Disturbances in the geomagnetic field, water level and atmospheric pressure associated with Mw ≥ 6.6 earthquakes in the South Atlantic Ocean

Autor: María Alejandra Arecco, Patricia Alejandra Larocca, Fernando Ariel Oreiro, Mónica María Elisa Fiore, Lidia Ana Otero, María Florencia

Publikováno v: Geofísica Internacional, Vol 62, Iss 3, Pp 543-561 (2023)

This paper is aimed at studying disturbances in the earth’s geomagnetic field (GMF), water level (WL) and sea-level atmospheric pressure (AP) associated with Mw≥ 6.6 seismic events in the in the Scotia arch, in the South Atlantic. GMF records fro

Do Concurrent Peri-Implantitis and Periodontitis Share Their Microbiotas? A Pilot Study

Autor: Ana Parga, José Manuel Pose-Rodríguez, Andrea Muras, María Baus-Domínguez, Paz Otero-Casal, Marcos Luis Ortega-Quintana, Daniel Torres-Lagares, Ana Otero

Publikováno v: Dentistry Journal, Vol 12, Iss 4, p 113 (2024)

The microbial compositions from concurrent peri-implant and periodontal lesions were compared, since the results reported in the literature on the etiological relationship between these oral pathologies are contradictory. Microbial compositions from

Gram-negative quorum sensing signalling enhances biofilm formation and virulence traits in gram-positive pathogen Enterococcus faecalis

Autor: Ana Parga, Daniel Manoil, Malin Brundin, Ana Otero, Georgios N. Belibasakis

Publikováno v: Journal of Oral Microbiology, Vol 15, Iss 1 (2023)

ABSTRACTAcyl-homoserine lactones (AHLs) are typical quorum-sensing molecules of gram-negative bacteria. Recent evidence suggests that AHLs may also affect gram-positives, although knowledge of these interactions remains scarce. Here, we assessed the

Genomics, biofilm formation and infection of bladder epithelial cells in potentially uropathogenic Escherichia coli (UPEC) from animal sources and human urinary tract infections (UTIs) further support food-borne transmission

Autor: Vanesa García, Luz Lestón, Ana Parga, Isidro García-Meniño, Javier Fernández, Ana Otero, John E. Olsen, Ana Herrero-Fresno, Azucena Mora

Publikováno v: One Health, Vol 16, Iss , Pp 100558- (2023)

Escherichia coli is the main cause of urinary tract infections (UTI). While genomic comparison of specific clones recovered from animals, and human extraintestinal infections show high identity, studies demonstrating the uropathogenicity are lacking.

The quorum quenching enzyme Aii20J modifies in vitro periodontal biofilm formation

Autor: Ana Parga, Andrea Muras, Paz Otero-Casal, Alexandre Arredondo, Agnès Soler-Ollé, Gerard Àlvarez, Luis D. Alcaraz, Alex Mira, Vanessa Blanc, Ana Otero

Publikováno v: Frontiers in Cellular and Infection Microbiology, Vol 13 (2023)

IntroductionRecent studies have revealed the presence of N-acyl-homoserine lactones (AHLs) quorum sensing (QS) signals in the oral environment. Yet, their role in oral biofilm development remains scarcely investigated. The use of quorum quenching (QQ

New Preventive Strategy against Oral Biofilm Formation in Caries-Active Children: An In Vitro Study

Autor: Ana Parga, Sabela Balboa, Paz Otero-Casal, Ana Otero

Publikováno v: Antibiotics, Vol 12, Iss 8, p 1263 (2023)

Quorum quenching (QQ) is the inhibition of bacterial communication, i.e., quorum sensing (QS). QS is a key mechanism in regulating biofilm formation and phenotype in complex bacterial communities, such as those found within cariogenic biofilms. Where

A novel phenolic derivative inhibits AHL-dependent quorum sensing signaling in Pseudomonas aeruginosa

Autor: Giulia Bernabè, Giovanni Marzaro, Giuseppe Di Pietra, Ana Otero, Massimo Bellato, Anthony Pauletto, Melania Scarpa, Stefania Sut, Adriana Chilin, Stefano Dall’Acqua, Paola Brun, Ignazio Castagliuolo

Publikováno v: Frontiers in Pharmacology, Vol 13 (2022)

Increasing antibiotic resistance and the decline in the pharmaceutical industry’s investments have amplified the need for novel treatments for multidrug-resistant bacteria. Quorum sensing (QS) inhibitors reduce pathogens’ virulence without select
