Susceptibility of Tambaqui ( Colossoma macropomum) to Nile Tilapia-Derived Streptococcus agalactiae and Francisella orientalis. Microorganisms 2024; 12:2440.

Abstract
Nile tilapia (Oreochromis niloticus) and tambaqui (Colossoma macropomum) are the two most produced freshwater fishes in Brazil. This study investigated the potential pathogenicity of Streptococcus agalactiae and Francisella orientalis, previously isolated from diseased Nile tilapia, to tambaqui. Experimental infection trials were conducted in juvenile tambaqui at a dose of approximately 107 CFU fish-1, assessing clinical signs, mortality, bacterial recovery, and histopathological changes. Results demonstrated that S. agalactiae exhibited high pathogenicity to tambaqui, causing rapid disease progression, high mortality (83.33%) within 48 h post-infection, and severe lesions in multiple organs, under the experimental conditions. In contrast, F. orientalis infection did not result in mortality or clinical signs, despite bacterial recovery and granulomatous inflammation observed in the tissues. This study highlights the need to consider the potential impact of these pathogens in tambaqui farming.

Zhang W, Qian Z, Ji J, Wang T, Yin S, Zhang K. Characterization of HSP70 and HSP90 Gene Family in Takifugu fasciatus and Their Expression Profiles on Biotic and Abiotic Stresses Response. Genes (Basel) 2024; 15:1445. [PMID: 39596645 PMCID: PMC11593546 DOI: 10.3390/genes15111445] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2024] [Revised: 10/24/2024] [Accepted: 11/06/2024] [Indexed: 11/29/2024] Open
Abstract
BACKGROUND Heat shock proteins (HSPs) play crucial roles in response to temperature changes and biotic stresses. However, the HSP gene family in the pufferfish (Takifugu fasciatus) herring has not been comprehensively investigated. METHODS AND RESULTS This study presents a systematic analysis of the HSP70 and HSP90 gene families in T. fasciatus, focusing on gene characterization, conserved structural domains, molecular evolutionary history, and expression patterns of the HSP gene family under stress conditions. The findings reveal that 16 HSP genes are evolutionarily conserved, while hspa4 and hsp90aa appear specific to teleost fish. HSP genes exhibit widespread expression across 11 examined tissues, with most demonstrating high expression levels in the heart, brain, and liver. Furthermore, T. fasciatus was subjected to cryogenic and biotic stresses, revealing distinct expression patterns of HSPs under various stress conditions. The response of HSPs to cold stress and Aeromonas hydrophila infection was sustained. In contrast, gene expression of HSPs significantly changed only in the pre-infection period following Ichthyophthirius multifiliis infection, gradually returning to normal levels in the later stages. CONCLUSIONS These experimental results provide a foundation for further in-depth investigations into the characteristics and functions of HSPs in T. fasciatus.
