Small regulatory RNA (sRNAs) are key mediators of posttranscriptional gene control in
bacteria. Assisted by RNA-binding proteins, a single sRNA often modulates the expression …

Chronic and recurrent bacterial infections are frequently associated with the formation of
biofilms on biotic or abiotic materials that are composed of mono-or multi-species cultures of …

Bacterial pathogens require the iron-containing cofactor heme to cause disease. Heme is
essential to the function of hemoproteins, which are involved in energy generation by the …

In bacteria–host interactions, competition for iron is critical for the outcome of the infection.
As a result of its redox properties, this metal is essential for the growth and proliferation of …

Biofilms are structured microbial communities that are the leading cause of numerous
chronic infections which are difficult to eradicate. Within the lungs of individuals with cystic …

While iron is essential to sustain growth, its excess can be detrimental to the cell by
generating highly toxic reactive oxygen species. Regulation of iron homeostasis thus plays a …

Pseudomonas aeruginosa is an opportunistic pathogen able to infect any human tissue.
One of the reasons for its high adaptability and colonization of host tissues is its capacity of …

Background Pseudomonas aeruginosa is one of the most common pathogens that lead to
fatal human infection. This Gram-negative pathogen has evolved complex drug resistance …

The extensive use of nanoparticles (NPs) in industrial processes makes their potential
release into the environment an issue of concern. Ag and ZnO NPs are among the most …

During infection, bacterial pathogens successfully sense, respond and adapt to a myriad of
harsh environments presented by the mammalian host. This exquisite level of adaptation …
