چکیده: باکتری های اسید لاکتیک از 9 نمونه شیر تخمیری شتر، چال، جمع آوری شده از مناطق روستایی و سوپرمارکت ها، بر اساس خصوصیات موفولوژیکی و فیزیولوژیکی شناسایی شدند. از نمونه ها، 93 عدد باکتری اسیدلاکتیک شناسایی شد که شامل 64 عدد Bacillus (8/68%)، 8 عدد کوکسی (6/8%)، 11 عدد Coccobacillus (83/11%)، 2 عدد Streptococcus (15/2%) و 8 عدد تتراد (6/8%) بودند. در بین جنس لاکتوباسیلوس، Lactobacillus planta...
Dendritic cells (DCs) are critical for the generation of T-cell responses. DC function may be modulated by probiotics, which confer health benefits in immunocompromised individuals, such as the elderly. This study investigated the effects of four probiotics, Bifidobacterium longum bv. infantis CCUG 52486, B. longum SP 07/3, Lactobacillus rhamnosus GG (L.GG) and L. casei Shirota (LcS), on DC fun...
OBJECTIVE To estimate the efficacy of a probiotic yogurt compared to a pasteurised yogurt for the prevention of antibiotic-associated diarrhoea in children. DESIGN AND SETTING This was a multisite, randomised, double-blind, placebo-controlled clinical trial conducted between September 2009 and 2012. The study was conducted through general practices and pharmacies in Launceston, Tasmania, Aust...
در آزمایش حاضر اثرات تجویز خوراکی Lactobacillus rhamnosus بر شاخص‌های بیوشیمیایی خون ماهی قزل آلای رنگین کمان (Oncorhynchus mykiss) تحت استرس ناشی از سمیت تحت-کشنده‌ی مالاتیون بررسی شد. تعداد 180 ماهی با میانگین وزن اولیه 6/2±43 گرم به چهار گروه شاهد، پروبیوتیک، مالاتیون توام با پروبیوتیک و مالاتیون تقسیم شدند. غلظت انتخابی از مالاتیون 036/0 میلی‌گرم بر لیتر بود و مکمل L. rhamnosus به میزان 1...
Lactobacillus rhamnosus strain GG (LGG) has been studied extensively as a probiotic in humans. However, the ability of an organism to survive passage through the intestinal tract and exert beneficial effects cannot be directly extrapolated between species. This study evaluated the ability of LGG to survive gastrointestinal transit in dogs and assessed whether oral administration of LGG is safe,...
Background Lactobacillus rhamnosus Pen is a human endogenous strain with well-documented health promoting properties that is used for production of probiotics. It has a long safety history of application, and its effectiveness in the prevention of antibiotic-associated diarrhoea has also been confirmed in clinical trials. Results Here we present the complete genome sequence of L. rhamnosus Pe...
The use of essential oils in foods has attracted great interest, due to their antagonistic action against pathogenic microorganisms. However, this action is undesirable for probiotic foods, as products containing Lactobacillus rhamnosus. The aim of the present study was to measure the sensitivity profile of L. rhamnosus and a yogurt starter culture in fermented milk, upon addition of increasing...
Four Lactobacillus strains were isolated from marketed probiotic products, including L. rhamnosus strains from Vifit (Friesland Campina) and Idoform (Ferrosan) and L. casei strains from Actimel (Danone) and Yakult (Yakult Honsa Co.). Their genomes and phenotypes were characterized and compared in detail with L. casei strain BL23 and L. rhamnosus strain GG. Phenotypic analysis of the new isolate...
AIMS This study investigates the antagonistic effects of the probiotic strains Lactobacillus rhamnosus GR-1 and Lactobacillus reuteri RC-14 against vulvovaginal candidiasis (VVC)-causing Candida glabrata. METHODS AND RESULTS Growth inhibitory activities of Lact. rhamnosus GR-1 and Lact. reuteri RC-14 strains against C. glabrata were demonstrated using a spot overlay assay and a plate-based mi...
Exposure of the intestine to certain strains lactobacillus can have systemic immune effects that include the attenuation of allergic responses. Despite the central role of mast cells in allergic disease little is known about the effect of lactobacilli on the function of these cells. To address this we assessed changes in rat mast cell activation following oral treatment with a strain of Lactoba...
