Identification of wild rodents as intermediate hosts for Hydatigera taeniaeformis in Peru

Zusammenfassung: | Hydatigera taeniaeformis
is a cestode that uses felines and rodents as definitive and intermediate hosts, respectively. Its larval stage, or metacestode, infects a wide variety of rodent species and develops in the liver parenchyma into a cyst. The aim of this study was to evaluate the occurrence of
H. taeniaeformis
metacestode in various species of wild rodents from Peru. For this, the livers of 356 rodents were macroscopically examined for any parasitic form compatible with metacestodes. Metacestodes were identified by measuring characteristic morphological parameters, and the diagnosis was confirmed by molecular analysis of a fragment of the cytochrome
c
oxidase subunit 1 gene (
cox1
). Five rodents: two small-eared pygmy rice rats (
Oligoryzomys microtis
), two white-naped squirrels (
Simosciurus nebouxii
), and one pygmy rice rat (
Oligoryzomys
sp.) were infected with
H. taeniaeformis
metacestodes. The
cox1
sequences from our metacestodes showed up to 100% identity with previous
H. taeniaeformis
sequences from the GenBank. These results demonstrated the occurrence of
H. taeniaeformis
in new intermediate hosts, as well as the first molecular contribution for
H. taeniaeformis
from Peru. |
