Abstract
We report Trypanosoma cruzi infection rates of the native kissing bug Triatoma protracta in southern California. The rates are within the historically reported range, but differ significantly between the two sites (19% in Escondido and 36% in Glendora). Identification of T. cruzi in T. protracta was conducted for the first time by using partial 18S ribosomal RNA and 24Sα ribosomal RNA sequences. Incongruence of 24Sα ribosomal RNA phylogeny with current T. cruzi genotype classification supports non-clonality of some T. cruzi genotypes.
摘要
我们报告了加利福尼亚州南部本地接吻虫 Triatoma protracta 的克氏锥虫感染率。这些比率处于历史报告范围内，但在两个地点之间有显著差异（埃斯孔迪多为 19%，格伦多拉为 36%）。首次使用部分 18S 核糖体 RNA 和 24Sα 核糖体 RNA 序列对 T. protracta 中的 T. cruzi 进行了鉴定。24Sα 核糖体 RNA 系统发育与当前 T. cruzi 基因型分类的不一致性支持了某些 T. cruzi 基因型的非克隆性。
