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.abstract 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 its-1 and its-2 regions of nuclear ribosomal dna. moreover, sequence analysis of the same genes was carried out on the morphospecies contracaecum chubutensis garbin et al. (2008) from phalacr ...201121506861
molecular identification and larval morphological description of contracaecum pelagicum (nematoda: anisakidae) from the anchovy engraulis anchoita (engraulidae) and fish-eating birds from the argentine north patagonian sea.anisakids use invertebrates as paratenic and/or intermediate hosts as a basic feature of larval transmission. the third-stage larva usually develops in invertebrates which are prey items of finfish paratenic hosts. contracaecum larvae molt twice inside the egg and hatch as free third-stage larvae ensheathed in the second-stage larval cuticle. copepods act as paratenic or obligatory hosts, usually ingesting these free l3 larvae, and fish act as intermediate/paratenic or metaparatenic hosts preyin ...201323500719
