Summary: A novel actinomycete strain, Streptomyces telluris AA8(T), was isolated from the rhizosphere soil of Mangifera indica in Bangkok, Thailand. The strain showed similarities to Streptomyces roseifaciens MBT76(T) based on the 16S rRNA gene tree, but genome-based analysis revealed differences in nucleotide and amino acid identities. Physiological and biochemical properties further distinguished strain AA8(T) from other Streptomyces species. Additionally, compound 7 (3,4-dihydroxybenzaldehyde) isolated from the strain exhibited potent antioxidant activity comparable to ascorbic acid.

Summary: A novel strain of Gram-stain-positive actinobacterium, named Streptomyces beihaiensis sp. nov., was isolated from shrimp pond soil in Tieshangang Saltern, Beihai, PR China. The strain displayed distinct morphological, chemotaxonomic, and phylogenetic characteristics, indicating its classification in the genus Streptomyces. Genomic analysis suggested that strain GXMU- J5(T) has the ability to degrade chitin. The type strain is GXMU- J5(T) (=MCCC 1K08064(T)=JCM 35629(T)).

Summary: In this study, a novel actinobacterium called strain SMC 277(T) was isolated from clay soil in a paddy field in Thailand. The strain was characterized using various taxonomic methods and was identified as a member of the genus Streptomyces. Genome sequencing revealed the presence of 35 biosynthetic gene clusters encoding diverse bioactive secondary metabolites, and the strain showed antimicrobial activity against drug-resistant bacteria associated with nosocomial infections. Based on these findings, the strain was proposed as a new species called Streptomyces antimicrobicus.

Summary: A novel actinobacterium, named HIs16- 36(T), was isolated from the rhizosphere of a mangrove on Ishigaki Island, Okinawa, Japan. Phylogenetic analysis revealed that HIs16- 36(T) was closely related to the genus Arthrobacter. However, differences in phenotypic characteristics and genetic analysis indicate that HIs16- 36T should be distinguished as a novel species of the genus Arthrobacter, named Arthrobacter mangrovi.

Summary: In this study, a Streptomyces strain SCA2-4(T) with strong antifungal activity against Foc TR4 was isolated from the rhizospheric soil of Opuntia stricta in a dry hot valley. It was identified as a novel species named Streptomyces huiliensis, and its genome encoded multiple biosynthetic gene clusters involved in the synthesis of antimicrobial metabolites. The strain showed promise for biological control of banana Fusarium wilt by destroying cell structure of Foc TR4 and inhibiting mycelial growth and spore germination.

Summary: Extracellular vesicles (EVs) are membrane-derived lipid bilayers released by cells. Bacterial EVs (BEVs) have attracted interest as potential diagnostic markers due to their differential bacterial composition in biofluids between patients and healthy controls. This review outlines the commonly used approach for investigating BEVs in biofluids, including 16S ribosomal RNA gene sequencing, and discusses the potential of BEVs as biomarkers for various diseases.

Summary: Pteropine orthoreovirus (PRV), a bat-borne virus, is associated with acute respiratory infections (ARI) in humans. Among 632 urban outpatients, 2.2% tested positive for PRV. Symptoms included cough, sore throat, and muscle ache, with minimal fever. Genetic analysis revealed the continuous evolution of PRV through reassortment among human, bat, and non-human primate hosts, emphasizing the importance of monitoring its prevalence and diversity.

Summary: This study investigates the heterozygosity and population size dynamics of migratory insects using genomic data. The findings show that migratory species have higher levels of genome-wide heterozygosity than nonmigratory species. The study also reveals that migratory Lepidoptera maintain overall genetic diversity and demographic stability despite the risks associated with migration and local environmental fluctuations.

Summary: This study examined the antibacterial effects of Mentha longifolia essential oil and pulegone in edible coatings on the growth of Staphylococcus aureus, Listeria monocytogenes, and Escherichia coli in cheese. The results showed that the addition of these compounds significantly reduced bacterial growth during storage. Increasing the concentration of chitosan, M. longifolia, and pulegone in the coatings further decreased the bacterial population, with pulegone exhibiting a stronger effect. Overall, the findings suggest that M. longifolia essential oil and pulegone, combined with alginate and chitosan coatings, have antibacterial effects against S. aureus, L. monocytogenes, and E. coli in cheese.

Summary: Probiotics have the potential to improve human health and are a lucrative industry. They may be a customizable treatment for depression, offering a precision psychiatry-based approach. The use of probiotics for depression is supported by the microbiota-gut-brain axis mechanisms. Lactobacillus and Bifidobacterium strains are the most widely studied and commercially available probiotics for major depressive disorder (MDD).

Summary: This study aimed to identify and review research related to the practice of patients with DM in Brunei Darussalam in order to identify associated factors influencing diabetic medication knowledge and adherence. The results revealed relatively poor medication knowledge and inappropriate diabetes-related practices in studies conducted in Brunei Darussalam. However, no study has directly measured both medication awareness and compliance among Brunei Darussalam T2DM patients. Future studies can focus on the relation between these two factors in different geographical locations characterized by different diabetes-related practices and culture.

Summary: A new probiotic, Christensenella minuta, was discovered in 2012 from healthy human stool. It is a subdominant commensal bacterium with highly heritable properties and has mutual interactions with other heritable microbiomes. Its relative abundance is positively correlated with the lean host phenotype. Various studies have shown its potential in managing metabolic diseases such as obesity, inflammatory bowel disease, and type 2 diabetes.
