Summary: Two new bacterial strains, Marseille-P2698(T) and Marseille-P2260(T), were isolated from human stools using the culturomic method. These two strains were fully described using the taxonogenomic approach. Marseille-P2698(T) was identified as a Gram-negative, motile, non-spore-forming, rod-shaped bacterium, while Marseille-P2260(T) was identified as a Gram-positive, motile, spore-forming rod-shaped bacterium.

Summary: A Gram-negative strain, RN2-1(T), was isolated from a Korean forest soil sample. It is characterized as aerobic, oxidase-positive, catalase-negative, non-motile, oval/rod-shaped, and can grow in a wide pH and temperature range. The strain belongs to a novel genus, Limobrevibacterium gyesilva gen. nov., sp. nov., and is closely related to Rhodovastum atsumiense G2-11(T). The whole genome analysis and phenotypic data of strain RN2-1(T) support its distinctive phylogenetic position.

Summary: Strain SZY PN-1(T) is a novel Gram-negative, yellow-pigmented bacterium isolated from a skin sample of a healthy Chinese male. It shares high similarities with two invalid-published species, forming a separate branch within the family Sphingosinicellaceae based on phylogenetic analysis. A new genus and species, Sandaracinobacteroides hominis gen. nov., sp. nov., is proposed based on its phenotypic and genotypic features.

Summary: The diversity of bacteria in biopsy material from colorectal cancer patients was studied. A new bacterium, strain CC70AT, was isolated from tissue samples and identified as a Gram-positive, strictly anaerobic, motile, rod-shaped bacterium. It was able to ferment formate but not acetate. Based on DNA analysis and 16S rRNA gene sequencing, strain CC70AT belongs to the Bacillota phylum and is closely related to Cellulosilyticum lentocellum and Cellulosilyticum ruminicola. This study proposes the name Holtiella tumoricola gen. nov., sp. nov. for this novel bacterium. The type strain is CC70AT (=DSM 27931T= JCM 30568T).

Summary: Five novel halophilic archaeal strains were isolated from coastal saline sediments and sea salt in China. They demonstrated typical morphology and growth characteristics and showed high similarities with existing species. However, based on genetic and phylogenetic analyses, it is confirmed that these strains represent five new species. This is the first report of a novel haloarchaeon isolated from a marine intertidal zone.

Summary: This study investigated the bacterial community composition associated with different aquatic ecosystems in the Southwest coast of India using high-throughput 16S rRNA gene sequencing. The results revealed a higher abundance of microbes known to play a major role in the nitrogen cycle in freshwater and marine ecosystems. Functional prediction indicated microbial tolerance to organic contaminants and xenobiotics, highlighting the importance of bacterial community composition for environmental health and biotechnological applications.

Summary: Leptospirosis is a growing public health concern in the tropical and subtropical regions. The Carbo-Lip probe, developed through immuno recognition method, has shown promising results in the rapid and accurate diagnosis of Leptospirosis. Compared to other diagnostic methods, Carbo-Lip exhibited high sensitivity and specificity for detecting Leptospirosis, making it a potential early diagnostic tool for patients in endemic areas.

Summary: Urea is a major component of human urine and is mainly broken down by the urease enzyme. This study investigates the presence of an alternative enzyme system, urea carboxylase (UC) and allophanate hydrolase (AH), in a urease-negative uropathogen. The results show that this bacterium can utilize the UC and AH system for urea metabolism, and further research is proposed to explore this system in other urease-negative uropathogens and its implications for pathogenicity and urinary tract colonization.

Summary: Leptospirosis is an underestimated infectious tropical disease that is often misdiagnosed. Laboratory tests for diagnosis are crucial but time-consuming, and currently available techniques cannot detect the disease at an early stage. Therefore, there is a need for the development of rapid and affordable diagnostic methods.

Summary: Radiotherapy has an influence on the diversity and composition of the oral microbiome in patients with oral squamous cell carcinoma (OSCC). OSCC patients have a reduced species richness and altered microbial composition compared to controls. Significant shifts in the oral microbiome composition occur after six months of radiation therapy, including increased beneficial taxa and reduced pathogenic bacteria.

Summary: The study confirmed the importance of detecting sphingomyelinase in the urine of leptospirosis patients as a potential diagnostic biomarker. The unique secretion of sphingomyelinase in the urine of leptospirosis patients, compared to other febrile illnesses like dengue, malaria, and scrub typhus, provides evidence for its diagnostic value.

Summary: Hypoxic-ischemic encephalopathy (HIE) is a severe birth complication that can result in death or severe disabilities for newborns. Traditional clinical and biochemical indicators are not always accurate in assessing the severity and recovery of brain injury in HIE neonates. This study aims to identify specific proteins as biomarkers for predicting the severity of neonatal asphyxia and monitoring disease progression to reduce mortality and neurodevelopmental impairment.
