| Quail farming becoming more popular day by day in Bangladesh. Gastrointestinal nematodiasis is an important cause of loss of quail production. Our study report is an attempt to find out the prevalence of gastrointestinal nematodiasis in quail in Bangladesh. A total of 200 fecal samples were collected from quail farms from various regions of Bangladesh. The fecal samples analyzed by direct smear methods and nematodes identified by the presence of characteristic eggs in the feces. Five types of nematode eggs found on different farms. The overall prevalence of gastrointestinal nematodiasis were (17.5%), which could consider relatively higher. The highest rate of infection found for Heterakis gallinarum (7%) and the lowest rate of infection found for Trichuris spp. (1.5%). A significant difference in nematodiasis in different farms has not observed (p > 0.05). These findings help to undertake preventive measures for controlling gastrointestinal nematodiasis in quail farms in Bangladesh. Further studies should undertake for diagnosing other types of parasitic diseases in quails in Bangladesh.
