| present occurrence of anguillicola novaezelandiae (nematoda: dracunculoidea) in europe and its development in the intermediate host. | an examination of a sample of european eels, anguilla anguilla (l.), collected from lake bracciano near rome in 1993, the only known european locality with the occurrence of the introduced swimbladder nematode anguillicola novaezelandiae moravec et taraschewski, 1988, revealed for the first time the presence of two anguillicola species, a. novaezelandiae and a. crassus. in view of the investigations carried out by current authors in bracciano lake in the years 1982-1992, it is apparent that the ... | 1994 | 7883252 |
| the hsp70 response of anguillicola species to host-specific stressors. | the present study is based on infection experiments of two different swim bladder parasite species, anguillicola crassus kuwahara et al., 1974 and anguillicola novaezelandiae moravec and taraschewski, 1988, which were experimentally transferred to the two eel species anguilla anguilla linnaeus, 1758 and anguilla japonica temmink and schlegel, 1846, respectively. the host-parasite groups were selected due to their different grades of mutual adaptation. the main aim of this study was to analyze th ... | 2016 | 26920569 |
| size does matter-a closer look on anguillicola morphology. | the present study deals with morphological differences between two closely related parasitic nematode species (anguillicola crassus kuwahara et al., 1974 and anguillicola novaezelandiae moravec & taraschewski, 1988) in two different experimentally infected eel species (anguilla anguilla linnaeus, 1758 and anguilla japonica temminck & schlegel, 1847). furthermore, it considers the question whether size differences between those two species are ontogenetically determined or host species-dependent. ... | 2015 | 26096826 |
| effects of anguillicola novaezelandiae on the levels of cortisol and hsp70 in the european eel. | the nematodes anguillicola novaezelandiae and anguillicola crassus are both alien parasites of the european eel with severe adverse effects on their new host. both species differ in terms of their invasiveness and their severity of harmful effects on the european eel. the purpose of this study was to determine under laboratory conditions whether stages of a. novaezelandiae induce stress in european eels (anguilla anguilla) and if these levels differ from stress levels induced by a. crassus. we a ... | 2014 | 25096532 |
| comparison of infection success, development and swim bladder pathogenicity of two congeneric anguillicola species in experimentally infected anguilla anguilla and a. japonica. | two closely related parasites, anguillicola crassus and anguillicola novaezelandiae, originally parasitizing swim bladders of the japanese eel (anguilla japonica and the short-finned eel (anguilla australis), respectively, were used for analyzing the infection success of each parasite species on either long-known, recently acquired or new definitive host species and the associated effects on the eels' swim bladders. on that account, european eels (anguilla anguilla) and japanese eels were experi ... | 2014 | 25070578 |
| the phylogenetics of anguillicolidae (nematoda: anguillicoloidea), swimbladder parasites of eels. | anguillicolidae yamaguti, 1935 is a family of parasitic nematode infecting fresh-water eels of the genus anguilla, comprising five species in the genera anguillicola and anguillicoloides. anguillicoloides crassus is of particular importance, as it has recently spread from its endemic range in the eastern pacific to europe and north america, where it poses a significant threat to new, naïve hosts such as the economic important eel species anguilla anguilla and anguilla rostrata. the anguillicolid ... | 2012 | 22559142 |
| natural anguillicola novaezelandiae infection--is there seasonality in new zealand? | knowledge of natural anguillicola infections of short-finned eels (anguilla australis) in new zealand is very limited. so far, no study contains data on all life cycle stages of anguillicola novaezelandiae in naturally infected eels. in order to study the frequency of a. novaezelandiae in new zealand short-finned eels, we examined eels of the north and the south island for the presence of the swim bladder parasite. the results show that a. novaezelandiae is a common parasite of the short-finned ... | 2013 | 23388731 |
