conclusions our findings show that lactobacillus strains with human origin had a mild inhibitory activity against the diarrheagenic e. coli, and these strains may be useful as probiotic candidates in prevention of intestinal infections caused by diarrheagenic e. coli. results a total of 20 lactobacillus isolates were identified from stool samples. lactobacillus fermentum was the most frequently...

Lactobacillus and thrush prevention A randomised controlled trial1 has dashed the hope that eating, or putting preparations of lactobacillus into the vagina, prevents thrush. The aim of the study published in the British Medical Journal was to test whether oral or vaginal lactobacillus could prevent postantibiotic vulvovaginitis. The study recruited women aged 18–50 years with nongynaecological...

AIM To develop in vitro assays for comparing the antagonistic properties and anti-oxidative activity of probiotic Lactobacillus and Bifidobacterium strains against various entero- and urinary pathogens. METHODS AND RESULTS The antagonistic activity of five probiotic lactobacilli (Lactobacillus rhamnosus GG, Lactobacillus fermentum ME-3, Lactobacillus acidophilus La5, Lactobacillus plantarum 2...

AIM To evaluate the ability of Lactobacillus rhamnosus HN001 and Bifidobacterium longum BB536 to colonize the intestinal environment of healthy subjects and modify the gut microbiota composition. METHODS Twenty healthy Italian volunteers, eight males and twelve females, participated in the study. Ten subjects took a sachet containing 4 × 109 colony-forming units (CFU) of Bifidobacterium longu...

UNLABELLED Vancomycin-resistant enterococci (VRE) have become a major nosocomial threat. Enterococcus faecium is of special concern, as it can easily acquire new antibiotic resistances and is an excellent colonizer of the human intestinal tract. Several clinical studies have explored the potential use of beneficial bacteria to weed out opportunistic pathogens. Specifically, the widely studied L...

A radioirnmunoassay for SP1 (“pregnancy-specific” beta1-glycoprotein) is described in which a sensitivity of 0.1 tg/L was achieved by use of an antiserum with Ka 1.7 X lOll L/mol and delayed addition of a 1251-SP1tracer (specific acty, 25 Ci/g) that was stable for use in the assay for at least six to seven weeks. We also report an additional anti-SP serum, from an early bleeding, that displayed...
