A new definitive host for Moniliformis cestodiformis (Acanthocephala: Moniliformidae): first report of a naturally infected European hedgehog (Erinaceus europaeus).

European hedgehogs, Erinaceus europaeus (Linnaeus, 1758), are small mammals found in western Europe and also in parts of northern Europe. They can be seen in rural, suburban and urban areas, but are usually found in grassland with edge habitats. These animals are omnivorous and serve as definitive or paratenic hosts for several parasites, including acanthocephalans (phylum Acanthocephala). During necropsy of a European hedgehog, a single adult parasite was collected from the intestinal lumen and preserved in 70% ethanol. After morphological evaluation of the specimen, it was identified as Moniliformis cestodiformis (von Linstow, 1904) (Acanthocephala: Moniliformidae). This is the first report of M. cestodiformis in a European hedgehog, as well as in Europe. More epidemiological studies need to be carried out to map the location and prevalence of this parasite in Portugal and the European continent.

Supplementary morphological data and molecular analyses of Eimeria labbeana (Labbé, 1896) Pinto, 1928 (Chromista: Miozoa: Eimeriidae) from columbiform birds in Portugal.

Columbiformes have a worldwide distribution, of which 166 species occur in Eurasia. They have been reported parasitized by coccidians recurrently in recent years; however, Eimeria labbeana (Labbé, 1896) Pinto, 1928, which is first Eimeria sp. from Columbiformes described in the late nineteenth century, is not taxonomically identified by its oocysts since the 1930s. In this context, the current study aimed to supplement the morphology of E. labbeana from Eurasian collared doves Streptopelia decaocto Frivaldszky, 1838 and from a common woodpigeon Columba palumbus Linnaeus, 1758 in Portugal, providing a preliminary genotypic characterization. Three of the four columbiforms were positive for oocysts identified as E. labbeana, which were morphologically revised as having micropyles, in addition to other minor adjustments. Oocysts from S. decaocto and C. palumbus were morphologically identical and equivalent in all morphometric aspects, besides having genotypic similarity of 99.5%. Phylogenetic analysis based on the mitochondrial cytochrome c oxidase subunit 1 gene resulted in a large clade with Eimeria spp. and Isospora spp. from different vertebrates and low similarity between Eimeria spp. from Columbiformes, whereas the phylogenetic analysis based on the small subunit ribosomal RNA gene resulted in well-supported monophyletic groups, including one with the coccidians of columbiform birds.
