EBOLA is the name of deadliest virus (named after the Ebola River in Zaire) first emerged in Sudan and Zaire in 1976. Due to its highly pathogenic nature, scientific research conducted on Ebola ,conducted in a Biosafety Level 4 laboratory whereas for aids it was Biosafety level 2. Like all filoviruses, ebolavirus appear in the shape of a shepherd’s crook or in the shape of a “U” or a “6″, and they may be coiled, toroid, or branche.
“In general, ebolavirions are 80 nm in width, but vary somewhat in length. In general, the median particle length of ebolaviruses ranges from 974 to 1,086 nm , but particles as long as 14,000 nm have been detected in tissue culture. Ebola and Marburg are the only members of the filovirus family. Filoviruses (Ebola) are helical, non-segmented, negative, single-stranded RNA viruses, polymorphic, infectious and noninfectious, and have variable lengths.
