47f: Bioadaptation to Low Doses of Xenobiotics in Aquaculture.

Agricultural and industrial activities are increasing pollution of water bodies with low doses of xenobiotics that have detrimental effects on aquaculture. The aim of this work was to determine the possibility of using 47f culture in fish aquaculture under the influence of low doses of xenobiotics as an adaptogen. An increase in the survival of individuals exposed to the xenobiotic bisphenol A solution and fed with the 47f was shown compared to control groups and, at the same time, the cytokine profile in the intestinal tissues of was also investigated.

The use of omics technologies in creating LBP and postbiotics based on the U-21.

In recent years, there has been an increasing tendency to create drugs based on certain commensal bacteria of the human microbiota and their ingredients, primarily focusing on live biotherapeutics (LBPs) and postbiotics. The creation of such drugs, termed pharmacobiotics, necessitates an understanding of their mechanisms of action and the identification of pharmacologically active ingredients that determine their target properties. Typically, these are complexes of biologically active substances synthesized by specific strains, promoted as LBPs or postbiotics (including vesicles): proteins, enzymes, low molecular weight metabolites, small RNAs, etc.

The Effects of Acute Bisphenol A Toxicity on the Hematological Parameters, Hematopoiesis, and Kidney Histology of Zebrafish ().

In this study, the results of evaluating the acute toxicity of Bisphenol A on are presented, encompassing peripheral blood parameters, the composition of hematopoietic cells of erythroid and myeloid lines in the head kidney, and data from histological studies. The LC50 values of Bisphenol A for adult zebrafish individuals for 12, 24, and 48-96 h were determined, which were 18.04, 7.

Ability of 47f to Alleviate the Toxic Effects of Imidacloprid Low Concentration on the Histological Parameters and Cytokine Profile of Zebrafish ().

In the present article, the possible mitigation of the toxic effect of imidacloprid low-concentration chronic exposure on by the probiotic strain 47f (1 × 10 CFU/g) was examined. It was found that even sublethal concentration (2500 µg/L) could lead to the death of some fish during the 60-day chronic experiment. However, the use of 47f partially reduced the toxic effects, resulting in an increased survival rate and a significant reduction of morphohistological lesions in the intestines and kidneys of .
