All metacestodes were identified as cysticerci of Taenia omissa by morphological and molecular analyzes. Cytochrome c oxidase subunit 1 sequences from the new isolate T. omissa had more than 96.8% identity with other Peruvian isolates of the species previ ...

Abstract:
... Highly sensitive and accurate molecular diagnostic methods have not yet been employed for livestock trypanosomosis in the Brazilian Lower Amazon although the first reports of Trypanosoma vivax and Trypanosoma evansi in Brazil were in water buffalo (Bubalus bubalis) in this region. The present study assessed trypanosomosis in buffalo and cattle raised in communal and seasonally flooding pastures in ...

Abstract:
... We describe a case of microscopic liver lesion caused by larval cestode in a frugivorous bat (Molossus molossus) from the Western Brazilian Amazon. Histopathological analysis of liver indicated the occurrence of metacestode associated with multifocal histiocytic response and the phylogenetic analysis of Cox-I and 18S rDNA genes indicated that the parasite belonged to the family Paruterinidae. This ...
