Genetic and morphological evidences for the existence of a new species of contracaecum (Nematoda: Anisakidae) parasite of phalacrocorax brasilianus (Gmelin) from Chile and its genetic relationships with congeners from fish-eating birds
Contracaecum australe n. sp. is described from the Neotropic cormorant Phalacrocorax brasilianus in Chile based on morphology and the sequence analyses of multiple loci, i.e., mitochondrial cytochrome oxidase 2, mtDNA cox-2, the small subunit of the mitochondrial ribosomal RNA gene, rrnS, and the IT...
