中文摘要	The spatial distribution of the monogenean Dactylogyrus wunderi Bychowsky, 1931 on the gill filaments of the bream Abramis brama orientalis Berg (Leuciscinae) inhabiting the Irtysh River of Xinjiang, China was investigated from June to July 2012. D. wunderi was identified by sequencing a fragment of its ITS rDNA region. Sixty-five fish were examined, with 55% testing positive for monogenean infection. The prevalence of the parasite in the left and right gill arches was 46% and 48%, respectively. In fish with a large body length, the prevalence of the parasite and the infection intensity did not significantly differ between the right and left gill arches but both were slightly higher in the former. Among the three size groups of fish (small, medium and large) the prevalence and the intensity of infection were lowest in fish with small body lengths. The distribution of the monogenean population in the host gills showed an aggregate distribution, with little change in the degree of aggregation, suggesting that most hosts were either not or only slightly infected by D. wunderi and that the parasite infected only a few hosts. In addition, differences in D. wunderi infections between gill arches of A. brama orientalis were not significant (P > 0.05).
