Many species have tested positive for the Ebola virus, including orangutan, lowland gorillas, bats, etc. However no species seems to harbor it continuously, making primary prevention with public health initiatives less effective.
Since there are multiple and possibly unlimited vector species, the best preventative measure is to not interact with or eat wild animals at all.
Hmmmmm. Here are some thoughts. First of all, there is almost certainly no VECTOR involved. Vectors are transitory hosts that only communicate the virus between host and human and are usually arthropods... nothing of this sort has been suggested for filoviruses in a long time. OK, now on to the question of the reservoir...
If you make some assumptions about the sort of host-virus relationship is likely (e.g., a mammal, not a human commensal, etc.), you can get to a pretty narrow list. See the three papers from my research group that are attached. There are certainly others, but these should give you some idea.
Now, the interesting point is to compare Marburg virus and Ebola virus (the two are closely related genera within the family. Marburg is pretty clearly hosted by Rousettus aegyptiacus, with a possible secondary role of other bat species. And every Marburg occurrence for which information exists is tied to a cave or a mine. For Ebola, there is no cave-mine tie for any of the outbreaks, although there are detections of bits of Ebola genetic material in some bats. Clearly, regardless, the evidence for a bat tie for Ebola is much less clear than for Marburg, although it is pretty well assumed.
That is a nutshell description of where things stand ... hope this helps. ATP

I imagine that efforts to identify the reservoir of Ebola virus should be directed to fruit bats. There are strong evidences that outbreaks are related with fruit bat meat compsumption or close contact with those animals
most references suggested that the fruit bat is a primary reservoir for Ebola
