Summary: The taxonomy and soil ecology of Bacillus spp. and related bacteria require further investigation, particularly in terms of additional genetic markers and physical and chemical parameters. Additionally, research is needed to optimize the cellulolytic properties of spore-forming bacteria for more efficient industrial applications.

Summary: In this study, a Gram-positive aerobic, endospore-forming bacterium isolated from the rhizosphere of maize was taxonomically characterized as a novel species of the genus Sutcliffiella, named Sutcliffiella rhizosphaerae sp. nov., based on phylogenetic analysis and DNA-DNA hybridization. The strain showed high similarity with Sutcliffiella zhanjiangensis (98.7%) and distinct differences from other closely related species of the genus Sutcliffiella.

Summary: During the study of spoilage microbiomes in packaged broiler meat, three unknown strains were isolated and identified as two novel species of the genus Vagococcus through polyphasic taxonomy and genome-based analyses. The phenotypic characteristics and chemotaxonomic properties of these novel species were typical for vagococci. Phenotypic and genetic differences distinguished them from previously known species in the genus. The proposed names for these novel species are Vagococcus proximus sp. nov. and Vagococcus intermedius sp. nov.

Summary: This study conducted bacterial sampling and analysis on outbreaks caused by warm-water and cold-water streptococcosis, using various phenotypic and genomic testing methods, and comparing antimicrobial susceptibilities of different strains. By sequencing the genome of the VS-1 strain, 69 virulence genes and 31 antimicrobial resistance genes were identified, providing comprehensive insights into the characteristics of V. salmoninarum.

Summary: BC is a nutraceutical that can modulate intestinal microbiota. This study investigates the effects of BC diet supplementation on luminal and mucosa-associated microbiota in the jejunum, caecum, and colon of rabbits. Significant differences were found in the microbial composition of the three groups, especially in the caecum and colon of the 2.5% BC group. A functional prediction has revealed several altered pathways in BC groups, with particular reference to amino acids and lactose metabolism. Findings suggest that BC supplementation could positively affect the intestinal microbiota.

Summary: This study investigated a chronic coldwater streptococcosis epizootic in a fish hatchery in Wisconsin, USA, and developed a new quantitative real-time PCR method that can simultaneously detect concentrations of C. maltaromaticum and V. salmoninarum. The results of this study are important for differentiating and diagnosing these two emerging bacterial pathogens.

Summary: A polyphasic taxonomic approach was used to characterize two novel bacterial strains, HDW17A(T) and HDW17B(T), isolated from the intestine of diving beetles. Phylogenetic and genomic analyses showed that the isolates belonged to the genus Vagococcus, with HDW17A(T) closely related to Vagococcus fessus and HDW17B(T) closely related to Vagococcus fluvialis. The strains were proposed as new species in the genus Vagococcus, named Vagococcus coleopterorum sp. nov. and Vagococcus hydrophili sp. nov.

Summary: This study explored the relationships between gut microbiota and host's metabolism in depression using the CSDS model. The results showed that differential gut microbiota and metabolites were closely associated with depressive-like behaviors and changes in metabolism. The phylum Firmicutes, especially the genus Lactobacillus, may be involved in the onset of depression through regulating tryptophan metabolism.

Summary: This paper emphasizes the correct assignation of indicator phospholipid fatty acids (PLFA), the specificity and recycling of PLFA in microorganisms, and the complete extraction and detection of PLFA. It suggests using different PLFA indicators for different microbial groups and optimizing soil handling and PLFA analysis methods. The study also points out the importance of regular checks on gas chromatographic separation for reliability and accuracy.

Summary: The study found that penicillin has a certain impact on biofilm formation of Group B Streptococcus, reducing biofilm biomass and thickness, but not fully preventing biofilm formation. Penicillin can significantly reduce the density of live cells in biofilms, but higher concentrations do not lead to improved prevention of biofilm formation. Biofilms formed in the presence of penicillin show differences in structure compared to penicillin-free biofilms.

Summary: Burkholderia pseudomallei causes a life-threatening disease and understanding its epidemiology and antibiotic resistance mechanisms can benefit public health and safety. In this study, the authors identified genes encoding penicillin binding proteins (PBPs) in B. pseudomallei and examined their utility for determining phylogeography and differentiating closely related species. They developed a dual-locus sequence typing (DLST) scheme based on single nucleotide polymorphisms (SNPs) and demonstrated the usefulness of PBPs for strain typing and predicting geographic origin.

Summary: Group B Streptococcus (GBS) is a major pathogen in pediatric and animal diseases, with various clades that differ in virulence, antimicrobial resistance, and adaptation. Vaccination is important in reducing GBS disease burden, antimicrobial reliance, and the risk of resistance. This perspective article explores the landscape of antimicrobial resistance in GBS and discusses future perspectives in the post-pandemic era.
