La derniere entite nosologique liee a cette espece, mise en evidence, est la borreliose de Lyme, dont la repartition est mal connue.

Il s’agit d’une espece exophile principalement sylvicole.Pour cartographier l’espece en France, nous avons elabore une methode reposant sur l’utilisation de l’indicateur vegetal. Les etapes de la methode (du zonage a l’echantillonnage de la tique) sont presentees : zonage phyto-ecologique du territoire fonde sur l’utilisation des cartes de vegetation a petite et moyenne echelles, choix des unites de vegetation – etages et series –, designation des sites de prospection, utilisation standardisee de la technique du drapeau.Quelques resultats sont analyses pour montrer l’interet et les limites de la methode. Ainsi, dans le quart sud-ouest de la France ou les series de vegetation sont bien individualisees, la frequence de l’acarien se revele tres variable d’une serie a l’autre. Dans ces conditions, la vegetation joue pleinement son role indicateur et les resultats obtenus refletent bien la variabilite ecologique manifestee par la vegetation. Par contre, dans le Massif Armoricain, la plus grande uniformite des conditions ecologiques se traduit par des series moins bien individualisees et par des populations de tiques distribuees plus uniformement.

Samplings were done weekly until there was no more faecal matter in the plots. Larval survival was determined using the Baermann migration technique, and we calculated the number of larvae per gram after the transformation of the weight of the faecal sample, in order to discard weight variations owing to climatic conditions. Over the whole period of this study, the percentages of larval survival in the faeces of the 12 deposits changed from the first week onwards. In those samples that were left in the pasture more than three weeks, survival was less than 50%. After the seventh week only very small numbers of active N. linearis larvae were obtained.

These fish act as definitive hosts in the biological cycle of these platyhelminths. Also H. gobii exists in G. niger, Z. ophiocephalus, S. cinereus and A. anguilla ; H. fasciata is found in G. niger ; and H. pulchella is only found in S. cinereus. In the case of the two gobies and the eel, these three congeneric digenes sometimes coexist in the same infracommunity. Spatio-temporal analysis of these different populations has enabled : 1) detection of seasonal variations in their structure, 2) identification of the relationships between the nature of their specificity and demographic strategy, and 3) the global absence of statistical dependence between the intensities of different species in the same infracommunity to be show. Implications arising from previous research concerning the demographic behaviour of these trematodes in their first intermediate host (mollusc compartment), were taken into account when interpreting structures observed in the definitive hosts. The problems of coexistence between these species, which are taxonomically very close in the same parasite community, and the under-lying speciation mechanisms are discussed in the light of population structuration.","PeriodicalId":72205,"journal":{"name":"Annales de parasitologie humaine et comparee","volume":"68 1","pages":"128-135"},"PeriodicalIF":0.0,"publicationDate":"1993-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1051/PARASITE/1993683128","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"57954651","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
