Summary: This study investigated the variation of bacterial communities among different host genotypes in D. galeata water fleas and examined the relationship between genetic distance and bacterial community divergence. The results indicate that host genotype may shape the bacterial community structure, but genetic distances between hosts do not correlate with diverging bacterial communities.

Summary: In this study, a novel DNA microarray system was developed that eliminates the need for labeling, amplification, or washing of target nucleic acid fragments. By using specially designed DNA probes, the system allows for quick and specific detection of DNA and RNA within a short period of time.

Summary: Microplastics (MPs) are a pervasive emerging pollutant with significant impact on the ecosystem, but certain microorganisms in the natural environment can degrade them without causing secondary pollution. This study screened microorganisms capable of degrading 11 different types of MPs as carbon sources and explored the degradation mechanism. A stable microbial community was obtained after approximately 30 days of domestication, with varying bacterial growth and degradation rates for different MPs. The degradation half-life ranged from 67 to 116 days.

Summary: Streptomyces isolates were collected from ecologically similar habitats in 13 provinces in Southern China. Based on their 16S rDNA sequences, they were classified into 96 operational taxonomic units, including eight potentially new species. The phylogenetic analysis revealed that isolates with similar geographical distributions clustered together. The beta diversity of Streptomyces showed a latitudinal diversity gradient and did not change significantly with geographic distance.

Summary: This study investigated the poorly known tick Haemaphysalis danieli in Pakistan, confirming its morphology, host record, and phylogenetic position in relation to other Haemaphysalis species. The study found a close evolutionary relationship between H. danieli and a conspecific from China, as well as an undetermined Haemaphysalis sp. from China and Anatolia.

Summary: This study investigates the effects of different terpenes on belowground bacterial and fungal microbiomes. The research finds that terpene applications have significant and variable impacts on bacterial and fungal communities, but these impacts are localized to the artificial root system and the fungal rhizosphere. The study also reveals the varying effects of terpenes on individual microbial isolates and demonstrates the complexity of microbe-terpene interactions in the rhizobiome.

Summary: This study investigates the effects of different terpenes on plant microbiomes belowground. The results show that terpene applications have significant impacts on bacterial and fungal communities, but these effects are localized to the artificial root system and fungal rhizosphere. Bioassays on responsive bacteria and fungi isolated from the sorghum rhizobiome validate the direct microbial responses to terpenes. These findings shed light on the complex interactions between terpenes and microorganisms in the rhizobiome.

Summary: This study provides a description of sediment microbial communities in the Houston Ship Channel-Galveston Bay estuary after Hurricane Harvey. The presence and abundance of specific bacterial and archaeal taxa indicate pollutant inputs and the study also observed microorganisms involved in the biodegradation of xenobiotics. The spatial occurrence of a specific degrader of persistent polychlorinated compounds is explained by sediment properties and contaminant concentrations.

Summary: To understand the browning phenomenon on stained glass windows, this study examined the microbial communities present on this material. Through 16S rDNA sequencing, cultivable bacterial communities were identified, showing different compositions depending on the sampling site. The most common genera were Arthrobacter, Micrococcus, Paenibacillus, and Bacillus, some of which are known for their weathering potential.

Summary: In this study, the relationship between gut microbiome and symptomatic unruptured intracranial aneurysms (UIA) was investigated. It was found that there were significant differences in gut microbiome composition between symptomatic and asymptomatic UIA patients, with an enrichment of Clostridiales at the order level and alterations in the family levels of Ruminococcaceae. Functional differences were also observed, including a decreased propionate metabolism pathway and an enrichment of peptidoglycan biosynthesis pathways in patients with symptomatic UIA. These findings may have implications for the management and prognosis of UIA patients.

Summary: This study found that the gut bacterial community remains relatively stable in diarrheic giraffes, but the gut fungal community shows significant changes between healthy and diarrheic states. Diarrhea causes significant alterations in gut microbial composition, with more pronounced changes observed in the gut bacterial community.

Summary: The study found that bacterial communities in compost and bamboo biochar additive differed, with compost having higher abundance of bacteria and biochar having higher diversity. Additionally, the dominant phylum Firmicutes decreased in compost samples but remained dominant in biochar additives throughout the composting period. This suggests that biochar addition can impact the bacterial composition and abundance in composting processes.

Summary: This study investigated the correlation between propionic acid production and bacterial community succession during the fermentation of gray sufu. Results showed that Propionibacterium and Lactobacillus played important roles in the production of propionic acid, while Fusobacterium, Providencia, Lactobacillus, and Bacillus were key factors in reducing propionic acid content. This research provides new insights into quality control of traditional fermented foods.

Summary: The long-standing association between insects and microorganisms plays a crucial role in the success of social insect groups. In this study, the bacterial microbiomes in soils with and without red imported fire ants were characterized, revealing significant differences in bacterial community structures. Red imported fire ants were found to have a notable impact on soil microbial communities, with differences in abundance of certain taxa and distinct bacterial compositions in worker ants compared to nest soils.

Summary: The study found that the concentration of bacterial aerosols in the broiler house varied significantly in different seasons, with the highest concentration in summer and the lowest in winter. The composition of bacterial species also varied by season, with a higher proportion of Gram-negative bacteria in autumn. Additionally, the structure of potential pathogenic bacterial genera differed by season.
