| mediterranean diplodus annularis (teleostei: sparidae) and its brain parasite: unforeseen outcome. | patterns of parasite load and aggregation of the bird trematode cardiocephaloides longicollis in its main intermediate host in the mediterranean, the annular sea bream, diplodus annularis, were studied in a large sample collected off valencia (spain) and are discussed within the context of the parasite induced host mortality hypothesis. the metacercariae were located within large composite cysts of host origin in the ventricles of the optic lobes of the cerebrum. a weak immunological response wa ... | 2005 | 15982922 |
| helminth fauna of the yellow-legged gull larus cachinnans in galicia, north-west spain. | thirty-six helminth species were found in 324 gulls examined during june 1994 to february 1996 from different localities of galicia: 25 trematodes (brachylaima sp., brachylecithum microtesticulatum, cardiocephaloides longicollis, cryptocotyle lingua, cryptocotyle concavum, diplostomum spathaceum, echinostephilla virgula, galactosomum phalacrocoracis, gigantobilharzia acotylea, gymnophallus deliciosus, gynaecotyla longiintestinata, himasthla elongata, himasthla quissetensis, knipowitschiatrema ni ... | 2005 | 16336721 |
| influence of host age and sex on the helminth fauna of the yellow-legged gull (larus michahellis) in galicia (northwestern spain). | we studied the influence of host age and sex on the helminth fauna of 324 larus michahellis captured in different locations in the region of galicia (northwestern spain). gulls were grouped into prefledglings, first-year immature birds, second- and third-year immature birds, and adults. second-year, third-year, and adult birds were grouped by sex. thirty-six helminth species were recorded. total species richness and mean infracommunity species richness were both significantly lower for pre-fledg ... | 2006 | 16883985 |
| helminth community structure of the mediterranean gull ( ichthyaetus melanocephalus ) in southern italy. | abstract the helminth community of the mediterranean gull ( ichthyaetus melanocephalus ) from the calabria region in southern italy was examined. ten species of helminths, including 2 cestodes ( alcataenia larina and tetrabothrius cylindraceus ), 4 digeneans ( aporchis massiliensis , brachylaima fuscatum , cardiocephaloides longicollis , and ornithobilharzia canaliculata ), and 4 nematodes ( eucoleus contortus , capillaria sp., cosmocephalus obvelatus , and paracuaria adunca ), were found. the m ... | 2011 | 21506790 |
| an optimised multi-host trematode life cycle: fishery discards enhance trophic parasite transmission to scavenging birds. | overlapping distributions of hosts and parasites are critical for successful completion of multi-host parasite life cycles and even small environmental changes can impact on the parasite's presence in a host or habitat. the generalist cardiocephaloides longicollis was used as a model for multi-host trematode life cycles in marine habitats. this parasite was studied to quantify parasite dispersion and transmission dynamics, effects of biological changes and anthropogenic impacts on life cycle com ... | 2016 | 27492874 |
| parasitic fauna of a yellow-legged gull colony in the island of escombreras (south-eastern mediterranean) in close proximity to a landfill site: potential effects on cohabiting species. | we identified the ectoparasites and helminth fauna of yellow-legged gulls (larus michahellis michahellis), breeding near to a solid waste landfill, and compared infection levels with those of other yellow-legged gull colonies. moreover, we analysed correlations between parasites and sex and body condition of yellow-legged gulls, co-infections and the helminth community structure in order to propose the role of this species as reservoir of certain parasites. we also discuss the potential transmis ... | 2015 | 26203998 |
| morphometric, molecular and ecological analyses of the parasites of the sharpsnout seabream diplodus puntazzo cetti (sparidae) from the spanish mediterranean: implications for aquaculture. | one of the fish species with the highest potential for aquaculture is the sharpsnout seabream, diplodus puntazzo cetti. among other aspects, the development of new fish cultures requires studies of potential pathogens that may compromise survival of the fish in captivity. moreover, both cultured and wild fish can act as sources or reservoirs of pathogens which may negatively affect other well-established cultures. we have studied the parasite fauna of the wild sharpsnout seabream, and monitored ... | 2015 | 24299967 |
