Prophage excision and replication.

, 2013
Agarose gel analysis of prophage excision and circularization products corresponding to attB and attP regions, respectively, probed by PCR. (A) Experimental approach: two sets of primers were used to detect prophage excision from the chromosome.

Prophage-DB: a comprehensive database to explore diversity, distribution, and ecology of prophages

Environmental Microbiome
Abstract Background Viruses that infect prokaryotes (phages) constitute the most abundant group of biological agents, playing pivotal roles in microbial systems. They are known to impact microbial community dynamics, microbial ecology, and evolution.

First Report of blaCTX‐M‐15 in a Marine Thermotolerant Enterobacter Isolate From Bangladesh: Genomic Insights Into Halotolerance and Antimicrobial Resistance

MicrobiologyOpen, Volume 15, Issue 5, October 2026.
Marine‐derived Enterobacter kobei, exhibiting thermotolerance and salt tolerance, is ESBL‐producing and harbors AMR genes (blaCTX‐M‐15, qnrS1) and mobile genetic elements, indicating environmental spread of antimicrobial resistance. ABSTRACT Marine ecosystems are becoming important reservoirs for antimicrobial resistance (AMR). However, genomic data on

Genomic and Phenotypic Classification of Staphylococcus Species Isolated From Delhi Air

Environmental Microbiology Reports, Volume 18, Issue 5, October 2026.
Multiple Staphylococcus spp. were isolated from the outdoor polluted air of the Indian Capital, New Delhi. The bacterial samples were collected from 6 different locations, and the whole genome of four Staphylococcus isolates was sequenced in their entirety. This study presents the comparative genomic analysis of these four isolates.

Prophages and satellite prophages are widespread in Streptococcus and may play a role in pneumococcal pathogenesis [PDF]

Nature Communications, 2019
Abstract Prophages (viral genomes integrated within a host bacterial genome) can confer various phenotypic traits to their hosts, such as enhanced pathogenicity. Here we analyse >1300 genomes of 70 different Streptococcus species and identify nearly 800 prophages and ...

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, Volume 600, Issue 17, Page 2564-2578, September 2026.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Frequent Sweetened Beverage Consumption Is Associated With Accelerated Biological Aging: Evidence From a Population‐Based Study and Gut Microbiota Analysis

Advanced Science, Volume 13, Issue 54, 28 September 2026.
Frequent sweetened beverage consumption is associated with accelerated biological aging in a large Chinese population. Five gut microbial genera are consistently enriched in both frequent sweetened beverage consumers and individuals with accelerated aging and show significant mediating effects, suggesting a potential microbiota‐related pathway linking ...

Prophage WO encodes a putative lytic cassette.

, 2022
Adjacent to the tail module of most prophage WO variants are three phage lysis candidates: ankyrin repeat containing protein (not shown), holin-like, and patatin-like phospholipase.

Prophage induction is enhanced and required for renal disease and lethality in an EHEC mouse model.

PLoS Pathogens, 2013
Enterohemorrhagic Escherichia coli (EHEC), particularly serotype O157:H7, causes hemorrhagic colitis, hemolytic uremic syndrome, and even death. In vitro studies showed that Shiga toxin 2 (Stx2), the primary virulence factor expressed by EDL933 (an O157 ...

Active Lysogeny in Listeria Monocytogenes Is a Bacteria-Phage Adaptive Response in the Mammalian Environment

Cell Reports, 2020
Summary: Some Listeria monocytogenes (Lm) strains harbor a prophage within the comK gene, which renders it inactive. During Lm infection of macrophage cells, the prophage turns into a molecular switch, promoting comK gene expression and therefore Lm ...
