Updates on the Cronobacter Genus
Annual Review of Food Science and Technology ( IF 12.4 ) Pub Date : 2018-03-26 00:00:00 , DOI: 10.1146/annurev-food-030117-012246

There has been considerable concern related to Cronobacter spp. in foods, especially due to their highlighted association with neonatal infections through the ingestion of reconstituted powdered infant formula (PIF). This concern resulted in improved microbiological criteria recommendations by the Codex Alimentarius Commission and revised WHO advice on the preparation of infant feeds. In recent years, the diversity of the genus has been well described, and various detection and typing methods have been developed. This review considers our current knowledge of the genus and how DNA-sequence-based methods have contributed considerably to research into improved detection methods and more reliable identification procedures, genotyping schemes, and genomic analysis. The broader occurrence of Cronobacter in food ingredients, finished products, and food manufacturing environments is covered. This review also highlights the significance of clonal lineages in microbial source tracking and the use of CRISPR-cas array profiling.

克罗诺杆菌属的更新

Cronobacter spp有关的问题引起了相当大的关注。尤其是由于它们通过摄入重构粉状婴儿配方食品(PIF)与新生儿感染密切相关。这种担忧导致食品法典委员会改进了微生物标准建议,并修订了世卫组织关于婴儿饲料制备的建议。近年来,已经很好地描述了属的多样性,并且已经开发了各种检测和分型方法。这篇评论考虑了我们目前的属知识,以及基于DNA序列的方法如何为改进检测方法和更可靠的鉴定程序,基因分型方案和基因组分析的研究做出了巨大贡献。更广泛的发生食品成分,最终产品和食品生产环境中的克罗诺杆菌均涉及在内。这篇综述还强调了克隆谱系在微生物来源追踪和CRISPR- cas阵列谱分析中的重要性。
