We aimed at evaluating the association between intestinal Lactobacillus sp. composition and their metabolic activity with the host metabolism in adult and elderly individuals. Faecal and plasma metabolites were measured and correlated to the Lactobacillus species distribution in healthy Estonian cohorts of adult (n = 16; < 48 y) and elderly (n = 33; > 65 y). Total cholesterol, LDL, C-reactive p...

Lactic acid fermentation is a natural method of antimicrobial food protection. Antagonistic activity of Lactobacillus sp. bacteria, taking part in this process, is directed mainly against the same or other microorganisms. In this work we determine the impact of the presence of xylitol and galactosyl-xylitol on the antagonistic activity of 60 Lactobacillus sp. strains against indicator molds (Al...

In the present study, polyphasic analysis [cultivation, combined with the fingerprinting of individual isolates, and denaturing gradient gel electrophoresis (DGGE)] was applied to study whether similar features concerning the diversity and temporal stability of selected bacterial groups could be detected intra-individually in two different niches - the oral cavity and the colon - from ten adult...

Bile salt hydrolases (BSH) results in microbes releasing enzymes conferring physiological functions for both the producing organisms and host subsequently lower serum cholesterol. In recent years, these attributes have generated interest towards screening of lactic acid bacteria (LAB) functional food production. this present study, lactobacilli (n=34) (13 L. casei, 6 paracasei, 11 brevis, 3 pen...

Objective: The aim of the present study was to assess the antithrombotic properties of different strains of orally available antithrombotic lactic acid bacteria (LAB). Research Methods & Procedures: Antithrombotic activity, antiplatelet reactivity and/or thrombolytic activity, were measured in seven strains of LAB and LAB cell-free-extracts (LAB filtrates) using the shear-induced platelet react...

Background: Lactic acid bacteria (LAB) are normal flora of the mouth, intestines and the female genital tract. They are also frequently found in meat, vegetables, and dairy products. Most of probiotic bacteria belong to the LAB group. Some probiotic LAB are useful in prevention and treatment of diarrheal diseases. The aim of this study was to investigate the antimicrobial properties of LAB isol...

This study describes selective plating methodologies for enumeration of mixed cultures of Streptococcus thermophilus, Lactobacillus delbrueckii subsp. bulgaricus, L. acidophilus, L. paracasei subsp. paracasei and Bifidobacterium lactis in fermented milk based on selective antibiotic-free media. Enumeration of S. thermophilus was performed using M17-lactose. MRS-fructose was suitable for enumera...

BACKGROUND Previous studies have shown that selected strains of lactobacilli that are administered orally result in a modest reduction of diarrhea duration. However, duration alone is not considered optimal for therapeutic evaluation of any agent in diarrhea. OBJECTIVE To examine the effect of a new probiotic, Lactobacillus paracasei strain ST11 (ST11), in acute childhood diarrhea by using ev...
