A total of 205 ducks, either sick or dead, brought for dead, brought for diagnosis to the Department of Pathology, BAU and to a private diagnostic center of Mymensingh town during the period from September, 2005 to June, 2006 was taken into consideration in this investigation. The number of ducks brought from different districts was 103, 72, 15, 09, 02, 03 and 01 from Mymensingh, Netrokona, Kishorgonj, Jamalpur, Sherpur, Sylhet and Tangail district, respectively. The flock size of the farms of Kalmakanda upazila of Netrokona district was observed closely. The diagnosis of different diseases or disease conditions was based on history, clinical signs and characteristic gross lesions at necropsy performed on the dead or sacrificed sick ducks. Tracheal fluke infection was observed in 30 (14.63%) cases out of 205. This infection was in 8 (3.90%) cases in pre-laying ducks and 22 (10.73%) in laying stage. Among the ducks at pre-laying stage, the proportional incidence rate of tracheal fluke infection was 9.41%, whereas, this rate was 18.33 in laying ducks.

Laboratories of the department of Pathology and department of Parasitology, BAU, Mymensingh, Kamlakanda and Barhatta upazillas of Netrokona district of Bangladesh
Pest Management
Pathology and parasitology of tracheal fluke of ducks will be studied.
Kamalkanda and Barhatta upazillas of Netrokona disgtrict are duck rearing areas, which are selected to conduct the study. Twenthy duck keepers will be selected from these two upazillas to record their problems and other information in duck rearing. side by side, to study the duck mortality pattern, the sick and dead ducks collected from the areas will be subjected to through necropsy to find out the causes of illness and to observe the presence of tracheal flukes if any. the fluke will be collected and preserved in 10% formalin.

Pathology and parasitology of tracheal fluke of ducks were studied. On the basis of morphology, the flukes were identified as Tracheophilus cymbius Kossak, 1911. The number of flukes present in the trachea varied from one to five. Free tracheal fluke were found but most of them were at the pharynx to obstruct the respiratory tract. Haemorrhages in the trachea were found in case of mixed infection. Histopathologic work is in progress.
