Evaluation of Prebiotic and Probiotic Effects on the Intestinal Gut Microbiota and Histology of Atlantic salmon (Salmo salar L.)

“…In fish studies, the antagonistic effect of LAB has been carried out on Gram-negative fish pathogens such as V anguillarum and A salmonicida [3,21,[38][39][40]. In the present study strong growth inhibition of Y. rückeri was recorded from extracellular extracts from late exponential growth phase from all of the eleven Carnobacteria strains isolated from the ex vivo experiments.…”

Antibiotics in Aquaculture – Use, Abuse and Alternatives

“…The most studied are lactic acid bacteria (LAB) (Lactobacillus, Carnobacterium, Enterococcus, Lactococcus, Micrococcus, Streptococcus, and Weissella) (Balcazar et al, 2008;Balcázar et al, 2007;Hagi & Hoshino, 2009;Pérez-Sánchez et al, 2011;Vazquez et al, 2005;Villamil et al, 2002), Bacillus (Ai et al, 2011;Antony et al, 2011;Balcázar & Rojas-Luna, 2007;Bandyopadhyay & Das Mohapatra, 2009;Ochoa-Solano & Olmos-Soto, 2006;Liu et al, 2009;Nakayama et al, 2009;Newaj-Fyzul et al, 2007;Olmos et al, 2011;Salinas et al, 2005;Sun et al, 2010;Vaseeharan & Ramasamy, 2003), Vibrio (Fjellheim et al, 2007;Thompson et al, 2010), Pseudomonas (Abd El-Rhman et al, 2009;Chythanya, 2002;Das et al, 2006;Preetha et al, 2007;Ström-Bestor, Wiklund, 2011), and Aeromonas (Irianto et al, 2003;Lategan et al, 2006;. Yeasts (Saccharomyces, Debaryomyces) (Abdeltawwab et al, 2008;Reyes-Becerril et al, 2008;Tovar-Ramírez et al, 2010), bacterial spore formers (Hong et al, 2005) and recently Actinobacteria have also generated interest due to their high metabolic potential (Das et al, 2010;You et al, 2007).…”

Probiotics in Aquaculture - Benefits to the Health, Technological Applications and Safety

“…Intake of probiotics has been demonstrated to modify the composition of the microbiota, and therefore assist in returning a disturbed microbiota (by antibiotics or other risk factors) to its normal beneficial composition (Gómez and Balcázar, 2008). As for the mechanisms during this physiological process, the production of antimicrobial substances, competition for nutrients or adhesion receptors, inhibition of virulence gene expression and enhancement of the immune response are all included (Irianto and Austin, 2002;Nikoskelainen, et al, 2003;Vine et al, 2004;Kim and Austin, 2006;Balcázar, et al, 2007). However, the exact mechanism by which these probiotics do this is not known.…”
