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
