immunofluorescence microscopy, which confirmed high levels of virus infection, and the presence of numerous virus filaments and virus-induced inclusion bodies. PaKi cell monolayers also supported multiple cycle infection when hRSV was used to infect PaKi cells using a low multiplicity of infection. These data indicate that prior adaptation of hRSV was not required for its propagation in the PaKi cell line, and suggests that PaKi cell line is a suitable cell model system with which to examine virus-host interactions involving RSV infection in fruit bats.
