Scaffolds grafting combined with local delivery of antibiotics at the injury site may promote bone regeneration along prevention infections. In this work, a processing strategy combining 3D-printing polysaccharide-based inks supercritical (sc)CO2 technology was employed to manufacture drug-loaded, nanostructured, and personalized-to-patient aerogels for first time. Methylcellulose (MC) as graft matrix endowed nanohydroxyapatite (nHA) confer bioactivity required in tissue engineering (BTE)....
The biochemical, serological and molecular characteristics of a group 21 Edwardsiella tarda strains isolated from turbot, Psetta maxima, in two different areas Europe were analysed compared with total 13 this bacterial species geographical host origins. All the turbot isolates biochemically identical to E. included as reference. use techniques including microagglutination, dot blot Western lipopolysaccharides allowed us determine that all constitute an homogeneous distinctive group. Genetic...
Tenacibaculum maritimum (formerly Flexibacter maritimus) is a filamentous, biofilm-forming member of the Cytophaga-Flavobacterium-Bacteroides group (or Bacteroidetes), which causes widely distributed marine fish disease tenacibaculosis. A search for N-acylhomoserine lactones (AHLs) quorum-sensing (QS) signals in culture media nine representative strains this species using different biosensor revealed presence short-type AHL activity all them. N-butyryl-L-homoserine lactone (C4-HSL) was...
We compared Pasteurella piscicida strains isolated from different fish species in several European countries with Japan and the United States. The taxonomic analysis revealed that, regardless of geographic origin source isolation, all exhibited same biochemical physiological characteristics. Serological assays rabbit antisera demonstrated a high level antigenic similarity among strains, cross-agglutination titers 20,480 to 40,960. This serological homogeneity was supported by...

This study was designed to assess whether hydrogel contact lens (CL) surface hydrophobicity and roughness affect Staphylococcus epidermidis adhesion.Bacterial adhesion experiments were performed on two unworn silicone three conventional CLs using the S.epidermidis strain CECT 4184. Microbial colonization assessed by conducting counts expressed as colony-forming units. CL determined through water angle measurements parameters such mean (Ra), kurtosis (Rku), skewness (Rsk) atomic force...
Tenacibaculum maritimum, the etiological agent of tenacibaculosis in marine fish, constitutively secretes extracellular products (ECPs) which protein content has not been yet comprehensively studied. In this work, prevalence proteolytic and lipolytic activities related to virulence was analyzed 64 T. maritimum strains belonging O1-O4 serotypes. The results showed existence a great intra-specific heterogeneity enzymatic capacity, particularly within serotype O4. Thus, secretome strain...
Prolonged and excessive use of biocides during the coronavirus disease era calls for incorporating new antiviral polymers that enhance surface design functionality existing potential future pandemics. Herein, we investigated previously unexplored polyamines with nucleophilic biguanide, guanidine, hydantoin groups all can be halogenated leading to high contents oxidizing halogen enables enhancement biocidal activity. Primary amino used attach poly(N-vinylguanidine) (PVG)...
This work aimed to explore an alternative the use of antibiotics for prevention and treatment wounds infection caused by two common bacterial pathogens Staphylococcus aureus Pseudomonas aeruginosa. For this purpose, three different essential oil components (EOCs), namely carvacrol, citronellol cinnamic acid, were loaded into electrospun fibers poly-ε-caprolactone (PCL) aided alpha-cyclodextrin (αCD) hydroxypropyl-β-cyclodextrin (HPβCD). Electrospun-fibers prepared with each EOC their...
Glioblastoma (GB) is a malignant brain tumor with low survival rates and high recurrence ratio due to limited therapeutic arsenal. The repurposed drug disulfiram (DSF), approved for alcoholism treatment, shows promising anticancer antimicrobial activity, but its poor biopharmaceutical profile hinders clinical use. This work aimed develop DSF-loaded silk fibroin (SF) electrospun fibers controlled release in the postsurgical resection cavity. Incorporating hydroxypropyl-β-cyclodextrin (HPβCD),...
The stability of Pasteurella piscicida strains in seawater and sediment microcosms at different temperatures (6 20 degrees C) was investigated during a 1-month period. Three P. showed similar survival kinetics. By standard plate count method they survived water for only 6 to 12 days, depending on the strain type microcosm. During this starvation period, metabolic activity cells reduced by more than 80%. Culturable each persisted better water, as well C compared C. However, all microcosms,...
We evaluated the iron uptake mechanisms in Pasteurella piscicida strains as well effect of overload on virulence these for fish. With this aim, capacity to obtain from transferrin and heme compounds their ability overcome inhibitory activity fish serum was analyzed. All P. grew presence chelator ethylene-diamine-di (O-hydroxyphenyl acetic acid) or human transferrin, which used by a siderophore-mediated mechanism. The chemical tests cross-feeding assays showed that produced siderophore...
SUMMARY: The pathobiological activities in vivo and vitro of live cells extracellular products (ECP) eleven Pasteurella piscicida strains different origin were examined. Infectivity trials showed that P. did not possess strict host specificity since the majority isolates virulent for gilthead seabream, rainbow trout turbot, with LD50 values ranging between 103 106 cells. However, none tested pathogenic mice (LD50 > 108 cells). In addition, ECP strongly toxic fish from 1.0 to 4.6 μg protein...
The turbot (Scophthalmus maximus; Scophthalmidae; Pleuronectiformes) is a flatfish species of great relevance for marine aquaculture in Europe. In contrast to other cultured flatfish, very few genomic resources are available this species. Aeromonas salmonicida and Philasterides dicentrarchi two pathogens that affect culture causing serious economic losses the industry. Little known about molecular mechanisms disease resistance host-pathogen interactions work, thousands ESTs functional...
