spp. is responsible for several food and waterborne disease outbreaks worldwide. Healthier lifestyles attract consumers to eat, notably, fresh food like fruits and vegetables. The consumption of raw or under-cooked food increases the risk of foodborne transmission of Cryptosporidiosis. The assessment of the consumer's exposure to danger is crucial for public health. Still, the standardized method to detect this parasite in fresh leafy greens and berry fruits has only been available since 2016 and suffers from weaknesses. Consequently, in this study, we propose a method with minimum processing steps that combines cell culture and the quantitative PCR (CC-qPCR) for detecting infectious oocysts recovered from lamb's lettuce. This CC-qPCR is a rapid and easy method that can detect up to one oocyst, whereas it is undetectable by classic qPCR.
隐孢子虫属在全球范围内引发了多起食源性和水源性疾病暴发。更健康的生活方式吸引消费者食用,特别是水果和蔬菜等新鲜食物。食用生的或未煮熟的食物会增加隐孢子虫病食源性传播的风险。评估消费者接触危险的情况对公共卫生至关重要。然而,用于检测新鲜绿叶蔬菜和浆果中这种寄生虫的标准化方法直到2016年才出现,并且存在缺陷。因此,在本研究中,我们提出了一种处理步骤最少的方法,该方法结合细胞培养和定量PCR(CC-qPCR)来检测从羊生菜中回收的感染性卵囊。这种CC-qPCR是一种快速简便的方法,最多可检测到一个卵囊,而传统qPCR则无法检测到。
