“…cremoris SMM69. The up-regulation of these genes has been previously reported in rainbow-trout head-kidney and/or spleen [18,19,46,59], sea bass (Dicentrarchus labrax L.) head-kidney [60], tilapia (Oreochromis niloticus) intestine [47], and Japanese pufferfish (Takifugu rubripes) head-kidney [16] fed with probiotic LAB or using in vitro co-cultures of fish cell lines and probiotic LAB. In spite of the up-regulation of pro-inflammatory cytokines in skin observed in our work, the expression of IL-1b gene was significantly down-regulated in other turbot organs such as head-kidney, spleen, liver or intestine.…”

Probiotics, which are considered as live microbial adjunct conferring health benefits to the host, represent a potentially effective strategy for infectious disease control. Nevertheless, there has been growing concerns about safety, applicability and functionality issues associated with the live probiotic microorganisms. Concurrently, recent observations indicate that even the non-viable counterparts of the probiotic organisms, also known as paraprobiotic, can be used to harness similar beneficial effects. Considering the limitations of probiotic application, paraprobiotics constitute a potential alternative strategy for improving health and wellness of fish and shellfish in aquaculture. Eventhough the concept of paraprobiotic is relatively established in higher vertebrate models and related food production sectors, its application in aquaculture is still in its early stage. In light of this, the present review delineates the concept of paraprobiotic, inactivation methods used for its preparation, the role of paraprobiotic in modifying biological responses as well as their potential application in aquaculture.

“…Román et al. () observed that cytokine gene expression is generally higher in leucocytes of European sea bass ( Dicentrarchus labrax L.) incubated with live probiotic Vagoccus fluvialis L‐21 and UV‐light inactivated probiotic, in contrast to those incubated with heat‐inactivated probiotic where less expression was observed. In an in vivo study Picchietti et al.…”

Supplementation of heat-inactivated Bacillus clausii DE5 in diets for grouper, Epinephelus coioides, improves feed utilization, intestinal and systemic immune responses and not growth performance

In recent years, more and more attentions have been paid to the development and application of probiotics in aquaculture, and viable probiotics have been extensively studied, while rare information was available about inactivated probiotics in aquaculture. Therefore, in this study, a feeding trial was designed to investigate the effect of dietary supplementation of heat-inactivated probiotic Bacillus clausii DE5 on growth performance, immune response and key immune genes expression in head kidney and intestine in grouper Epinephelus coioides. Fish were fed for 60 days with control diet (C) and two experimental diets containing 1.0 × 10 8 CFU/g live (T1) and heatinactivated (T2) B. clausii DE5, respectively. The probiotic treatments did not affect the final weight, weight gain (WG) and specific growth rate (SGR) of E. coioides at days 30 and 60 (p > .05), while both heat-inactivated and live B. clausii DE5 significantly decreased the feed intake and feed conversion ratio (FCR) at day 60 (p < .05). Serum lysozyme activity and complement C3 level in the two probiotic treatments were significantly higher than those in the control (p < .05). The lysozyme activity and complement C3 level at day 60 were significantly higher than those at day 30 (p < .05), while no significant interaction effect between diet and administration date was observed.Moreover, the heat-inactivated B. clausii DE5 significantly improved the expression of TLR5, pro-inflammatory cytokines (IL-8 and IL-1β) and TGF-β1 in head kidney and intestine (p < .05), while the live probiotic did not show any significant effect on the expression of these key immune-related genes in head kidney and intestine. These results indicate that dietary supplementation of heat-inactivated B. clausii DE5 effectively improved feed utilization and both the local and systemic immune responses of E. coioides.
