Two groups of Escherichia coli were assayed to evaluate hydrophobic characters and the secretion of enzymes and cytotoxic factors. Group 1 included strains isolated from the urine of patients with lower urinary tract infection (UTI) and group 2 included strains from the same sample of asymptomatic subjects. The bacterial hydrophobicity was similar in the two groups and related to their adhesion to plastic surfaces, while both cytotoxic factors (demonstrated using a microscopic and a spectrophotometric technique) and hydrolysing enymes were secreted more by the first group of E. coli. The superior production of these factors may be important in the pathogenesis and in the development of symptomatic UTI infections.

Emergence and polyclonal dissemination of NDM-5/OXA-181 carbapenemase-producing Escherichia coli in the French Indian Ocean territories.

Laboratoire de Bactériologie, CHU Félix Guyon, Allée des Topazes, 97400, Saint-Denis, La Réunion, France.
Aim: Located in the Southwest Indian Ocean area (SIOA), the two French overseas territories (FOTs) of Reunion and Mayotte islands are heavily impacted by antimicrobial resistance. The aim of this study was to investigate all cases of NDM-5 and OXA-181 carbapenemase-producing Escherichia coli (CPEc) in these two FOTs between 2015 and 2020, to better understand the regional spread of these last-line treatment resistant bacteria.

Objective: Bacterial gastroenteritis is a significant public health concern, capable of causing severe infections. Among the various pathogens involved, those belonging to the Enterobacteriaceae family are the most frequently isolated and associated with gastrointestinal disorders. This study aimed to investigate the prevalence of common diarrheagenic Enterobacteriaceae in Iran over the past two decades, from 2000 to 2023.

Aim: To investigate the nucleotide sequences associated with transposable elements carrying bla allelic variants as potential markers for the transmission of antimicrobial resistance genes between domestic animals, humans and the environment.
Materials & Methods: We conducted whole-genome sequencing and analyzed the nucleotide sequences of most abundant bla allelic variants (bla, bla, and bla) in commensal Escherichia coli ( = 20) from household members in Quito and uropathogenic E. coli (UPEC) ( = 149) isolated from nine clinics in Quito, Ecuador.
Fabricating an antioxidant and bacteriostatic soy protein isolate film double-crosslinked via dialdehyde cellulose nanofibers and Tara tannins for beef tallow and cooked pork preservation.

Although Tara tannins (TT) have given soy protein isolate (SPI) film antioxidant properties, the mechanical and barrier properties were not significantly improved. In this work, dialdehyde cellulose nanofibers (DACNF) were obtained through oxidation using sodium periodate and incorporated into SPI film with TT to obtain antioxidant and bacteriostatic properties. With increased DACNF content, the anti-swelling, mechanical and barrier properties of SPI film were enhanced due to a double-crosslinked structure based on the covalent and hydrogen bonds formed between DACNF, TT and SPI.

Introduction: Cefiderocol is a parenteral catechol-type siderophore cephalosporin, which has been approved for the treatment of gram-negative bacterial infections. Its activity among the carbapenem-resistant gram negative bacilli (CR-GNBs) in India is largely unknown.
Methodology: We tested in-vitro susceptibility of cefiderocol in 84 CR-GNB [ carbapenem-resistant Acinetobacter baumannii (CRAB), carbapenem-resistant Pseudomonas aeruginosa (CRPA) , carbapenem-resistant Escherichia coli (CREC) and carbapenem-resistant Klebsiella pneumoniae (CRKP)] by broth microdilution(BMD) and disc diffusion (DD) using Clinical and Laboratory Standards Institute (CLSI) and European Committee on Antimicrobial Susceptibility Testing (EUCAST) breakpoints and concordance of DD was compared with BMD.
