Detection on surfaces and in Caco-2 cells of Campylobacter jejuni cells transformed with new gfp, yfp, and cfp marker plasmids

Article Abstract:

Researchers describe the use of three Champylobacter shuttle vectors based on the green, yellow, or cyan fluorescent protein reporter gene that can be used to identify the organism in meat and poultry samples. Cells that are tagged with these genes remain fluorescent for several days.

Comparison of survival of campylobacter jejuni in the phyllosphere with that in the rhizosphere of spinach and radish plants

Article Abstract:

Thermophillic campylobacter species, campylobacter coli, campylobacter lari and campylobacter jejuni are known to cause gastrointestinal illness around US, UK and other European countries. The ability of campylobacter jejuni to utilize organic compounds present in leaf or root exudates and to survive in plant environment are examined.

Speciation of Campylobacter coli, C. jejuni, C. helveticus, C. lari, C. sputorum, and C. upsaliensis by matrix-assisted laser desorption ionization-time of flight mass spectrometry

Article Abstract:

Multiple strains of Campylobacter coli, C. jejuni, C. helveticus, C. lari, C. sputorum and C. upsaliensis isolated from animal, clinical or food samples were analyzed by matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS). MALDI-TOF MS provided an accurate, sensitive and rapid method for identification of multiple Campylobacter species relevant to public health and food safety.
