Abstract - A retrospective study was conducted to investigate the occurrence of Schistosomus reflexus in calves from January 2012 to December 2016. Occurrence of Schistosomus reflexus in neonatal calves was studied in relation to breed, sex and seasons of calving. Clinical signs were angulation of limbs and no abdominal closure. Results showed 8.41% Schistosomus reflexus in surgically intervened cows. The percentage of indigenous calves affected with Schistosomus reflexus was as high as 42.86%, and in crossbred this was 57.14%. The percent of female calves born with Schistosomus reflexus was higher (60.0%) than the males (40.0%). Maximum occurrence (42.86%) of Schistosomus reflexus was recorded in the summer followed by rainy (37.14%) and winter seasons (20.0%). Among the studied areas, highest occurrence was recorded in Mymensingh Sadar (68.57%) followed by in Patuakhali Sadar (17.14%) and Bauphal (14.29%) upazilla of Patuakhali district. However, this study provides some basic information to veterinarians, researchers and farmers about the occurrence of Schistosomus reflexus in calves.
