克氏锥虫是恰加斯病的原生动物病原体,其种群结构复杂,由多个菌株组成,具有不同的生态流行病学分布。寄生虫的遗传变异性可能与疾病结果有关,因此强调有必要开发克氏锥虫体内分型方法。血清学分型方法利用宿主抗体的存在来对抗多态寄生虫抗原,成为解决这一问题的一种有吸引力的方法。这些技术是可靠的、简单的、具有成本效益的,并且不受现有基因分型方法固有的方法学/生物学限制。在这里,我们批判性地评估克氏t型血清分型的进展,并讨论高通量免疫组学提供的机会,以改善这一领域。
Trypanosoma cruzi, the protozoan agent of Chagas disease, displays a complex population structure made up of multiple strains showing a diverse eco-epidemiological distribution. Parasite genetic variability may be associated with disease outcome, hence stressing the need to develop methods for T. cruzi typing in vivo. Serological typing methods that exploit the presence of host antibodies raised against polymorphic parasite antigens, emerge as an appealing approach to address this issue. These techniques are robust, simple, cost-effective and not curtailed by methodological/biological limitations intrinsic to available genotyping methods. Here, we critically assess the progress towards T. cruzi serotyping and discuss the opportunity provided by high-throughput immunomics to improve this field.
