A prophage vB_CibM-P1 was induced by mitomycin C from the epipelagic strain Citromicrobium bathyomarinum JL354, a member of the alpha-IV subcluster of marine aerobic anoxygenic phototrophic bacteria (AAPB). The induced bacteriophage vB_CibM-P1 had Myoviridae-like morphology and polyhedral heads (approximately capsid 60-100 nm) with tail fibers. The vB_CibM-P1 genome is ~38 kb in size, with 66.0% GC content. The genome contains 58 proposed open reading frames that are involved in integration, DNA packaging, morphogenesis and bacterial lysis. VB_CibM-P1 is a temperate phage that can be directly induced in hosts. In response to mitomycin C induction, virus-like particles can increase to 7 × 10(9) per ml, while host cells decrease an order of magnitude. The vB_CibM-P1 bacteriophage is the first inducible prophage from AAPB.

Lipopolysaccharide (LPS), the outermost component of Gram-negative bacterial cells, is critical to bacterial pathogenicity, functioning as an endotoxin that activates the human immune system and induces an inflammatory response during infection. LPS comprises three primary components: lipid A, the oligosaccharide core, and the O-antigen. The O-antigen, in particular, is highly variable and strain-specific, playing a pivotal role in how the host immune system recognizes bacterial cells.

Introduction: Prophages play a crucial role in the genomic diversity of , contributing to its pathogenicity and adaptation.
Methods: In this study, we induced and sequenced seven prophages from five isolates of . These were analyzed with 967 prophages identified from various isolates worldwide, plus 21 genomes of other phages infecting previously reported in NCBI.

Pseudomonas aeruginosa has increasing clinical relevance and commonly occupies the cystic fibrosis (CF) airways. Its ability to colonize and persist in diverse niches is attributed to its large accessory genome, where prophages represent a common feature and may contribute to its fitness and persistence. We focused on the CF airways niche and used 197 longitudinal isolates from 12 patients persistently infected by P.

is a common opportunistic pathogen associated with nosocomial infections. The primary treatment for infections typically involves antibiotics, which can lead to the emergence of multidrug-resistant strains. Therefore, there is a pressing need for safe and effective alternative methods.

Consuming raw or undercooked mussels can lead to gastroenteritis and septicemia due to contamination. This study analyzed the prevalence, density, species diversity, and molecular traits of spp. in 48 fresh raw wild mussels (FRMs) and 48 ready-to-eat stuffed mussels (RTE-SMs) through genome analysis, assessing health risks.
