Lactobacillus strains are a major part of the probiotics, microflora of the intestine and of fermented dairy products, and are found in a variety of environments. The aim of this study was to find out the ability of bile and acid tolerance and antibacterial properties of the twenty eight isolates of three group lactobacilli namely Lactobacillus plantarum, Lactobacillus casei and Lactobacillus d...

Lactobacilli are well reckoned for their technological and probiotic significance and their exercise in dairy products for trade and industry. The present study was carried out to isolate and characterize Lactobacilli from various dairy and non dairy sources of Indian origin. The isolates were subjected to phenotypic and genotypic characterizations followed by partial 16S rDNAsequencing . As ma...

The ingestion of lactobacilli is of great importance for the probiotic effect of host gut Peyer's patches (PPs) macrophages. The present study is in time focus on the investigation of the factors determining the ingestion of lactobacilli by PPs macrophages. Physicochemical properties of cell surface and adhesive property of nine Lactobacillus strains were examined in the present work. The assoc...

The distribution, enumeration, and identification of lactobacilli on vegetable plants were studied in an area described geographically as being subtropical and moist. The lactobacilli were obtained, by means of quantitative enrichment procedures in Rogosa's SL broth, from 35.3% of all samples incubated at 32 C, and from 15.4% of the samples incubated at 45 C. Less than 10 lactobacilli/g of plan...

OBJECTIVE To study the antimicrobial susceptibility of six vaginal probiotic lactobacilli. METHODS The disc diffusion method in Müeller Hinton, LAPTg and MRS agars by the NCCLS (National Committee for Clinical Laboratory Standards) procedure was performed. Due to the absence of a Lactobacillus reference strains, the results were compared to those of Staphylococcus aureus ATCC29213. Minimal In...

Microbial ecology and dysbiosis are topics worthy of study. This review article will be the first of a two-part series that will discuss normal flora and threats to its ecology resulting in dysbiosis. Microorganisms are generally required to attain critical population increases before they threaten the host. The research on the role of bacterial microorganisms which are considered to be part of...

DENEV, S. A., 2006. Role of Lactobacilli in gastrointestinal ecosystem. Bulg. J. Agric. Sci., 12: 63-114 Lactobacilli are normal and important inhabitants of the gastrointestinal tract of human and animals. They constitute an integral part of healthy gastrointestinal microecology and have received considerable scientific attention. The role that lactobacilli play in the ecology of the gastroint...

To understand the role of mucosa-associated microbiota in the pathogenicity of ulcerative colitis (UC), paired biopsies were obtained during colonoscopy from the ulcerated and nonulcerated gut mucosa of 24 patients with UC. Denaturing gradient gel electrophoresis analysis was employed to profile the composition of the dominant bacteria (16S rRNA gene V3 region) and three important groups: lacto...

Lactobacilli are known to prevent colonization by many pathogens; nevertheless, the mechanisms of their protective effect are largely unknown. In this work, we investigated the role of lactobacilli during infection of epithelial cells with group A streptococci (GAS). GAS cause a variety of illnesses ranging from noninvasive disease to more severe invasive infections, such as necrotizing fasciit...
