A twelve-month survey in three Local Government Areas (LGA) in Nsukka zone, Anambra State, Nigeria revealed that out of 150 local and exotic breeds of pig examined, 46 (30.7%) were infected with trypanosomes. Both single and mixed infections of Trypanosoma brucei and T. congolense were observed. However, T. brucei was the predominant trypanosome encountered. The husbandry system in practice was the most significant factor influencing the prevalence of trypanosomes in the pigs. In addition significantly higher prevalences were recorded during the rainy seasons. Clinical trypanosomosis was encountered in only eight of the 46 positive cases seen, with anaemia, loss of weight and anoestrus being the most important effects associated with these infections. The pathogenic and economic significance of these findings are discussed.
在尼日利亚阿南布拉州Nsukka区的三个地方政府区域（LGA）进行的为期12个月的调查显示，在检查的150个本地和外来猪品种中，有46头（30.7%）感染了锥虫。观察到布氏锥虫和刚果锥虫的单一感染和混合感染。然而，布氏锥虫是最常见的锥虫。实际的饲养系统是影响猪群中锥虫流行率的最重要因素。此外，在雨季记录到的流行率明显更高。在所见的46例阳性病例中，只有8例出现临床锥虫病，贫血、体重减轻和发情期停止是与这些感染相关的最重要影响。讨论了这些发现的致病和经济意义。
