目的评估非洲不同地区舌囊肿阳性猪和抗原阳性猪的患病率之间的关系，评估是否可以将检查猪的包囊作为一种快速监测工具，用于识别囊尾蚴病高传播概率较高的地理区域。语言和血清学检查。研究地点位于非洲10个国家。结果血清阳性率范围从4%到41%。尽管不同的研究地点，这两个变量之间的关系是高度一致的，并建议识别舌囊肿可能是有用的囊虫病监测。我们发现所有超过10%的猪舌头上有囊肿的地区都有至少30%的血清阳性率（PPV为100%），尽管该截止值在预测低传播区域时不太可靠结论评估舌囊阳性猪的流行率是一种潜在的快速流行病学工具，可用于确定囊尾蚴病的高风险地区，尽管需要使用标准化数据集进行进一步的完善和验证。
OBJECTIVE To assess the association between the prevalence of tongue cyst-positive and antigen-positive pigs across different settings in Africa, to evaluate whether examining pigs for cysts could be used as a rapid surveillance tool for identifying geographical areas with a higher probability of high transmission of cysticercosis.METHODS Published data were collated from 26 study sites across Africa that reported the prevalence of porcine cysticercosis by both lingual and serological examinations. The study sites were located in 10 countries across Africa.RESULTS Seroprevalence rates ranged from 4% to 41%. Despite the varied study sites, the relationship between the two variables was highly consistent and suggests identification of tongue cysts may be useful for cysticercosis surveillance. We found that all areas with more than 10% of pigs having cysts in their tongues had at least 30% seroprevalence (PPV of 100%), although this cutoff is less reliable at predicting that an area is of low transmission (NPV of 84%).CONCLUSION Assessing the prevalence of tongue cyst-positive pigs is a potential rapid epidemiological tool for identifying areas at high risk of cysticercosis, although further refinement and validation is required using standardised data sets.
