“…Previous studies have shown that Acinetobacter only causes the infection of humans ( Carvalheira et al, 2021 ). But now, some members of the Acinetobacter genus can cause the diseases of fish ( Cao et al, 2016 ; Kuebutornye et al, 2020 ). Potential pathogens in the gut microbiota can cause damage when host immunity is low ( Pérez-Sánchez et al, 2018 ).…”

The effect of structure of gut microbes on the health of host has attracted increasing attention. Sea bass Lateolabrax japonicus is an important farmed fish in China. The relationship of the dynamic changes of intestinal bacterial communities in L. japonicus and the cultural water environment is very important for healthy culture. Here, the diversity and abundance of the gut microbial communities of L. japonicus were evaluated during the culture using 16S rRNA Illumina sequencing. Both the opportunistic pathogens Aeromonas (1.68%), Vibrio (1.59%), and Acinetobacter (1.22%); and the potential probiotics Lactobacillus (2.27%), Bacillus (1.16%), and Lactococcus (0.37%) were distributed in the gut of L. japonicus. The increasing concentration of nitrogen of water environments with the increase of culture time significantly correlated with shifts in the microbial community structure: 40.04% of gut microbial changes due to nitrogen concentration. Higher concentrations of nitrogen showed a significantly negative correlation with intestinal probiotics in L. japonicus. The results indicate that the abundance of intestinal bacteria of L. japonicus is mainly driven by the changes of environmental factors (e.g., nitrogen), and it’s very important that the linking environmental parameters with bacterial data of guts could be used as an early warning indicator in L. japonicus heath culture.

“…Due to its high protein content and fast growth rate, channel catfish have become a popular aquaculture crop. However, outbreaks of diseases have restricted the sustainable development of the channel catfish breeding industry and annual productivity [ 27 , 28 ]. It is urgent to investigate the molecular mechanisms beyond the immune responses of channel catfish during pathogen infection.…”

IL-10 and IL-6 play important roles in protecting against inflammation and clearing pathogens from the body. In this study, homologous compounds of IL-10 and IL-6 were identified in channel catfish, and their immune responses were analyzed. The CDS sequences of IL-10 and IL-6 were 549 bp and 642 bp, respectively, and showed the highest homology with Ameiurus melas. In addition, the expression of the IL-10 and IL-6 genes was ubiquitous in all 10 tissues examined. IL-10 is highly expressed in the liver and slightly expressed in the gills. The high expression of the IL-6 gene was observed in the spleen, heart, and gonads, with the lowest levels in the liver. LPS, Poly(I:C), PHA, and PMA showed a highly significant increase in IL-10 and IL-6 expression 48 h after CCK stimulation (p < 0.01). Genes were activated following immunostimulation with Streptococcus iniae, a channel catfish virus, and deltamethrin, respectively, following being challenged. Our results suggest that IL-10 and IL-6 are involved in the immune response of the host against the pathogen.

This study was aimed to analyze the effects of the nitrogen foliar application, and elicitation used on microbial populations of musts. The nitrogenous compounds were raw and treated wastewater from mushroom industry and a commercial yeast derivate; the elicitors were methyl jasmonate, chitosan and one commercial elicitor from a yeast source. Those six products were sprayed as pre-harvest treatment over the leaves of Tempranillo grapevines for improving quality and maturity of grapes. The applications of raw and treated wastewaters from mushroom industry, chitosan and methyl jasmonate elicitation did not cause changes in microbial diversity of must samples. In contrast, spraying commercial yeast derivate products made the must microbiota reach a high richness of species that would be positive in ecological terms. This research succeeded in establishing the impacts of foliar applications in the grapevines on the microbial community, and in any case, negative impacts were observed so that, presumably, these foliar applications can be perfectly implemented as agronomic practice.
