Summary: In this study, the researchers found that the T4SS of Yersinia ruckeri SC09 mediated bacterial virulence and immune evasion, possibly through the secretion of molecules such as STIR-1, STIR-2, and STIR-3. These findings contribute to a better understanding of the general rules of bacterial pathogenicity.

Summary: The use of enrofloxacin in trout farms for the treatment of yersiniosis should be reevaluated, as a single intraperitoneal injection of ENR at 10 mg/kg appears to be more effective than repeated oral administrations. This study suggests the need for revising the oral doses used in trout farms.

Summary: The study explored the effects of Greek juniper extract on immune responses of rainbow trout, showing that the extract had various impacts such as increasing lysozyme activity, decreasing myeloperoxidase activity, and up-regulating interleukins. Additionally, the juniper extract demonstrated a protective effect against Yersinia ruckeri, leading to a higher survival rate in rainbow trout treated with it.

Summary: This study characterized a strain (NBRC102019) isolated from river sediment and 9 isolates from a disease outbreak. The serotype of NBRC102019 was classified as O-6, while the serotypes of the 9 isolates from the outbreak were all O-7. Multilocus sequence typing revealed that the 9 isolates belonged to the same genotype, distinct from NBRC102019. Challenge tests showed that the outbreak isolates caused substantial mortality in chum salmon, while NBRC102019 did not, indicating a distinct lineage for the Y. ruckeri causing the outbreak.

Summary: This study presents the second update of molecular phylogenetic analysis of Vibrionaceae, adding new insights into the diversity and evolutionary history of this bacterial family. The results show that the classification based on nucleotide sequences of eight housekeeping genes is reliable, and the set of 11 ribosomal protein genes is useful for identifying uncultured species among metagenome-assembled genome pools. This research contributes to taxonomic applications in classifying not-yet-cultured taxa and expanding our understanding of Vibrionaceae.

Summary: This study isolated a Gram-negative, aerobic bacterium named PTE2(T) from laboratory-reared Japanese sea cucumber larvae. Phylogenetic analysis revealed that PTE2(T) was closely related to Thalassotalea sediminis N211(T), but had some differences, indicating the novelty of this strain. Based on genome-based taxonomic approaches, PTE2(T) is proposed as a new species, Thalassotalea hakodatensis sp. nov.

Summary: Strain PT1(T), a rod-shaped bacterium isolated from laboratory-reared larvae of sea cucumber Apostichopus japonicus, demonstrated similarities to Neptuniibacter marinus ATR 1.1(T) and Neptuniibacter caesariensis MED92(T) with sequence similarities of 98.2% and 98.1%, respectively, based on the analysis of 16S rRNA gene nucleotide sequences. However, the average nucleotide identity (ANI) and in silico DNA-DNA hybridization (DDH) values among these three strains were below 95% and 70%, confirming the novel status of PT1(T). Based on the genomic approach, a new species, Neptuniibacter victor sp. nov., is proposed for PT1(T).
