Erucic acid utilization by Lactobacillus johnsonii N6.2

Published in Frontiers in Microbiology

A multivariate nutritional analysis indicated that the consumption of erucic acid-rich food, a fatty acid (FA) found primarily in rapeseed and mustard oil, was positively correlated with higher counts of lactic acid bacteria (LAB). Furthermore, we showed Lactobacillus johnsonii N6.2, as well as other species of LAB tested from the former Lactobacil...

Genomic analysis and functional properties of Lactobacillus johnsonii GJ231 isolated from healthy beagles

Published in Frontiers in Microbiology

Probiotics are one of the management tools to improve the host’s healthy microbiota. The positive effects of probiotics on host health are species-specific, so probiotics isolated from host’s own gut may be most beneficial. Many of the metabolites (e.g., short-chain fatty acids, bacteriocins, and hydrogen peroxide) produced by Lactobacillus johnson...

Lactobacillus johnsonii is a dominant Lactobacillus in the murine oral mucosa and has chitinase activity that compromise...

Published in mBio

The interactions between the opportunistic pathogen Candida albicans and resident oral bacteria are particularly crucial in maintaining oral health. Emerging antifungal drug-resistant strains, slow-paced drug discovery, and the risk of side effects can compromise the effectiveness of current treatments available for oropharyngeal candidiasis. This ...

Protective effects of engineered Lactobacillus johnsonii expressing bovine granulocyte-macrophage colony-stimulating fac...

Published in Frontiers in Veterinary Science

Introduction Postpartum endometritis is a prevalent reproductive disorder in bovines, leading to a prolonged open period, infertility, and other complications. While Lactobacillus strains can mitigate these conditions by reducing uterine inflammation, their effectiveness is limited due to a lack of direct anti microbial action and extended treatmen...

Draft genome assembly of Lactobacillus johnsonii UMB3423 from a voided urine sample

Published in Microbiology Resource Announcements

While the urogenital microbiota of asymptomatic females is often dominated by species of Lactobacillus, Lactobacillus johnsonii is not a common member. It is more frequently found in the gastrointestinal tract. Here, we present the draft genome sequence of L. johnsonii UMB3423, which was isolated from a voided urine sample.

Lactobacillus johnsonii Improves Intestinal Barrier Function and Reduces Post-Weaning Diarrhea in Piglets: Involvement o...

Probiotic intervention is a well-established approach for replacing antibiotics in the management of weaning piglet diarrhea, which involves a large number of complex systems interacting with the gut microbiota, including the endocannabinoid system; nevertheless, the specific role of the endocannabinoid system mediated by probiotics in the piglet i...

Lactobacillus johnsonii and host communication: insight into modulatory mechanisms during health and disease

Published in Frontiers in Microbiomes

Lactobacillus johnsonii is a commensal bacterium that has been isolated from vaginal and gastrointestinal (GI) tracts of vertebrate hosts, including humans, rodents, swine, and poultry. Lactobacillus-based probiotic supplements are popular because of the health advantages they offer. Species such as L. johnsonii are particularly interesting due to ...

Lactobacillus johnsonii LJO02 (DSM 33828) Cell-Free Supernatant and Vitamin D Improve Wound Healing and Reduce Interleuk...

Methicillin-resistant biofilm-forming Staphylococcus spp. are found in about 25% of the overall cases of chronic wounds, which can undergo malignant degeneration and be associated with skin cancer. Although antimicrobial agents are clinically used to counteract pathogens and promote wound healing, they are increasingly ineffective against multi-dru...
