BACKGROUND Burkholderia pseudomallei, the causative agent of melioidosis, is generally considered to be acquired via inhalation of dust or water droplets from the environment. In this study, we show that infection of the nasal mucosa is potentially an important portal of entry in melioidosis. METHODS After intranasal inoculation of mice, infection was(More)
The pathogenic clinical strain NCTC11168 was the first Campylobacter jejuni strain to be sequenced and has been a widely used laboratory model for studying C. jejuni pathogenesis. However, continuous passaging of C. jejuni NCTC11168 has been shown to dramatically affect its colonisation potential. Glycan array analysis was performed on C. jejuni NCTC11168(More)
Burkholderia pseudomallei, the causative agent of melioidosis, is endemic to Southeast Asia and northern Australia. Clinical manifestations of the disease are diverse, ranging from chronic localized infection to acute septicaemia, with death occurring within 24-48 h after the onset of symptoms. Definitive diagnosis of melioidosis involves bacterial culture(More)
Burkholderia pseudomallei is the causative agent of melioidosis, a potentially fatal disease endemic or emerging world-wide. Here we report unmarked allele-replacement mutagenesis using efficient sacB counter-selection. Despite being genotypically sacB(+), most commonly used B. pseudomallei strains are sucrose-resistant and efficient sacB counter-selection(More)
