This report describes the parasitological and pathological information retrieved from the samples submitted to Regional Veterinary Laboratory, Bukit Tengah, Penang (MVKBT) followingan episode of histomoniasis in a small scale poultry farm. Liver and ceca from two dead turkey birds, water (n=5) and freshwater snails (Pomacea sp, n=7) were stored between 4°C to 10°C until analyzed. Soil samples (n=7) were preserved in 5% formalin and kept at room temperature prior to further testing. The soil samples were filtered through laboratory test sieves before the filtrates at each level were examined using direct microscopy. Portions of the liver were processed using routine paraffin technique for histopathological examination and found positive for Histomoniasis. Results from direct microscopy of the liver samples revealed Schistosoma mansoni ova, Sarcocystis sporocysts and Fasciola sp. Heterakis sp ova were detected from cecal content. Four out of seven soil samples were positive for Sarcocystis sporocysts, Coccidia oocyst, Strongyles ova and nematod larva. Water and freshwater snail samples were negative for cercaria of Schistosoma mansoni. This case was concluded as Histomoniasis, Sarcocystosis and helminthiasis with incidental finding of Schistosoma mansoni.
