EPIZOOTIOLOGICAL CHART OF AVIAN CHLAMYDIOSIS IN BOSNIA AND HERZEGOVINA

In the period from 2003 to 2008 we conducted a research on avian chlamydiosis in Bosnia and Herzegovina on a great number of domestic and wild birds from different localities. Diagnostic material from the wild birds was provided by the hunting societies during the hunting season while material from the domestic poultry was taken indiscriminately. Chicken samples are taken from the facilities for intensive production, namely parent flocks. Turkey samples are taken from the individual households keeping and breeding turkey on extensive basis (half – open type of breeding). Pigeon samples are provided from the central parts of Sarajevo where the pigeons live in a close contact with people. Also, pigeon samples are provided from around the town's bakery and a farm for intensive poultry breeding because the pigeons are considered a potential source of infection for other birds, primarily domestic ones, and also for the people. We also took samples of the breeding pheasants from a pheasant farm in Orasje, which is oriented toward breeding and releasing pheasants into their natural habitat, but also breeding for the needs of hunting industry. Samples from the wild/hunting birds (ducks and wild pheasants) were provided in the proximity of watercourses as their residence, and where the hunting is of a greater extent. To obtain valid diagnostic results we have used multiple diagnostic methods and tests: bacteriological examination to exclude cross reactions, IIF (indirect immunofluorescence) to confirm antibodies in the blood serum, ELISA (immunoesay) and EIA (quick immunoessay) to detect antigen, and conventional PCR and rRT – PCR to detect antigen as sensitive and sophisticated diagnostics methods.
