Hydatigera taeniaeformis (Batsch)


Hydatigera taeniaeformis (Batsch)   ( Strobilocercus   )

(= Taenia taeniaeformis Batsch   ; = Taenia infantis Bacigalupo   )

Site of infection: Liver

Hosts: Mus musculus   , Rattus rattus   , and Sigmodon toltecus  

Localities: Xkalakdzonot and Paraíso

Prevalence and mean intensity (range): Mus musculus   1.4% (1/74) and 1 (1), R. rattus   28.8% (34/118) and 1.3 (1–4), S. toltecus   15.8% (3/19) and 19.7 (1–56) in Xkalakdzonot. Mus musculus   6.9% (11/159) and 1.2 (1–2) in Paraíso

Specimens deposited: MLP-He 7425, 7361, 7362 and CNHE 10701, 10702, 10707

Comments: Each cyst contained one metacestode, which measured from 4 mm to 140 mm prior fixation. The specimens collected in this study showed characteristics which agreed with descriptions given by Jones & Pybus (2001) and Fitte et al. (2017b), i.e. scolex with four suckers 692–877 in diameter and rostellum with double alternative crowns of 17–19 hooks each, longer hooks 377–410 in length and smaller hooks 221–253 in length.

In México, H. taeniaeformis   has been reported from M. musculus   in México City (García-Prieto et al. 2012), R. rattus   in Hidalgo (Pulido-Flores et al. 2005), R. norvegicus   in México City ( Caballero y Caballero 1939) and Michoacán (Hierro-Huerta 1992), and Sigmodon hispidus Say & Ord   in Nuevo León (Gutiérrez-González 1980).

In Yucatán, this cestode has been previously recorded from M. musculus   and R. rattus   in three localities in Mérida (116–124 km to Xkalakdzonot and 56–59 km to Paraíso) and in Opichén (30 km to Paraíso) (Rodríguez- Vivas et al. 2011; Panti-May et al. 2015, 2017). This is the first record of H. taeniaeformis   from S. toltecus   in México.
