Abstract Products containing beneficial bacteria for humans have been widely used recently. The in these products generally belong to the genus Lactobacillus. Among species of this genus, Lactobacillus casei attracts a lot interest due their valuable properties. With properties, many L.casei strains can be as probiotics. Based on recommendation FAO/WHO probiotic bacteria, our study strain LC 30...

AIM The aim of this study was to evaluate the antibacterial effects of different one-step and two-step self-etching primer/adhesives on Streptococcus mutans (S. mutans), Lactobacillus casei (L. casei), and Lactobacillus acidophilus (L. acidophilus). METHODS AND MATERIALS The antibacterial effects of Clearfil Protect Bond Primer and Bonding agent; AdheSE Primer and Bonding agent; Adper Prompt ...

background: the adjuvanticity potential of lactobacillus casei was first suggested in an old survey. the present study was designed to investigate the efficacy of a new immunotherapy against breast cancer made by mixing an extract of heated 4t1 mammary carcinoma cell line and a heat-killed preparation of lactobacillus casei. methods: female balb/c mice (6–8 weeks old, n=40) were challenged subc...

The aim of this study was to compare the antagonistic properties of Lactobacillus casei GG exerted in vitro against Salmonella typhimurium C5 in a cellular model, cultured enterocyte-like Caco-2 cells, to those exerted in vivo in an animal model, C3H/He/Oujco mice. Our results show that a 1-h contact between the invading strain C5 and either the culture or the supernatant of L. casei GG impeded...

In this report, we present a draft sequence of the genome of Lactobacillus rhamnosus strain 2166, a potential novel probiotic. Genome annotation and read mapping onto a reference genome of L. rhamnosus strain GG allowed for the identification of the differences and similarities in the genomic contents and gene arrangements of these strains.

Los microorganismos ácido lácticos poseen un efecto benéfico en el engorde de los cuyes, al mejorar la degradación materia orgánica y prevenir salmonelosis. El objetivo fue evaluar microrganismos acido levaduras como suplemento las raciones para cuyes (Cavia porcellus) Ayacucho. Se activaron bacterias caldo lactosado a 37°C por 48 horas anaerobiosis, través diluciones consecutivas se sembró aga...

Pharmaceutical probiotics have been used as alternative treatments or preventative therapies for a variety of clinical diseases. The overuse of antibiotics and emergence of multiple-antibiotic resistant pathogens has refocused clinical attention on the field of probiotics. Anaerobic infections which seem to respond well to probiotics are infections which involve the disruption of normal microbi...

The elucidation of the structure of pteroylglutamic acid (PGA) (Lactobacillus casei factor, vitamin B,) has shown that p-aminobenzoic acid (PABA) is a component of the PGA molecule (1). Since earlier work has treated PABA and PGA as distinct growth factors for bacteria (2), it is now necessary to study the relationship in the utilization of these substances by bacteria. It has been shown that m...

BACKGROUND To analyse the scientific evidence that exists for the advertising claims made for two products containing Lactobacillus casei and Bifidobacterium lactis and to conduct a comparison between the published literature and what is presented in the corporate website. METHODS Systematic review, using Medline through Pubmed and Embase. We included human clinical trials that exclusively me...
