Single B cells reveal the antibody responses of rhesus macaques immunized with an inactivated enterovirus D68 vaccine.

Arch Virol 2020 May 28. Epub 2020 May 28.

Institute of Medical Biology, Chinese Academy of Medical Sciences, Peking Union Medical College, Kunming, 650118, China.

Enterovirus D68 (EV-D68) infection may cause severe respiratory system manifestations in pediatric populations. Because of the lack of an effective preventive vaccine or specific therapeutic drug for this infection, the development of EV-D68-specific vaccines and antibodies has become increasingly important. In this study, we prepared an experimental EV-D68 vaccine inactivated by formaldehyde and found that the serum of rhesus macaques immunized with the inactivated EV-D68 vaccine exhibited potent neutralizing activity against EV-D68 virus in vitro.

Complete genome sequence of Tacaribe virus.

Arch Virol 2020 May 27. Epub 2020 May 27.

Junior Research Group Arenavirus Biology, Friedrich-Loeffler-Institut, Südufer 10, Greifswald, Insel Riems, Germany.

Tacaribe virus (TCRV) is the prototype of the New World arenaviruses (also known as TCRV serocomplex viruses). While TCRV is not itself a human pathogen, many closely related members of this group cause hemorrhagic fever, and thus TCRV has long served as an important BSL2 system for research into diverse areas of arenavirus biology. Due to its widespread use, a coding-complete sequence for both the S and L segments of the bipartite genome has been publically available for almost 30 years. Read More
