In a recent study, we examined the glycemic and autonomic nervous responses to probiotic strain Lactobacillus johnsonii La1, and presented evidence that intraduodenal (ID) injection of this bacteria affected autonomic nerves and lowered blood pressure (BP) in anesthetized rats. In the study presented here, we examined the feeding, autonomic and cardiovascular effects of the lactobacillus strain...

The objective of this study was to investigate the cultivable Lactobacillus population in adult and infant faecal material to identify strains shared across a number of individuals. A range of lactobacilli isolated on Lactobacillus-selective agar from faeces of 16 infants and 11 adults were genetically fingerprinted and further characterized by 16S rRNA gene sequencing. The relatedness of all t...

Reducing the burden of pathogenic mutans streptococci is a goal of oral health. Lactobacillus paracasei DSMZ16671, even after heat-killing, specifically co-aggregates mutans streptococci in vitro and retains this activity in human saliva. In rats, it reduces mutans streptococcal colonization of teeth and caries scores. This pilot study sought to assess the potential of heat-killed L. paracasei ...

Robust genotyping methods for Lactobacillus casei are needed for strain tracking and collection management, as well as for population biology research. A collection of 52 strains initially labeled L. casei or Lactobacillus paracasei was first subjected to rplB gene sequencing together with reference strains of Lactobacillus zeae, Lactobacillus rhamnosus, and other species. Phylogenetic analysis...

Background Allergies are becoming a serious health burden in developed countries. Increasing numbers of clinical trials and animal experiments show that probiotics are new promising tools in allergy prophylaxis. In the present work we compared anti-allergic properties of the recently described probiotic mixture of Lactobacillus casei LOCK0900, L. casei LOCK0908 and L. paracasei LOCK0919 and L. ...

Various foods may be used to deliver probiotic bacteria into the gastrointestinal tract; one such example is Requeijão, a Portuguese whey cheese. Survival and stability of Bifidobacterium animalis strains BLC-1, Bb-12, and Bo, Lactobacillus acidophilus strains LAC-1 and Ki, L. paracasei ssp. paracasei strain LCS-1 and L. brevis strain LMG 6906 inoculated into Requeijão, when exposed to simulate...

In this study the effect of bean tempeh on the growth of Bacillus subtilis, Escherichia coli, Lactobacillus acidophilus and Lactobacillus paracasei bacteria was investigated. Antibacterial activity was observed only in relation to the bacteria Bacillus subtilis. The effect of tempeh products on human intestinal microflora was also assessed. Bean and soy tempeh were culinarily processed and next...

A total of 330 lactic acid bacteria isolated from South African red wines during alcoholic and malolactic fermentations and 9 commercial malolactic bacteria starter cultures were screened for antimicrobial activity. Of the entire screened isolates, 26 strains, belonging to the species Lactobacillus plantarum, Lactobacillus paracasei, Lactobacillus hilgardii and Oenococcus oeni, showed activity ...
