    Treating microbial infections, especially those exhibiting antibiotic resistance, phage therapy emerges as a viable alternative compared to conventional antibiotics. A significant hurdle in the development of phage-based therapies is pinpointing the ideal phage for tackling bacterial infections. This research sought to accurately predict phage-host interactions, leading to the identification of potential bacteriophages for combating bacterial infections. Employing a training dataset of 826 phage-host interactions, the models were developed, subsequently assessed using a validation dataset encompassing 1201 phage-host interactions. Alignment-based models, using phage-phage (BLASTPhage), host-host (BLASTHost), and phage-CRISPR (CRISPRPred) comparisons, demonstrated accuracy scores fluctuating between 424% and 662% for BLASTPhage, 55% and 784% for BLASTHost, and 437% and 802% for CRISPRPred, respectively, across five taxonomic levels. Following that, alignment-free models were produced employing machine learning methodologies. Hybrid models, integrating alignment-free models and similarity scores, demonstrated a maximum performance range of 606-935% in the third instance. In conclusion, an ensemble model has been constructed, incorporating the hybrid and alignment-based models. At the Genus, Family, Order, Class, and Phylum levels on the validation dataset, our ensemble model attained a top accuracy of 679%, 806%, 855%, 90%, and 935%, respectively. To support the scientific community, we’ve developed PhageTB, a web server, and have made a separate software package available (https//webs.iiitd.edu.in/raghava/phagetb/).

    The evaluation of biological degradation in waterlogged archaeological wood is imperative to choosing the right, conservative, and protective treatments for the wood. The organic wooden material is decomposed only by adapted microbes, such as erosion bacteria and soft-rot fungi, in the waterlogged environment, which is characterized by a lack of oxygen. The microbial communities and biodegradation state of wooden fragments housed within storage tanks were investigated and assessed. raf signaling The artifacts of the Neolithic village, La Marmotta, found beneath the waters of Bracciano Lake in Lazio, Italy, were preserved due to waterlogging.

    An optical microscope was employed to initially identify the waterlogged wood samples taxonomically, enabling concurrent evaluation of their preservation condition. The Oxford Nanopore Technologies (ONT) MinION platform enabled the sequencing of Internal Transcribed Spacer (ITS) fungal sequences and 16S bacterial sequences, allowing for an evaluation of the microbial community.

    Sequencing of the identified microbial community reveals a profile consistent with waterlogged samples, with a noticeable presence of bacteria implicated in wood decomposition and lignin-degrading fungi.

    Using ONT, the first application of targeted metabarcoding, as demonstrated in the reported results, focused on the biodeterioration of waterlogged archaeological wood.

    The reported findings detail the first instance of ONT-mediated targeted metabarcoding being employed to study the biodeterioration of waterlogged archaeological wooden artifacts.

    LAMP primer design software facilitated the creation of primers specific to conserved sequences.

    Regarding the ureB gene. LAMP amplification leveraged UreB-FIP-labeled biotin. FAM-labeled probes were then hybridized to the resultant LAMP amplification products for detection, using a lateral flow device (LFD). Besides this, a clinical study was designed to analyze the performance of LAMP-LFD using 20 fecal samples.

    The optimized parameters demonstrated that

    LFD detection methods allowed for the isolation of this particular substance without cross-reacting with other components.

    Bacteria were identified through the LAMP technique, which involved a 60-minute incubation at 65°C. A detection method’s minimum threshold was established at 10.

    A measurement of copies per liter, displaying a sensitivity that was 100 times superior to polymerase chain reaction (PCR).

    Bovine ephemeral fever virus (BEFV) is categorized under the genus

    Situated under the family’s purview,

    Bovine ephemeral fever (BEF) in cattle and water buffalo is primarily caused by .

    The complete genome sequence of BEFV/CQ1/2022, an isolate from recent BEF outbreaks in Southwest China, is presented in this research.

