() is an obligate intracellular apicomplexan protozoan that causes toxoplasmosis. Approximately one-third of the world's population is currently -seropositive. Although most infections are symptomless, a few can produce retinal lesions and, in immunocompromised persons or when congenitally contracted, can progress to life-threatening central nervous system disseminated infections. Therefore, quick, and precise diagnosis is a must. Molecular techniques nowadays play a crucial role in toxoplasmosis diagnosis, particularly in immunocompromised patients or congenital toxoplasmosis. This review aimed to detail recent advancements in molecular diagnostics of infections. The terms "Toxoplasmosis," "Molecular diagnostics," "PCR," "qPCR," "B1," and "rep529" were used to search the English-language literature. In developed nations, conventional PCR (PCR) and nested PCR have been supplanted by quantitative PCR (qPCR), although they are still widely employed in poor nations. The diagnosis of toxoplasmosis has been revolutionized by the emergence of molecular diagnostics. Unfortunately, there is still substantial interlaboratory variability. There is an immediate need for standardization to increase the comparability of results between laboratories and clinical trials.

()是一种专性细胞内顶复门原生动物,可引起弓形虫病。目前全球约三分之一的人口弓形虫血清学检测呈阳性。虽然大多数感染没有症状,但少数感染可导致视网膜病变,在免疫功能低下的人群中或先天性感染时,可发展为危及生命的中枢神经系统播散性感染。因此,快速、准确的诊断至关重要。如今,分子技术在弓形虫病诊断中发挥着关键作用,尤其是在免疫功能低下的患者或先天性弓形虫病的诊断中。本综述旨在详细介绍弓形虫感染分子诊断的最新进展。使用“弓形虫病”“分子诊断”“PCR”“qPCR”“B1”和“rep529”等术语检索英文文献。在发达国家,传统PCR(PCR)和巢式PCR已被定量PCR(qPCR)所取代,不过它们在贫困国家仍被广泛使用。分子诊断技术的出现彻底改变了弓形虫病的诊断方式。不幸的是,实验室间仍存在很大的变异性。迫切需要进行标准化,以提高实验室之间以及临床试验结果的可比性。
