Over the last few decades the prevalence of studies about probiotics strains has dramatically grown in most regions of the world. The use of probiotics strains in animals production may reduce several problems caused by antibiotics therapy, growth promoter and problems from inadequate management. Probiotics are specific strains of microorganisms, which when served to human or animals in proper amount, have a beneficial effect, improving health or reducing risk of get sick. This book provides the maximum of information for all that need them trying with this to help many people at worldwide....
Over the last few decades the prevalence of studies about probiotics strains has dramatically grown in most regions of the world. Probiotics are specific strains of microorganisms, which when served to human or animals in proper amount, have a beneficial effect, improving health or reducing risk of getting sick and the probiotics are used in production of functional foods and pharmaceutical products.
Abstract This study was conducted in order to evaluate the probiotic properties of lactic acid bacteria (LAB) isolated from intestinal tract of broilers and Thai indigenous chickens. The major properties, including the gastric juice and bile salts tolerance, starch, protein and lipid digesting capabilities, and the inhibition on certain pathogenic bacteria were investigated. Three-hundred and twenty-two and 226 LAB strains were isolated from ten broilers and eight Thai indigenous chickens, respectively....
The inhibitory activity of these spore-forming strains against Escherichia coli K88, E. coli K99, Salmonella typhimurium and Staphylococcus aureus was assessed using a disc plate diffusion assay. The six bacilli with the largest inhibition zones against the four indicator bacteria were chosen and assessed for their
These criteria are
classified into its safety profile, performance within the GI tract and technological
aspects of its development. The criteria are further dependent on the specific purpose
of the strain and on the location for the expression of the specific property. With
regards to safety, the probiotic strain must be of human origin, isolated from the
gastrointestinal tract (GIT) of healthy individuals.
The surface of the human gut has a surplus area of 200-250 m2 in order to contain, between
intraepithelial lymphocytes and lamina propria, Peyer’s patches and lymphoid follicles, the
lymphoid tissue, while hosts a flora of about 800 different bacteria species with over 7000
strains. The 99% are obligate anaerobes and varies species were then classified using
traditional anaerobic culture techniques.
In the present study intestinal delivery systems resistant to gastric juice, loaded with the probiotic bacteria Lactobacillus acidophilus LA14 and Bifidobacterium lactis BI07, were produced by the polyelectrolyte complexation. First, beads were prepared by the traditional extrusion method and nine formulations were developed using alginate as main carrier and the biopolymer, xanthan gum, as hydrophilic retardant polymer or the cellulose derivative, cellulose acetate phthalateDevelopment of microparticulate systems for intestinal delivery of Lactobacillus acidophilus and Bifidobacterium lactis.

The direct effect of probiotics
in the lumen include the competition with pathogens for nutrients, production of
antimicrobial substances and in particular organic acids competitive inhibition on the
receptor sites, change in the composition of mucin hydrolysis of toxins, receptor
hydrolysis, and nitric oxide (NO). The indirect effect of probiotics largely depends on
the site of interaction between the probiotic and the effectors of the immune response.
