Health Tip: Help Prevent E coli Infection

-- Escherichia coli(E. coli) is a bacterium that's found in the environment, foods and intestines of people and animals. Many strains are harmless, but some can make you very sick, causing diarrhea, urinary tract infection, respiratory illness and...

Publication date: April 2019Source: Molecular Immunology, Volume 108Author(s): Mohammad Reza Asadi Karam, Mehri Habibi, Saeid BouzariAbstractUrinary tract infections (UTIs) are recognized as one of the most common infectious diseases in the world that can be divided to different types. Uropathogenic Escherichia coli (UPEC) strains are the most prevalent causative agent of UTIs that applied different virulence factors such as fimbriae, capsule, iron scavenger receptors, flagella, toxins, and lipopolysaccharide for their pathogenicity in the urinary tract. Despite the high pathogenicity of UPEC strains, host utilizes differe...

(Technical University of Denmark) Scientists from the Novo Nordisk Foundation Center for Biosustainability have discovered that a combination of two common antibiotics is able to eliminate multi-drug resistant E. coli causing urinary tract infections. This combination treatment could become an effective measure against clinically relevant antibiotic resistant urinary tract infections.

Conclusions: Bacterial UTI persists as one of the most common infections affecting all age groups and both genders. As in other countries, E. coli ranks first in Mexico, with 67.28%, and nearly 50% of the strains produce ESBL. PMID: 30768071 [PubMed - in process]

CONCLUSIONS: Continuous antimicrobial resistance surveillance from the SMART study reveals overall maintenance of ESBL-producers in Spain, although with higher presence in isolates from UTIs than from IAIs. Moreover, ertapenem activity was high in E. coli irrespective of ESBL production but decreased in K. pneumoniae, particularly among ESBL-producers. PMID: 30761824 [PubMed - as supplied by publisher]

Abstract Rapid changes in the number and flow cytometric behaviour of cells of E. coli taken from a stationary phase and inoculated into rich medium.Cells of E. coli were grown in LB medium, taken from a stationary phase of 2-4 h, and re-inoculated into fresh media at a concentration (105 ml-1 or lower) characteristic of bacteriuria. Flow cytometry was used to assess how quickly we could detect changes in cell size, number, membrane energization (using a carbocyanine dye) and DNA distribution. It transpired that while the lag phase observable macroscopically via bulk OD measurements could be as long ...

In conclusion, we could demonstrate an extensive variation of EPE strain types, plasmid composition, rearrangements and horizontal gene transfer of genetic material illustrating the high dynamics nature and interactive environment of the gut microbiota during post UTI carriage.

This study mainly focuses on synthesizing eco-friendly AgNPs from coral-associated bacteria. A total of 57 coral bacterial isolates were screened for synthesizing AgNPs and the isolate MGL- D10 was selected for synthesizing AgNPs. The isolate MGL- D10 was identified as Alcaligenes sp. using 16srRNA sequencing. The synthesized AgNPs MGL- D10 was then characterized using UV–Vis spectroscopy, FTIR, and X-ray diffraction (XRD) analysis. Further, the morphology and the size of the synthesized AgNPs was observed through Atomic Force Microscopy (AFM) Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (T...

Abstract Iron is a critical nutrient required by hosts and pathogens. Uropathogenic Escherichia coli (UPEC), the principal causative agent of urinary tract infections (UTIs), chelate iron for their survival and persistence. Here, we demonstrate that dietary modulation of iron availability limits UPEC burden in a mouse model of UTI. Mice on a low iron diet exhibit reduced systemic and bladder mucosal iron availability, harbor significantly lower bacterial burden, concomitant with dampened inflammation. Hepcidin is a master regulator of iron that controls iron-dependent UPEC intracellular growth. Hepcidin deficient ...

Gentilini, José Di Conza, Gabriel GutkindAbstractExtended-spectrum β-lactamase (ESBL), plasmid-mediated AmpC (pAmpC) and MCR-1 phosphoethanolamine transferase enzymes have been pointed out as the main plasmid-mediated mechanisms of resistance to third generation cephalosporins (TGC) and colistin, respectively, and are currently considered a major concern both in human and veterinary medicine....

A 52yo postmenopausal woman with chronic pelvic pain and a history of interstitial cystitis underwent total laparoscopic hysterectomy, bilateral salpingectomy, and cystoscopy. Two months before surgery, the patient had a cystoscopy with urogynecology revealing a normal bladder and urethra. Two weeks prior to hysterectomy, she was treated for an Escherichia coli urinary tract infection (UTI) with cephalexin. After an uncomplicated hysterectomy (without evidence of endometriosis), routine cystoscopy was performed which revealed the above findings (figure 1).
