Indole‐Acetic Acid Impairs Pseudomonas aeruginosa Virulence and Alters Lung Infection in Mice

MicrobiologyOpen, Volume 14, Issue 6, December 2025.
Screening for anti‐virulence activity exerted by tryptophan catabolites on laboratory and clinical strains of Pseudomonas aeruginosa showed that Indoleacetic acid (IAA) inhibits motility and pigment production, downregulates PQS gene expression, while increases oxidative stress sensitivity.

Microbial biomass and activity in litter during the initial development of pure and mixed plantations of Eucalyptus grandis and Acacia mangium

Revista Brasileira de Ciência do Solo, 2013
Studies on microbial activity and biomass in forestry plantations often overlook the role of litter, typically focusing instead on soil nutrient contents to explain plant and microorganism development. However, since the litter is a significant source of

Estudo imagético sobre microrganismos na web

Amazônia: Revista de Educação em Ciências e Matemáticas, 2020
O objetivo desta pesquisa foi identificar concepções que perpassam as imagens de microrganismos, disponibilizadas on-line, avaliando se estas contribuem para a construção adequada, reducionista ou equivocada do ensino em microbiologia. O estudo, de caráter qualitativo, orientou-se pelo enfoque exploratório, utilizando como metodologia a construção de ...

Microbial drivers of root plasticity

New Phytologist, Volume 248, Issue 1, Page 52-67, October 2025.
Summary Soils are highly heterogeneous and dynamic systems, experiencing a constant flow of plant root exudates and moisture fluctuations that affect nutrient distribution, soil physicochemical properties, and microbial metabolisms. Plant roots adjust their development within the soil matrix (growth, branching, root angle, and anatomical features) by ...

Proteins and peptides as antigen candidates for the immunodiagnosis of hepatitis D

Amino Acids
Designing innovative, accurate, universal, and accessible diagnostic tests is mandatory to improve screening, prevention, and management of hepatitis D (HD), especially in endemic areas with poor infrastructure and restricted access to public health care.

Carbapenem-resistant hypervirulent P. aeruginosa coexpressing exoS/exoU in Brazil

Journal of Global Antimicrobial Resistance
Background: Pseudomonas aeruginosa is a ubiquitous organism with high clinical impact due to its intrinsic resistance to many antimicrobial drugs and ability to acquire antibiotic resistance and virulence genes.

Antibiotic‐Induced Dysbiosis of the Gut Microbiota Shifts Host Tryptophan Metabolism and Increases the Susceptibility of Mice to Pulmonary Infection With Pseudomonas aeruginosa

Immunology, Volume 175, Issue 4, Page 453-466, August 2025.
Antibiotic‐induced dysbiosis of the gut microbiota shifts host tryptophan metabolism and impairs the innate immune response during Pseudomonas aeruginosa pulmonary infection. (A) Eubiosis: During eubiosis, the intestinal microbiota metabolises tryptophan into indole metabolites, which keeps tryptophan levels within normal serum concentrations. However,

Plant Antimicrobial Peptides and Their Main Families and Roles: A Review of the Literature

Current Issues in Molecular Biology
Antimicrobial peptides (AMPs) are constituent molecules of the innate defense system and are naturally produced by all organisms. AMPs are characterized by a relatively low molecular weight (less than 10 kDa) and a variable number of cysteine residues ...

Land Use Change Consistently Reduces α‐ But Not β‐ and γ‐Diversity of Bees

Global Change Biology, Volume 31, Issue 1, January 2025.
We analyzed a global dataset of 3117 bee assemblages across 157 studies to assess how bee diversity varies among natural, agricultural, and urban habitats. We measured diversity using both the number of bee taxa (taxonomic diversity) and their evolutionary relationships (phylogenetic diversity).
