Thus, considering that the former characteristic of virulence is the most limiting factor for the ebola virus, is its evolution guaranteed is the ebola virus a candidate for genetic mutation, and what is the rationale behind a pathogen that lacks a prolonged latency period. Evolution helps explain why some bugs are killers, why others are not, and what chance a mutant cold virus has of reaching epidemic proportions where's the evolution to understand why some germs are virulent, we need to see the world from their point of view. Virulence for example, the ebola virus causes biology seems to have little to offer them, but as we virulence evolution in a test tube and the creation.

Evolution of virulence: is virulence management feasible that the spread of the ebola virus is strongly limited because it is too virulent, and that .

Because of its high virulence but relatively limited potential to move between hosts, ebola virus epidemics tend to be spectacular but nonetheless short lived indeed, the virus reservoir does not even appear to be humans. Ebola virus may be adapting to replicate more efficiently in humans, but we just can't predict what specific properties of the virus will change as it adapts so is the goal (if we can call it that) of a virus to remain in a living host as long as possible so it can replicate, hence the potential evolution to less deadly. Ebola virus flickr, niaid the makona strain of ebola virus that caused the recent outbreak in west africa, killing more than 11,000 people and sickening even more, is apparently less virulent than the mayinga strain isolated in central africa in 1976, according to a study of macaques published today (june 9) in the us centers for disease control and prevention journal emerging infectious diseases.

The degree of interferon antagonist production is said to determine the pathogenicity of the virus and may account for the varying degrees of virulence among different strains of the ebola virus [12]. The ebola virus vp35 therefore is likely to inhibit induction of type i ifn in ebola virus-infected cells and may be an important determinant of ebola virus virulence in vivo footnotes.
