background : lactobacilli are the well known friendly bacteria for their probiotic activities against pathogens. the inhibitory activity of different strains of lactobacilli either obtained as commercial products or isolated from human feces was investigated against the clinical isolates of pseudomonas aeruginosa. the isolates were selected as the most resistant strains when challenged with ant...

Objective The objective of this study was to evaluate the antimicrobial activity of Mineral trioxide aggregate e Portland cement against some selected cariogenic bacteria. Methods Wells were made of approximately 0.5 mm in diameter, in solid culture media and immediately filled with cement. Twelve samples of each material were obtained for the realization of the agar diffusion method. These sam...

The present study was designed to investigate the effects of inulin and glycerol supplementation on physicochemical properties of probiotic frozen yogurt. Frozen yogurt was prepared with different types of probiotic (Lactobacillus acidophilus and Bifidobacterium lactis) along with yogurt starter culture (Streptococcus thermophilus and Lactobacillus bulgaricus). The frozen yogurt mixture was sup...

A personalized probiotic microfluidic chip system has been established and used to screen the probiotics which had the highest value of IFN-γ/IL-10 or IL-10/IFN-γ among six probiotics, including L. paracasei BRAP01, L. acidophilus AD300, B. longum BA100, E. faecium BR0085, L. rhamnosus AD500, and L. reuteri BR101. One hundred volunteers were included and their PBMCs were collected and stimulate...

Intestinal epithelial cells can respond to certain bacteria by producing an array of cytokines and chemokines which are associated with host immune responses. Lactobacillus acidophilus NCFM is a characterized probiotic, originally isolated from human feces. This study aimed to test the ability of L. acidophilus NCFM to stimulate cytokine and chemokine production in intestinal epithelial cells a...

AIM The aim of the study was to assess the impact of the long-term use of the composite probiotics in patients after restorative proctocolectomy. METHOD Forty-three patients (20 females and 23 males, aged 21 to 68 years) after restorative proctocolectomy were included in the study. After randomization patients were divided into placebo group and treatment group with oral intake of probiotic c...

BACKGROUND Research from developing countries, such as Nigeria, on Lactobacillus species in the female urogenital tract and their role as a barrier to vaginal infection is limited. Therefore, the aim of this study was to assess the clinical biotherapeutic potential of indigenous Lactobacillus species. METHODS Antimicrobial metabolites production were characterised using simple and easily repr...

Strain R0052, isolated from a North American dairy starter culture, was initially identified as Lactobacillus acidophilus based on phenotypic analyses. However, upon sequencing the 16S rRNA gene, it became clear that the isolate was very highly related to Lactobacillus suntoryeus, Lactobacillus helveticus and Lactobacillus gallinarum, as similarities ranging from 99.3 to 99.8 % were observed. A...

abstract background and aim: oral infections and dental caries are considered as two serious public health problems, which inflict a costly burden on health care services worldwide, especially in the developing countries. the aim of this study was to evaluate the antibacterial activity of iranian licorice aqueous root extract on lactobacillus acidophilus in comparison with chlorhexidine. materi...
