Characterization of probiotic Lactobacillus spp. isolates from commercial fermented milks
… the right medium for enumeration of probiotic Lactobacillus. Based on selectivity of medium for recovery of the targeted lactobacilli and also simplicity of preparation, MRS-Clindamycin was chosen as the best medium for enumeration of probiotic Lactobacillus in fermented milks. The results of …

Evaluation of Pectin Methylesterase and Lactobacillus spp. Isolated from Tabasco Peppers (Capsicum frutescens L.)
… plant. All samples showed the presence of Lactobacillus as indicated by PCR. Quantitative real-time polymerase chain reaction (QRT-PCR) was employed to quantify total bacteria and lactobacilli in the samples. The percentage share of Lactobacillus in the counts was higher in 36-month aged …

Reduction of Campylobacter jejuni on Chicken Wingettes by Treatment with Caprylic Acid, Chitosan or Protective Cultures of Lactobacillus spp.
… day 0 through day 5.</p> <p>In the second study Lactobacillus spp. isolates with in-vitro anti-Campylobacter activity were evaluated for their efficacy as a protective culture when applied to chicken wingettes. An original 13 isolates of Lactobacillus were screened, resulting in the selection of …

Evaluating oxalate-degrading Lactobacillus spp. for their ability to be used as probiotics in the treatment of kidney stone disease
… it is probably a multifactorial disease. Lactobacillus strains which potentially had increased ability to degrade oxalate were previously isolated from a healthy low kidney stone risk group. The aim of this study was to identify these natural Lactobacillus strains and evaluate their …

Evaluation of probiotic and vaginal Lactobacillus species for the treatment of bacterial vaginosis and promotion of vaginal health in South African women
… it has been hypothesized that lytic or temperate Lactobacillus bacteriophages may contribute. The current standard of care for BV are antibiotics like metronidazole or clindamycin, although these are not effective long-term, as rates of BV recurrence are high. There is thus an urgent need for …

Characterizing the roles of gut microbiota, probiotic Lactobacilli and CX3CR1 in the development of autoimmunity in MRL/lpr mice
… We previously published that the mixture of Lactobacillus reuteri (L. reuteri), L. oris, L. johnsonii, L. gasseri, and L. rhamnosus significantly attenuated disease in MRL/lpr mice by restoring the imbalance between regulatory T cells and T helper-17 cells. To further understand the role of …

Intestinal delivery of heterologous peptides with lactobacilli
… protein into the gastrointestinal tract. Lactobacillus spp. are a potential delivery vehicle for oral antigens because of their generally regarded as safe (GRAS) status, ability to persist in the acidic environment of human gastrointestinal tract and also their health benefit to the host. …

The Role of Microbiota in Formation and Bioavailability of Sulforaphane From Glucoraphanin in F344 Rats
… major detectable hydrolytic product by single Lactobacillus spp. evaluated in our study was nitrile, instead of isothiocyanate. This caused by decreased pH in media, known to favor nitrile formation, since microbiota in buffer did not alter this. The technical limitation of in vitro incubation …

Controlled microbiological and environmental techniques in meat processing
… solution of each treatment indicated that a Lactobacillus spp. was predominant in the Reduced Initial Count treatment. The inoculated Pediococcus cerevisiae was predominant in the Gnotobiotic treatment, while Staphylococcus epidermidis and Flavobacterium diffusum were predominant in the …

Wirkung von Enterococcus faecium auf den Organismus neonataler Hundewelpen
… as is the discovery of a higher average count on Lactobacillus spp. in the trail group. The count on aerobe bacteria, Cl. perfringens, Enterococcus spp. and Lactobacillus spp. decreased with ongoing age of the puppies. In the period of milk-replacer feeding, probiotic feeding seemed to result in a …

Molecular structure and antibacterial function of hop resin materials
Spoilage of beer by lactic acid bacteria (Lactobacillus spp., Pediococcus spp.) has considerable economic significance. Compounds derived from the hop (Humulus lupulus) possess antibacterial activity but their role in prevention of beer spoilage has been disputed. Prior to the present study, the …

Lactobacillus strategies to reduce Campylobacter jejuni colonization of broiler chickens
… poultry supply are underdeveloped. The probiotic Lactobacillus spp. are a viable delivery vehicle for mucosal vaccines due to the Generally Recognized As Safe (GRAS) status. In addition, recombinant lactobacilli present proteins to the mucosal surface and elicit host immune responses. The overall …

Diversity of vaginal microbiota associated with bacterial vaginosis and the impact on pregnancy outcomes in HIV-infected and uninfected women.
… of protective resident microorganisms such as Lactobacillus spp. by anaerobic bacteria is known as bacterial vaginosis (BV). BV is prevalent in women of African descent and may be a cause of higher rates of adverse birth outcomes in these women. Adverse birth outcomes have been reported to be …

The role of gut microbiota in systemic lupus erythematosus
… in the gut by suppling a mixture of 5 Lactobacillus strains improved renal function of these mice and prolonged their survival. Further studies revealed that MRL/lpr mice possessed a "leaky" gut, which was reversed by increased Lactobacillus colonization. Inside the kidney, oral …

Baboon vaginal microbiota: an overlooked aspect of primate physiology
… studies have shown that Firmicutes (mostly Lactobacillus spp.) predominate in the human vagina, with Actinobacteria (Gardnerella vaginalis) and Proteobacteria present in lower numbers. By contrast, Papio baboons harbored species not only of Firmicutes but also of Fusobacteria, Bacteroidetes …

The effect of bacterial vaginosis on HIV infection
… the female reproductive tract (FRT) when optimal Lactobacillus spp. such as L. crispatus, are displaced by anaerobes such as Gardnerella spp., consistently isolated from the FRT of BV-positive women. Gardnerella spp. produce a number of important virulence factors such as vaginolysin (VLY) and …
