对来自小鼠的曼氏链球菌成虫进行了化学吸引研究。为了测试吸引力或排斥力，一些蠕虫对被机械分离，并将个体放置在聚碳酸酯室中。实验在37℃下进行。 C室和室包含透析管烟囱。在所有情况下，当将一只蠕虫而不是两只蠕虫放入烟囱时，就会发生异性吸引。将具有特定MW排除的未穿孔烟囱与穿孔烟囱进行比较，以研究异性吸引力。在使用穿孔烟囱的设计以及具有 50,000 和 12,000 MW 排除的设计中，吸引力相似，但在具有 1000 (MW) 排除的烟囱设计中没有发现任何吸引力。
Chemoattraction studies were done with S. mansoni adults from mice. To test for attraction or repulsion, some worm pairs were separated mechanically and the individuals placed in polycarbonate chambers. Experiments were done at 37.degree. C and chambers contained dialysis tube chimneys. In all cases, heterosexual attraction occurred when one worm, but not 2 worms, were placed in the chimneys. Unperforated chimneys with specific MW exclusions were compared with perforated chimneys to study heterosexual attraction. Attraction was similar in designs using perforated chimneys and those with 50,000 and 12,000 MW exclusions, but none was seen in chimney designs with 1000 (MW) exclusions.
