To gain insights into the prevalence and antimicrobial resistance patterns of major bacterial pathogens affecting largemouth bass (Micropterus salmoides) in Pearl River Delta (PRD) region, Guangdong, China, a study was conducted from August 2021 to July 2022. During this period, bacteria were isolated identified internal organs diseased within PRD region. The 11 antibiotics approved for use aquaculture China analyzed 80 strains Edwardsiella piscicida using microbroth dilution method. results showed that 151 isolates obtained 532 samples, with E. (17.29%, 92/532), Aeromonas veronii (4.70%, 25/532), Nocardia seriolae (2.26%, 12/532) being main pathogens. Notably, accounted highest proportion all bacteria, reaching 60.92% (92/151), mainly occurred November April, accounting 68.48% (63/92) cases. symptoms infected included ascites, enteritis, hemorrhaging tissues organs. drug sensitivity rates ciprofloxacin, sulfonamides, thiamphenicol, florfenicol, enrofloxacin, doxycycline, flumequine, neomycin 96.25%, 60–63%, 56.25%, 43.75%, 40%, 32.5%, 16.25%, 1.25%, respectively. In addition, 76.25% (61/80) these demonstrated more than two types antibiotics. Cluster analysis revealed 23 antibiotic (A–W) among isolates, which clustered groups. Therefore, tailored treatment based on regional is essential effective disease management. findings indicate event an infection bass, neomycin, flumequine are viable options. Alternatively, one may choose drugs as determined by clinical testing.

Background/Objectives: The largemouth bass (Micropterus salmonides) is a farmed fish of significant economic value, and studying its adaptability crucial for enhancing the benefits aquaculture. changes gene expression pattern to rapidly adapt environmental maintain normal physiological function. Methods: In this study, from two distinct backgrounds—Huzhou Xingtai—were used as experimental materials, they have significantly different breeding conditions. Comparative transcriptomics was analyze patterns in both backgrounds. Results: female, there were 1678 differentially expressed genes, which 541 upregulated 1137 downregulated. Meanwhile, male, 1287 including 542 genes 745 downregulated genes. mainly enriched biological processes such metabolic process, regulation, response stimulus, developmental signaling, reproduction immune system process. pathways included carbon metabolism, glycolysis/gluconeogenesis, purine biosynthesis amino acids, starch sucrose fructose mannose pyrimidine MAPK signaling pathway, spliceosome, protein processing endoplasmic reticulum, ribosome biogenesis eukaryotes, etc. Conclusions: We speculated that Xingtai may environment by downregulating metabolism- reproduction-related altering immune-related Our study provided molecular evidence adaptation research scientific basis optimizing technology.
