Abstract

Simple Summary: The harsh aquatic environment makes the use of dietary probiotics not cost-effective and with low efficacy due to their inability to reach the gut. Therefore, supporting the growth of commensal probiotic bacteria, in aquatic animals, represents an efficient strategy to improve and maintain their gut health. The commensal probiotic, Faecalibacterium prausnitzii, is well known for its association with improved gut health in humans, farm animals and crustaceans. As such, increasing its abundance in the gut is of major interest and, moreover, identification of interventions able to support its growth is necessary. Undoubtedly, organic compounds, such as mixtures of organic acids, have a role in improving gut health and supporting the gut microbiota in either fighting disease or improving digestion. With this study, we aimed to further understand the biological mechanisms by which F. prausnitzii inhibits pathogenic bacteria, in the presence of organic acids. Furthermore, we have also investigated the organic acid ability to stimulate bacterial growth in vitro and ex vivo. Herein we show that a mixture of organic acids, AuraAqua (Aq) leads to improved F. prausnitzii growth and butyrate production which consequently reduces V. parahaemolyticus infection of shrimp gut primary epithelial cells. Increasing the abundance of probiotic bacteria in the gut requires either direct dietary supplementation or the inclusion of feed additives able to support the growth of beneficial commensal bacteria. In crustaceans, the increased presence of probiotic-like bacteria in the gut, including of Faecalibacterium prausnitzii (F. prausnitzii), will guarantee a positive health status and a gut environment that will ensure enhanced performance. The aim of this study was to investigate if a mixture of organic acids, AuraAqua (Aq) can stimulate the growth and the anti-pathogenic efficacy of F. prausnitzii through a combination of in vitro and ex vivo models. The results showed that 0.5% Aq was able to improve the growth rate of F. prausnitzii in vitro and in an ex vivo shrimp gut model. Moreover, we were able to demonstrate that Aq increases butyrate production and cellulose degradation in culture or in the shrimp gut model. The growth-stimulating effect of Aq also led to an improved and anti-pathogenic effect against Vibrio parahaemolyticus in a co-culture experiment with shrimp gut primary epithelial cells (SGP). In conclusion, our work demonstrates that Aq can stimulate the growth of F. prausnitzii, increase the production of short-chain fatty acid (SCFA) butyrate, improve substrate digestion, and prevent V. parahaemolyticus invasion of SGP cells.

13. Anti-CampylobacterProbiotics: Latest Mechanistic Insights

Author

Abstract

The Campylobactergenus is the leading cause of human gastroenteritis, with the consumption of contaminated poultry meat as the main route of infection. Probiotic bacteria, such as Lactobacillus, Bacillus, Escherichia coliNissle, and Bifidobacteriumspecies, have a great immunomodulatory capacity and exhibit antipathogenic effects through various molecular mechanisms. Reducing Campylobacterlevels in livestock animals, such as poultry, will have a substantial benefit to humans as it will reduce disease transmissibility through the food chain. Moreover, probiotic-based strategies might attenuate intestinal inflammatory processes, which consequently reduce the severity of Campylobacterdisease progression. At a molecular level, probiotics can also negatively impact on the functionality of various Campylobactervirulence and survival factors (e.g., adhesion, invasion), and on the associated colonization proteins involved in epithelial translocation. The current review describes recent in vitro, in vivo, and preclinical findings on probiotic therapies, aiming to reduce Campylobactercounts in poultry and reduce the pathogen's virulence in the avian and human host. Moreover, we focused in particular on probiotics with known anti-Campylobacteractivity seeking to understand the biological mechanisms involved in their mode of action.

14. The Physico-Chemical Composition and the Level of Metals From (Buletus Edulis) and (Cantharellus Cibarius) From the Vatra Dornei Area

Abstract

In general, wild mushrooms are considered are an excellent source of valuable nutritional compounds but can exerttoxic potential due to the accumulation of heavy metals. In the present study the basic physicochemical composition (fat, protein, and moisture) and heavy metal content profile (Pb, Cd, Cs) of two popular edible wild mushrooms of the species Boletus edulis and Cantharellus cibarius harvested from the forests of Vatra Dorna, Romania were determined. Both investigated mushrooms samples demonstrated a good protein source with the means ranged from 1.58-2.91. In addition,analyzed mushrooms showed a low-fat content presenting values of 0.41- 0.45. Inductively coupled plasma massspectrometry technique (ICP-MS) presents heavy metal content from B. edulis and C. cibarius samples ranged from 0.9 - 0.12 for Pb and 0.16 - 0.25 for Cd, respectively
