Surface expression, single-channel analysis and membrane topology of recombinant Major Outer Membrane Protein [PDF]
, 2005 Background Chlamydial bacteria are obligate intracellular pathogens containing a cysteine-rich porin (Major Outer Membrane Protein, MOMP) with important structural and, in many species, immunity-related roles.

Plant, Cell &Environment, EarlyView.ABSTRACT Plants can perceive specific elicitors in the oral secretions (OS) of herbivorous insects and respond by increasing their defences. Whether plants can discriminate among similar herbivorous insect species and differentially modulate their defence responses against them is largely unknown.

Holling Type I versus Holling Type II functional responses in Gram-negative bacteria [PDF]
, 2018 We consider how the double-membrane structure of the cell envelope of Gram-negative bacteria affects its functional response, which is the mathematical relationship that expresses how the nutrient uptake flux depends on environmental conditions.

Antibiotic Transport through Porins [PDF]
Biophysical Journal, 2014 The emergence and dissemination of coordinated resistance mechanism (MDR) underline the importance to understand the rate limiting steps in antibiotic action. Here OmpF porin from E. coli is used as an example to demonstrate what limits the penetration of carbapenems.

Viable but Nonculturable State, a Survival Strategy for Salmonella in Aquatic Environments
Water and Environment Journal, EarlyView.Transition of Salmonella from a culturable state to a viable but nonculturable state under various environmental stresses and current methods for detecting viable Salmonella in environmental samples. ABSTRACT In the relentless battle for survival, Salmonella has evolved mechanisms to withstand harsh conditions such as extreme temperatures, fluctuating ...

Single or in combination antimicrobial resistance mechanisms of Klebsiella pneumoniae contribute to varied susceptibility to different carbapenems. [PDF]
PLoS ONE, 2013 Resistance to carbapenems has been documented by the production of carbapenemase or the loss of porins combined with extended-spectrum β-lactamases or AmpC β-lactamases.

Role of metal-dependent regulation of ESX-3 secretion in intracellular survival of Mycobacterium tuberculosis [PDF]
, 2016 More people die every year from Mycobacterium tuberculosis infection than from infection by any other bacterial pathogen. Type VII secretion systems (T7SS) are used by both environmental and pathogenic mycobacteria to secrete proteins across their ...
