The LysR-family regulator MexT modulates the expression of the MexEF-OprN efflux system in the human pathogen Pseudomonas aeruginosa. Recently, we demonstrated that MexT regulates certain virulence phenotypes, including the type-three secretion system and early attachment independent of its role in regulating MexEF-OprN. In this study, transcriptome… (More)
Mechanisms of protective immunity to Staphylococcus aureus infection in humans remain elusive. While the importance of cellular immunity has been shown in mice, T cell responses in humans have not been characterised. Using a murine model of recurrent S. aureus peritonitis, we demonstrated that prior exposure to S. aureus enhanced IFNγ responses upon… (More)
Mycobacterium chimaera is an opportunistic human pathogen implicated in both pulmonary and cardiovascular infections. Here, we report the draft genome sequences of three strains isolated from human respiratory specimens.
Extensively drug-resistant (XDR) tuberculosis has now been described in >90 countries worldwide. The first case of XDR tuberculosis (XDR-TB) in New Zealand was recorded in 2010. We report the draft whole-genome sequence of the New Zealand isolate, NZXDR1, and describe a number of single-nucleotide polymorphisms that relate to drug resistance.
Extensive drug resistance is an emerging threat to the control of tuberculosis (TB) worldwide, even in countries with low TB incidence. We report the draft whole-genome sequence of the first reported extensively drug-resistant TB (XDR-TB) strain isolated in Ireland (a low-incidence setting) and describe a number of single-nucleotide variations that… (More)
Whole-genome sequencing of 24 Proteus mirabilis isolates revealed the clonal expansion of two cefoxitin-resistant strains among patients with community-onset infection. These strains harboured bla CMY-2 within a chromosomally located integrative and conjugative element and exhibited multidrug resistance phenotypes. A predominant strain, identified in 18… (More)
Multidrug resistance constitutes a threat worldwide to the management of tuberculosis (TB). We report the draft whole-genome sequence of a lineage 3 (East-African Indian) isolate of Mycobacterium tuberculosis which presented as multidrug resistant in New Zealand, and describe a number of single-nucleotide polymorphisms in genes relating to drug resistance.
INTRODUCTION Globally, extra-intestinal pathogenic Escherichia coli are one of the predominant causative agents of bacteraemia. CASE PRESENTATION This case report outlines a presentation of community-acquired pyelonephritis and secondary bloodstream infection in an 81-year-old man. Laboratory investigations revealed that the causative isolate was a… (More)
We report here the draft whole-genome sequence of a drug-susceptible lineage 3 (East-African Indian) isolate of Mycobacterium tuberculosis from New Zealand (NZ3DS1) and compare it to a multidrug-resistant lineage 3 isolate (NZ3MDR1) with an identical 24-locus mycobacterial interspersed repetitive-unit-variable-number tandem-repeat profile.
The Rangipo genotype of the Mycobacterium tuberculosis complex has been associated with a number of tuberculosis (TB) outbreaks in New Zealand. We report here the draft whole-genome sequence of a representative isolate of this strain.
