Functional analysis of resiniabactin transport genes of Tersinia enterocolitica

Article Abstract:

Yersiniabactin transport genes of Yersinia enterocolitica have been studied using functional analysis.Within the genus Yersinia, the high-pathogenicity group, to which Y. enterocolitica O:8, biogroup (BG) IB, strain WA-C belongs, carries the high-pathogenicity island (HPI) made up of a conserved core region and an AT-rich variable part. The strain referred to has iron-repressible gene, irp1-9, and fyuA. The CAS siderophore indicator supplement in chrome azurol S (CAS) agar can induce Ybt biosynthesis and fyuA gene expression independent of the presence of the outer membrane siderophore receptor.

A new simvastatin (mevinolin)-resistance marker from Haloarcula hispanica and a new Haloferax volcanii strain cured of plasmid pHV2

Article Abstract:

This paper describes the isolation, cloning, sequence, and incorporation of the mavinolin-resistance marker, derived from Haloarcula hispanica, into Haloferax volcanii. Data indicate that the plasmids carrying the new resistant marker are stable and exhibit low recombination with the chromosome of H. volcanii.

Xenorhabdus bovienii T228 phase variation and virulence are independent of RecA function

Article Abstract:

Results demonstrate that recA gene is not involved in the RecA-mediated processes such as phase variation, expression of colony pleomorphism characteristics, and virulence factors that kill susceptible larvae in nematode associated bacterium Xenorhabdus bovienii T228.
