A Robust One-Step Recombineering System for Enterohemorrhagic Escherichia coli [PDF]

Microorganisms, 2022
Enterohemorrhagic Escherichia coli (EHEC) can cause severe diarrheic in humans. To improve therapy options, a better understanding of EHEC pathogenicity is essential. The genetic manipulation of EHEC with classical one-step methods, such as the transient

Effects of common Gram-negative pathogens causing male genitourinary-tract infections on human sperm functions [PDF]

Scientific Reports, 2021
Male genitourinary tract (MGT) bacterial infections are considered responsible for 15% of male infertility, but the mechanisms underlying decreased semen quality are poorly known. We evaluated in vitro the effect of strains of Gram-negative uropathogenic

CRISPR-based genome editing reveals the roles of efflux pumps in <i>Mycobacterium abscessus</i>. [PDF]

mLife
Abstract Mycobacterium abscessus, one of the most antimicrobial‐resistant bacteria, is increasingly recognized as the cause of infections that are difficult to treat. Novel genetic manipulation tools are required to elucidate the biology, pathogenesis, and antibiotic resistance mechanisms of M. abscessus.

DdiA, an XRE family transcriptional regulator, is a co-regulator of the DNA damage response in Myxococcus xanthus [PDF]

Journal of Bacteriology
Repair of DNA damage is essential for genome integrity. DNA damage elicits a DNA damage response (DDR) that includes error-free and error-prone, i.e., mutagenic, repair. The SOS response is a widely conserved system in bacteria that regulates the DDR and

A CRISPR-nonhomologous end-joining-based strategy for rapid and efficient gene disruption in <i>Mycobacterium abscessus</i>. [PDF]

mLife
Abstract Mycobacterium abscessus, a fast‐growing, non‐tuberculous mycobacterium resistant to most antimicrobial drugs, causes a wide range of serious infections in humans, posing a significant public health challenge. The development of effective genetic manipulation tools for M.

Axiomatizing Maximal Progress and Discrete Time [PDF]

Logical Methods in Computer Science, 2021
Milner's complete proof system for observational congruence is crucially based on the possibility to equate $\tau$ divergent expressions to non-divergent ones by means of the axiom $recX. (\tau.X + E) = recX. \tau. E$.
