Some Factors Affecting the Autoaggregation Ability of Vaginal Lactobacilli Isolated from Turkish Women

چکیده
In this work, autoaggregation and factors involved in the autoaggregation ability of vaginal lactobacilli were studied. The autoaggregation ability of 28 lactobacilli strains was positive. The effects of various factors on autoaggregation were also evaluated. Lactobacillus jensenii A1, L. salivarius I1, and L. cellobiosus I3 showed higher autoaggregation in acidic conditions and lower autoaggregation in hot (70 and 85oC) conditions. The L. salivarius I1 strain, which exhibited high autoaggregation activity, also showed good autoaggregation in pepsin, lipase, and sodium periodate, as well as under conditions of sonication and heat. The results of this study suggest that lactobacilli showing high autoaggregation may constitute an important host defense mechanism against infections as a probiotic.

Lactobacilli play an important role in maintaining vaginal health. However, during bacterial vaginosis lactobacilli decrease for unknown reasons. Our preliminary study showed that phages could infect vaginal lactobacilli. Therefore, the aim of this study was to analyze the distribution, virulence, and types of vaginal Lactobacillus phages isolated from women of two countries: the United States ...

OBJECTIVE During bacterial vaginosis, an unexplained decrease of vaginal lactobacilli occurs. To identify whether these lactobacilli could be infected by phages, we isolated phages from vaginal lactobacilli and analyzed their potential virulence in attacking vaginal lactobacilli in vitro. METHODS Vaginal samples were obtained from 39 reproductive-aged women. The selective Rogosa SL agar was u...

متن کاملAnalysis of Lactobacillus Products for Phages and Bacteriocins That Inhibit Vaginal Lactobacilli
OBJECTIVE Bacterial vaginosis is associated with an unexplained loss of vaginal lactobacilli. Previously, we have identified certain vaginal lactobacilli-released phages that can inhibit in vitro other vaginal lactobacilli. However, there is no apparent route for phages to be transmitted among women. The purpose of this study was to identify whether certain Lactobacillus products commonly used ...
