| Abstract | Antibodies toChlamydia sp., using CF test, were found in 435 of 912 (47.70%) pigeons examined from 1988 till 1993. The pigeons originated from two ecosystems, i. e feral pigeons from the city of Zagreb and calf feedlot. Of 834 feral pigeons, antibodies toChlamydia sp. were detected in 49.16% of birds. Feral pigeons were caught in various city areas, e.g., market-places, ZOO park and industry plants. The highest proportion of seropositive feral pigeons originated from the ZOO area (63.38%). Pathological and histhopathological examination revealed organ changes, e.g., spleen enlargement, liver degeneration, enteritis, opacified air sacs, and fibrinous pericarditis, indicative of chlamydiosis. Enlarged spleen was found in the pigeons with antibody titers of 1:32, 1:64 and 1:128. Fibrinous pericarditis was found on dissection in a pigeon with antibody titer of 1:128. Seasonal follow-up of antibody titer revealed that the proportion of seropositive birds is highest in spring (54.88%) and winter (53.51%), and lowest in summer. During spring and winter, elevated antibody titer was also recorded. In ringed pigeons, antibody titer was followed up on two or three occasions, showing titer changes to occur in 14 days at the earliest, and most commonly between day 35 and 92.In der Zeit von 1988 bis 1993 wurden 912 Tauben(Columba livia domestica) aus zwei verschiedenen ökologischen Gebieten gleichzeitig serologisch und pathologisch-anatomisch untersucht. 834 Tauben waren aus verschiedenen Zagreber Stadtteilen: Marktplätze, Tiergarten, Industriegebiet. 78 Tauben wurden an Farmen gefangen. Von ingesamt 912 mittels KBR-Verfahren untersuchten Tauben wurden Antikörper gegenChlamydia sp. in 47.7% in Serum nachgewiesen. In der Stadt Zagreb waren 49.16% serologisch positive Stadttauben und an den Farmen 32.05%. Der höchste Prozentanteil der serologisch positiven Zagreber Stadttauben wurde im Gebiet des Tiergartens (63.38%) nachgewiesen. Die pathologisch-anatomischen Befunde umfassen Enteritis, vergrößerte Milz, Leberdegeneration, getrübte Luftsäckchen und Perikarditis. Die vergrößerte Milz fand sich auch bei serologisch positiven Tauben mit Antikörpertiter von 1:32, 1:64 und 1:128. Bei der Taube mit dem Antikörpertiter 1:128 wurde noch eine fibrinöse Perikarditis festgestellt. Im Jahresverlauf wurden die höchsten Prozentanteile der serologisch positiven Tauben mit Antikörpertiter 1:32 und höher im Frühjahr, mit 54.88% und im Winter mit 53.51% nachgewiesen, die niedrigste im Sommer. Mit Ringen markierte Tauben zeigten Veränderungen der Antikörpertiter frühestens nach 14 Tagen, aber oft erst zwischen 35 und 92 Tagen.L'examen sérologique et pathologico-anatomique de 912 pigeons entre 1988 et 1993 a permis de déceler la présence des anticorps deChlamydia psittaci dans 437 sujets, soit 47.7% des sujets analysés. Ces pigeons étaient issues de deux milieux écologiques distincts, 834 provenaient de l'espace urbain de Zagreb (marché, parcs (jardin zoologique) et usines), 78 autres provenaient de fermes d'élevage de bovins. Les anticorps deC. psittaci ont été vérifiés dans 49.16% des pigeons urbains et dans 32.05% des pigeons provenant de régions d'élevage. Le plus haut pourcentage de cas séropositifs (63.38%) a été décelé dans la zone du jardin zoologique. Les changements pathologico-anatomiques enregistrés dans les organes sont les suivants: hypertrophie de la rate, dégénérescence du foie, entérite, péricardite fibrineuse, altération des sacs aériens. L'hypertrophie de la rate correspondait à un titre d'anticorps de 1:32, 1:64 et 1:128. Une péricardite fibrineuse a été constatée chez un pigeon titrant 1:128 d'anticorps. Le suivi dans le temps du titre d'anticorps montre que la majorité des pigeons séro-positifs a été relevée au printemps (54.48%) et en hiver (53.51%), la minorité au cours de l'été; au printemps et en hiver, les pigeons ont également révélé un titre d'anticorps supérieur. Le titre d'anticorps de pigeons voyageurs bagués a été suivi à deux ou trois reprises : les modifications ont été observées au plus tôt endéans les 14 jours mais le plus fréquemment entre 35 et 92 jours. |

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.
