Interplay of Diet, Heat Stress, and the Microbiome Shapes Health and Escape Behaviour in Amphibian Larvae

Environmental Microbiology, Volume 28, Issue 6, June 2026.
Diet and temperature jointly shape the gut microbiome and host performance in amphibian larvae. In a multifactorial experiment with Rana temporaria, diet quality, rearing temperature, and heatwave exposure altered microbial communities and predicted metabolic pathways, while host health remained largely stable, suggesting microbiome plasticity and ...

Aerobactin Synthesis Proteins as Antivirulence Targets in Hypervirulent Klebsiella pneumoniae [PDF]

ACS Infectious Diseases, 2019
Hypervirulent Klebsiella pneumoniae (hvKp) is an underrecognized pathotype of K. pneumoniae since the majority of cases have occurred in East Asia. However, hvKp is a public health threat due to its ability to infect healthy individuals, ongoing dissemination, and acquisition of resistance determinants.

Emergence and Genomic Characterization of a Hypervirulent Klebsiella pneumoniae Isolate From a New Clone in Brazil

Microbiology and Immunology, Volume 70, Issue 5, Page 261-267, May 2026.
ABSTRACT Hypervirulent Klebsiella pneumoniae (hvKp) has emerged globally as a major public health concern, often associated with severe community‐acquired and healthcare‐associated human infections. Despite alerts from PAHO/WHO on convergent hvKp strains with multidrug resistance in Latin America, comprehensive data from Brazil, the region's largest ...

Clinical and molecular characteristics of Klebsiella pneumoniae ventilator-associated pneumonia in mainland China

BMC Infectious Diseases, 2016
Background Klebsiella pneumoniae is a prominent nosocomial pathogen that accounts for up to 10 % of all hospital-acquired infections. It is a frequent cause of ventilator-associated pneumonia (VAP).

ColV plasmid-specific aerobactin synthesis by invasive strains of Escherichia coli [PDF]

Infection and Immunity, 1981
Certain strains of Escherichia coli associated with bacteremia of humans and domestic animals harbor plasmids that promote efficient iron uptake. The mechanism, which is an important component of the virulence of invasive strains, is independent of the enterobactin system for iron uptake.

Comparative Proteomic Profiling of Clinical Klebsiella pneumoniae Strains and the Corresponding Outer Membrane Vesicles

Journal of Extracellular Biology, Volume 5, Issue 4, April 2026.
ABSTRACT Klebsiella pneumoniae (K. pneumoniae) has become a global threat due to the convergence of carbapenem resistance and hypervirulence. Outer membrane vesicles (OMVs) play important roles in bacterial pathogenicity, yet their functional coordination with strains remains unclear.

A Case Series of Hypermucoid Klebsiella pneumoniae Liver Abscess in Caucasian Americans Without Travel History: An Epidemiologic Shift?

Clinical Case Reports, Volume 14, Issue 3, March 2026.
ABSTRACT Hypervirulent Klebsiella pneumoniae (hvKp) is an emerging cause of community‐acquired pyogenic liver abscess (PLA), classically described in East and Southeast Asia. We report two cases of hvKp‐associated PLA in Caucasian women of American origin with no history of international travel, animal exposure, or Asian food consumption. Both patients

Enterobacter Species: Opportunistic Human and Plant Pathogens With Plant‐Beneficial Traits

Molecular Plant Pathology, Volume 27, Issue 3, March 2026.
The pathogen profile on Enterobacter species synthesises current knowledge on host range, disease symptoms, plant‐beneficial traits and compares genomic features within the genus. ABSTRACT Enterobacter species occur across diverse habitats and are best known for causing opportunistic and nosocomial infections in humans.