    Comparative genomic analyses of BEFV/CQ1/2022 versus GenBank isolates exhibited substantial inter-isolate variation. Concerning the isolates’ evolutionary relationships and geographic distribution, the sequence divergence was a significant factor. Phylogenetic analysis demonstrates the division of global BEFV isolates into four distinct lineages. The East Asian lineage possessed the highest level of diversity and was further classified into four sublineages. Sublineage 2 encompassed BEFV/CQ1/2022 and ten other recent isolates from Mainland China, a notable discovery. In Southwest China, a novel sublineage of the East Asian BEFV was identified, and this study examined the substantial divergence and potential recombination among various BEFV strains, potentially advancing our understanding of BEFV epidemiology and evolution.

    A study of BEFV/CQ1/2022’s genome in relation to other isolates available in GenBank revealed remarkable disparities between the isolates. The evolutionary relationships and the isolates’ geographical distribution were reflected in the sequence divergence. The global BEFV isolates, according to phylogenetic analysis, fall into four discernible lineages. The East Asian lineage, featuring the greatest variety, could be sorted into four distinct sub-lineage groups. Notably, isolates from mainland China, including BEFV/CQ1/2022 and ten others, displayed a pattern of clustering within sublineage 2. This research focused on the significant divergence and potential recombination within BEFV strains, particularly within a newly discovered sublineage of East Asian BEFV in Southwest China. This study aims to enhance our comprehension of BEFV epidemiology and evolutionary dynamics.

    Utilizing high-throughput sequencing, the objective of this study was to analyze microecological variations and differences in uterine and vaginal microbiomes between women experiencing early embryonic arrest and those experiencing normal pregnancies. 56 pregnant women, divided into two groups – 38 with early embryonic arrest and 18 with normal pregnancy-induced abortions – were the subjects of a systematic analysis of their vaginal and uterine microbiomes. Colonization data was ascertained by means of 16S rRNA gene amplicon sequencing. Analysis of the vaginal microbiota composition showed significant variations in the populations of Lactobacillus, Bacteroidetes, and Helicobacter among the diverse groups. We also determined that Lactobacillus iners, Lactobacillus crispatus, Lactobacillus gasseri, and Lactobacillus jensenii were the most abundant Lactobacillus species, and that L. iners demonstrated a noteworthy difference in prevalence amongst the different cohorts. The receiver operating characteristic (ROC) curve analysis highlighted Ensifer as having the most significant predictive value for the occurrence of early embryonic arrest. The uterine cavity’s microbial community was characterized by the dominance of Proteobacteria, Bacteroidetes, Firmicutes, and Actinobacteria at the phylum level, and the prevalence of Bacteroides, Pseudarthrobacter, Lactobacillus, and Ralstonia at the genus level. Further study into Lactobacillus taxonomy indicated L. iners, L. crispatus, L. gasseri, and L. jensenii as the predominant species. A notable disparity existed in L. jensenii prevalence between the typical pregnancy cohort and the early embryonic arrest cohort. Using random forest methodology, 18 different genera were found within the uterine microenvironment. ROC curve analysis subsequently determined that Candidatus Symbiobacter, Odoribacter, Blautia, Nocardioides, and Ileibacterium had a demonstrable predictive capacity.

    Enterobacterales, a group of Gram-negative bacteria, frequently exhibit extended antimicrobial resistance (AMR), thereby acting as a conduit for the transmission of resistance genes to other bacterial species found in the same environment. Considering the impact on human health and the dearth of new antibiotics, the World Health Organization (WHO) designated carbapenem-resistant and ESBL-producing bacteria as critical. The environment’s influence on Enterobacterales-mediated antimicrobial resistance (AMR) transmission, in both human and animal health, warrants investigation under the One Health approach, specifically to understand the role of AMR organisms and antimicrobial resistance genes (ARGs). Antibiotic-resistant bacteria present in animal manure contribute significantly to the environment, enabling the accumulation of resistant genes.
