Mathematical modelling of CRISPR-Cas system effects on biofilm formation

Journal of Biological Dynamics, 2017
Clustered regularly interspaced short palindromic repeats (CRISPR), linked with CRISPR associated (Cas) genes, can confer adaptive immunity to bacteria, against bacteriophage infections.

Prophages in Lactobacillus reuteri Are Associated with Fitness Trade-Offs but Can Increase Competitiveness in the Gut Ecosystem

Applied and Environmental Microbiology, 2019
Bacteriophages derived from lysogens are abundant in gut microbiomes. Currently, mechanistic knowledge is lacking on the ecological ramifications of prophage carriage yet is essential to explain the abundance of lysogens in the gut.

Lysogeny destabilizes computationally simulated microbiomes

Ecology Letters, Volume 27, Issue 6, June 2024.
Predation by phages shapes bacterial communities in microbiomes, but no theory exists to predict how lysogeny affects bacterial community composition and dynamics. We used computational models to show that lysogenic phages can destabilize bacterial communities, with potential impacts on the health of microbiome hosts.

The etherase system of Novosphingobium sp. MBES04 functions as a sensor of lignin fragments through phenylpropanone production to induce specific transcriptional responses

Environmental Microbiology Reports, Volume 16, Issue 1, February 2024.
Novosphingobium sp. MBES04 possesses a unique ability to sense lignin fragments by producing phenylpropanones which induce specific transcriptional responses. The strongly induced clusters involved in energy production by oxidative degradation and multidrug resistance. This adaptation may be a survival strategy, whereby the strain MBES04 preferentially

Discovery of natural bispecific antibodies: Is psoriasis induced by a toxigenic Corynebacterium simulans and maintained by CIDAMPs as autoantigens?

Experimental Dermatology, Volume 33, Issue 1, January 2024.
Abstract The high abundance of Corynebacterium simulans in psoriasis skin suggests a contribution to the psoriasis aetiology. This hypothesis was tested in an exploratory study, where western blot (WB) analyses with extracts of heat‐treated C. simulans and psoriasis serum‐derived IgG exhibited a single 16 kDa‐WB‐band.

Population fitness and the regulation of Escherichia coli genes by bacterial viruses.

PLoS Biology, 2005
Temperate bacteriophage parasitize their host by integrating into the host genome where they provide additional genetic information that confers higher fitness on the host bacterium by protecting it against invasion by other bacteriophage, by increasing ...

Mycobacterium Phage Butters-Encoded Proteins Contribute to Host Defense against Viral Attack

mSystems, 2020
A diverse set of prophage-mediated mechanisms protecting bacterial hosts from infection has been recently uncovered within cluster N mycobacteriophages isolated on the host, Mycobacterium smegmatis mc2155.

Isolation of a human epidermal cDNA corresponding to the 180-kD autoantigen recognized by bullous pemphigoid and herpes gestationis sera. Immunolocalization of this protein to the hemidesmosome.

Journal of Clinical Investigation, 1990
Autoantibodies present in the sera of patients with bullous pemphigoid (BP) bind to the basement membrane zone of normal human skin and commonly recognize two epidermal proteins, the BP240 and BP180 antigens. Two BP antigen cDNA clones from a lambda gt11
