    At Southern Methodist University campus about 6 miles south of Taos, New Mexico, we recovered tetrathyridia of Mesocestoides in five Peromyscus maniculatus in the summers of 2008 (3 of 129, 0.023%), 2009 (0 of 98, 0%), 2010 (1 of 112, 0.008%), 2011 (0 of 88, 0%), and 2012 (1 of 86, 0.011%). Tetrathyridia from the body cavity of one of the five infected mice were injected into the peritoneal cavity of laboratory white mice, Mus musculus. Our later examination of the laboratory mice revealed heavy infections of tetrathyridia continuing to reproduce asexually. Here we provide important new information on the prevalence of asexuality among tetrathyridia and underscore the need for further study of this variation among metacestodes of this cosmopolitan genus. Spanish abstract: En el campus de Southern Methodist University, aproximadamente seis millas al sur de Taos, Nuevo M茅xico, se colectaron tetrathyridia de Mesocestoides en cinco Peromyscus maniculatus durante los veranos de 2008 (3 de 129, 0.023%), 2009 (0 de 98, 0%), 2010 (1 de 112, 0.008%), 2011 (0 de 88, 0%) y 2012 (1 de 86, 0.011%). Tetrathyridia provenientes de la cavidad corporal de uno de los cinco P. maniculatus infectados fueron inyectadas dentro de la cavidad peritoneal de ratones Mus musculus del laboratorio. Posteriormente, nuestro estudio de los ratones del laboratorio revel贸 una fuerte infecci贸n de tetrathyridia, las cuales continuaban reproduci茅ndose asexualmente. Aqu铆 contribuimos informaci贸n nueva e importante sobre la prevalencia de la asexualidad entre tetrathyridia y senalamos la necesidad de m谩s estudios de esta variaci贸n entre metac茅stodos de este g茅nero cosmopolita
