Taliaferro and Sarles (1939) who studied the cellular reaction in the skin, lung and intestine of normal and immune rats after infection with N.muris, stated that “larvae were found penetrating the skin from a half hour through two hours after they had been placed on the skin. They seemed to penetrate directly…” Yokogawa (1922) observed that this parasite when placed on the skin of rats, penetrated into the tissues very quickly. He did not specify any time for their entrance.
