Syphacia oryzomyos

Syphacia oryzomyos is a nematode that infects the marsh rice rat (Oryzomys palustris) in Florida. A similar species of Syphacia has been recorded from the rice rats Oligoryzomys fulvescens and Handleyomys melanotis in San Luis Potosí, but because only females were found, this worm could not be identified to species.
