A potential protective effect of probiotic strains against zoonotic infection was investigated in the framework of a new therapeutic strategy aimed at using probiotics to control parasitic zoonoses. The study was focused on the impact of six selected probiotic (bacteriocinogenic) strains on the intensity of . infection and female fecundity and . Bacterial strains of different origin ( EF55, 2019 = CCM7420, AL41 = CCM8558, ED26E/7, AD1 = CCM7421, 17L/1) were administered daily in a dose of 10 CFU/ml in 100 μl, and mice were infected with 400 . larvae on day 7 of treatment. Female adults of . were isolated on day 5 post infection (p.i.) and subsequently were used in fecundity test . . CCM8558, . CCM7420 and . ED26E/7 strains significantly reduced the number of adults in the intestine. The application of . CCM7421, . 17L/1, . CCM8558 and . ED26E/7 caused a significant decrease in the number of muscle larvae. The treatment with . CCM8558 and . ED26E/7 showed the highest inhibitory effect on female fecundity (94 %). The number of newborn larvae (NBL) was also significantly decreased after administration of . CCM7421 and . 17L/1 (80 %). A direct impact of probiotic strains on female reproductive capacity was examined in females isolated from untreated infected mice on day 5 p.i. A correlation was found between the inhibitory effect and the concentration of probiotic strains. The reduction effects of the strains manifested as follows: . CCM7421 (93 %), . CCM8558, . 17L/1, . EF55 (about 80 %), . CCM7420 and . ED26E/7 (about 60 %).

Impact of commercial gut health interventions on caecal metagenome and broiler performance.

Background: Maintaining gut health is a persistent and unresolved challenge in the poultry industry. Given the critical role of gut health in chicken performance and welfare, there is a pressing need to identify effective gut health intervention (GHI) strategies to ensure optimal outcomes in poultry farming. In this study, across three broiler production cycles, we compared the metagenomes and performance of broilers provided with ionophores (as the control group) against birds subjected to five different GHI combinations involving vaccination, probiotics, prebiotics, essential oils, and reduction of ionophore use.

Levilactobacillus brevis YT108, identified for its ability to metabolize prebiotic xylo-oligosaccharides (XOS), emerges as a candidate for probiotic use in synbiotic food formulations. This study aimed to investigate the metabolic and genomic traits associated with XOS metabolism in YT108 and to assess its probiotic attributes through whole genome sequencing and in vitro assays. Strain YT108 exhibited robust growth kinetics on XOS as the sole carbon source, with a growth profile comparable to that on glucose, achieving a pH reduction to 4.
