Combined Dietary Administration of and Ethanol-Inactivated Modulates Intestinal Microbiota and Gene Expression in .

The use of functional feeds in aquaculture is currently increasing. This study aimed to assess the combined impact of dietary green microalgae and ethanol-inactivated DCF12.2 (CVP diet) on thick-lipped grey mullet () juvenile fish.

Unusual Surge of Acute Hepatitis A Cases in 2016 and 2017 in Malaga, Southern Spain: Characterization and Relationship with Other Concurrent European Outbreaks.

We aimed to describe the Hepatitis A virus (HAV) cases that arose in Malaga (Spain) in 2016 and 2017 when the European Centre for Disease Prevention and Control (ECDC) reported several outbreaks among men who have sex with men (MSM). Therefore, we conducted a retrospective study gathering demographic, clinical, and immunological data from the acute HAV patients attending our hospital between March 2016 and December 2017. Additionally, VP1/P2A region was amplified from serum samples, sequenced, and genotyped.

In Vitro and In Vivo Effects of Ulvan Polysaccharides from .

One of the main bioactive compounds of interest from the species is the sulfated polysaccharide ulvan, which has recently attracted attention for its anticancer properties. This study investigated the cytotoxic activity of ulvan polysaccharides obtained from in the following scenarios: (i) in vitro against healthy and carcinogenic cell lines (1064sk (human fibroblasts), HACAT (immortalized human keratinocytes), U-937 (a human leukemia cell line), G-361 (a human malignant melanoma), and HCT-116 (a colon cancer cell line)) and (ii) in vivo against zebrafish embryos. Ulvan exhibited cytotoxic effects on the three human cancer cell lines tested.

Zoonotic Parasites in Playgrounds in Southern Spain: A One Health Approach.

Zoonotic parasitic diseases are considered a global threat to public health. In this sense, canines and felines may be infected by different cosmopolitan parasites, with playgrounds serving as an important focus of infection for humans, as well as domestic or wild animals. Knowledge of the epidemiological situation of parasites in animal reservoirs integrated into the environment, identifying the spread pathways, is a key element for an effective response to this threat.

Antioxidant, Immunomodulatory and Potential Anticancer Capacity of Polysaccharides (Glucans) from Euglena gracilis G.A. Klebs.

The present study was carried out to determine the bioactivity of polysaccharides extracted from (EgPs). These were characterized by FT-IR and GC-MS. Cytotoxicity analyses (MTT) were performed on healthy human gingival fibroblast cell lines (HGF-1), obtaining an IC of 228.

Vaccination of Gilthead Seabream After Continuous Xenoestrogen Oral Exposure Enhances the Gut Endobolome and Immune Status GPER1.

In fish culture settings, the exogenous input of steroids is a matter of concern. Recently, we unveiled that in the gilthead seabream (), the G protein-coupled estrogen receptor agonist G-1 (G1) and the endocrine disruptor 17α-ethinylestradiol (EE) are potent modulators in polyreactive antibody production. However, the integral role of the microbiota upon immunity and antibody processing in response to the effect of EE remains largely unexplored.

Cultivated and Wild Juvenile Thick-Lipped Grey Mullet, : A Comparison from a Nutritional Point of View.

The thick-lipped grey mullet () is a nominee fish species for aquaculture diversification in Spain because it is an omnivore and euryhaline species, but limited knowledge about the nutritional attributes of this species is available. This study aimed to characterize the chemical composition of wild and cultured fish. The muscle proximate composition, and fatty acid and amino acid profiles were assessed.

TarSynFlow, a workflow for bacterial genome comparisons that revealed genes putatively involved in the probiotic character of strain Pdp11.

Probiotic microorganisms are of great interest in clinical, livestock and aquaculture. Knowledge of the genomic basis of probiotic characteristics can be a useful tool to understand why some strains can be pathogenic while others are probiotic in the same species. An automatized workflow called TarSynFlow (Targeted Synteny Workflow) has been then developed to compare finished or draft bacterial genomes based on a set of proteins.

Accumulation and Depuration of Pathogenic and Indicator Microorganisms by the bivalve mollusc, Chamelea gallina L, Under Controlled Laboratory Conditions.

The comparative accumulation and depuration processes for several microorganisms ( Escherichia coli , Salmonella typhimurium , Vibrio parahaemolyticus , Aeromonas hydrophila , Streptococcus faecalis , Staphylococcus aureus , and MS-2 coliphage) by the striped venus, Chamelea gallina , under controlled laboratory conditions were studied. Microorganisms accumulated rapidly in bivalves during the first 6 h, with accumulation rates between 3.2 to 360.
