A metagenomic approach was employed to investigate the diversity and distribution of Virulence Factors Genes (VFGs) and Pathogenic Bacteria (PB) in sediment samples collected from highly urbanized cities along the Indian coastline. Among the study locations, Mumbai, Veraval and Paradeep showed a higher abundance of PB, with Vibrio and Pseudomonas as dominant at the genus level, and Escherichia coli and Pseudomonas aeruginosa at the species level. In total, 295 VFGs were detected across all sediment samples, of which 40 VFGs showed a similarity of ≥90 % with the Virulence Database (VFDB) and were focused in this study. Among the virulent proteins, twitching motility protein and flagellar P-ring were found to be prevalent and significantly associated with Vibrio spp., and Pseudomonas spp., indicating potential bacterial pathogenicity. This investigation serves as the basis for future studies and provides insights into the comprehensive taxonomic profiles of PB, VFGs and their associated PB in the coastal sediments of India.

Single nucleotide variations (SNVs) and polymorphisms (SNPs) are characteristic biomarkers in various biological contexts, including pathogen drug resistances and human diseases. Tools that lower the implementation barrier of molecular SNV detection methods would provide greater leverage of the expanding SNP/SNV database. The oligonucleotide ligation assay (OLA) is a highly specific means for detection of known SNVs and is especially powerful when coupled with polymerase chain reaction (PCR).

The BioFire FilmArray® Gastrointestinal (GI) Panel, a widely used diagnostic tool, is designed to detect the genetic material of 22 common pathogens responsible for gastroenteritis, including viruses, bacteria, and parasites. It can detect human adenovirus (HAdV) species F, particularly serotypes F40 and F41, which are the major causes of diarrhea and mortality in children. However, its potential shortcomings in detecting other HAdV species limit its effectiveness in broader HAdV detection in clinical settings and outbreak investigations.

Background: Respiratory infections substantially impact pediatric health. The COVID-19 pandemic introduced widespread non-pharmaceutical interventions, which influenced the incidence of common respiratory infections. This comprehensive study investigates the impact of these interventions on the incidence of respiratory syncytial virus, influenza, and invasive pneumococcal disease in Danish children.

Bacterial blight of pomegranate caused by Xanthomonas axonopodis pv. punicae poses significant challenges to sustainable cultivation, necessitating eco-friendly management strategies, and this study explores the role of the phylloplane microbiome in disease suppression through metabarcoding, traditional microbiology, and antibacterial screening of microbial candidates. Here, we mapped the phylloplane microbiome of pomegranate cultivar 'Bhagwa' during bacterial blight development using metabarcoding sequencing (2443,834 reads), traditional microbiological methods (nutrient-rich and minimal media), and scanning electron microscopy.

Epithelial cells respond to infection with the intracellular bacterial pathogen Listeria monocytogenes by altering their mechanics to promote collective infected cell extrusion (CICE) and limit infection spread across cell monolayers. However, the underlying biochemical pathways remain elusive. Here, using in vitro (epithelial monolayers) and in vivo (zebrafish larvae) models of infection with L.
