The stress of carrying CRISPR-Cas. [PDF]

Virulence
Abstract Streptococcus anginosus ( S. anginosus ) is a commensal that can cause severe invasive bacterial infections. A considerable percentage of S. anginosus strains harbor CRISPR-Cas systems, which apart from being a bacterial

Evolution and classification of the CRISPR–Cas systems [PDF]

Nature Reviews Microbiology, 2011
The CRISPR-Cas (clustered regularly interspaced short palindromic repeats-CRISPR-associated proteins) modules are adaptive immunity systems that are present in many archaea and bacteria. These defence systems are encoded by operons that have an extraordinarily diverse architecture and a high rate of evolution for both the cas genes and the unique ...

Functional Coupling and Evolutionary Relationships Between Toxin–Antitoxin Systems and CRISPR-Cas Systems [PDF]

Toxins
Bacteria encode a broad range of survival and defence systems, including CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats)-Cas systems, restriction-modification systems, and toxin–antitoxin (TA) systems, which are involved in bacterial ...

CRISPR-Cas is beneficial in plasmid competition, but limited by competitor toxin-antitoxin activity when horizontally transferred. [PDF]

PLoS Biology
Bacteria can encode dozens of different immune systems that protect them from infection by mobile genetic elements (MGEs). MGEs themselves may also carry immune systems, such as CRISPR-Cas, to target competitor MGEs. It is unclear when this is favored by

CASPredict: a web service for identifying Cas proteins [PDF]

PeerJ, 2021
Clustered regularly interspaced short palindromic repeats (CRISPR) and their associated (Cas) proteins constitute the CRISPR-Cas systems, which play a key role in prokaryote adaptive immune system against invasive foreign elements.

Phylogenetic Distribution of CRISPR-Cas Systems in Staphylococcus lugdunensis

Microbiology Spectrum, 2021
Clustered regularly interspaced short palindromic repeats (CRISPRs) and CRISPR-associated (Cas) genes (CRISPR-Cas) are present in many bacterial genomes with functions beyond adaptive immunity.

An Endogenous Staphylococcus aureus CRISPR-Cas System Limits Phage Proliferation and Is Efficiently Excised from the Genome as Part of the SCCmec Cassette

Microbiology Spectrum, 2023
CRISPR-Cas is an adaptive immune system that allows bacteria to inactivate mobile genetic elements. Approximately 50% of bacteria harbor CRISPR-Cas; however, in the human pathogen Staphylococcus aureus, CRISPR-Cas loci are less common and often studied ...

CRISPR-Cas-Integrated LAMP

Biosensors, 2022
Pathogen-specific point-of-care (PoC) diagnostic tests have become an important need in the fight against infectious diseases and epidemics in recent years. PoC diagnostic tests are designed with the following parameters in mind: rapidity, accuracy, sensitivity, specificity, and ease of use.

Comparison of CRISPR–Cas Immune Systems in Healthcare-Related Pathogens

Frontiers in Microbiology, 2021
The ESKAPE pathogens (Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacter species) and Clostridium difficile have been identified as the leading global cause of multidrug ...

CRISPR-Cas-Docker: web-based in silico docking and machine learning-based classification of crRNAs with Cas proteins

BMC Bioinformatics, 2023
Background CRISPR-Cas-Docker is a web server for in silico docking experiments with CRISPR RNAs (crRNAs) and Cas proteins. This web server aims at providing experimentalists with the optimal crRNA-Cas pair predicted computationally when prokaryotic ...
