The worldwide spread of E. coli ST131 has significantly contributed to the dissemination of E. coli producing extended-spectrum β-lactamases (ESBL). In a French University hospital, we assessed the molecular features of ESBL-producing E. coli and identified risk factors in patients for colonization or infection with E. coli ST131. Over a 2-year period (2015-2017), each patient with at least one clinical isolate or one screening isolate positive with ESBL-producing E. coli were included (n = 491). The ST131 clonal group accounted for 17.5% (n = 86) of all ESBL-producing E. coli and represented 57.3% isolates of phylogroup B2. FimH-based sub-typing showed that 79.1% (68/86) of ST131 isolates were fimH30, among which 67.6% (n = 46), 20.6% (n = 14) and 11.8% (n = 8) isolates harbored genes encoding the ESBL CTX-M-15, CTX-M-27, and CTX-M-14, respectively. The multivariate analysis identified two factors independently associated with ST131 ESBL-producing E. coli isolates: infection (Odds ratio [OR] = 1.887, 95% confidence interval [CI]: 1.143-3.115; p = 0.013) and community acquisition (OR = 2.220, 95% CI: 1.335-3.693; p = 0.002). In conclusion, our study confirmed the predominance of ST131 clonal group among ESBL-producing E. coli and the difficulty to identify common risk factors associated with carriage of this pandemic clonal group.

Urinary tract infections are a common condition affecting people globally, with multidrug-resistant (MDR) Escherichia coli (E. coli) being a major causative agent. Antimicrobial susceptibility profiling was performed using the VITEK 2 automated system for 1254 E.

The contamination of retail meat with antibiotic-resistant bacteria poses a substantial public health risk because of the potential spread of these bacteria within communities. The contamination of retail meat with extended-spectrum beta-lactamase (ESBL)-producing bacteria was investigated in four cities in Vietnam using real-time PCR, employing ESBL marker genes. This method provides a more comprehensive assessment of ESBL-producing bacterial contamination in meat samples than culture-based methods because it directly detects resistance genes from the extracted sample DNA.

The study was conducted to detect the occurrence and phenotypic resistance pattern of ESBL-producing Enterobacteriaceae in livestock using docking based analysis to reveal the classes of antibiotics against which ESBL-producers are active. Rectal swabs from healthy cattle (n=100), goats (n=88), pigs (n=66) were collected from backyard farms in Andaman and Nicober island (India). In total, 304 isolates comprising E.

Cases of antibiotic-resistant () infections are becoming increasingly frequent and represent a major threat to our ability to treat cancer patients. The emergence of antimicrobial resistance threatens the treatment of infections. In this study, the antimicrobial profiles, virulent genes, and the frequency of extended-spectrum beta-lactamase (ESBL) gene carriage in fecal isolates from cancer patients at the Laquintinie Hospital in Douala (Cameroon) were determined.

The transmission of antibiotic resistance (AR) from farm animals to healthy human communities, beyond the food chain, is often facilitated by biological vectors, notably houseflies (Musca domestica). This study aimed to evaluate the role of M. domestica collected from commercial broiler chicken farms as a carrier of multidrug-resistant (MDR), extended-spectrum β-lactamase (ESBL)-producing Escherichia coli.
