Three strains of lactobacilli, Lactobacillus casei subsp. casei 64H, L. casei subsp. rhamnosus OC91, and L. coryniformis M34, were examined for the presence of plasmids. Plasmids of molecular weights of 23 x 10(6) and 16 x 10(6) were found in the first two strains respectively. This represents the first evidence for plasmids in lactobacilli; their function is not presently known.

Lactobacilli are low-virulence, commensal organisms of the gastrointestinal and genitourinary tracts and are commonly used as "probiotic supplements." Herein, we describe an episode of respiratory syncytial virus (RSV) bronchiolitis with bacterial superinfection secondary to administration of Lactobacillus rhamnosus in an 11-month-old female with trisomy 21.

Normal-gravity (22 to 24 degrees Plato) wheat mashes were inoculated with five industrially important strains of lactobacilli at approximately 10(5), approximately 10(6), approximately 10(7), approximately 10(8), and approximately 10(9) CFU/ml in order to study the effects of the lactobacilli on yeast growth and ethanol productivity. Lactobacillus plantarum, Lactobacillus paracasei, Lactobacill...

AIMS Probiotic milk-based formulations were spray-dried with various combinations of prebiotic substances in an effort to generate synbiotic powder products. METHODS AND RESULTS To examine the effect of growth phase and inclusion of a prebiotic substance in the feed media on probiotic viability during spray-drying, Lactobacillus rhamnosus GG was spray-dried in lag, early log and stationary ph...

We investigated the impact of probiotics on the intestinal carriage of vancomycin-resistant enterococci (VRE). Administration of Lactobacillus rhamnosus Lcr35 but not Escherichia coli Nissle reduced, although not significantly, the density of VRE colonization in a murine model. No effect of Lcr35 was observed in a double-blind placebo randomized study, involving nine patients.

We report a case of meningitis due to Lactobacillus rhamnosus in a child undergoing allogeneic hematopoietic stem cell transplantation for acute leukemia. Four episodes of bacteremia involving strains with pulsotypes identical to that of the cerebrospinal fluid isolate preceded meningitis. After several courses of clindamycin, no relapse occurred during the patient follow-up.

Here we report the draft genomic sequences of two clinical isolates of Lactobacillus rhamnosus from infected dental pulps representing the initial stages of infection of pulp tissue. Based on 454 FLX+ pyrosequencing, the two clinical isolates infecting vital pulp had a genome length of 2.9 Mbp with distinct genomic signatures.

The diversity and dynamics of Lactobacillus populations in traditional raw milk Camembert cheese were monitored throughout the manufacturing process in 3 dairies. Culture-dependent analysis was carried out on isolates grown on acidified de Man - Rogosa - Sharpe agar and Lactobacillus anaerobic de Man Rogosa Sharpe agar supplemented with vancomycin and bromocresol green media. The isolates were ...
