Abstract

We evaluated Trypanosoma cruzi infection rates by means of minicircle DNA-based polymerase chain reactions (PCRs) in 70 starved Mepraia gajardoi from northern Chile and 65 M. spinolai from central Chile after feeding. Immediately after collection in the field, 20% of M. gajardoi were found infected; after feeding, 67% of the uninfected were infected. One group of M. spinolai seemed to be completely uninfected, but after the first and second feedings, 62% and 59% were positive, respectively.

摘要

我们通过基于微小环DNA的聚合酶链反应（PCR）评估了来自智利北部的70只饥饿的盖氏梅氏锥蝽和来自智利中部的65只饱腹的斯氏梅氏锥蝽的克氏锥虫感染率。在野外采集后立即检测发现，20%的盖氏梅氏锥蝽已被感染；喂食后，67%未感染的锥蝽被感染。一组斯氏梅氏锥蝽似乎完全未被感染，但在第一次和第二次喂食后，阳性率分别为62%和59%。
