Algal beta-(1,3)-glucan and its effect on infectious bursal disease vaccination in poultry

Vaccination is used as a control and prevention tool for infectious bursal disease (IBDV) in poultry. A new strategy for improving vaccination efficiency is the use of in-feed immune modulating ingredients. The aim of this study was to test if the use of beta-(1,3)-glucans in feed can enhance IBDV vaccination. The trial was conducted in ROSS 308 broilers. In the study, a negative control group (not vaccinated, not supplemented), a positive control group (vaccinated, not supplemented) and a treated group (vaccinated, supplemented with beta-(1,3)-glucan) were included. All broilers, except the negative control, were orally vaccinated at 18 days of age with a live IBDV vaccine. Blood samples were taken at day 18 and 35 to measure antibody titers against IBDV. Serological analysis showed the presence of maternal derived antibodies at time of vaccination in some birds. The beta-(1,3)-glucan supplemented birds showed decreased CV% (coefficient of variation) and significantly increased average antibody titers compared to non-supplemented vaccinated birds. Additionally, the beta-(1,3)-glucan group showed increased number of birds with antibody titers above the titer threshold for protective immunity. The results obtained in the current trial clearly indicate that beta-(1,3)-glucan can increase seroconversion and serological response to IBDV vaccination.

Trigona honey (TH) is well known for its therapeutic characteristics. To date, the study of Trigona honey as a prophylactic or immune booster prior to the bacterial infection of the invivo model is not well covered. This study aims to investigate anti-inflammatory and immune activities in Wistar rats infected with respiratory infection following with Trigona honey. 25 Wistar rats were assigned to possitive groups, negative control group, positive control group was fed TH (5 g / kg body weight) orally, the untreated group was infected with Staphylococcus aureus to induce respiratory infection, the treated group has been infected with S. aureus followed by treatment with TH at a dose of 1.5 ×108 CFU / mL and the preventive group ingested TH one week before S. aureus infection. Blood was obtained for biochemical analysis. Lung tissues have been collected for molecular examination. The results showed a significant decrease in serum levels of ALT, AST, urea and creatinine in the preventive and treated groups, serum IgG increased significantly (P<0.05) in the preventive and treated groups, IFN-y increased in the preventive group while decreased in the treated group, and IL-8 increased in the treated group while decreased in the preventive group. The mRNA expression of AGP is up-regulated in the positive control, preventive and treated groups. The α2-MG, TNF-α , and mRNA expressions showed lower regulation after administration of TH in preventive and treated groups. The results show the ability of TH to counteract immune and inflammatory changes in serum levels and gene expressions.

AbstractSchistosomiasis is an acute and chronic disease caused by blood flukes (trematode worms) of the genus Schistosoma. Schistosomiasis is disease that are prevalent in or unique to tropical and subtropical regions. Previous studies have shown that the role of bone marrow mesenchymal stem cells (BMSCs) therapy in improvement of hepatic fibrosis. Therefore, the current study was designed to assess the therapeutic role of BMSCs in murine schistosomiasis mansoni. BMSCs derived male mice were intraperitoneal injected into female mice that received S. mansoni cercariae through subcutaneous route. Mice were divided into four groups: negative control group (noninfected non treated); positive control group (infected non treated); BMSCs treated group; and untreated group. Liver histopathology and immunohistochemically were evaluated. BMSC intraperitoneal injection resulted in a significant reduction in liver collagen, granuloma size, and significant increase in OV-6 expression in the Schistosomiasis treated mice group. There was overall improvement of the pathological changes of the liver. The findings support that BMSCs has a regenerative potential in the histopathology and function of the liver tissue by decreasing liver fibrosis.

Salmonella is one of the most harmful pathogens responsible for foodborne outbreaks, illnesses and deaths. The aim of this study was to evaluate the effect of potentially probiotic strains against Salmonella Typhimurium DT104 in mice. The compatibility test among the selected potential probiotic strains (Lactobacillus plantarum K132, Lactobacillus paracasei K114 and Lactococcus lactis E124) using the cross-streaking method showed the absence of antagonism. The anti-Salmonella activities of coculture of the isolated potential probiotics in the form of mixed or single culture showed a remarkable anti-Salmonella activity with 96.50 to 100% growth inhibition. The combination of strains, which showed the highest growth inhibition rates against Salmonella Typhimurium DT104, was used to test their effect on the colonization of mice by Salmonella Typhimurium DT104. White albino male mice were pretreated with the mixed potential probiotics for 7 days and infected with Salmonella Typhimurium DT104 for 1 day. A total of 3 treatments were applied, during which the negative control group was treated with phosphate-buffered saline (PBS); a positive control group (typ) was challenged with Salmonella Typhimurium DT104 alone. The treated group (pro-typ) was pretreated with mixed potential probiotic culture and then infected with Salmonella Typhimurium DT104. The survival rate of mice and counts of Salmonella in feces were recorded. The survival rate of mice on day 21 after the oral challenge with Salmonella Typhimurium DT104 was significantly p<0.05 higher in the experimental pro-typ group (100% survival) compared with the positive control group (20% survival). The counts (colony-forming unit per ml) of Salmonella in feces were significantly lower p<0.05 for the pro-typ group compared to the typ group. The combination of potential probiotic strains was able to protect mice against Salmonella Typhimurium DT104 infection that demonstrates their potential to be used as probiotic cultures for the production of functional fermented products.

The aim of this study was to compare the vertical fracture resistance of roots obturated with different root canal filling materials and sealers. Crowns of 55 extracted mandibular premolar teeth were removed to provide root lengths of 13 mm. Five roots were saved as negative control group (canals unprepared and unfilled). Fifty root canals were instrumented and then five roots were saved as positive control group (canals prepared but unfilled). The remaining 45 roots were randomly divided into three experimental groups (n=15root/group) and obturated with the following procedures: in group 1, glass ionomer-based sealer and cone (ActiV GP obturation system); in group 2, bioceramic sealer and cone (EndoSequence BC obturation system); and in group 3, roots were filled with bioceramic sealer and cone (Smartpaste bio obturation system). All specimens were tested in a universal testing machine for measuring fracture resistance. For each root, the force at the time of fracture was recorded in Newtons. The statistical analysis was performed by using Kruskal-Wallis and post hoc test. There were no significant differences between the three experimental groups. The fracture values of three experimental and negative control groups were significantly higher than the positive control group. Within the limitations of this study, all materials increased the fracture resistance of instrumented roots.
