Timed-exposure, dark-field photography was used to characterize the swimming behavior of Schistosoma mansoni miracidia in artificial pond water. Histograms and descriptive statistics were determined for helical swimming amplitude and wavelength, linear speed, turning frequency, and turning angle. Turning frequency could not be distinguished from a Poisson distribution so that turning appeared to occur randomly. Amplitude and wavelength showed no correlation. Faster miracidia exhibited less helical pattern while swimming. The effects of vertical movement of miracidia and of miracidial concentration were determined to be minimal.
采用定时曝光暗场摄影技术，在人工池塘水中对曼氏血吸虫毛蚴的游动行为进行表征。测定了螺旋游动幅度和波长、直线速度、转向频率和转向角度的直方图及描述性统计数据。转向频率无法与泊松分布区分开来，因此转向似乎是随机发生的。幅度和波长没有相关性。游动速度较快的毛蚴在游动时呈现出较少的螺旋模式。确定毛蚴垂直运动和毛蚴浓度的影响最小。
