“…The digestibility value of feed crude fiber of C15 was higher than those of the other three groups; the digestibility values of the C15 and C1573 were significantly higher than that of the control group (P<0.01); the difference in the digestibility value between C73 and control was not significant. Previous studies regarding Lactobacillus colonization of the chicken gut were mainly concerned with mucosal immunity against pathogenic microorganisms (Dalloul et al 2005;Radhika et al 2020). In the present study, the effect of recombinant Lactobacillus on feed crude fiber digestibility was analyzed.…”

“…The production and use of feed cellulase has been employed to solve this problem (Ravindran et al 2007); however, the expected outcomes have not yet been accomplished (Liu et al 2016). Previous studies on animal feed with viable bacteria carrying exogenous genes have mainly focused on immunization (Lv et al 2017;Radhika et al 2020), while studies with viable bacteria carrying cellulase genes remain limited. Most current methods use bioengineered feed cellulase as a feed additive (Song et al 2013) and viable bacterial preparations (i.e.…”

Background: The aim of this test was study the gut adhesion ability of recombinant Lactobacilli and their improvement of the digestibility of crude fiber in chick diet. Methods: The adhesion ability was observed through in vitro and in vivo tests. Intestinal epithelial cells and recombinant Lactobacillus were co-cultured for observation of adhesion. One hundred one-day-old chicks were randomly divided into four groups; C15, C73, C1573 and control. Each chick in C15, C73, C1573 and control were orally gavaged with 200 ìL of fermentation broth of recombinant L. reuteri XNY-Cel15, 200 ìL of fermentation broth of recombinant L. reuteri XNY-Cel73 and 200 ìL of broth containing equal XNY-Cel15 and XNY-Cel73, 200 ìL of MRS broth, once at the beginning of the trial respectively. Result: Recombinant L. reuteri adhered to chick intestinal epithelial cells which co-cultured together in vitro. After feeding for 30 days, the reporter genes of recombinant Lactobacillus was detected in the crop, small intestine and cecum of trial chicks, with their sequences corresponding to those of the insert genes. The digestibility of crude fiber in experimental groups was higher than that in control group and the digestibility of C15 was significantly higher than other groups (P less than 0.01). It showed that the recombinant Lactobacillus can survive in the digestive tract of chicken for more than 30 days and helped to decompose the crude fiber in the digestive tract.

“…The relative abundance of some of these species correlated with certain immune factors and physiological parameters [18]. Some effects of probiotic modulation include cytokine production by epithelial cells, increased mucin secretion, increased phagocytosis activity and activation of T cells and natural killer T cells, stimulation of IgA production, and decreased T cell proliferation [1,[19][20][21][22][23][24]. Noteworthy are the studies conducted by Uyeno et al on Holstein calves treated with a probiotic consisting of L. plantarum, Enterococcus faecium, and Clostridium butyricum.…”

Background and Aim: Various means and methods, including probiotics and biologically active additives, have been developed and proposed for production to increase the immunobiological reactivity of the body, regardless of the etiology of its decrease. This study aimed to find out the immune status of calves during the preweaning period in association with Vetosporin Zh, Normosil, and Gumi-malysh. Materials and Methods: The research object was 30-day-old calves of black-and-white Holstein breed. The calves were divided into four groups of 20 heads each. The calves of the first, second, and third experimental groups were treated with Normosil probiotic, Vetosporin Zh probiotic, and Vetosporin Zh probiotic in combination with Gumi-malysh, respectively. The calves in the first, second, and third experimental groups were treated with Normosil probiotic, Vetosporin Zh probiotic, and Vetosporin Zh probiotic in combination with Gumi-malysh, respectively. Results: On days 10 and 21 of the experiment, animal blood was collected to determine the content of total protein, protein fractions, immunoglobulins, T and B lymphocytes, phagocytic activity and a phagocytic number of neutrophils, and circulating immune complexes (CIC). The combined use of Vetosporin Zh probiotic (dose, 20 mL) with Gumi-malysh (dose, 30 mL) per animal for 30 days in 1-month-old calves contributes to the increase in the number of T lymphocytes, B lymphocytes, and immunoglobulin A (IgA) and immunoglobulin G (IgG) levels by 2.9%, 3.8%, and 0.96 and 2 g/L, respectively, while reducing the immunoglobulin M (IgM) level; an increase in the phagocytic activity of blood neutrophils and the phagocytic number by 7% and 1.8%, respectively, as well as a decrease in the CIC level with similar indicators in calves that were not treated with the agents. Conclusion: The method used in the current study helps increase the number of T and B lymphocytes, increase IgA and IgG levels while reducing IgM levels, and increase the phagocytic activity and a phagocytic number of blood neutrophils, as well as decrease the CIC level.

“…CD 3 + , CD 4 + and CD 8 + T lymphocyte subpopulations mainly mediates cellular immunity (Radhika et al, 2020). Decrease of the number of T lymphocytes and subpopulationsis an important factor inducing immunosenescence (Aranburu et al, 2018, Xie et al, 2017.…”

Background: 6-furfuryloaminopurine (KT) is the first compound to be identified as a cytokinin. Despite that there are many studies related to KT but the mechanism of KT in resisting immunosenescence remains unclear. The objective of this study is to investigate the influences of KT on the immunity of thymus in rats by detecting the apoptosis and the proliferation index (PI).Methods: We firstly established an aging rat model by subcutaneously injecting D- galactose (D-gal, 125mg/kg•BW) in the dorsal neck of Sprague Daly rats (SD rats); then the rats were divided into KT treatment groups (three groups for different doses of KT), aging model group (without KT treatment) and young control group. The rats in KT treatment groups were treated with different-dose KT and the key indices including the changes of the number of CD3+, CD4+ and CD8+ T lymphocyte subpopulations in peripheral blood, the apoptosis of thymus lymphocytes. Result: KT could increase the number of the peripheral CD3+, CD4+ and CD8+ T lymphocytes of the aging rats while decreased the apoptotic rate of thymocytes and increased PI Index.
