“…The inflammatory response observed in the periocular tissue, epicardium, coelomic adipose and gill supports systemic dissemination of bacterial organisms and/or their toxic products likely via a hematogenous route. While not pathognomonic for piscine Edwardsiellosis, the hyperplastic and necrotizing branchitis are consistent with reports of E. piscicida infection in other temperate, freshwater fishes (Fogelson et al, ; Griffin et al, ; Camus, Griffin, Armwood, & Soto, ).…”

“…In tilapia, E. tarda is described as a pyogranulomatous disease affecting multiple tissues, with necrotizing meningitis, encephalitis and vasculitis (Iregui et al, ). E. ictaluri in Nile tilapia and E. piscicida in largemouth bass produce similar multi‐organ necrosis and granulomas with intracellular bacterial rods (Camus, Griffin, Armwood, & Soto, ; Soto et al, , ). In channel and hybrid catfish, E. ictaluri and E. piscicida can produce granulomatous meningoencephalitis that erodes through a fontanelle in the dorsal cranium causing a haemorrhagic ulcer, the so‐called “hole‐in‐the‐head” lesion (Griffin et al, ; Hawke & Khoo, ).…”

“…Although the infection of E. piscicida in largemouth bass ( Micropterus salmoides ) Camus, Griffin, Armwood, & Soto (2019), zebrafish ( Brachydanio rerio ) (Wang et al, 2019) and goldfish ( Carassius auratus ) (Choe et al, 2017) have been reported, until now, molecular studies on the immune response to E. piscicida in the C. striata remain rare. In this study, we firstly analysed the liver transcriptome profile of the C. striata after E. piscicida infection and obtained the gene information.…”

The Centropristis striata is an important economically marine fish and facing a serious threat from various pathogens. Edwardsiella piscicida is one of the fish pathogens that seriously infect cultured and wild fish species. To understand the molecular immune mechanisms underlying the response to E. piscicida, a comparative gene transcription analysis was performed through RNA‐Seq technology. The low‐quality sequences were excluded, and the high‐quality sequences were assembled into a total of 60,759 contigs with an average length of 988.95 bp. A gene ontology (GO) analysis was employed to classify 5744 genes according to three major functional categories: molecular function, cellular component and biological process. A total of 19,918 genes were successfully annotated into 26 functional categories according to the clusters of orthologous groups (COG) classification. Furthermore, 15,006 genes were classified into 332 KEGG pathways. The q‐value was introduced to estimate 5109 genes significantly differentially expressed which includes 1781 up‐regulated genes and 3328 down‐regulated genes. The differentially expressed genes were involved in the major immune‐related pathways which refer to the pathogen recognition, inflammation, Toll‐like receptor and chemokine signalling pathways. Moreover, 24,487 potential simple sequence repeats (SSRs) and 193,760 candidate single nucleotide polymorphisms (SNPs) were detected and identified in the C. striata liver transcriptome. This work not only provides a valuable resource for further understanding of the antibacterial molecular mechanism of C. striata but also contributes to facilitate future studies on gene expression and functional genomics.
