viral fad

the salivary gland is target two
if rabies virus is to propagate
but first, to co-opt what its victims do
the CNS is where we cogitate
slow stages, up the axon to the brain
infection festers like a creeping tide
each neuron in the slow transmission chain
left DNA bread-crumbs before they died
whole neural pathways picked out in stark red
for those who read the antibody signs
as nerve-cells become crippled, if not dead
a mapping tool for brains, if not for minds
Louis Pasteur's vaccine's still pretty cool
but his pest's now nerve-mapper's trendy tool
