Optimization of an Experimental Vaccine To Prevent Escherichia coli Urinary Tract Infection

mBio, 2020
Urinary tract infections (UTI) affect half of all women at least once during their lifetime. The rise in the numbers of extended-spectrum beta-lactamase-producing strains and the potential for carbapenem resistance within uropathogenic Escherichia coli ...

The Drawback of Optimizing Air Cleaner Filters for the Adsorption of Formaldehyde

Atmosphere
Air cleaners with activated carbon (AC) filters for the adsorption of gaseous pollutants are often used to improve indoor air quality. As formaldehyde is a common and health-relevant indoor air pollutant, many testing standards for air cleaners, such as ...

Expression of Genes Located on the Incompatibility Group FIB Plasmids at Transcription and Protein Levels in Iron-Modified Growth Conditions

Frontiers in Microbiology, 2021
Salmonella enterica strains often harbor plasmids representing several incompatibility groups (Inc) including IncFIB, which have been previously associated with carrying antimicrobial resistance and virulence associated genes.

Electret Filters—From the Influence of Discharging Methods to Optimization Potential

Atmosphere, 2021
Electret filters are electrostatically charged nonwovens which are commonly used in aerosol filtration to remove fine particles from gases. It is known that the charge and thus also the filtration efficiency can degrade over time.

Magnetic Lateral Flow Immunoassays

Diagnostics, 2020
A new generation of magnetic lateral flow immunoassays is emerging as powerful tool for diagnostics. They rely on the use of magnetic nanoparticles (MNP) as detecting label, replacing conventional gold or latex beads. MNPs can be sensed and quantified by

Magnetic Nanoclusters Increase the Sensitivity of Lateral Flow Immunoassays for Protein Detection: Application to Pneumolysin as a Biomarker for Streptococcus pneumoniae

Nanomaterials, 2022
Lateral flow immunoassays for detecting biomarkers in body fluids are simple, quick, inexpensive point-of-care tests widely used in disease surveillance, such as during the coronavirus disease 2019 (COVID-19) pandemic.

Antibiotic resistance is linked to carriage of papC and iutA virulence genes and phylogenetic group D background in commensal and uropathogenic Escherichia coli from infants and young children [PDF]

European Journal of Clinical Microbiology & Infectious Diseases, 2016
P fimbriae, enabling adherence to colonic and urinary epithelium, and aerobactin, an iron sequestering system, are both colonization factors in the human colon and virulence factors for urinary tract infection. The colonic microbiota is suggested to be a site suitable for the transfer of antibiotic resistance genes.

Longitudinal Molecular Epidemiology and Genomic Surveillance of Carbapenem‐Resistant Klebsiella pneumoniae in the Gut of Healthy Individuals in China

MedComm, Volume 7, Issue 8, August 2026.
Using 16,040 stool samples from healthy individuals across 30 Chinese provinces (2016–2024), we performed longitudinal genomic surveillance of carbapenem‑resistant Klebsiella pneumoniae (CRKP) colonizing the gut. We reveal rising community CRKP prevalence, especially in southern China, a shift from blaKPC‐2 to plasmid‑borne blaNDM‐5 on IncHI2/IncHI2A ...

Hypervirulent Klebsiella pneumoniae Infections: A Systematic Review of Clinical, Microbiological, and Outcome Data From Reported Cases

MicrobiologyOpen, Volume 15, Issue 3, June 2026.
Distribution of organ involvement in reported hypervirulent Klebsiella pneumoniae cases. Studies restricted to isolated liver abscess cases were excluded. Percentages represent the proportion of cases with documented involvement of each anatomical site among cases with available data.
