The absence of intervening sequences in 23S rRNA genes of Campylobacter coli isolates from turkeys is a unique attribute of a cluster of related strains which also lack resistance of Erythromycin

Article Abstract:

The characterization of 104 strains of Campylobacter coli from turkeys, representing 27 different multilocus sequence typing-based sequence types (STs) in terms of transcribed intervening sequence (IVS) content and erythromycin susceptibility is presented. The findings suggest that the absence of IVS in Campylobacter coli from turkeys is characteristic of a unique clonal group of erythromycin-susceptible strains and that IVS could be acquired by these strains through natural transformation to erythromycin resistance.

Natural transformation-mediated transfer of erythromycin resistance in Campylobacter coli strains from turkeys and swine

Article Abstract:

Transformation-mediated acquisition of erythromycin resistance by genotypically diverse Campylobacter coli strains from turkeys and swine, with total genomic DNA from erythromycin-resistant C. Coli of either turkey or swine origin used as a donor was investigated. The findings suggested that natural transformation has the potential to contribute to the dissemination of high-level resistance to erythromycin among C. coli strains colonizing meat animals.

Putative transposases conserved in Exiguobacterium isolates from ancient Siberian permafrost and from contemporary surface habitats

Article Abstract:

Exiguobacterium spp. is isolated from or molecularly detected in an impressive diversity of habitats, including Artic permafrost, mats of Lake Fryxell in the Antarctic, surface water, several types of food processing plants, and a range of saline or alkaline environments. The detection of highly conserved putative transposases in the genomes of Exiguobacterium spp. from ancient permafrost and from widely diverse environments is described.
