FIRST RECORD OF ADULT BRACHYLAIMA SP. (DIGENEA: BRACHYLAIMIDAE) RECOVERED FROM AN INDIGENOUS CHICKEN IN PENANG ISLAND, MALAYSIA
Most of the helminthic studies on chickens in Malaysia reported on the occurrence of nematodes and cestodes species, nonetheless a few species have also been reported from digeneans trematode. In this study, only one gravid adult digeneans from the family Brachylaimidae which were identified as Brachylaima sp. was found in one of the chickens examined from Penang Island, Malaysia. It was morphologically studied and was classified based on the external and internal morphology of the organs such as the position of genital pore, cirrus sac, reproductive organs (i.e ovary and testes), and the extension of the vitellarium as well as the shape of the eggs. This is the first report on the general morphological characteristics of a species of Brachylaima in Malaysia recovered from an indigenous chicken in Penang Island, the northern region of Malaysia. We want to increase the awareness of veterinarians, researchers as well as the farmers particularly on digeneans in indigenous chickens as they may serve as potential zoonotic reservoirs.
