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 ...

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 ...

Antibiotic Resistance, Virulence Genes, and Molecular Diversity of Clinical Klebsiella pneumoniae Isolates from Patients of District Hospital in Central Poland

Pathogens
In hospital environments, pathogenic bacteria spread easily and acquire virulence and antibiotic resistance genes. The aim of the study was an evaluation of the genetic diversity of 109 K.

Characteristics of ventilator-associated pneumonia due to hypervirulent Klebsiella pneumoniae genotype in genetic background for the elderly in two tertiary hospitals in China

Antimicrobial Resistance and Infection Control, 2018
Background Aerobactin is a critical factor for the hypervirulent Klebsiella pneumoniae (hvKp), but data for the aerobactin-positive genotype of hvKp in elderly persons with ventilator-associated pneumonia (VAP) is limited. The purpose of this study is to

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.

Prevalence of virulence factors in Escherichia coli strains isolated from the genital tract of healthy cows Prevalência de fatores de virulência em cepas de Escherichia coli isoladas do trato genital de vacas saudáveis

Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2007
The prevalence of virulence genes expressing fimbriae, production of hemolysin, colicin and aerobactin, was determined in Escherichia coli isolates from healthy cow’s genital tract not showing clinical signs of infection.

Isolation, identification, and pathogenic potential of Bacillus cereus from diseased big‐belly seahorse Hippocampus abdominalis

Journal of the World Aquaculture Society, Volume 57, Issue 1, February 2026.
Abstract Members of Bacillus cereus have been documented as important bacterial pathogens in aquaculture. However, scarce information is available on B. cereus isolates as causal pathogens of big‐belly seahorses Hippocampus abdominalis. In the present study, a B. cereus isolate (SH1), recovered from a disease outbreak on a seahorse farm, was identified
