微生物菌群培养组学在动物医学中的应用

doi:10.11843/j.issn.0366-6964.2020.12.004

摘要/Abstract

摘要： 实验室条件下可培养的微生物约占自然界中微生物总数的1%，这限制了人们对99%未知微生物的认识和利用，而研究表明，那些“不可培养的微生物”是可以被开发和利用的，未能被纯培养的微生物才是未知微生物的主体。微生物培养组学探索利用多种培养条件和长时间的培养，结合基质辅助激光解吸电离飞行时间质谱法（MALDI-TOF-MS）和16S核糖体RNA（rRNA）测序可以大规模鉴定各种微生物，同时利用全基因组测序和宏基因组测序手段对未知微生物进行深入分析。本文综述了国内外近年来微生物菌群培养组学在反刍动物胃肠道、禽类盲肠及家畜鼻腔微生物菌群研究中的最新进展，探讨将动物体内菌群培养组学方法应用于动物疾病防治领域的可行性。作为一个新兴的研究方法，尽管该培养组学还存在一些不够成熟的方面，但它的发展前景十分广阔，微生物菌群培养组学方法和其他研究方法的互补已经逐渐成为发展兽医微生物学新的突破口。

Abstract: Under laboratory conditions, the number of cultured microorganisms accounts for about 1% of the total number of microorganisms in nature, which limits people's understanding and utilization of 99% of the unknown microorganisms. However, relevant researches show that those "uncultured microorganisms" can be developed and utilized, and the uncultured microorganisms are the main body of the unknown microorganisms. The microbial culturomics explored the application of multiple culture conditions and long-term culture, it was combined with Matrix-Assisted Laser Desorption/Ionization Time of Flight Mass Spectrometry (MALDI-TOF-MS) and 16S ribosomal RNA (rRNA) sequencing to identify all kinds of microorganisms on a large scale. At the same time, whole-genome sequencing (WGS) and Metagenomics sequencing technology were used to analyze unknown microorganisms in depth. In this paper, the latest progress of culturomics in the ruminant gastrointestinal tract, poultry cecum, and livestock nasal microflora in recent years was reviewed, and the feasibility of applying the method of microflora culturomics in animal disease prevention and control was discussed. As a new research idea, culturomics has some immature aspects, but its development prospect is very broad. The complementary of microflora culturomics and other research methods have gradually become a breakthrough in the development of veterinary microbiology.

Key words: culturomics, MALDI-TOF-MS, 16S rRNA, genome sequencing, rumen microflora, cecal gut microflora, nasal microbiota
