Bats, emerging infectious diseases, and the rabies paradigm revisited
It is stated that:
“More recently, the asymptomatic excretion of RABV in the saliva of
experimentally infected vampire bats, which survived the challenge
during at least 2 years of observation, was documented again (18).”
But the cited research — despite what one might expect from the title
Salivary excretion of Rabies virus by healthy vampire bats
“Rabies virus was not detected in the saliva of any of the 11 animals
that succumbed (somewhat early) to rabies challenge, nor in the
control bats. In contrast, virus was detected early, and only once
(days 6, 6 and 21) in each of the three animals that survived rabies
challenge and remained healthy for at least 2 years after challenge.
At that time even vigorous dexamethasone and cyclosporine
administration failed to provoke further viral excretion.”
This seems to show that bats once recovered are no longer carriers and not that apparently healthy ones are.
