Cloning and characterization of the iron uptake gene iutA from avian Escherichia coli [PDF]

Brazilian Archives of Biology and Technology, 2008
The aim of this work was to isolate, clone and characterize the iron uptake gene iutA from avian pathogenic E. coli (APEC). The iutA gene was isolated from the strain APEC 9, serotype O2:H9, which was cloned in the expression vector pET101/D-TOPO.

The ferric aerobactin receptor IutA, a protein isolated on agarose column, is not essential for uropathogenic Escherichia coli infection El receptor de aerobactina IutA, una proteína aislada en columna de agarosa, no es esencial para la infección por Escherichia coli uropatógena O receptor de aerobactina IutA, uma proteína isolada em coluna de agarose, não é essencial para a infecção por Escherichia coli uropatogênica [PDF]

Revista Latino-Americana de Enfermagem, 2012
Although many proteins have been described involved in Escherichia coli colonization and infection, only few reports have shown lectins as important components in these processes. Because the mechanisms underlying E.

Rising Cellular Immune Response after Injection of pVax/iutA: A Genetic DNA Cassette as Candidate Vaccine against Urinary Tract Infection

Iranian Journal of Public Health, 2016
Background: Uropathogenic Escherichia coli (UPEC) are major bacterial agent of Urinary Tract Infection (UTI). This infection is more prevalent among women because approximately half of all women will experience a UTI in their life-time and near a quarter

Evolutionary Origins and Virulence Determinants of ST25 Hypervirulent <i>Klebsiella pneumoniae</i> in Swine: Genomic Insights and Functional Validation. [PDF]

Transbound Emerg Dis
The global spread of multidrug‐resistant hypervirulent Klebsiella pneumoniae (MDR‐HvKp), among which carbapenem‐resistant strains are of major concern, poses a severe threat to public health due to its high mortality rate and extremely limited treatment options.

Assessment of Hypervirulent Klebsiella pneumoniae Isolates Using Multilocus Sequence Typing in West of Iran. [PDF]

Microbiologyopen
This study identified eight novel sequence types (STs) of hypervirulent Klebsiella pneumoniae using MLST in western Iran. The findings highlight the genetic diversity and public health threat posed by hvKP strains. Phenotypic and genotypic methods, including PCR and MLST, were used to identify hypervirulent Klebsiella pneumoniae isolates in western ...

Virulence, Phylogenetic Grouping, and Antimicrobial Resistance Traits of Extraintestinal <i>Escherichia coli</i> in Clinical Isolates From Northwest Mexico. [PDF]

Int J Microbiol
Escherichia coli is a highly diverse bacterial species that is canonically commensal; however, its genomic characteristics have enabled its evolution into pathogens capable of causing extraintestinal infections (ExPEC), which pose significant clinical challenges because of the variety of sites that can infect (mainly the urinary tract) and the ...

High Rates of Antimicrobial Resistance and Emergence of High-Risk Clones in Community-Acquired Uropathogenic Escherichia coli. [PDF]

Microbiologyopen
A total of 98 E. coli isolates from community‐acquired UTIs were analyzed, revealing high resistance rates to trimethoprim‐sulfamethoxazole and fluoroquinolones. Phylogenetic group B2 was the most prevalent and associated with increased virulence, while ST1193 emerged as the dominant MDR clone.

Immunological variants of the aerobactin-cloacin DF13 outer membrane protein receptor IutA among enteric bacteria [PDF]

Infection and Immunity, 1994
Mouse monoclonal antibodies (MAbs) were generated against a 76-kDa IutA receptor of pathogenic avian Escherichia coli 15972. Six of the eight IutA-specific MAbs isolated (AB1 to AB6) were shown to be directed toward membrane-exposed conformational epitopes, although they did not interfere with the uptake of ferric aerobactin and cloacin DF13 as ...
