Summary: Although medicinal herbs and plants do not show strong in vitro antagonism and in vivo disease resistance towards lactococcosis agents in aquaculture, essential oils containing thymol or carvacrol have been found to be more effective. In vivo studies have shown moderate efficacy of extracts in reducing mortality in infected animals and improving immune parameters. Further research is required to fully understand the potential of medicinal herbs in combating lactococcosis.

Summary: This study investigated lactococcosis outbreaks in Nile tilapia on Brazilian farms and characterized the isolates through multilocus sequence typing (MLST), virulence to Nile tilapia, and antimicrobial susceptibility. The pathogenicity of L. petauri to Nile tilapia was confirmed, and its rapid expansion was observed. Provisional epidemiological cutoff values were determined for L. petauri for six antimicrobial agents from different drug classes.

Summary: Lactococcus garvieae is a well-known pathogen in fish and rarely causes infections in humans and other mammals. This study presents the complete genomic sequence of a clinical L. garvieae strain and compares it with other genomes. The results show that L. garvieae is a highly recombinogenic species with horizontal gene transfers comprising nearly 30% of its genome.

Summary: The purpose of this study is to analyze existing studies related to demoralization through bibliometrics. Relevant literature on demoralization was searched from various databases, and bibliometric analysis was conducted to explore publication trends, author-country collaboration, research hotspots, and future trends. The results showed that there has been a significant increase in research on demoralization since 2000, with the United States being the leading country in terms of publications. There is active collaboration among leading scholars, and major research hotspots include assessing demoralization, demographics and psychological disorders in different disease contexts, and the association and distinction of diverse clinical psychological abnormalities. The impact of COVID-19 on demoralization and subsequent interventions and psychological care may become a future research direction.

Summary: Emerging plant pathogens have increased significantly in the past century. Through genetic analysis, this study provides insights into the genetic relationships, spread pathways and evolutionary history of Phellinus noxius. The study suggests that recent emergence of this pathogen in eastern Asia, Australia and the Pacific Islands has likely been driven by both human activities and natural disturbances.

Summary: The study investigated the drug susceptibility and resistance mechanism of antibiotic-resistant pathogenic strains of Lactococcus garvieae serotype II isolated from fish in Japan. The strains showed resistance to erythromycin, lincomycin, and tiamulin, with PCR amplification confirming the presence of the erm(B) gene in all erythromycin-resistant strains. The study also identified a plasmid, pkh2101, in an erythromycin-resistant strain, which shared high similarity with the plasmid pAMbeta1 previously isolated from Enterococcus faecalis DS-5.

Summary: Canine circovirus has been identified recently as a virus affecting both foxes and dogs, with a circulation rate of 2-5% in the Alps region of Northern Italy. Genetic isolation in Alps foxes may prevent frequent transmission events to domestic dogs, possibly due to independent evolution within the fox population. Furthermore, strains of CanineCV in Italian foxes are unexpectedly related to those in the United Kingdom and Scandinavian area, suggesting a long-standing coexistence with the virus in European fox populations.

Summary: This study provides a global assessment of the potential spread of naturalized plants, birds, and mammals to different terrestrial regions. It predicts that there is a significant potential for further spread of naturalized birds in North America, mammals in Eastern Europe, and plants in North America, Eastern Europe, and Australia. The study also identifies introduction history, dispersal, and the spatial distribution of suitable areas as key factors influencing species spread. Natural dispersal plays a more important role in bird spread compared to plant spread, and the transportation by humans is a significant factor in plant spread. However, there are still unanswered questions, particularly regarding the lack of occupation of climatically suitable areas by many birds in North America.

Summary: How hosts respond to and cope with infectious agents can change the environment and alter selective pressures and evolutionary trajectories. However, the understanding of how ecology and (co)-evolution shape disease in natural communities remains limited. This theme issue integrates empirical and field studies from various taxa and ecosystems to shed light on the eco-evolutionary dynamics of host-parasite interactions. The key take-aways are the need for more research in multi-species contexts and the promising advancements and foundational studies that provide a roadmap for understanding eco-evolutionary dynamics in natural settings.

Summary: The PDO designation ensures the traceability and restricted geographical area of food production. However, the sensory qualities of dairy products with the same PDO differ between manufacturers. This study analyzed the microbiome of raw milk cheeses in Italy and found that the microbial communities and use of site-specific Natural Whey Cultures (NWCs) had a significant impact on the organoleptic features and bioactive compounds of the cheeses. These findings suggest the need to revise the PDO designation to consider the site-specific microbial metabolism and guarantee the desired qualities of the final product.

Summary: During infancy, assessing the diversity of gut microbiota in newborns and its association with health and disease is crucial. This study identified eight major Infant Community State Types (ICSTs) dominated by 17 bacterial taxa, which corresponded to geographical origin and infant health status. The study also revealed patterns of multistrain coexistence among ICSTs and provided insights into the mechanistic aspects of the health-gut microbiota interplay in newborns through metagenomic and metatranscriptomic analyses.

Summary: Based on the shotgun metagenomic sequencing data of 12,415 fecal microbiomes, this study reveals the strain-level dynamic changes in the gut microbiota across the human life span. It demonstrates the host sex-related persistence of strains belonging to common maternally-inherited species, such as Bifidobacterium bifidum and Bifidobacterium longum subsp. longum. Comparative genome analyses and experiments suggest that host-glycan metabolism-related bacterial glycosyl hydrolases may contribute to more efficient colonization in females compared to males. These findings indicate an intriguing ancient sex-specific host-microbe coevolution that drives the selective persistence of key microbial taxa in women.

Summary: This study aimed to assess gender differences in gastric bacterial microbiota between subjects with healthy stomachs and those with autoimmune atrophic gastritis. Results showed that women with healthy stomachs had a higher gastric bacterial abundance and less microbial diversity compared to men. Autoimmune atrophic gastritis seems to reset gender differences in gastric bacterial abundance and reduce biodiversity in males.
