Myxobolus lentisuturalis is an important Myxozoa pathogen of fish.The parasite could cause varying degrees of damage to its hosts and bring serious economic losses to aquaculture.To further understand the pathogenic and parasitic characteristics of Myxobolus lentisuturalis,the present study reviews the research progress of Myxobolus lentisuturalis,describes its morphological characteristics and life history,and discusses the pathogenicity and immunological characteristics of Myxobolus lentisuturalis.Due to the lack of research on Myxobolus lentisuturalis,the threat of Myxobolus lentisuturalis to fish culture is increasingly emerging,and effective prevention and control measures are urgently needed.Therefore,the purpose of this paper is to accumulate basic data for pathogen identification and control of Myxobolus lentisuturalis.
