摘要/Abstract

摘要： 动物寄生性线虫与其共生菌的相互关系是防控该类寄生虫的关键和基础。随着宏基因组测序、生物信息学分析以及细菌分离培养技术的不断发展，动物寄生性线虫与其共生菌间的复杂关系正逐渐被人们揭示。研究表明，动物寄生性线虫与其共生菌群间存在诸如营养互济、免疫互作、生态位效应等密切关系，这些互利互惠关系促进二者在宿主体内的共存。然而受目前试验目的、实验技术、宿主与动物寄生性线虫种类不同等因素影响，有关动物寄生性线虫与其共生菌相互关系的研究十分零散，缺乏系统、全面的归纳、分析和总结。为此，本论文拟结合现有最新文献知识，对动物寄生性线虫与其共生菌关系研究现状和进展进行综述，以期增加人们对该领域的认识和了解，并为发现新的寄生虫疾病干预措施提供信息参考。

Abstract: The relationships between animal-parasitic nematodes and their symbiotic bacteria are the key and basis for the prevention and control of these parasites. With the development of metagenomic sequencing, bioinformatics analysis, bacterial isolation and culture technology, the complex relationships between animal-parasitic nematodes and their symbiotic bacteria are gradually being unveiled. Studies showed the close relationships between parasitic nematodes and their symbiotic bacteria including nutrient interaction, immune interaction and niche effect, which promote their coexistence in same hosts. However, because of experimental purposes, experimental techniques and animal host specificity of parasitic nematodes, studies on relationships between parasitic nematodes and their symbiotic bacteria are few and scattered, and a systematic and comprehensive review is still lacking so far. Therefore, this review aims to summarize the latest research progress on relationships between animal-parasitic nematodes and their symbiotic bacteria based on current literature knowledge to increase the knowledge and understanding of this field and provide information reference for the discovery of new interventions for parasitic nematodes.

Key words: nematodes, symbiotic microorganisms, interactions, parasitism and mutual benefit, intervention strategies
