Summary: This study provides high-resolution digital pictures and molecular data of male and female I. rugicollis for the first time, and morphological comparison with I. cornutus could not resolve uncertainties in the latter species' validity. Further molecular comparisons with new specimens of I. cornutus are needed to confirm its status. This study represents the first comprehensive molecular phylogenetic analysis of western Palearctic Pholeoixodes species, including I. rugicollis, and confirms the phylogenetic position of the subgenus Eschatocephalus within Pholeoixodes.

Summary: A study identified a Rhizobium species from a marine toxic dinoflagellate Gambierdiscus culture for the first time, suggesting a potential physiological interaction between the dinoflagellate and the bacterium as its abundance increased during the late exponential growth phase and under nitrogen limitation. Further investigation is needed to explore the prevalence and ecological roles of dinoflagellate-associated Rhizobium bacterium.

Summary: This study investigated a case of severe mortality in farmed Labeo rohita and identified the causative agent as Aeromonas veronii. The isolated strain showed resistance to ampicillin and dicloxacillin, but susceptibility to 22 other antibiotics. It was also found that A. veronii induced stress and immune responses in L. rohita. The negative effects of the pathogen on fish health and high mortality rate highlight the need for A. veronii management.

Summary: The study found that patients with thyroid carcinoma show significant changes in gut microbiota compared to healthy controls, with 70% of patients having increased levels of Proteobacteria-types. Microbiota analysis can distinguish thyroid carcinoma patients from healthy controls.

Summary: The microbiota in semen from beef bulls with satisfactory and unsatisfactory sperm quality showed differences in composition, with less co-occurrence of microbial taxa in the satisfactory group and presence of opportunistic pathogens in the unsatisfactory group. Methanobrevibacter may play a role in maintaining the microbiota in satisfactory samples, while Campylobacter and Fusobacterium may act synergistically in the unsatisfactory group.

Summary: Sequencing 16S rRNA gene amplicons is commonly used to study prokaryotic communities, but gene copy normalization (GCN) does not improve the accuracy of results. The study questions the use of GCN for metataxonomic surveys until a more comprehensive catalogue of copy numbers becomes available.

Summary: Emerging evidence suggests that the intestinal bacterial communities associated with eukaryotes, such as the Yesso scallop Patinopecten yessoensis, play critical roles in the physiological activities and health of the host. This study investigated the seasonal variation in the intestinal bacterial community and physiological indices of P. yessoensis collected from Zhangzi Island, China. The results show significant changes in the diversity and abundance of intestinal bacteria over seasons, with different dominant phyla and genera observed. The study also identified the major environmental factors and their correlation with the intestinal bacterial community. These findings contribute to our understanding of the relationship between seasonal alteration in the intestinal bacteria and the physiological status of scallops.

Summary: The availability of soil phosphorus can affect plant growth, root-soil interactions, and rhizosphere microbial community composition. This study investigated the rhizosphere microbial communities of 24 species of eucalypts under low or sufficient soil phosphorus availability. It was found that eucalypt species identity was the main factor determining the composition of the rhizosphere microbial community, while the effect of phosphorus availability varied among species.

Summary: This study characterized the microbiota of gastric cancer using 16S rRNA gene and its transcript and identified differences in bacterial composition. The results showed that there was only partial overlap between DNA and RNA samples and differences between gastric cancer patients and healthy controls depending on the chosen sequencing modality. Furthermore, RNA sequencing was more sensitive for detecting differences in bacterial richness and specific bacteria. Overall, the choice of sequencing modality affects the characterization of the microbiota and the differences between case and control.

Summary: The study aimed to increase the sensitivity of bacterial community analysis without impacting community composition or interfering with cluster formation during sequencing. The modified PCR protocol showed increased sensitivity in detecting bacterial communities in airway samples, crucial for studying the highly variable human airway microbiome.

Summary: The study investigated the composition, abundance, and environmental drivers of cyanobacterial biocrust in two important biomes in Brazil, Caatinga and Pampa, revealing distinct taxonomic compositions and assemblages at each biome. Soil temperature and pH were identified as the main factors explaining the differences in biotic structures. The findings are expected to enhance biocrust conservation efforts and promote the use of biocrust cyanobacteria as indicators of global change.

Summary: In this study, it was found that colonic host-microbial interactions are altered in patients with diarrhea-predominant irritable bowel syndrome (IBS-D) during symptom exacerbation. There were differences in the composition of fecal and oral microbiota, with no overlaps between them.

Summary: Baseline assessments of marine microbial studies around Nuclear Power Plant (NPP) sites are limited. This study focused on the distribution and diversity of marine actinobacteria and their potential remediation ability. The results showed high diversity of marine actinobacteria, with dominance of the genus Streptomyces, and the identification of a potential strain capable of producing EPS and remediating uranium radionuclides.

Summary: This study investigated a group of cyanobacterial strains resembling Leptolyngbya morphotypes using a polyphasic approach, leading to the discovery of a new genus named Monilinema. The unique characteristics of these strains, including their morphology, genetic divergence, and ecological features, support the establishment of this novel taxon within the cyanobacterial diversity.
