conclusions in conclusion, we developed a method to express the papg.acma protein on the surface of lactobacillus. this is the first report on the successful application of lactic acid bacteria displaying the papg.acma fusion protein. it will be interesting to determine the immune responses against the papg protein in near future using this surface display strategy. results the papg.acma fusion...

BACKGROUND Lactic acid bacteria, especially Lactobacillus spp., have been considered as excellent probiotic microorganisms, because of their activities in reducing the enteric diseases and maintaining healthy poultry. OBJECTIVES The current study aimed to evaluate the phenotypic characteristics and the probiotic potentials of Lactobacillus spp. isolated from poultry. MATERIALS AND METHODS A...

Background/Aim. Probiotics help to provide an optimum balance in the intestines. Probiotics species competitive block toxic substances and growth of unwanted bacteria and yeast species while they compete for the space and food. Lactogyn® is the first oral probiotics on Serbian market dedicated to maintaining a normal vaginal flora. Lactogyn® contains two well studied probiotics strains – Lactob...

The protective effects of encapsulation on the survival of Lactobacillus reuteri and the retention of the bacterium's probiotic properties under simulated gastrointestinal conditions were investigated. Viable counts and the remaining probiotic properties of calcium (Ca)-alginate encapsulated (A group), chitosan-Ca-alginate encapsulated (CA group), and unencapsulated, free L. reuteri (F group) w...

background: feeding intolerance is a common problem among premature infants. there is limited information on the safety and effects of oral probiotic supplements, especially products containing lactobacillus reuteri, and the incidence of necrotizing enterocolitis (nec) in low birth weight preterm infants. this study aimed to evaluate the effects of lactobacillus reuteri on the gastrointestinal ...

Lactobacillus reuteri strain 121 employs a fructosyltransferase (FTF) to synthesize a fructose polymer [a fructan of the levan type, with beta(2-->6) linkages] from sucrose or raffinose. Purification of this FTF (a levansucrase), and identification of peptide amino acid sequences, allowed isolation of the first Lactobacillus levansucrase gene (lev), encoding a protein (Lev) consisting of 804 am...

The diversity and stability of the fecal bacterial microbiota in weaning pigs was studied after introduction of an exogenous Lactobacillus reuteri strain, MM53, using a combination of cultivation and techniques based on genes encoding 16S rRNA (16S rDNA). Piglets (n = 9) were assigned to three treatment groups (control, daily dosed, and 4th-day dosed), and fresh fecal samples were collected dai...

Heat shock proteins (HSPs) are a set of highly conserved proteins that can serve as intestinal gate keepers in gut homeostasis. Here, effects of a probiotic, Lactobacillus rhamnosus GG (LGG), and two novel porcine isolates, Lactobacillus johnsonii strain P47-HY and Lactobacillus reuteri strain P43-HUV, on cytoprotective HSP expression and gut barrier function, were investigated in a porcine IPE...
