Prevalence and Population Diversity of Isolated from Dairy Cattle Farms in the Cantabria Region of Spain.

is an opportunistic pathogen that is widely distributed in the environment. Here we show the prevalence and transmission of in dairy farms in the Cantabria region, on the northern coast of Spain. A total of 424 samples was collected from 14 dairy farms (5 organic and 9 conventional) and 211 isolates were recovered following conventional microbiological methods.

New Sequence Type ST3449 in Multidrug-Resistant Isolates from a Cystic Fibrosis Patient.

is one of the most critical bacterial pathogens associated with chronic infections in cystic fibrosis patients. Here we show the phenotypic and genotypic characterization of five consecutive multidrug-resistant isolates of collected during a month from a CF patient with end-stage lung disease and fatal outcome. The isolates exhibited distinct colony morphologies and pigmentation and differences in their capacity to produce biofilm and virulence potential evaluated in larvae of .

The acid adaptive tolerance response in Campylobacter jejuni induces a global response, as suggested by proteomics and microarrays.

Campylobacter jejuni CI 120 is a natural isolate obtained during poultry processing and has the ability to induce an acid tolerance response (ATR) to acid + aerobic conditions in early stationary phase. Other strains tested they did not induce an ATR or they induced it in exponential phase. Campylobacter spp.

Release of Cell-Free Ice Nucleators from Three Recombinant Ice Zymomonas mobilis Strains.

Background/aims: This work is a study of the ability of three recombinant Zymomonas mobilis strains to release ice nucleators into their growth medium.

Methods: The recombinant ice(+)Z. mobilis cells were tested for their ability to produce cell-free ice nucleators, under three different growth temperatures and three different glucose concentrations.

Interaction between relaxase MbeA and accessory protein MbeC of the conjugally mobilizable plasmid ColE1.

MbeA and MbeC are two key proteins in plasmid ColE1 conjugal mobilization. Isothermal titration calorimetry was used to detect and quantify an interaction between MbeA and MbeC. As a result of this interaction, the affinity of MbeA for single stranded DNA increased.
