Leukocyte levels were monitored weekly in chickens infected with the avian schistosome Austrobilharzia variglandis. Changes in relative and absolute numbers of leukocytes were recorded over a 7-week period beginning 1 week before exposure. There was a significant increase (P less than 0.001) in total leukocytes, peaking at 5.8 X 10(4) cells/mm3 on day 21 postexposure; controls had 2.4 X 10(4) cells/mm3 on that day. The leukocyte count declined over the next 3 weeks, returning to nearly normal levels by day 42 postexposure. With the exception of eosinophils, which peaked 35 days postexposure, all leukocyte subpopulations peaked in number on day 21. Increases in heterophils and monocytes were related to the schistosome egg burden.
对感染鸟类血吸虫Austrobilharzia variglandis的鸡每周监测白细胞水平。在暴露前1周开始的7周时间内记录白细胞相对数量和绝对数量的变化。暴露后第21天，白细胞总数显著增加（P<0.001），峰值为5.8×10⁴个细胞/mm³；对照组在该日为2.4×10⁴个细胞/mm³。白细胞计数在接下来的3周内下降，到暴露后第42天恢复到接近正常水平。除了在暴露后35天达到峰值的嗜酸性粒细胞外，所有白细胞亚群的数量在第21天达到峰值。嗜异性粒细胞和单核细胞的增加与血吸虫卵负荷有关。
