Invasive giant river prawns as opportunistic, generalist predators in the Amazon Delta: Insights from metabarcoding

Ecosphere, Volume 16, Issue 11, November 2025.
Abstract Invasive species alter habitats and biological communities. The giant river prawn Macrobrachium rosenbergii (de Man 1879) was introduced to Brazil for aquaculture, and invasive populations have established in the Amazon Delta region where they are believed to pose a risk to the native aquatic fauna.

D-mannose: a promising support for acute urinary tract infections in women. A pilot study [PDF]

, 2016
Urinary tract infections still represent a significant bother for women and result in high costs to the health system. D-mannose is a simple sugar; it seems able to hinder bacteria adhesion to the urothelium.

Uropathogenic Escherichia coli superinfection enhances the severity of mouse bladder infection [PDF]

, 2015
Urinary tract infections (UTIs) afflict over 9 million women in America every year, often necessitating long-term prophylactic antibiotics. One risk factor for UTI is frequent sexual intercourse, which dramatically increases the risk of UTI.

Type 1 fimbriae are important factors limiting the dissemination and colonization of mice by Salmonella Enteritidis and contribute to the induction of intestinal inflammation during Salmonella invasion

Frontiers in Microbiology, 2015
We have recently shown that S. Gallinarum type 1 fimbriae with endogenous mannose-resistant (MR) variant of the FimH protein increase systemic dissemination of S. Gallinarum and colonization of internal organs in comparison to the S.

Genomic Characterization of Pan‐Drug Resistant Klebsiella pneumoniae KPNW Isolated From UTI Patient in Bangladesh

MicrobiologyOpen, Volume 14, Issue 5, October 2025.
Klebsiella pneumoniae isolate KPNW showed resistance to all clinically relevant antibiotics. Upon whole genome sequencing and characterization, we detected a large number of antimicrobial resistance genes, resistance‐associated point mutations, virulence determinants, heavy metal resistance genes, and mobile genetic elements in errorits genome ...

Comparative proteomics of uropathogenic Escherichia coli during growth in human urine identify UCA-like (UCL) fimbriae as an adherence factor involved in biofilm formation and binding to uroepithelial cells [PDF]

, 2015
Uropathogenic Escherichia coli (UPEC) are the primary cause of urinary tract infection (UTI) in humans. For the successful colonisation of the human urinary tract, UPEC employ a diverse collection of secreted or surface-exposed virulence factors ...

The molecular characterisation of Escherichia coli K1 isolated from neonatal nasogastric feeding tubes [PDF]

, 2015
Background: The most common cause of Gram-negative bacterial neonatal meningitis is E. coli K1. It has a mortality rate of 10–15%, and neurological sequelae in 30– 50% of cases.

High Rates of Antimicrobial Resistance and Emergence of High‐Risk Clones in Community‐Acquired Uropathogenic Escherichia coli

MicrobiologyOpen, Volume 14, Issue 5, October 2025.
A total of 98 E. coli isolates from community‐acquired UTIs were analyzed, revealing high resistance rates to trimethoprim‐sulfamethoxazole and fluoroquinolones. Phylogenetic group B2 was the most prevalent and associated with increased virulence, while ST1193 emerged as the dominant MDR clone.
