Abstract：The aim of this study is to investigate the dynamic development and pathogenicity of the Metorchis orientalis in infected chicken. Metacercariae of the Metorchis orientalis in Pseudorasbora parva from epidemic area in Pucheng County, Fujian Province were isolated for quantitative infection of experimental chicken in different groups. These animals were then anatomized at different periods for collection rate of parasite and the identification of parasite development. Daily observation on clinical changes in experimental chicken was conducted, and the pathological changes in liver and gallbladder were also observed simultaneously by conventional paraffin section. The results showed that a rapid development of Metorchis orientalis in chicken, while the individual development was not simultaneous, and all parasites were not mature until 6th week p.i. The infected chicken grew slowly, in the situation of arrested development and high mortality. The longer for the infection time, the lower for the parasite recovery rate and severer the pathological changes in liver. It's suggested that Metorchis orientalis could develop rapidly in chicken in vivo and have high pathogenicity in the hosts.
