Cellular and physiological effects of anthrax exotoxin and its relevance to disease

open access: yesFrontiers in Cellular and Infection Microbiology, 2012
Bacillus anthracis, the causative agent of anthrax, secretes a tripartite exotoxin that exerts pleiotropic effects on the host. The purification of the exotoxin components, protective antigen, lethal factor, and edema factor allowed the rapid ...

Characterization and expression analysis of Staphylococcus aureus pathogenicity island 3 - Implications for the evolution of staphylococcal pathogenicity islands [PDF]

open access: yes, 2002
We describe the complete sequence of the 15.9-kb staphylococcal pathogenicity island 3 encoding staphylococcal enterotoxin serotypes B, K, and Q. The island, which meets the generally accepted definition of pathogenicity islands, contains 24 open reading

Localized Periodontitis in Young Individuals: Aggregatibacter JP2 Clone, Immunological Dysfunctions and Other Stories

open access: yesJournal of Periodontal Research, EarlyView.
This review describes the features of grade C molar‐incisor pattern periodontitis and discusses the role of A. actinomycetemcomitans in its pathogenesis and why molars and incisors are preferably affected. Possible future studies on this aggressive disease in primary and permanent dentition and emerging omics techniques for diagnosis and management are

Structure of a translocation signal domain mediating conjugative transfer by Type IV secretion systems [PDF]

open access: yes, 2013
Relaxases are proteins responsible for the transfer of plasmid and chromosomal DNA from one bacterium to another during conjugation. They covalently react with a specific phosphodiester bond within DNA origin of transfer sequences, forming a nucleo ...

Active immunization using exotoxin A confers protection against Pseudomonas aeruginosa infection in a mouse burn model

open access: yesBMC Microbiology, 2009
Background Pseudomonas aeruginosa is an important cause of nosocomial infection and may lead to septicemia and death. We evaluated the immunogenicity of semi-purified exotoxin A from the bacterium in a mouse burn model.

Detection of Fungal Translocation in Patients With Alcohol Use Disorder Using a Real‐Time PCR Assay

open access: yesAPMIS, Volume 134, Issue 3, March 2026.
ABSTRACT Gut microbiota plays a key role in triggering various diseases. However, translocation studies focus on bacteria, neglecting fungal elements, while fungi seem also involved in triggering various diseases. Aim of this study was to assess whether fungal elements were able to translocate in patients with AUD (alcohol use disorder) and to verify ...
