The family Filoviridae comprises of one genus,
Filovirus, which contains two species, morphologically identical
but serologically distinct: Marburg virus and Ebola virus. There
are five Ebola subtypes BDBV, ZEBOV, REBOV, SEBOV and Taï
Forest ebolavirus (TAFV) which vary in pathogenicity, antigenicity
and genomic constitution[16]. BDBV, ZEBOV and SEBOV have
been accompanied with large EVD epidemic near the tropical rain
forests of Central and West African distant villages; among these
three ZEBOV are responsible for high mortality rates in humans.
REBOV and TAFV were not accustomed for illness or mortality in
human. The gene products of ebola and Marburg viruses exhibit a
noteworthy degree of similarity and in some areas extensive identity,
but are encoded in contradictory nucleotide sequences
