AI Article Synopsis

  • Studies show that biofilms are a major cause of persistent infections linked to tissues and medical devices, highlighting the need for new treatment strategies.
  • Research is focusing on understanding biofilm formation, how they resist antibiotics, and how they evade the immune system, using lab and animal models.
  • There is a push for developing improved experimental models that better represent the conditions found in actual infections to enhance our understanding and treatment of chronic infections.

Article Abstract

Studies of biopsies from infectious sites, explanted tissue and medical devises have provided evidence that biofilms are the underlying cause of a variety of tissue-associated and implant-associated recalcitrant human infections. With a need for novel anti-biofilm treatment strategies, research in biofilm infection microbiology, biofilm formation mechanisms and biofilm-associated antimicrobial tolerance has become an important area in microbiology. Substantial knowledge about biofilm formation mechanisms, biofilm-associated antimicrobial tolerance and immune evasion mechanisms has been obtained through work with biofilms grown in in vitro experimental setups, and the relevance of this information in the context of chronic infections is being investigated by the use of animal models of infection. Because our current in vitro experimental setups and animal models have limitations, new advanced in vitro models developed with knowledge about the chemical landscape at infectious sites are needed.

Determining the optimal antibiotic duration for skin and soft tissue infections.

Curr Opin Infect Dis

January 2025

Department of Medicine, Clínica Rotger Quironsalud, Palma de Mallorca, Spain.

Purpose Of Review: Optimal duration of therapy in SSTIs - a heterogeneous group of infections - remains unknown. The advances in knowledge of antibiotic duration of treatment in selected SSTIs that can impact clinical practice and published in the last 18 months are reviewed.

Recent Findings: Recent evidence indicates that few patients receive guideline concordant empiric antibiotics and appropriate duration in the United States, although this likely can be extrapolated to other countries.

Antimicrobial prophylaxis is crucial in reducing surgical site infections (SSIs). First-generation cephalosporins are commonly first line, but issues arise when patients report a penicillin allergy. Although up to 10% of Americans report a penicillin allergy, up to 95% are not truly allergic.

ZmDREB1A controls plant immunity via regulating salicylic acid metabolism in maize.

Plant J

January 2025

National Key Laboratory of Crop improvement for Stress Tolerance and Production, College of Life Sciences, Northwest A&F University, Yangling, Shaanxi, 712100, China.

DREB1A, a pivotal transcription factor, has long been known to regulate plant abiotic stress tolerance. However, its role in plant biotic stress tolerance and the underlying mechanisms have remained a mystery. Our research reveals that the maize ZmDREB1A gene is up-regulated in maize seedlings when the plants are infected by Rhizoctonia solani (R.

The immune landscape of fetal chorionic villous tissue in term placenta.

Front Immunol

January 2025

Department of Microbiology, Immunology and Molecular Genetics, University of Kentucky, Lexington, KY, United States.

Introduction: The immune compartment within fetal chorionic villi is comprised of fetal Hofbauer cells (HBC) and invading placenta-associated maternal monocytes and macrophages (PAMM). Recent studies have characterized the transcriptional profile of the first trimester (T1) placenta; however, the phenotypic and functional diversity of chorionic villous immune cells at term (T3) remain poorly understood.

Methods: To address this knowledge gap, immune cells from human chorionic villous tissues obtained from full-term, uncomplicated pregnancies were deeply phenotyped using a combination of flow cytometry, single-cell RNA sequencing (scRNA-seq, CITE-seq) and chromatin accessibility profiling (snATAC-seq).
