Article Abstract

Background: sequence type 131 (ST131) is a successful clonal group that has dramatically spread during the last decades and is considered an important driver for the rapid increase of quinolone resistance in .

Methods: Risk factors for rectal colonization by ST131 (irrespective of ESBL production) were investigated in 64 household members (18 were colonized) and 54 hospital contacts (HC; 10 colonized) of 34 and 30 index patients with community and nosocomial infection due to these organisms, respectively, using multilevel analysis with a p limit of < 0.1.

Result: Colonization among household members was associated with the use of proton-pump inhibitors (PPI) by the household member (OR = 3.08; 95% CI: 0.88-10.8) and higher age of index patients (OR = 1.05; 95% CI; 1.01-1.10), and among HC, with being bed-ridden (OR = 21.1; 95% CI: 3.61-160.0) and having a urinary catheter (OR = 8.4; 95% CI: 0.87-76.9).

Conclusion: Use of PPI and variables associated with higher need of person-to-person contact are associated with increased risk of rectal colonization by ST131. These results should be considered for infection control purposes.

Background: Escherichia coli ST131 and clade H30Rx are the most prevalent extended-spectrum β-lactamase-producing E. coli (ESBL-EC) causing bacteremia and urinary tract infections globally and in Sweden. Previous studies have linked ST131-H30Rx with septic shock and mortality, as well as prolonged carriage.

In this 4-month-long prospective observational study, we explored the colonization rate of extended-spectrum β-lactamase-producing (ESBL-EC) in the patient and ward environment of an intensive care unit (ICU). Additionally, we evaluated the risk factors for colonization and analyzed genomic characteristics and modes of transmission of isolates. Clinical samples were collected from patients and the environment to isolate and screen strains.

Urinary tract infections (UTIs) are a leading cause of illness in children and adults of all ages, with uropathogenic (UPEC) being the primary agent responsible. During colonization and subsequent infection of the urinary tract (UT), UPEC requires the expression of genes associated with virulence, such as those that encode the fimbrial adhesins FimH, PapG, and CsgA, as well as the presence of the TosA protein and the flagellar appendages of the bacteria. However, for colonization and infection to be successful, UPEC must overcome the host's immunological barriers, such as physical barriers, expressed peptides and proteins, and immune cells found in the UT.

Living in high-endemic regions increases the risk of intestinal colonization by multidrug-resistant Enterobacterales (MDR-Ent). This study investigated Swiss expatriates residing abroad (≥ 3 months) to assess their colonization status upon returning to Switzerland. Selective culture-based methods were implemented to detect third-generation cephalosporins- (3GC-R), carbapenems- (CR), and colistin-resistant (COL-R) strains.

Introduction: Escherichia coli has emerged as an important pathogen in urinary tract infections (UTIs) due to the rapid acquisition of antibiotic resistance genes. This enhances the ability of E. coli to colonize and creates therapeutic challenges within the healthcare system.
