Lipidation of the FPI protein IglE contributes to Francisella tularensis ssp. novicida intramacrophage replication and virulence
Abstract Francisella tularensis is a Gram‐negative bacterium responsible for the human disease tularemia. The Francisella pathogenicity island (FPI) encodes a secretion system related to type VI secretion systems (T6SS) which allows F. tularensis to escape the phagosome and replicate within the cytosol of infected macrophages and ultimately cause disease. A lipoprotein is typically found encoded within T6SS gene clusters and is believed to anchor portions of the secretion apparatus to the outer membrane. We show that the FPI protein IglE is a lipoprotein that incorporates 3H‐palmitate and localizes to the outer membra...

Involvement of toxin–antitoxin modules in Burkholderia cenocepacia biofilm persistence
In this study, we investigated whether TA modules contribute to persistence toward antibiotics in Burkholderia cenocepacia J2315. Sixteen pairs of genes were identified based on their apparent similarity to TA modules. Overexpression of the putative toxins had various effects on growth, persistence, and biofilm formation. Toxins, whose overexpression resulted in growth inhibition, often increased the number of surviving persisters; in contrast, overexpression of putative toxins showing no effects on growth had no positive influence on the number of surviving persisters. Furthermore, the expression of the TA modules was com...

Growth, motility and resistance to oxidative stress of the melioidosis pathogen Burkholderia pseudomallei is enhanced by epinephrine
This study provides the first evidence that epinephrine, a hormone released from the host under stress and upon therapy, can affect B. pseudomallei virulence‐associated properties. This article is protected by copyright. All rights reserved. (Source: FEMS Immunology and Medical Microbiology)

Systems kinomics for characterizing host responses to high‐consequence pathogens at the NIH/NIAID Integrated Research Facility‐Frederick
Abstract Currently, there is a paucity of information regarding the molecular pathogenesis for many high‐consequence pathogens (HCPs) that pose threats to both national and international public health. In spite of this, investigations of the molecular pathogenesis for many HCPs have been limited to gross pathological changes in animal models or global analysis of gene expression. Further, questions remain regarding the ability of animal models of disease to recapitulate human molecular pathogenesis or act as predictors of therapeutic efficacy. Thus, it is likely that medical countermeasure development for HCPs will rely ...

The emergence of the Middle East Respiratory Syndrome coronavirus
Abstract On September 20, 2012, a Saudi Arabian physician reported the isolation of a novel coronavirus from a patient with pneumonia on ProMED‐mail. Within a few days, the same virus was detected in a Qatari patient receiving intensive care in a London hospital, a situation reminiscent of the role air travel played in the spread of severe acute respiratory syndrome coronavirus (SARS‐CoV) in 2002. SARS‐CoV originated in China's Guangdong Province and affected more than 8000 patients in 26 countries before it was contained 6 months later. Over a year after the emergence of this novel coronavirus – Middle East respi...

LEAP‐2, LL‐37 and RNase7 in tonsillar tissue: downregulated expression in seasonal allergic rhinitis
ConclusionThe present study demonstrates the presence and function of LEAP‐2, LL‐37 and RNase7 in tonsils. Moreover, a downregulation of LEAP‐2 and RNase7 is seen in SAR patients, indicating that allergic individuals may be more susceptible to respiratory tract infections due to an impaired antimicrobial defense.This article is protected by copyright.
