Summary: Phytophagous stink bugs carry nutritional symbiotic bacteria in their midgut to balance their diet, with most symbionts in the Pentatomidae affiliated to the genus Pantoea. A novel Pantoea species ('Candidatus Pantoea persica') was discovered in the gut of the pentatomid Acrosternum arabicum, which is important for host development. Comparative analyses showed a convergent pattern of genome reduction in symbionts of pentatomids, following typical models of obligate nutritional symbionts in insects.

Summary: A newly discovered Rickettsiales bacterium associated with the ciliate Paramecium has a genome encoding lineage-specific features, particularly the mevalonate pathway gene repertoire. Additionally, phylogenetically unrelated mevalonate pathway genes were found in Rickettsiales sequences, suggesting evolutionary convergent effects of independent horizontal gene transfer events. This highlights convergence as an important evolutionary phenomenon in Rickettsiales, potentially contributing to hidden origins of nuanced similarities among sub-lineages.

Summary: The first detection of a male Amblyomma variegatum tick infesting a sheep on the island of Sardinia and the presence of Rickettsia africae in DNA extracted from this tick are reported. The authors suggest that the tick's presence is likely due to migrating birds from Africa. This incidental finding highlights the potential risk of establishment of these ticks in the region and the importance of continued monitoring for public health.

Summary: Recent studies in various areas of Africa have emphasized the significant impact of ticks on animal and human health. Limited information was found on the bacterial endosymbionts of African ticks and their co-infections with pathogens, despite their crucial role in tick survival and transmission efficiency. The research investigated the distribution of selected pathogens and symbiotic bacteria in hard ticks collected from different ecological zones in Africa, identifying species like Amblyomma, Dermacentor, Hyalomma, Haemaphysalis, Ixodes, and Rhipicephalus. Molecular screening revealed the presence of various pathogens, such as spotted fever group rickettsiae and Babesia spp., while Coxiella was the most prevalent symbiont among different tick species.

Summary: This study characterized a novel Holosporales symbiont that inhabits a ciliate host, showing potential lethal effects on host cell division and a heavy dependence on the host. The bacterium's features suggest a mildly parasitic effect on the host, with a trend towards genome reduction and fast evolution. Similar convergent features with other host-associated lineages, such as Rickettsiales among Alphaproteobacteria, were observed.

Summary: Plant proteins, such as those from soy, contain bioactive peptides and proteins with antioxidant, ACE-inhibitory, anti-hypertensive, and antimicrobial activities. In this study, peptides and proteins produced during in vitro gastrointestinal digestion of soy protein isolate were found to have significant growth inhibitory effects on E. coli, supporting their potential antimicrobial properties. These findings suggest that soy-based supplements may have beneficial effects after human consumption and could potentially be recycled for animal nutrition in line with the circular economy concept.
