Characterizing RecA-Independent Induction of Shiga toxin2-encoding Phages by EDTA Treatment [PDF]

open access: yes, 2013
The bacteriophage life cycle has an important role in Shiga toxin (Stx) expression. The induction of Shiga toxin-encoding phages (Stx phages) increases toxin production as a result of replication of the phage genome, and phage lysis of the host cell also

A novel type I toxin-antitoxin system modulates persister cell formation in Staphylococcus aureus

open access: yesInternational Journal of Medical Microbiology, 2020
A plethora of toxin-antitoxin systems exist in bacteria and has multilateral roles in bacterial pathogenesis and virulence. Toxin-antitoxin systems have been involved in persister cell formation in Escherichia coli and Mycobacterium but have not been ...

The teneurin C-terminal domain possesses nuclease activity and is apoptogenic. [PDF]

open access: yes, 2018
Teneurins are type 2 transmembrane proteins expressed by developing neurons during periods of synaptogenesis and apoptosis. Neurons expressing teneurin-1 synapse with other teneurin-1-expressing neurons, and neurons expressing teneurin-2 synapse with ...

Bacillus anthracis edema factor substrate specificity: evidence for new modes of action [PDF]

open access: yes, 2012
Since the isolation of Bacillus anthracis exotoxins in the 1960s, the detrimental activity of edema factor (EF) was considered as adenylyl cyclase activity only.

Mechanism of Gene Regulation by a Staphylococcus aureus Toxin

open access: yesmBio, 2016
The virulence of many bacterial pathogens, including the important human pathogen Staphylococcus aureus, depends on the secretion of frequently large amounts of toxins. Toxin production involves the need for the bacteria to make physiological adjustments

"Alternative" endocytic mechanisms exploited by pathogens: new avenues for therapeutic delivery? [PDF]

open access: yes, 2007
Some pathogens utilize unique routes to enter cells that may evade the intracellular barriers encountered by the typical clathrin-mediated endocytic pathway.

A large scale prediction of bacteriocin gene blocks suggests a wide functional spectrum for bacteriocins

open access: yes, 2015
Bacteriocins are peptide-derived molecules produced by bacteria, whose recently-discovered functions include virulence factors and signalling molecules as well as their better known roles as antibiotics.

The effect of Staphylococcus aureus carriage in late pregnancy on antibody levels to staphylococcal toxins in cord blood and breast milk. [PDF]

open access: yes, 2008
We investigated the effect of carriage of Staphylococcus aureus in the later stages of pregnancy on levels of antibody specific to the S. aureus toxins, staphylococcal enterotoxin B (SEB), staphylococcal enterotoxin C (SEC) and toxic shock syndrome toxin-

Bacterial Toxins: Friends or Foes?

open access: yesEmerging Infectious Diseases, 1999
Many emerging and reemerging bacterial pathogens synthesize toxins that serve as primary virulence factors. We highlight seven bacterial toxins produced by well-established or newly emergent pathogenic microbes.
