Meteorological data show that disastrous floods are increasingly frequent and more severe in recent years, perhaps due to climatic changes such as global warming. During and after a flood disaster, traumatic injuries, communicable diseases, chemical exposures, malnutrition, decreased access to care,
Sudden unexplained death syndrome (SUDS) among young healthy Thai construction workers in Singapore has been given much publicity recently. From May 1982 to July 1990, 226 SUDS were reported among them. In this article we review and compare studies on SUDS in the United States and South-east Asia.
The nitrogen-related phosphoenolpyruvate phosphotransferase system (PTS(Ntr) ) is involved in controlling ammonia assimilation and nitrogen fixation. The additional role of PTS(Ntr) as a regulatory link between nitrogen and carbon utilization in Escherichia coli is assumed to be closely related to
Burkholderia pseudomallei is a soil-dwelling bacterium and the cause of melioidosis, which kills an estimated 89,000 people per year worldwide. Agricultural workers are at high risk of infection due to repeated exposure to the bacterium. Little is known about the soil physicochemical properties
A superoxide dismutase (SOD) gene from Burkholderia pseudomallei, the causative agent of melioidosis, was cloned and expressed in Escherichia coli, and its product was functionally and physically characterized. The gene has an open-reading frame of 579 bp. The deduced amino acid sequence has 192
Factors responsible for the spatial and temporal clustering of Burkholderia pseudomallei in the environment remain to be elucidated. Whilst laboratory based experiments have been performed to analyse survival of the organism in various soil types, such approaches are strongly influenced by
Type 2 diabetes mellitus is a major risk factor for melioidosis, which is caused by Burkholderia pseudomallei. Our previous study has shown that polymorphonuclear neutrophils (PMNs) from diabetic subjects exhibited decreased functions in response to B. pseudomallei. Here we investigated the
