Neurotoxins -
.
They
interfere
with
the
functioning
of
nervous
system,
usually
by
blocking
nerve
cell
transmission.
Neurotoxins,
even
those
produced
by
members
of
the
same
genus,
differ
markedly
in
their
mode
of
action.
Neurotoxins
responsible
for
botulism,
caused
by
Clostridium
botulinum,
bind
to
nerve
synapses,
blocking
the
release
of
acetycholine
from
nerve
cells
of
the
central
nervous
system
and
causing
the
loss
of
motor
function
.The
inability
to
transmit
impulses
through
motor
neurons
can
cause
respiratory
failure,
resulting
into
death.
