| Abstract | Im Einzugsgebiet des Staatlichen Untersuchungsamts Mittelhessen wurden seit Januar 1993 bis August 1995 581 Füchse auf den Befall mitEchinococcus multilocularis untersucht. Die Befallsextensitäten der einzelnen Jahre schwanken zwischen 35,87% und 40,71%. Zwischen den Geschlechtern waren keine Häufigkeitsunterschiede nachzuweisen. Jüngere Tiere waren signifikant häufiger betroffen als ältere (α=<0,05). Zwischen einzelnen Regionen differierten die Anteile der Bandwurmträger zum Teil erheblich (33% bis 45%). Im Jahresverlauf nahm derEchinococcus multilocularis — befall vom 1. zum 4. Quartal hin ab.Der Vergleich mit Literaturdaten legt die Annahme nahe, daß auch im mittelhessischen Raum die Fuchsbandwurmpopulation dauerhaft zugenommen hat und nunmehr über den Werten liegt, die in klassisch enzootischen Gebieten Baden-Württembergs noch vor 10 Jahren gefunden wurden. Die Gefahr einer menschlichen Infektion dürfte somit auch für den untersuchten Raum steigen.Für die Hypothese eines erhöhten Fuchsbandwurmvorkommens durch hohe Fuchspopulationsdichten nach impfungsbedingter Tollwutfreiheit sprechen die zeitlichen Zusammenhänge.Im Vergleich der menschlichen Gesundheits- und Lebensgefährdung durch Tollwut oderEchinococcus multilocularis zeigt sich ein mindestens 10 × häufigeres Vorkommen tödlich verlaufender Fälle von Alveolarechinokokkose verglichen mit menschlichen Tollwuterkrankungen in Zeiten ihrer höchsten Inzidenz beim Fuchs. Die staatliche Tollwutbekämpfung durch die Fuchsimmunisierung könnte somit für die menschliche Gesundheit auch negative Effekte besitzen. Eine Erfassung menschlicherEchinococcus multilocularis — Infektionen durch die Einführung einer Meldepflicht wird für sinnvoll gehalten.In the environs of the State Investigation Bureau 581 foxes were examined for infection withEchinococcus multilocularis during the time period January, 1993 to August, 1995. The extent of infection in the individual years varies between 35.87% and 40.71%. No differences in infection prevalence were observed between the sexes. Younger animals showed a significantly higher rate of infection (α=<0.05). Among the individual regions investigated the proportion of tapeworm hosts differed in part considerably (33% to 45%). Over the course of the year the infection rate withEchinococcus multilocularis decreased from the first to the fourth quarter.A comparison with data from the literature shows that the prevalence of fox tapeworm has also permanently increased in Mid-Hessen, and that now the numbers exceed those of the classically enzootic regions of Baden-Württemberg of 10 years ago. The danger of human infection would thus increase for the areas investigated.The hypothesis that a greater occurrence of fox tapeworm is related to higher fox population densities due to the widespread vaccination against rabies is supported by the concurrence of these events.The comparison of the respective dangers to human health and life of rabies orEchinococcus multilocularis infection shows at least a 10 × higher occurrence of lethal cases of alveolar echinococcus infection as compared to human rabies infections when the incidence of this was most widespread among foxes. The statewide prevention of rabies through the immunization of foxes could thus produce negative effects for human health. The determination of humanEchinococcus multilocularis infections through official registration is to be considered.De janvier 1993 à août 1995, dans le bassin-versant ressortissant de l'Office de Recherches de Hesse moyenne, 581 renards ont été analysés quant à leur contamination parEchinococcus multilocularis. L'extension de l'Echinococcose au cours des différentes années variait entre 35,87 et 40,71 %. On n'observa pas de différences entre les sexes. Les sujets juvéniles étaient significativement plus atteints que les sujets adultes (α=<0,05). Entre les régions, la contamination variait fortement (33 à 45 %). Au cours de l'année, l'atteinte parEchinococcus multilocularis diminuait du premier au quatrième trimestre.La comparaison avec les données de la littérature permet de considérer que la population des cestodes du Renard en Hesse moyenne a constamment augmenté et se situe maintenant au-delà des valeurs qui prévalaient dans les enzooties du Baden-Wurttemberg voici 10 ans. Le danger d'une infection dans la population humaine pourrait ainsi également augmenter dans l'espace étudié. L'hypothèse selon laquelle une occurrence accrue de cestodes du Renard résulte de densités élevées de celui-ci, elles-mêmes provoquées par la récession de la Rage selvatique par vaccination, trouve dans les corrélations du moment un début de vérification.La comparaison des risques inhérents à la Rage selvatique et àEchinococcus multilocularis pour la santé voire la survie humaine permet de conclure que les cas mortels d'Echinococcose alvéolaire sont au moins 10 fois plus fréquents que les cas de Rage chez l'espèce humaine lors des périodes d'incidence la plus élevée chez le Renard. La lutte anti-rabique menée au niveau national par immunisation du Renard pourrait donc présenter des effets négatifs sur la santé humaine. Un suivi des infections humaines parEchinococcus multilocularis en instaurant une obligation de signalement est considéré comme opportun. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
