Morphological and molecular data on helminths of Didelphis virginiana and Philander vossi (Mammalia: Didelphidae) from the Yucatán Peninsula, southeast Mexico.

In the present study, helminths from six Didelphis virginiana and one Philander vossi are reported using morphological techniques (clearing, staining, and scanning electron microscopy). Additionally, the 28S rRNA sequences of individuals from nine helminth taxa are provided. Phylogenetic analyses were performed with the new 28S rRNA sequences to confirm the identification and the genealogical relationships of the parasites.

Helminth fauna of the black goby L. (Gobiiformes: Gobiidae) from the Finnish Archipelago, Baltic Sea: Molecular and morphological data.

Black gobies () from the Finnish Archipelago, Baltic Sea, were screened for helminth infections in summer 2020. Helminths were identified morphologically and/or molecularly. Altogether 26 novel sequences were generated and analysed using maximum likelihood estimation.

Morphological and molecular characterization of Yamaguti, 1934 (Digenea: Hemiuridae) from the daggertooth pike conger (Forsskål).

Hemiurid digeneans conspecific with Yamaguti, 1934 (the type species of the genus Yamaguti, 1934) were collected from the stomach of the daggertooth pike conger (Forsskål) off the Persian Gulf of Iran. This study aimed to provide a detailed characterization of , including measurements, illustrations and scanning electron microscopy (s.e.

A new species of Notocotylus (Digenea: Notocotylidae) from the black-necked swan Cygnus melancorhyphus (Molina) of Argentina.

Notocotylus cygni n. sp. is described here, taken from the intestine of the black-necked swan Cygnus melancoryphus (Molina) of Patagonia, Argentina.

Diversity of myxozoans (Cnidaria) infecting Neotropical fishes in southern Mexico.

Myxozoans are a unique group of microscopic parasites that infect mainly fishes. These extremely reduced cnidarians are highly diverse and globally distributed in freshwater and marine habitats. Myxozoan diversity dimension is unknown in Mexico, a territory of an extraordinary biological diversity.
