A total of 358 cattle was examined for schistosome infection in Zambian slaughterhouses. A total of 542 worms collected from 104 infected individuals was examined for glucose-6-phosphate dehydrogenase and phosphoglucomutase using isoelectric focusing. The overall prevalence of infection was 51%. Ninety three percent of the infected animals had less than 100 worm pairs in the mesenteric veins. Schistosoma mattheei was the predominant species (75%); S. leiperi (12%) and S. margrebowiei (2%) were also identified. The remaining 11% of the worms showed one of two distinct heterozygote patterns. Pattern A is identical to that of a laboratory-produced F1 S. mattheei x S. haematobium hybrid, but could also represent a S. mattheei x S. leiperi hybrid. Further studies are required to elucidate the origins of pattern B.
在赞比亚的屠宰场对358头牛进行了血吸虫感染检查。从104头受感染的牛身上收集了总共542条蠕虫，使用等电聚焦法对其葡萄糖-6-磷酸脱氢酶和磷酸葡萄糖变位酶进行了检测。总体感染率为51%。93%受感染的动物在肠系膜静脉中的蠕虫对少于100对。马修血吸虫是主要种类（75%）；也鉴定出了莱氏血吸虫（12%）和马格雷博维血吸虫（2%）。其余11%的蠕虫呈现出两种不同的杂合子模式之一。模式A与实验室培育的马修血吸虫×埃及血吸虫杂交F1相同，但也可能代表马修血吸虫×莱氏血吸虫杂交种。需要进一步研究以阐明模式B 的起源。
