蜡样芽孢杆菌检测方法的研究进展

Research progress on detection methods of Bacillus cereus

蜡样芽胞杆菌(Bacillus cereus)是革兰氏阳性芽孢杆菌,广泛存在于自然环境中,对不良环境有较强的抵抗力,是一种人畜共患的食源性条件致病菌。蜡样芽孢杆菌能够产生多种毒素,这些毒素决定了其致病性。因此,建立快速、准确的蜡样芽孢杆菌检测方法对疾病的诊断和发病后的及时治疗至关重要。本文对近年来检测蜡样芽孢杆菌的菌体与毒素的方法进行了全面的总结,主要是对各方法的原理、检测范围、优缺点等进行比较,并探讨新方法的可行性,以期为科学检测、鉴定蜡样芽孢杆菌提供依据和思路。

Bacillus cereus is a Gram-positive bacillus,which widely exists in the natural environment and has strong resistance to adverse environment.It is a kind of foodborne conditional pathogen that affects both humans and animals.Bacillus cereus can produce a variety of toxins that determine its pathogenicity.Therefore,the establishment of a rapid and accurate method for the detection of Bacillus cereus is very important for the diagnosis and timely treatment of the disease.This paper comprehensively summarizes the methods of detecting bacteria and toxins of Bacillus cereus in recent years,mainly compares the principle,detection range,advantages and disadvantages of each method,and discusses the feasibility of the new method,with a view to scientific provide basis and ideas for detection and identification of Bacillus cereus.
