Uropathogenic Escherichia coli (UPEC) causes serious infections in people at risk and has a significant environmental prevalence due to contamination by human and animal excreta. In developing countries, UPEC assumes importance in certain dwellings because of poor community/personal hygiene and exposure to contaminated water or soil. We report the complete(More)
The bacterial genus Paracoccus is comprised of metabolically versatile organisms having diverse degradative capabilities and potential industrial and environmental applications for bioremediation in particular. We report a de novo-assembled sequence and annotation of the genome of a novel isolate of Paracoccus denitrificans originally sourced from coal mine(More)
The diverse clinical outcomes of colonization by Helicobacter pylori reflect the need to understand the genomic rearrangements enabling the bacterium to adapt to host niches and exhibit varied colonization/virulence potential. We describe the genome sequences of the two serial isolates, H. pylori 2017 and 2018 (the chronological subclones of H. pylori 908),(More)
Helicobacter pylori is a genetically diverse and coevolved pathogen inhabiting human gastric niches and leading to a spectrum of gastric diseases in susceptible populations. We describe the genome sequence of H. pylori 908, which was originally isolated from an African patient living in France who suffered with recrudescent duodenal ulcer disease. The(More)
Among enteric pathogens, Salmonella enterica serovar Typhi is responsible for the largest number of food-borne outbreaks and fatalities. The ability of the pathogen to cause systemic infection for extended durations leads to a high cost of disease control. Chronic carriers play important roles in the evolution of Salmonella Typhi; therefore, identification(More)
A decade since the availability of Mycobacterium tuberculosis (Mtb) genome sequence, no promising drug has seen the light of the day. This not only indicates the challenges in discovering new drugs but also suggests a gap in our current understanding of Mtb biology. We attempt to bridge this gap by carrying out extensive re-annotation and constructing a(More)
Many of the developing countries of the Southeast Asian region are significantly affected by endemic typhoid fever, possibly as a result of marginal living standards. It is an important public health problem in countries such as Papua New Guinea, which is geographically close to some of the foci of endemicity in Asia. The severity of the disease varies in(More)
Salmonella enterica serovar Typhi is the causative agent of typhoid fever, which causes nearly 21.7 million illnesses and 217,000 deaths globally. Herein, we describe the whole-genome sequence of the Salmonella Typhi strain ST0208, isolated from a sporadic case of typhoid fever in Kuala Lumpur, Malaysia. The whole-genome sequence and comparative genomics(More)
The human gastric pathogen, Helicobacter pylori, colonizes more than 50% of the world population and is a well-known cause of peptic ulcer disease. H. pylori has been epidemiologically linked to various other diseases, among which its putative link with certain complex diseases such as type 1 diabetes mellitus (T1DM) is of interest. Although antibiotic(More)
