Microbiome Dynamics in a Shrimp Grow-out Pond with Possible Outbreak of Acute Hepatopancreatic Ne...

Although AHPND is known to be caused by pathogenic Vibrio parahaemolyticus hosting the plasmid-related PirABvp toxin gene, the effects of disturbances in microbiome have not yet been studied.
虽然已知AHPND是由携带与质粒相关的PirABvp毒素基因的致病性副溶血性弧菌引起的，但微生物群对疾病干扰的影响尚未进行研究。

The microbiomes of pond seawater and shrimp stomachs underwent varied dynamic succession during the period.
在此期间池塘海水和虾肠道微生物经历了不同的动态演替。

AHPND markedly changed the bacterial diversity in the stomachs; it decreased the Shannon index by 53.6% within approximately 7 days, shifted the microbiome with Vibrio and Candidatus Bacilloplasma as predominant populations, and altered the species-to-species connectivity and complexity of the interaction network.
AHPND明显改变了胃内细菌的多样性;约7天内香农指数下降53.6%，以弧菌和念珠菌为优势种群的微生物群落发生转移，改变了交互网络的种间连通性和复杂性。

The AHPND-causing Vibrio species were predicted to develop a co-occurrence pattern with several resident and transit members within Candidatus Bacilloplasma and Cyanobacteria.
引起AHPND的弧菌种类预计与念珠菌和蓝细菌内的几个常驻和过境成员共同发生模式。

This study’s insights into microbiome dynamics during AHPND infection can be valuable for minimising this disease in shrimp farming ponds.
本研究对AHPND感染过程中微生物群落动态变化的研究对于减少虾池中该病的发生具有重要价值。
