The quantification of the different sizes and shapes of Fasciola hepatica and Fasciola gigantica from bovines has been achieved for the first time in natural allopatric populations. Linear measurements, areas and ratios of gravid adults and eggs of F. hepatica (from France and Spain) and F. gigantica (from Burkina Faso) were analysed using a computer image analysis system and an allometric model: (y2m - y2)/y2 = c(y1m - y1)/y1, where y1 = body area or body length, y2 = one of the measurements analysed, y1m, y2m = maximum values towards which y1 and y2, respectively, tend and c, b = constants. All the measurements overlap in the two fasciolids, apart from the distance between the ventral sucker and the posterior end of the body, body roundness and body length/body width ratio. The results obtained may be useful in Fasciola species identification in countries where both species coexist.
首次在自然异域种群中实现了对牛体内肝片吸虫和巨片吸虫不同大小和形状的量化。使用计算机图像分析系统和异速生长模型对来自法国和西班牙的肝片吸虫以及来自布基纳法索的巨片吸虫的妊娠成虫和虫卵的线性测量值、面积和比率进行了分析：(y2m - y2)/y2 = c(y1m - y1)/y1，其中y1 = 体面积或体长，y2 = 所分析的测量值之一，y1m、y2m分别是y1和y2趋向的最大值，c、b = 常数。除了腹吸盘与虫体后端之间的距离、虫体圆度和体长/体宽比外，两种片形吸虫的所有测量值都有重叠。在两种片形吸虫共存的国家，所获得的结果可能有助于片形吸虫物种的鉴定。
