The effect of Trypanosoma brucei and T vivax on the ejaculate of sheep and the rate of recovery with diminazene aceturate treatment was investigated. Animals were made to ejaculate once a week before infection, during infection and after treatment. Parameters studied were semen volume, semen colour, sperm motility and concentration, percentage dead spermatozoa and sperm morphology. Both infections severely affected the quality of the ejaculate although in T vivax infection there was no appreciable change in semen volume and sperm concentration. There was a reduction in sperm motility and concentration, an increase in the percentage of dead spermatozoa and in abnormal sperm morphology. Treatment led to improvement in all parameters but recovery was faster in T vivax than in T brucei infection. Ejaculate with few primary abnormalities was not obtained until 19 weeks after treatment.
研究了布氏锥虫和间日锥虫对绵羊精液的影响以及用乙酰氨基苯脒治疗后的恢复率。在感染前、感染期间和治疗后，让动物每周射精一次。研究的参数包括精液体积、精液颜色、精子活力和浓度、死精子百分比以及精子形态。两种感染均严重影响精液质量，不过在间日锥虫感染中，精液体积和精子浓度没有明显变化。精子活力和浓度降低，死精子百分比和异常精子形态增加。治疗使所有参数都有所改善，但间日锥虫感染的恢复速度比布氏锥虫感染更快。直到治疗后19周才获得原发性异常较少的精液。
