Trichuris sp.

Site of infection: Caecum

Host: Peromyscus yucatanicus

Locality: Paraíso

Prevalence and mean intensity (range): 20% (1/5) and 1 (1)

Specimens deposited: MLP-He 7429

Comments: The traits observed in the only non-gravid female collected in Yucatán belonged to Trichuris (Robles 2011) , i.e. anterior part of body being long, narrow, tapered and whip-like; posterior part of body being broad and handlelike with bacillary band located in anterior portion of body. Prominent vulva located just behind the junction of the esophagus and intestine. However, more material, particularly males, should be collected to identify this taxon at species level.

In México, six species of Trichuris have been reported (i.e. Trichuris citelli Chandler , Trichuris dipodomis Read , Trichuris elatoris Pfaffenberger & Best , Trichuris fossor Hall , T. muris , and T. silviae ) from several small rodents (Pulido-Flores et al. 2005; García-Prieto et al. 2012; Panti-May et al. 2015; Martínez-Salazar et al. 2016; Panti-May & Robles 2016). Unidentified species of Trichuris have been reported from small rodents such as H. pictus in Chiapas ( Caballero y Caballero 1958), Dipodomys spectabilis Merriam in Chihuahua (Rendón-Franco et al. 2014), and H. irroratus in Morelos (Ortíz 1999). This study reports for the first time a species of Trichuris from P. yucatanicus .
