| maternal supplementation with lgg reduces vaccine-specific immune responses in infants at high-risk of developing allergic disease. | probiotics are defined as live micro-organisms that when administered in adequate amounts confer a health benefit on the host. among their pleiotropic effects, inhibition of pathogen colonization at the mucosal surface as well as modulation of immune responses are widely recognized as the principal biological activities of probiotic bacteria. in recent times, the immune effects of probiotics have led to their application as vaccine adjuvants, offering a novel strategy for enhancing the efficacy ... | 2013 | 24324465 |
| effects of probiotics on the recurrence of bacterial vaginosis: a review. | bacterial vaginosis (bv) is a common cause of genital discomfort in women in reproductive ages, which causes many complications. bacterial vaginosis is usually treated by metronidazole and clindamycin. however, this protocol does not prevent its recurrence, which is a main complaint of the patients. the number of lactobacilli in the vagina of women with bv is significantly lower than that in healthy women. hence, efforts have been made to normalize vaginal flora by oral or vaginal administration ... | 2014 | 24299970 |
