Parálisis por garrapata - Overview

Definición:

Es la pérdida de la función muscular que resulta de una picadura de garrapata.

Causas, incidencia y factores de riesgo:

Se cree que las garrapatas hembra, tanto las de cuerpo suave como las de cuerpo duro, producen un tóxico que puede causar parálisis en los niños. Las garrapatas se adhieren a la piel para alimentarse de sangre y es durante este proceso de alimentación que la toxina penetra al torrente sanguíneo.

La parálisis resultante es ascendente, es decir, que comienza en la parte inferior del cuerpo y avanza hacia arriba. Es similar a la observada en el síndrome de Guillain-Barre y distinta a la observada en el botulismo y en la intoxicación paralítica por mariscos.
