| Abstract | 107 Eier der Kanadagans aus Gelegen im Bereich des Naherholungsgebietes „Saaler Mühle“ in Nordrhein-Westfalen wurden morphometrisch, mikrobiologisch und serologisch untersucht. Untersucht wurde auf Erreger oder gegen diese gerichtete Antikörper von (i) Zoonosen (Salmonella sp.,Campylobacter sp.,Chlamydia sp.), (ii) die Erreger oder deren Antikörper von Tierseuchen (Virus der Newcastle Disease, Influenza A-Virus der Hämagglutinin (HA-)-Subtypen H5 und H7), (iii) Erreger oder deren Antikörper von bedeutenden Krankheiten des Wassergeflügels (Riemerella sp.,Pasteurella sp.,Escherichia coli, Schimmel- und Hefepilze, Paramyxovirus der Serotypen 4 und 6, Egg-Drop-Syndrome 1976, Entenpest-Herpesvirus).Aus Embryonen, Eihäuten und Dotter konnten kulturell keine Salmonellen isoliert werden. Mittels HELA-Zellkultur konnten keine Chlamydien nachgewiesen werden.Die Isolierung der Erreger von virusbedingten Tierseuchen (hier die Newcastle Disease und die klassische Geflügelpest) gelang nicht. Der Nachweis von Antikörpern gegen das Virus der Newcastle Disease gelang in Dotterproben von neun Eiern. Antikörper gegen das Influenza A-Virus des HA-Subtyps H5 wurden im Dotter aus einem Ei und Antikörper gegen das Influenza A-Virus des HA-Subtyps H7 wurden in zwei Eiern nachgewiesen.Der kulturelle Nachweis von Erregern bedeutender bakterieller Krankheiten des Wassergeflügels gelang hinsichtlichPasteurella sp. (ein Ei),Escherichia coli (ein Ei) undStaphylococcus sp. (23 Eier). Verschiedene Schimmelpilze wurden in sechs Eiern isoliert. Die Anzüchtung von Hefen gelang nicht. Aus einem Ei (Nr. 102) wurde ein Virus isoliert, das zur Gruppe der aviären Reoviren gehört. Antikörper gegen das Paramyxovirus des Serotyps 4 wurden nicht nachgewiesen. In vier Dotterproben befanden sich Antikörper gegen das Paramyxovirus des Serotyps 6. Antikörper gegen das Egg-Drop-Syndrom-1976-Virus befanden sich in 20 Dotterproben. Insgesamt 14 Dotterproben enthielten Antikörper gegen das Herpesvirus der Entenpest. Das Hepatitis-B-Virus der Gans konnte mittels PCR nicht nachgewiesen werden.Es konnten keine Erreger von Infektionskrankheiten nachgewiesen werden, die eine akute Gefährdung der Gesundheit von Menschen darstellen.Die nachgewiesenen Erreger/Antikörper von Geflügelseuchen und Krankheiten stellen eine potentielle Gefahr für das Hausgeflügel und für einige Arten frei lebender Wildvögel dar. Sorgfältige Beobachtungen der Kanadagans-Population und weitere Untersuchungen sind angezeigt.107 eggs of Canada geese from clutches within the environs of the recreational area of “Saaler Mühle” in North Rhine-Westphalia were morphometrically, microbiologically, and serologically analyzed. Investigations for the following pathogens or their antibodies were conducted: (i) zoonoses (Salmonella sp.,Campylobacter sp.,Chlamydia sp.) (ii) the antibodies to or the pathogens causing epidemics (virus of Newcastle Disease, Influenza A-Virus of haemagglutinin (HA-)- Subtypes H5 and H7); (iii) pathogens or their antibodies of primary diseases of waterfowl (Riemerella sp.,Pasteurella sp.,Escherichia coli, mold and yeast fungi, Paramyxovirus for the Serotypes 4 and 6, Egg-Drop Syndrome 1976, and duck plague herpes virus.Salmonella could not be culturally isolated from embryos, egg yolks, and egg membranes. Neither could Chlamydia be verified using HELA cell cultures.The isolation of pathogens for virally caused animal epidemics (Newcastle Disease and Fowl Pest was unsuccessful. A proof of the presence of antibodies to Newcastle Disease could only be shown in samples of egg yolks from 9 eggs. Antibodies to the Influenza A-Virus of the HA-Subtype H5 could only be determined in the yolk of one egg, and antibodies against the Influenza A-Virus HA -Subtype H7 could only be verified from 2 eggs.The cultural isolation of pathogens