16S partial gene mitochondrial DNA and internal transcribed spacers ribosomal DNA as differential markers of Trichuris discolor populations.	Comparative morphological, biometrical and molecular studies of Trichuris discolor isolated from Bos taurus from Spain and Iran was carried out. Furthermore, Trichuris ovis isolated from B. taurus and Capra hircus from Spain has been, molecularly, analyzed. Morphological studies revealed clear differences between T. ovis and T. discolor isolated from B. taurus but differences were not observed between populations of T. discolor isolated from different geographical regions. Nevertheless, the mole ...	2011	22136768
Female-biased infection and transmission of the gastrointestinal nematode Trichuris arvicolae infecting the common vole, Microtus arvalis.	Previous studies addressing the importance of host gender in parasite transmission have shed light on males as the more important hosts, with the higher transmission potential of males being explained by the fact that they often harbour higher parasite loads than females. However, in some systems females are more heavily infected than males and may be responsible for driving infection under such circumstances. Using a wild population of common voles (Microtus arvalis), we showed that females wer ...	2011	22056297
characterization and pcr multiplexing of polymorphic microsatellite loci in the whipworm trichuris arvicolae, parasite of arvicoline rodents and their cross-species utilization in t. muris, parasite of murines.	trichuris arvicolae and t. muris are gastro-intestinal nematodes of respectively arvicoline and murine rodents. we aim to investigate the ecology of these trichuris species using population genetics. we sampled nematodes from rodents trapped in the east of france. after confirming the species identification of the nematodes using its1-5.8s-its2 ribosomal dna sequences, we isolated and characterized twelve dinucleotide microsatellite loci in t. arvicolae. a multiplex panel was developed. applicat ...	2009	19465060
multiple parasites mediate balancing selection at two mhc class ii genes in the fossorial water vole: insights from multivariate analyses and population genetics.	we investigated the factors mediating selection acting on two mhc class ii genes (dqa and drb) in water vole (arvicola scherman) natural populations in the french jura mountains. population genetics showed significant homogeneity in allelic frequencies at the dqa1 locus as opposed to neutral markers (nine microsatellites), indicating balancing selection acting on this gene. moreover, almost exhaustive screening for parasites, including gastrointestinal helminths, brain coccidia and antibodies ag ...	2008	18624885
molecular identification of trichuris vulpis and trichuris suis isolated from different hosts.	trichuris suis was isolated from the cecum of two different hosts (sus scrofa domestica -- swine and sus scrofa scrofa -- wild boar) and trichuris vulpis from dogs in sevilla, spain. genomic dna was isolated and internal transcribed spacers (its)1-5.8s-its2 segment from the ribosomal dna (rdna) was amplified and sequenced using polymerase chain reaction techniques. the sequence of t. suis from both hosts was 1,396 bp in length while that of t. vulpis was 1,044 bp. its1 of both populations isolat ...	2007	17004099
linking demography and host dispersal to trichuris arvicolae distribution in a cyclic vole species.	spatial structure in the distribution of pathogen infection can influence both epidemiology and host-parasite coevolutionary processes. it may result from the spatial heterogeneity of intrinsic and extrinsic factors, or from the local population dynamics of hosts and parasites. in this study, we investigated the effects of landscape, host dispersal and demography (population abundance and phase of the fluctuation) on the distribution of a gastro-intestinal nematode trichuris arvicolae in the fos ...	2007	17350018
the intestinal nematode trichuris arvicolae affects the fecundity of its host, the common vole microtus arvalis.	parasites have detrimental effects on host fitness. consequently, they play a major role for host population dynamics. in this study, we investigated experimentally the impact of the nematode trichuris arvicolae on the reproduction of its host, the common vole microtus arvalis. wild common voles were trapped in east of france and reared in standardized conditions before being experimentally infected. infection with trichuris arvicolae did not affect host consumption of food or water. parasitized ...	2007	17520287
a new whipworm from arvicolid rodents, trichuris arvicolae feliu et al., 2000, in the helminth fauna of poland.	during the parasitological examination of wild rodents from the vicinity of wrocław a single whipworm female was isolated from a field vole microtus agrestis. the nematode was determined as trichuris arvicolae. this is the first report of this parasite in poland.	2007	18441882
determination of trichuris muris from murid hosts and t. arvicolae (nematoda) from arvicolid rodents by amplification and sequentiation of the its1-5.8s-its2 segment of the ribosomal dna.	trichuris muris has been isolated from murid hosts ( apodemus sylvaticus and mus musculus) and trichuris arvicolae from arvicolid rodents in barcelona, spain. genomic dna was isolated and the its1-5.8s-its2 segment from the ribosomal dna (rdna) was amplified and sequenced using polymerase chain reaction techniques. the its2 of both populations isolated from apodemus and mus was 382 nucleotides in length and had a gc content of about 60.73%, while the its2 of t. arvicolae was 442 nucleotides in l ...	2002	12107482
genetic and morphological heterogeneity in small rodent whipworms in southwestern europe: characterization of trichuris muris and description of trichuris arvicolae n. sp. (nematoda: trichuridae).	genetic and morphological variability of whipworms trichuris roederer, 1761 (nematoda: trichuridae), parasites of small rodents in southwestern europe, was studied. isozyme patterns of natural populations of nematodes parasitizing rodent species of the muridae (apodemus sylvaticus, apodemus flavicollis, mus musculus) and arvicolidae (clethrionomys glareolus, microtus agrestis, microtus arvalis) were analyzed at 6 putative loci. two diagnostic loci were found in t. muris from muridae and from arv ...	2000	10864238
