Release - Six EBOV genomes from Sierra Leone


We wish to share 6 EBOV Makona genomes obtained at the Virology Lab, National Institute for Infectious Diseases “L. Spallanzani”, Rome: Goderich1, Goderich2, Goderich3, Goderich4, INMI1 and INMI2. Viral RNA was extracted from plasma, and sequenced using Sanger technology. The sequences are available at:
We also computed a phylogenetic analysis, using MrBayes v3.2.5 (using GTR-GAMMA substitution model and 10million generations). We selected some previously published sequences, representative of all sub-lineages of Sierra Leone Clade 3 (SL3), as reported by Tong et al (Nature, 2015 Aug 26).
It is interesting to underline that Goderich1, Goderich3 and Goderich4 genomes belong to the so called “fishermen clade” ( ) or “Rosanda’s Ebola outbreak” ( ), and that this clade seems to form a new, different branch that start from 2.4 SL sub-lineage. Moreover, we identified 3 non-synonymous mutation that characterize this particular branch: one in NP (c1958t:P497S) and two in GP (a7267t:R410S and a7352g:K439E).
