BACKGROUND The present work was planned to evaluate the antihyperglycemic, lipid-lowering, and antioxidant effect of Lactobacillus casei and Bifidobacterium bifidum in streptozotocin (STZ)-induced diabetic rats. METHODS Single daily dose of 1 × 10(7) cfu/ml of L. casei and B. bifidum alone and in combination of both was given to Wistar rats orally by gavaging for 28 days. Glucose tolerance te...

Although it is clear that probiotics improve intestinal barrier function, little is known about the effects of probiotics on the aging intestine. We investigated effects of 10-week bacterial supplementation of Lactobacillus plantarum WCFS1, Lactobacillus casei BL23, or Bifidobacterium breve DSM20213 on gut barrier and immunity in 16-week-old accelerated aging Ercc1-/Δ7 mice, which have a median...

A total of 109 lactic acid bacteria isolated from infant faeces were identified by partial 16S rRNA, cpn60 and/or pheS sequencing. Lactobacillus was the most prevalent genus, representing 48% of the isolates followed by Enterococcus (38%). Lactobacillus gasseri (21%) and Enterococcus faecalis (38%) were the main species detected. A further selection of potential probiotic starter cultures for f...

Lactobacillus casei is a Gram positive lactic acid bacterium used in dairy fermentations and present in the normal human gut microbiota. Certain strains are recognized as probiotics with beneficial effects on human and animal health. L. casei BL23 is a potential probiotic strain endowed with anti-inflammatory properties and a model strain widely used in genetic, physiological and biochemical st...

The chromosomal ccpA gene from Lactobacillus casei ATCC 393 has been cloned and sequenced. It encodes the CcpA protein, a central catabolite regulator belonging to the LacI-GalR family of bacterial repressors, and shows 54% identity with CcpA proteins from Bacillus subtilis and Bacillus megaterium. The L. casei ccpA gene was able to complement a B. subtilis ccpA mutant. An L. casei ccpA mutant ...

materials and methods s. sonnei and s .flexneri was identified by common microbiological and serological methods. antibiogram with 18 antibiotics were tested for 34 positive cultures by disc diffusion method. the samples showed considerable resistance to antibiotics. antimicrobial effects of cfcs were tested against s. sonnei and s. flexneri by agar-well assay and broth micro dilution methods. ...

Background: Food preservation includes procedures to assure higher level of food safety, hygiene and stability. To achieve this goal, the use of combination biopreservatives, such as Essential oils and Probiotics, has gained increased attention. Objective: The aim of this study was to evaluate the antimicrobial effects of Mentha longifolia L. esential oil and Lactobacillus casei aginst Listeri...

Background: The application of natural antimicrobial and antioxidant agents in food pharmaceutical products has recently become a trend due to the high demand for them from consumers. Postbiotics are bioactive compounds that produced when healthy bacteria gut ferment fiber. Objectives: This study aimed compare antibacterial properties postbiotics 5 different lactic acid (LAB) including Lactipla...
