Reservoir for Marburg in clay?
Proposal: the reservoir for the Marburg and Ebola Reston viruses might not be
in a living being but in a clay, shale or petrified wood deposit.
Reasoning:
1) A recent book on insect DNA preservation in amber mentions that very old
DNA has been discovered in some clays and shales in a preserved if not
totally intact state. This book, also, mentions the possibility of extracting
DNA from petrified wood.
2) Recent articles on possible origins of life have mentioned clay as an ideal
substitute for cell walls for early RNA and DNA.
3) Kitum cave contains a petrified rain forest with petrified bones of ancient
animals. I would assume that clay(s) would, also, be found.
4) As described in the "Hot Zone" elephants dig the rock (and clays) for
minerals and salts.
5) A search of the cave by a US-Kenya expedition turned up no reservoir animals.
6) As stated by Richard Preston in his book these viruses don't behave like
parasites rather they behave like hunters. He then wonders what life-form the
viral reservoir is. To me it seems quite likely that if they do the damage to
so many life forms that they seem to do then it would be in keeping with their
behavior if no life-form was the reservoir, rather a inorganic RNA "friendly"
reservoir.
7) Richard Preston when describing the macaque monkeys with the initial sickness
at Reston stated: "... In addition to vegetables and fruits, they eat insects,
grass, roots, and small pieces of clay..."
This isn't my area of expertise (computer scientist), but, I hope it stimulates
some useful thought in those whose area it is.
