Intestinal mucosal scrapings (48) were collected from twelve, 6 month old, Large White Yorkshire pigs after slaughter. Isolates (23) that were gram positive rods, were alone subjected to physiological tests (growth at pH: 4.5, 9.5; temperature; 15, 45°C; and NaCl: 2, 6.5%), four isolates exhibited no growth at all conditions studied and were rejected. Biochemical tests on the remaining nineteen...

One hundred and twenty-five acid-resistant presumptive lactobacilli were isolated from Slovak Bryndza cheese and screened for their antimicrobial activity against eight bacterial pathogens using spot agar assay. Out of twenty-six Lactobacillus strains with strong inhibition activity, twenty were identified as Lactobacillus plantarum and six as Lactobacillus fermentum. The most active eleven L. ...

BACKGROUND Two overlapping genes lacL and lacM (lacLM) encoding for heterodimeric β-galactosidase from Lactobacillus reuteri were previously cloned and over-expressed in the food-grade host strain Lactobacillus plantarum WCFS1, using the inducible lactobacillal pSIP expression system. In this study, we analyzed different factors that affect the production of recombinant L. reuteri β-galactosida...

The growth and viability of three Lactobacillus strains, Lactobacillus acidophilus, Lactobacillus plantarum and Lactobacillus rhamnosus, after their passage through simulated gastric and pancreatic juices were studied as a function of their presence in the growth medium of rocket salad (Eruca sativa). The presence of E. sativa affected some of the biological properties of the strains. For examp...

OBJECTIVE To assess the efficacy of probiotic Lactobacillus on serum lipids using a meta-analysis of randomized, controlled trials. METHODS Fifteen studies containing 15 trials, with 976 subjects were included. The pooled WMD was calculated by random effects model. RESULTS Probiotic Lactobacillus consumption significantly reduced TC by 0.26mmol/l (95% CI, -0.40 to -0.12) and LDL-C by 0.23mm...

Backgrounds : The role of potentially probiotic lactic acid bacteria of human milk   in  the  early  colonization and protection of infant against infections is the subject of increasing researches. Colonization with Lactobacillus plantarum in early infancy is suggested to be important for health in later life. However, we presently investigated the strain of Lactobacil...

BACKGROUND Chronic suppurative otitis media can be recalcitrant and difficult to treat, particularly with the increasing occurrence of antibiotic resistance. Lactobacillus plantarum is a probiotic that has been shown to decrease S. aureus and P. aeruginosa growth in wounds, making it a good candidate for the treatment of chronic suppurative otitis media. However, before it can be applied in the...

The genus Lactobacillus contains over 80 recognized species, and is characterized by a high level of diversity, reflected in its complex phylogeny. The authors' recent determination of the genome sequence of Lactobacillus salivarius means that five complete genomes of Lactobacillus species are available for comparative genomics: L. salivarius, L. plantarum, L. acidophilus, L. johnsonii and L. s...

the lactic acid bacteria in 9 samples of the fermented camel milk, chal, taken from rural area and retail markets were identified on the basis of their physiological and morphological properties. from the samples, 93 lab species including, 64 bacillus (68.8%), 8 cocci 8.6%), 11 coccobacillus (11.83%), 2 streptococcus (2.15%) and 8 tetrade (8.6%) were identified. among the lactobacillus species,...
