Vibrio vulnificus biotype 2, pathogenic for eels, is also an opportunistic pathogen for humans

1996

We report that the eel pathogen Vibrio vulnificus biotype 2 is also an opportunistic pathogen for humans. Results from a detailed comparative study using reference strains of both biotypes revealed that the clinical strain ATCC 33817, originally isolated from a human leg wound and classified as V. vulnificus (no reference on its biotype is noted), belongs to biotype 2 of the species. As a biotype 2 strain, it is negative for indole and pathogenic for eels and mice, harbors two plasmids of high MrS, and belongs to serogroup E, recently proposed as characteristic of biotype 2 strains. In consequence, appropriate measures must be taken by consumers, particularly by those running a health risk,…

Supplementation with cactus pear (Opuntia ficus-indica) fruit decreases oxidative stress in healthy humans: a comparative study with vitamin C.

2004

Background: Cactus pear (Opuntia ficus-indica) fruit contains vitamin C and characteristic betalain pigments, the radical-scavenging properties and antioxidant activities of which have been shown in vitro. Objective: We investigated the effects of short-term supplementation with cactus pear fruit compared with vitamin C alone on total-body oxidative status in healthy humans. Design: In a randomized, crossover, double-treatment study, 18 healthy volunteers received either 250 g fresh fruit pulp or 75 mg vitamin C twice daily for 2 wk, with a 6-wk washout period between the treatments. Before (baseline) and after each treatment, 8-epiprostaglandin F2α (8-epi-PGF2α) and malondialdehyde in plas…

Draft Genome Sequence of Environmental Bacterium Vibrio vulnificus CladeA-yb158

2015

ABSTRACT We report the genome sequence of the environmental Vibrio vulnificus biotype 1_cladeA. This draft genome of the CladeA-yb158 strain, isolated in Israel, represents this newly emerged clonal group that contains both clinical and environmental strains.

Eelness: Transcriptomic analysis of Vibrio-induced immune response in European eel

2014

La malaltia és l’alteració de l’estat fisiològic d’un individu, dificultant les seves funcions vitals i fins i tot, comportant a la mort. Tots els éssers vius poden contraure malaltia, aquesta, és majoritàriament provocada per microorganismes patògens, incloent bacteris, virus, protozous i fongs. Al llarg de la infecció, la relació hoste-patògen és clau. Per una banda, l’hoste ha de comptar amb un sistema immunitari eficaç, capaç de combatre l’infecció, mantenint les funcions vitals i per tant, evitant la mort. Per l’altre banda, el patogen desenvolupa una sèrie de factors per tal de aconseguir una invasió exitosa i per tant, provocant infecció. L’objectiu principal d’aquest tesi és l’estud…

Vibriosis in aquaculture. 16th EAFP Conference, Tampere, Finland, 4th September 2013

2014

Aquaculture in brackish and marine water is growing worldwide (FAO, 2014), including new cultured species. Various Vibrio infections occur, and cause significant problems, in fish, crustacean and shellfish (Austin & Austin, 2007. Vibrio anguillarum, V. salmonicida, V. ordalii and V. vulnificus are among the pathogens that lead to the biggest losses in aquaculture all over the world (Toranzo et al. 2005, Sandlund et al., 2010; Sitjà-Bobadilla et al. 2014).

Species-Specific Antioxidant Power and Bioactive Properties of the Extracts Obtained from Wild Mediterranean Calendula Spp. (Asteraceae)

2019

In this study we focused on four taxa of the genus Calendula (C. maritima, C. suffruticosa subsp. fulgida, C. arvensis, and the hybrid between the first two ones), collected in Mediterranean area (Sicily). Six extracts for each species were obtained using solvents with increasing polarity (hexane, ethanol 80%, acetone 70%, and water) and through extraction by supercritical fluids (SFE). It has been observed that the solvent with the highest extraction efficiency was ethanol 80% for all species. However, SFE extracts showed high antioxidant activity comparable to the ethanol 80% extract (polyphenol, DPPH, and reducing power method). These findings were confirmed by in vitro analysis (MTT ass…

Development of the adhesive pad on climbing fig (Ficus pumila) stems from clusters of adventitious roots

2003

Vines have different climbing strategies; one type, called clinging vines, has developed a specialized structure, the adhesive pad that secretes a sticky substance that adheres to almost any substrate. In this study on the climbing fig, Ficus pumila L., we report on the developmental anatomy of clusters of adventitious roots that become transformed into this unique structure. Clustered adventitious roots in F. pumila are initiated in pairs on either side of a vascular bundle at the 2nd to 3rd internodes of young stems. After emergence through the cortex and epidermis, root hairs form, which secrete a substance that stains positively for polysaccharide and protein. The adventitious roots and…
