Antimicrobial Susceptibility and Virulence of mcr-1-Positive Enterobacteriaceae in China, a Multicenter Longitudinal Epidemiological Study

In conclusion, the prevalence of MPE in IAI, UTI, and LRTI were low in China, and no clonal transmission was identified in our study. Most MPE isolates exhibited low-level colistin resistance. However, our study indicated that MPE isolates always carried a variety of drug resistance and virulence genes, which should be paid more attention.

Conclusion Bacteria traditionally considered to be more pathogenic outside of pregnancy do not progress to pyelonephritis at higher rates than E. coli in pregnancy, and are associated with similar pyelonephritis-related morbidity. Larger studies are needed to confirm these findings.

In conclusion, the addition of 38 ExPEC-associated genes and the associated alleles to the E. coli VirulenceFinder database allows for a more complete characterization of E. coli isolates based on WGS data, which has become increasingly important considering the plasticity of the E. coli genome.

by Nikos Fatsis-Kavalopoulos, Roderich Roemhild, Po-Cheng Tang, Johan Kreuger, Dan I. Andersson Antibiotic combination therapies are important for the efficient treatment of many types of infections, including those caused by antibiotic-resistant pathogens. Combination treatment strategies are typically used under the assumption that synergies are conserved across species and strains, even t hough recent results show that the combined treatment effect is determined by specific drug–strain interactions that can vary extensively and unpredictably, both between and within bacterial species. To address this problem, we ...

Authors: Wu S, Rajeshkumar S, Madasamy M, Mahendran V Abstract The green approachable of metal nanoparticles is treated to be an eco-friendly path and cost-effectiveness. In this present study, nano copper was synthesized profitably by Cissus vitiginea. The synthesized nano copper was used to evaluate the antioxidant and antibacterial activity against urinary tract infections pathogens. The resulting constructed nanoparticles were characterized by using ultraviolet spectroscopy absorbance around 370 nm. Scanning electron microscopy results showed the distribution of nanoparticles and particles sizes are foun...

ute;nchez Á, Rodríguez-Antolín A Abstract INTRODUCTION AND OBJECTIVE: Radical cystectomy is a complex surgery with a high rate of complications including infections, which lead to increased morbidity and mortality, longer hospital stay and higher costs. The aim of this work is to evaluate health care-associated infections (HAIs) in these patients, as well as associated microorganisms, antibiotic resistance profiles and risk factors. MATERIAL AND METHODS: Prospective study from 2012 to 2017. Epidemiologic variables, comorbidities and surgical variables are collected. The microorganisms inv...

Resistance to antimicrobial compounds in E. coli strains is increasing. Integrons are mobile genetic elements that lead to the spread and transfer of antibiotic resistance genes in bacteria. The aim of the present study was to determine the frequency of class 1 and 2 integrons as well as the antimicrobial resistance in E.coli strains isolated from urinary tract infections (UTIs). A total of 100 clinical isolates of uropathogenic E. coli (UPEC) were collected from patients having UTIs. These strains were identified using biochemical tests. The antibiotic susceptibility patterns of the isolated bacteria were determined in ac...

CONCLUSIONS: The hospital incidence of neonatal meningitis was 1.4 per 1000 live births, being ten times higher in preterm infants. Breathing difficulty was the most frequent symptom in the early stage, while fever and irritability in the late stage. CSF showed pleocytosis without predominance of PMN. The most frequent germs were Escherichia coli and Listeria monocytogenes. Ventriculitis and hydrocephalus were the most common neurological complications. PMID: 32876208 [PubMed - in process]

In this study, the genomes of 66 E. coli isolates from adult female bladders were sequenced. These isolates were collected from four cohorts, including women: (1) without lower urinary tract symptoms, (2) overactive bladder symptoms, (3) urgency urinary incontinence, and (4) a clinical diagnosis of UTI. Comparative genomic analyses were conducted, including core and accessory genome analyses, virulence and motility gene analyses, and antibiotic resistance prediction and testing. We found that the genomic content of these 66 E. coli isolates does not correspond with the participant’s symptom status. We thus looked bey...

Abstract During their lifetime almost half of women will experience a symptomatic urinary tract infection (UTI) with a further half experiencing a relapse within six months.  Currently UTIs are treated with antibiotics, but increasing antibiotic resistance rates highlight the need for new treatments. Uropathogenic  Escherichia coli  (UPEC) is responsible for the majority of symptomatic UTI cases and thus has become a key pathological target. Adhesion of type one pilus subunit FimH at the surface of UPEC strains to mannose-saturated oligosaccharides located on the urothelium is critical to ...
