The ribosomal protein S21 (bS21) gene has been detected in diverse viruses with a large range of genome sizes, yet its in situ expression and potential significance have not been investigated. Here, we report five closely related clades of bacteriophages
KZ52 is an antibody isolated from a human survivor of the 1995 outbreak in Kikwit that neutralises EBOV in vitro and recognises a conformational epitope at the base of the GP23,24,25. Human anti-EBOV GP mAb, KZ52 was unable to neutralise the EBOV GP pseudotyped HIV-1 (Fig. 2a) ...
