Analysis of the role of the LH92_11085 gene of a biofilm hyper-producing Acinetobacter baumannii strain on biofilm formation and attachment to eukaryotic cells
Acinetobacter baumannii is a nosocomial pathogen that has a considerable ability to survive in the hospital environment partly due to its capacity to form biofilms. The first step in the process of establishing an infection ... -
Anti-biofilm molecules targeting functional amyloids
The choice of an effective therapeutic strategy in the treatment of biofilm-related infections is a significant issue. Amyloids, which have been historically related to human diseases, are now considered to be prevailing ... -
Biofilm properties in relation to treatment outcome in patients with first-time periprosthetic hip or knee joint infection
Background: periprosthetic joint infections (PJI) are challenging complications following arthroplasty. Staphylococci are a frequent cause of PJI and known biofilm producers. Biofilm formation decreases antimicrobial ... -
Desarrollo y caracterización de recubrimientos biocidas basados en nanopartículas de plata depositadas mediante electrospraying
Las infecciones y las enfermedades infecciosas son una amenaza para la salud humana. La transmisión y propagación de microorganismos en instalaciones hospitalarias es un gran problema de salud a nivel mundial, agravado ... -
Functional analysis of intergenic regulatory regions of genes encoding surface adhesins in Staphylococcus aureus isolates from periprosthetic joint infections
Staphylococcus aureus is a leading cause of prosthetic joint infections (PJI). Surface adhesins play an important role in the primary attachment to plasma proteins that coat the surface of prosthetic devices after ... -
Genomics of Staphylococcus aureus and Staphylococcus epidermidis from periprosthetic joint infections and correlation to clinical outcome
The approach of sequencing or genotyping to characterize the pathogenic potential of staphylococci from orthopedic device-related infection (ODRI) has been applied in recent studies. These studies described the genomic ... -
Insights into c-di-GMP signaling and the PGA exopolysaccharide biological functions using Salmonella as a model organism
Salmonella es un patógeno alimentario de gran relevancia clínica capaz de adherirse a superficies y formar comunidades bacterianas embebidas en una matriz que ellas mismas producen denominadas biofilms. Esta matriz ... -
Papel de los sistemas de dos componentes de Staphylococcus aureus en la susceptibilidad a complestatina y corbomicina y en la regulación génica en ausencia de fosforilación
(2022) Tesis doctoral / Doktoretza tesiaStaphylococcus aureus es una bacteria versátil que se puede encontrar estableciendo una relación comensal en la piel de, aproximadamente, el 30% de la población sin causar ningún problema. Sin embargo, cuando ésta atraviesa ... -
Role of sodium salicylate in Staphylococcus aureus quorum sensing, virulence, biofilm formation and antimicrobial susceptibility
The widespread threat of antibiotic resistance requires new treatment options. Disrupting bacterial communication, quorum sensing (QS), has the potential to reduce pathogenesis by decreasing bacterial virulence. The aim ... -
Salmonella biofilm development depends on the phosphorylation status of RcsB
The Rcs phosphorelay pathway is a complex signaling pathway involved in the regulation of many cell surface structures in enteric bacteria. In response to environmental stimuli, the sensor histidine kinase (RcsC) ... -
A systematic evaluation of the two-component systems network reveals that ArlRS is a key regulator of catheter colonization by Staphylococcus aureus
Two-component systems (TCS) are modular signal transduction pathways that allow cells to adapt to prevailing environmental conditions by modifying cellular physiology. Staphylococcus aureus has 16 TCSs to adapt to the ...
