Elucidation of the RamA Regulon in Klebsiella pneumoniae Reveals a Role in LPS Regulation [PDF]
Klebsiella pneumoniae is a significant human pathogen, in part due to high rates of multidrug resistance. RamA is an intrinsic regulator in K. pneumoniae established to be important for the bacterial response to antimicrobial challenge; however, little ...

Lipopolysaccharide is a frequent contaminant of plasmid DNA preparations and can be toxic to primary cells in the presence of adenovirus [PDF]
Endotoxin (lipopolysaccharide, LPS) is commonly found as a contaminant in plasmid DNA preparations. We demonstrate here that the quantities of LPS typically contaminating DNA preparations can generate a toxicity to primary cells (primary human skin ...

Escenario actual de la resistencia a la colistina mediada por plásmidos en América Latina [PDF]
Colistin resistance can occur by chromosomal mutations and by acquisition of plasmid-carrying determinants, mainly mcr-1. In the recent years, we have observed the outburst of this resistance gene in our region. Due to the risk of the rapid dissemination

Polymyxin B-induced skin and nail hyperpigmentation in an adult
Polymyxin B is a reserve drug for resistant gram-negative bacterial infections. A rare side effect of polymyxin B is cutaneous hyperpigmentation, which characteristically involves face and neck. This is commonly reported in pediatric population.

Structural insights into Escherichia coli polymyxin B resistance protein D with X-ray crystallography and small-angle X-ray scattering [PDF]
BACKGROUND: Polymyxin B resistance protein D (PmrD) plays a key role in the polymyxin B-resistance pathway, as it is the signaling protein that can act as a specific connecter between PmrA/PmrB and PhoP/PhoQ.

Peptides as potent antimicrobials tethered to a solid surface: Implications for medical devices [PDF]
Medical devices are an integral part of therapeutic management; despite their importance, they carry a significant risk of microbial infection. Bacterial attachment to a medical device is established by a single, multiplying organism, leading to ...
