چکیده
Relevance. The use of antibiotics to treat infections the reproductive tract in cows can cause bacterial resistance and endanger human health. Potentially, preparations from representatives lactic acid vaginal microflora (probiotics) be used as a biological control reduce animal husbandry.However, specific composition healthy dry its probiotic properties remain poorly documented. Methods. species identification catalase-negative gram-positive isolates bacteria forming colonies on MRS agar isolated utero-cervical mucus lactating was carried out accordance with standard procedures using culturedependent approach, biochemical tests for sugar fermentation API50 CHL strips (bioMеrieux, France). For testing antagonistic activity by method delayed antagonism against test cultures staphylococci Escherichia, 14 were selected typing assigned 5 genus Lactobacillus. Results. results obtained indicate that utero-vaginal biocenosis is represented microorganisms Lactobacillaceae family, including enterococci Leuconostocaceae family. presence genera Aerococcus, Peptostreptococcus Gardnerella vaginalis found without signs pathology birth canal. According obtained, population Lactobacillus has low or medium indicatory strains Escherichia.

some properties of fuzzy hilbert spaces and norm of operators
in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...

Background: Lactic Acid Bacteria are a group of Gram-positive bacteria which are widely used in the food industry as organic ferments called starter cultures. In this study, Enterococcus faecium, Leuconostoc mesenteroides, Lactococcus lactis, Weissella paramesenteroides, and Lactiplantibacillus plantarum isolated from Moroccan table olives were tested for their acquisition of probiotic and tech...

s: Probiotic mean live microorganisms that have beneficial effects on their host’s health. Although probiotic strains can be isolated from many sources; for human applications the main criteria is being human origin. Breast milk is an important nutrient source for neonates. Lots of studies showed that this fluid has beneficial effects on the health of neonates. One reason of being beneficial is...
