Many people here are missing a very important point, the organisms being
discussed, Legionella sp., Vibrio sp., and E. coli, are gram negative
rods. Bacillus sp. and Clostridium sp. are gram positive rods. At this
time I am unaware of any human pathogenic gram negative rod that has the
ability to form a viable spore.