causing primary bacterial diseases of waterfowl could only be verified forPasteurella sp. (one egg),Escherichia coli (one egg), andStaphylococcus sp. (23 eggs).Various molds were isolated from 6 eggs. The cultural propagation of yeasts was unsuccessful.From one egg (Nr. 102) a virus belonging to the group of avian reoviruses was isolated. Antibodies against the Paramyxovirus Serotype 4 could not be detected. In 4 egg yolk samples antibodies against the Paramyxovirus Serotype 6 were found. Antibodies against the Egg-Drop Syndrome-1976 Virus were found in 20 egg yolk samples. A total of 14 yolk samples contained antibodies against the herpes virus of duck plague. The Hepatitis B virus of geese could not be determined with PCR.No pathogenic agents causing infectious diseases harmful to people were found.The demonstrated pathogens/antibodies of waterfowl epidemics and diseases present a potential danger for domestic poultry as well as for a few other species of wild birds. Careful observation of the Canada geese population and further investigations are necessary.107 oeufs d'oies du Canada provenant de couvées situées à proximité de l'espace récréatif de „Saaler Mühle“ en Rhénanie-Westphalie ont été examinés sur les plans morphométrique, microbiologique et sérologique. Ont été recherchés (i) les agents pathogènes ou leurs anticorps de zoonoses (Salmonella sp.,Campylobacter sp.,Clamydia sp.), (ii) les agents pathogènes ou leurs anticorps d'épizooties (virus de la maladie de Newcastle, A-virus de la grippe des sous-types H5 et H7 de l'Hémaglutinine (HA)), (iii) les agents pathogènes ou leurs anticorps de maladies significatives de la sauvagine (Riemerella sp.,Pasteurella sp.,Escherchia coli, moisissures et levures, Paramyxovirus des sérotypes 4 et 6, syndromes d'oviposition 1976, virus herpes de la peste des anatidés.A partir de cultures d'embryons, d'écaillés d'oeufs et de jaunes d'oeufs on ne put isoler des salmonelles. En faisant appel à des cultures HELA on ne put mettre en évidence aucune Chlamyde.L'isolement d'agents pathogènes d'épizooties virales (en l'occurrence la maladie de Newcastle et la peste aviaire classique) n'a pas abouti. La présence d'anticorps contre le virus de la maladie de Newcastle fut vérifiée dans des échantillons de jaunes de neuf oeufs. La présence d'anticorps contre le virus A de la grippe du sous-type de l'HA H5 a pu être vérifiée dans le jaune d'un seul oeuf et celle d'anticorps contre le virus de la grippe du sous-type de l'HA H7 a pu être vérifiée dans deux oeufs.La culture d'agents pathogènes de maladies bactériennes significatives de la sauvagine put être vérifiéeen ce qui concernePasteurella sp. (1 oeuf),Eescherichia coli (1 oeuf) etStaphylococcus sp. (23 oeufs).Différentes moisissures ont été isolées dans 6 oeufs. La culture de levures échoua.A partir d'un oeuf (Nℴ 102) un virus a été isolé relevant du groupe des réovires aviaires. L'existence d'anticorps du Paramyxovirus de sérotype 4 n'a pu être vérifiée. Dans 4 échantillons de jaunes d'oeufs se trouvaient des anticorps contre le paramyxovirus de sérotype 6. Des anticorps contre le virus du syndrome d'oviposition 1976 ont été retrouvés dans 20 échantillons de jaunes d'oeufs. Au total, 14 échantillons de jaunes d'oeufs contenaient des anticorps contre le virus de l'herpes de la peste des anatidés.On n'a pu détecter d'agents pathogènes de maladies infectieuses qui puissent constituer un danger majeur pour la santé humaine.Les agents pathogènes et leurs anticorps dont la présence a été avérée constituent un danger potentiel pour la volaille domestique de même que pour quelques espèces de l'avifaune sauvage. Des observations effectuées avec soin sur la population des oies du Canada de même que d'autres recherches sont renseignées. |

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.
