Contribution of siderophore systems to growth and urinary tract colonization of asymptomatic bacteriuria Escherichia coli [PDF]

, 2012
The molecular mechanisms that define asymptomatic bacteriuria (ABU) E. coli colonization of the human urinary tract remain to be properly elucidated. Here we utilize ABU E.

Geographic containment and virulence‐resistance trade‐offs drive the evolution of hypervirulent Klebsiella pneumoniae

iMeta, Volume 4, Issue 5, October 2025.
The global emergence of hypervirulent, carbapenem‐resistant Klebsiella pneumoniae (hvCRKP) poses a paradox: why do such dangerous clones remain geographically confined? By analyzing over 2500 CC23 genomes across 90 years, we uncover a core evolutionary constraint—virulence and resistance rarely coexist without trade‐offs. Potent carbapenemases (blaKPC,

Characterization of an emergent clone of enteroinvasive Escherichia coli circulating in Europe [PDF]

, 2016
Enteroinvasive Escherichia coli (EIEC) cause intestinal illness indistinguishable from that caused by Shigella, mainly in developing countries. Recently an upsurge of cases of EIEC infections has been observed in Europe, with two large outbreaks ...

Genomic Characterization of Pan‐Drug Resistant Klebsiella pneumoniae KPNW Isolated From UTI Patient in Bangladesh

MicrobiologyOpen, Volume 14, Issue 5, October 2025.
Klebsiella pneumoniae isolate KPNW showed resistance to all clinically relevant antibiotics. Upon whole genome sequencing and characterization, we detected a large number of antimicrobial resistance genes, resistance‐associated point mutations, virulence determinants, heavy metal resistance genes, and mobile genetic elements in errorits genome ...

Host Imprints on Bacterial Genomes-Rapid, Divergent Evolution in Individual Patients [PDF]

, 2010
Bacteria lose or gain genetic material and through selection, new variants become fixed in the population. Here we provide the first, genome-wide example of a single bacterial strain’s evolution in different deliberately colonized patients and the ...

Role of tol genes in cloacin DF13 susceptibility of Escherichia coli K-12 strains expressing the cloacin DF13-aerobactin receptor IutA

Journal of Bacteriology, 1993
IutA is the outer membrane protein receptor for ferric aerobactin and the bacteriocin cloacin DF13. Although the same receptor is shared, ferric aerobactin transport across the outer membrane in Escherichia coli is TonB dependent, whereas cloacin DF13 transport is not. We have recently observed that tolQ is required for cloacin DF13 susceptibility (J.A.

An analytical model to predict the mass loading of air cleaners in typical indoor environments and to estimate the service interval from standardized filter loading tests

Indoor Environments
For indoor air cleaners, especially those using electret filters, it is known that the clean air delivery rate (CADR) can strongly decrease over time due to loading of the filters with particles.
