..sylvaticus. We propose the model A. sylvaticus/G. arfaai as a promising bioindication system to evaluate environmental lead exposure in terrestrial habitats, especially for non-urban areas...

..livia is proposed as another promising bioindicator system to evaluate environmental toxic element exposure, particularly Pb and Mn, in areas where pollution levels are still relatively low and where both common species are present...

..In addition, all available data on lead bioaccumulation by cestode parasites of terrestrial mammals are generally discussed...

..vison contributes to the maintenance of the life cycle of the pathogenic T. acutum and S. nasicola helminths, with possible implications for the conservation of the endangered European mink...

..Nevertheless, the culture of fresh faeces appears to be the best method to study infection of L. lutra by Strongyloides...

..We conclude that maintenance of the parasitic endemic status is probably due to the presence of animal carriers as well as to the physical features of some facilities where oocysts could remain viable and infectious...

..The helminth fauna of Spanish wolves is compared with that of other European wolf populations. Some epidemiological considerations of the helminth fauna of wolves in Spain and the health risk to humans are also discussed...

..This is the first study to report the infection of M. spretus and C. russula by C. parvum and the first finding of C. muris in M. spretus...

..ctenoides, a cestode that presents a relatively large body mass, were found to induce a reduction in rabbit condition...

..Furthermore, the large size of the cestodes used in the present study might also explain the relatively low element concentration values obtained...

..canadensis and L. rufus in America, and for L. lynx in Eurasia. The potential relationships between the parasitological data and some geographical, historical and dietary factors are discussed...

..The long-term character of this study was essential for obtaining these results and interpreting the complex relationships...

..schvalovoj from the oesophagus of L. lutra from Spain revealed new characters, above all in males, and allows for a better characterisation of this species. Since its original description E. schvalovoj has only been recorded in Spain...

..Helminthological differences between areas may result from the badger diet, abiotic factors and biocenosis present in each biogeographic area...

..The objective of this study was to analyze epidemiological and clinical characteristics of a measles outbreak in Catalonia, Spain, in 2006...

..The analysis of interspecific relationships between infracommunities shows that negative associations are more numerous than positive associations. The role of A. caninum in the community is compared with that of U. stenocephala...

..These ultrastructural characters are compared with other digenean species previously studied and the importance of different spermatological features is discussed...

..The ultrastructural characters of the mature spermatozoon of T. taeniaeformis are compared with those of other cestodes studied to date, with particular emphasis on other representatives of the family Taeniidae...

..subclavatus from those of other digeneans...

..It was again confirmed that the presence of granular material and the absence of both a periaxonemal sheath and intracytoplasmic walls are constant characters in the spermatozoa of all the Anoplocephalinae...

..Thus, we suggest that DGIs and male female DGIs are more widespread than previously thought, opening a new research avenue on apicomplexan transmission...
