| 英文摘要 | Acute hepatopancreatic necrosis disease (AHPND) outbreaks in cultured shrimps were identified in Zhangpu, China. One Vibrio parahaemolyticus strain PB1937 was isolated from the cultured shrimps and was confirmed as a causative agent of the AHPND outbreak by employing Koch's four postulates. Challenge tests with 10(6) cells ml(-1) of strain PB1937 caused 100% mortality of shrimps, indicating it had sufficient virulence to cause the outbreak. Phylogenomic analysis revealed a clear divergence between PB1937 and 14 publicly available V. parahaemolyticus strains and divided 11 AHPND-causing strains into six genomic clusters. Prophage profiling of above strains revealed strong correlations with their genomic relationship, while Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR) were almost absent in the genomes. The binary toxin gene pirAB(vp) directly related to the development of AHPND was found in a 70-kb plasmid p1937-1 in PB1937 but was absent in a 78-kb novel plasmid p1937-2, which shared 46% sequence similarity with p1937-1. Comparative genomic analysis revealed that PB1937 has a novel truncated type VI secretion system (T6SS1) which possibly affects its antibacterial activity. In addition, three novel genomic islands were reported. The analysis of the genomes gave some clues regarding the correlation of virulence with its genomic trait for the AHPND strains. |
