Summary: This study investigates the genetic differences and evolution of the most common fish pathogen Vibrio anguillarum serotype O1. The O1 strain has two chromosomes and two typical plasmids. Furthermore, the O1 strain displays resistance to colistin sulphate, which differs from the O2 serotype and may be attributed to the ugd gene. The study also reveals that the genetic heterogeneity in the O-antigen biosynthesis gene cluster is characterized by the absence or presence of unique genes, which could result in differences in immune evasion mechanisms among serotypes.

Summary: In this study, exosomes were isolated from Vibrio harveyi and Vibrio anguillarum using a supercentrifugation method, and their protein compositions were analyzed. The exosomes of these two vibrios contained virulence factors and also played roles in important bacterial activities. Further experiments confirmed the involvement of exosomes in vibrio toxicity. This study provides a valuable proteome database for understanding the pathogenic mechanisms of vibrios from the exosome perspective.

Summary: This study analyzed the pathogenicity and genomic features of nine vapN-harboring R. equi isolated from human patients with and without HIV/AIDS. Some strains showed significant VapN production and lethally pathogenic effects in mice, reproducing necrotizing granulomatous inflammation. Whole genome sequences were determined for all strains, revealing differences in VapN production among nearly identical pVAPN types, highlighting the need for further investigation into the VapN expression mechanism.

Summary: The study investigated the phenotypic characterization and antimicrobial susceptibility patterns of 54 V. harveyi strains collected from Larimichthys crocea in China. The isolates displayed resistance to a variety of antibiotics and carried multiple virulence genes. Additionally, a novel V. harveyi-specific phage with broad host range was discovered and showed high efficacy in preventing and controlling V. harveyi infection in a zebrafish model.

Summary: This study characterized the virulence factor repertoire of V. parahaemolyticus strain LC, which showed significant virulence to shrimp Litopenaeus vannamei. The results revealed the presence of specific genes associated with shrimp and human pathogenic strains, as well as unique mobile genetic elements-borne virulence factors. V. parahaemolyticus demonstrates host-specific virulence, contributing to the origin and spread of pathogenic factors.

Summary: Lasiodiplodia theobromae is an important pathogen that attacks over 500 plant species, and the incidence of diseases associated with it is increasing due to global warming and climate change. Genome sequencing and comparative genomics analysis revealed variations in virulence-related genes in different L. theobromae isolates, potentially explaining the differences in their pathogenicity.

Summary: The study demonstrates that hosts exhibit different immune responses when encountering Vibrio pathogens of varying virulence, including activation of different immune pathways. Highly virulent Vibrio strains induce apoptosis in oyster cells, while less virulent strains enhance phagocytosis and cell adhesion capabilities.

Summary: The study investigated how Vibrio anguillarum adapts to stress conditions related to vibriosis through proteomic analysis, revealing specific protein adaptations under different stresses. Iron deprivation and exposure to Atlantic salmon serum led to upregulation of iron acquisition mechanisms in VA. The findings provide insights into potential virulence determinants and can improve intervention strategies for controlling vibriosis in aquaculture.

Summary: Pathogen emergence is a complex phenomenon that is poorly understood, particularly in terms of the genetic traits and environmental factors that contribute to the pathogenic potential of specific strains. The distribution of unique genetic markers and clusters in different ecological locations highlights the influence of biotic and abiotic factors in shaping pathogen emergence. Understanding these relationships can aid in assessing and preventing future outbreaks.

Summary: The laboratory attenuated Babesia bigemina strain lost virulence for the bovine host and the capacity for being transmitted by the tick vector. Only five out of 27 virulence genes identified in the virulent strain were fully present in the attenuated strain, suggesting a continuous partial loss of virulence genes in the laboratory strain.

Summary: The study found a diversity of pigmented bacterial symbionts in corals from Abrolhos Bank, Brazil, which exhibited strong antioxidant activity and had similar pigment patterns and carotenoid gene clusters. This suggests that the bacterial symbionts may play important roles in the antioxidant capacity of Montastraea and Mussismilia holobionts.

Summary: Infectious diseases, such as white plague-like disease, have been identified as a major factor contributing to coral reef decline globally. The study on the gene expression profiles of Mussismilia braziliensis affected by WPL revealed repression of immune system and cellular defense processes in WPL samples, as well as seasonal variation in transcription. Analysis of active bacterial rRNA indicated dysbiosis in WPL-affected M. braziliensis, with the loss of potentially symbiotic bacteria and proliferation of opportunistic microbes.

Summary: Aquimarina litoralis CCMR20, originating from the coral Mussismilia braziliensis, has a genome size of 6.3 Mb, 32.6% GC, and 5513 genes. Genomic analysis revealed genes related to symbiosis, including heterotrophic carbon metabolism, CAZymes, B-vitamins, carotenoid pigment, and antioxidant molecules production. The genetic evidence suggests a potential relevance of this symbiont in the health of Mussismilia holobionts.

Summary: The article describes four new species of Crellidae and discusses their relationships based on published molecular phylogenies. The new species differ from each other and known species mainly due to their spiculation. Chelae microscleres and acanthostyles may be used to infer phylogenetic relationships and verify the monophyly of Crella Gray, 1867 and Crellidae.
