Neural spread of herpes simplex virus to the eye of the mouse: microbiological aspects and effect on the blink reflex.

This paper reports the microbiological aspects of zosteriform spread of herpes simplex virus (HSV) to the eye in the NIH strain of inbred mouse. Microbiological data support the concept of true zosteriform spread of herpes simplex virus from the inoculation site on the snout to the trigeminal ganglion, and thence to the eye. Following zosteriform spread of HSV to the eye, there is a frequent bacterial superinfection and this is associated with a typical clinical picture. Treatment of the mice with intensive systemic and topical antibiotics is able to alter the frequency with which this type of keratitis is seen.
