Antibacterial Potential of Actinomycete Extracts and Characterization of β‐Lactamase‐Producing Multidrug‐Resistant Uropathogenic Escherichia coli

MicrobiologyOpen, Volume 14, Issue 6, December 2025.
Antibacterial Potential of Actinomycete Extracts Against Multidrug‐Resistant Escherichia coli in Babil Province, Iraq. ABSTRACT The increasing prevalence of multidrug‐resistant (MDR) uropathogenic Escherichia coli (UPEC) strains, particularly those producing β‐lactamase enzymes, complicates urinary tract infection (UTI) treatment and poses a ...

An exploratory study of dog park visits as a risk factor for exposure to drug-resistant extra-intestinal pathogenic E. coli (ExPEC)

, 2015
Background Extraintestinal pathogenic E. coli (ExPEC) are common causative agents of urinary tract infections in humans. Dogs have been found to harbor ExPEC. This study tested stool samples from dogs (n = 16), the shoes of dog park visitors (n = 16) and

Virulence factors, prevalence and potential transmission of extraintestinal pathogenic Escherichia coli isolated from different sources: recent reports

Gut Pathogens, 2019
Extraintestinal pathogenic E. coli (ExPEC) are facultative pathogens that are part of the normal human intestinal flora. The ExPEC group includes uropathogenic E. coli (UPEC), neonatal meningitis E. coli (NMEC), sepsis-associated E.

Combined analysis of primary lymphoid tissues' transcriptomic response to extra-intestinal Escherichia coli (ExPEC) infection

Developmental & Comparative Immunology, 2016
Avian pathogenic Escherichia coli (APEC), an extraintestinal pathogenic E. coli (ExPEC), constitutes an animal health and a potential zoonotic risk. Most studies focus on the response of a single tissue to APEC infection. Understanding interactions among lymphoid tissues is of importance in controlling APEC infection. Therefore, we studied bone marrow,

Isolation and purification of ExPEC EVs from different ST strains.

, 2022
(A) Growth curves of three ExPEC strains. APEC strain FY26, APEC strain CBE59, and UPEC strain CFT073 were cultured in LB broth at 37°C. Bacterial growth was monitored by measuring the OD600. Two-way ANOVA was used to evaluate statistical significance (P

Pandemic extra-intestinal pathogenic Escherichia coli (ExPEC) clonal group O6-B2-ST73 as a cause of avian colibacillosis in Brazil. [PDF]

, 2017
Extra-intestinal pathogenic Escherichia coli (ExPEC) represent an emerging pathogen, with pandemic strains increasingly involved in cases of urinary tract infections (UTIs), bacteremia, and meningitis. In addition to affecting humans, the avian pathotype

Increased proportion of cytoplasmic vesicles in ExPEC EVs caused more-severe mitochondrial dysfunction and apoptosis in macrophages.

, 2022
(A) Mitochondrial membrane potential (ΔΨm) was determined with JC-1 dye and flow cytometry. Bone-marrow-derived macrophages (BMDMs) were treated with FY26 EVs (50 μg/mL) or PBS for 0, 2, 4, 8, 12 or 24 h and labeled with JC-1.

Conditions for biofilm formation in Extraintestinal Pathogenic E. coli (ExPEC) [PDF]

Sepsis is a complex multi-organ state caused by a dysfunctional immune response to infection. Recent estimates suggest an incidence of around 360 cases per 100,000 population per year, resulting in approximately 20% of all mortality rates. Bacteria cause
