Summary: Vertically transmitted heritable microbial symbionts are important invertebrate biology and ecology. Arsenophonus provides a clear example of symbiotic transmission patterns, with some strains being obligate vertically transmitted symbionts and others having mixed modes of transmission. This research expands the understanding of genetic mechanisms in bacterial-insect interactions and broadens the range of host species infected with nasoniae/apicola clade strains.

Summary: A large number of microorganisms continuously divide in the guts of animals and humans, allowing for real-time observation of microbial evolution. Recent studies have revealed that natural selection shapes within-host evolution in the intestines of mice and humans, with the gut microbiota being highly dynamic and influenced by species diversity. Genetic and bioinformatics tools can help quantify the selection strength on mutations and transfer events in gut ecosystems, providing insights into the drivers and functional consequences of gut evolution. Understanding the rules of intrahost microbiota evolution is crucial for the development of effective microbiota therapies.

Summary: Deep sequencing of viral populations using NGS provides insights into evolution, transmission dynamics, and population genetics, but current practices may overlook valuable information. HAPHPIPE offers a comprehensive pipeline for assembling viral consensus sequences and haplotypes, allowing for rapid analysis and quality output suitable for evolutionary studies.

Summary: Many interspecific interactions are influenced by coevolution, but the role of coevolution in the maintenance of horizontally transmitted symbioses is unclear. This study tested for evidence of pairwise coevolution in an insect-bacteria symbiosis and found no evidence of reciprocal specialization between hosts and symbionts. The results suggest that generalist dynamics and diffuse coevolution may be more important in this interaction.

Summary: HIV-2 infection progresses at a slower rate compared to HIV-1, and this study found that lower viral loads, enhanced T-cell responses, and positive selection on conserved residues are associated with slower progression. Faster progressors had higher viral diversity and evolutionary rates. The study also identified specific amino acid differences in the p26 protein associated with progression. This research suggests that HIV-2 p26 may be a potential therapeutic target.

Summary: The abundance and amino acid composition of a protein called Spiralin B (SpiB) plays a crucial role in the nutritional interactions between insects and their endosymbionts. Increasing SpiB levels disrupts the localization of endosymbionts in insect eggs and decreases vertical transmission. This protein ensures the durability of the interaction in a variable environment.

Summary: Cleaning symbiosis is crucial for maintaining healthy biological communities in tropical marine ecosystems, but it may also facilitate the transmission of parasites. Experimental evidence shows that the bluestreak cleaner wrasse, L. dimidiatus, is susceptible to some parasites but exhibits resistance and can temporarily transport parasites.

Summary: The study found a 25% rate of persistence of Staphylococcus aureus in patients with diabetic foot infections (DFI), with most cases having a relatively short persistence time. During persistent colonization, changes in bacterial genome content were observed, highlighting the low adaptive ability of S. aureus to the specific environment and stressful conditions of diabetic foot ulcers.

Summary: Symbioses play a significant role in biological influence, with particular relevance for disease, evolutionary transitions, and ecological communities. The extent to which symbiont phylogenies mirror those of their hosts reveals insights into evolutionary processes. Vertical transmission and mutualism are key factors promoting closer ties between hosts and symbionts, with symbiont phylogeny broadly reflecting host phylogeny across biodiversity and life history.

Summary: The prevalence of specific microbes in a host population can increase even when they do not provide specific benefits to the host, especially when there is overlap in their lifecycles and they share dispersal routes. This suggests that host enrichment alone is not a reliable indicator of beneficial host-microbe interactions, but increased time spent associated with a host can lead to new selection conditions, potentially favoring microbial adaptations towards a host-associated lifestyle and laying the foundation for the evolution of mutually beneficial coevolved symbioses.

Summary: Wolbachia, an endosymbiotic bacteria, infects diverse arthropods and nematode hosts and has various interactions. The taxonomy of Wolbachia is defined by supergroups, while its evolutionary history involves horizontal transfers and secondary losses. In this study, the diversity of Wolbachia infecting springtails was characterized, and new genotypes were identified. The phylogeny of Wolbachia was rooted using a different group infecting plant-parasitic nematodes. It is hypothesized that the ancestor of Wolbachia was consumed by soil-dwelling nematodes and was then transferred to aphids and subsequently infected edaphic arthropods before expanding to other terrestrial arthropods and filarial nematodes.

Summary: Genome sequences of Symbiodiniaceae are still scarce due to their large genome sizes and unique genome features. This study presented de novo genome assemblies of seven members of the genus Symbiodinium, revealing high sequence and structural divergence among different lineages, with some Symbiodinium isolates showing comparable divergence to distinct genera of Symbiodiniaceae.

Summary: This research introduces a technique that makes Illumina short-read libraries compatible with the ONT MinION sequencer by using the rolling circle amplification method. By amplifying short DNA molecules into longer ones, the resulting DNA is better suited for ONT MinION sequencing, and high-accuracy consensus reads similar to Illumina MiSeq can be obtained.
