BACKGROUND Probiotics may alter immune regulation. Recently, we showed that the probiotic bacteria Lactobacillus acidophilus NCFM™ influenced the activity of regulatory T cells (Tregs) in vitro. The aim of the present work was to demonstrate if L. acidophilus NCFM™ also affects the function of Tregs in vivo. METHODS Development of colitis after transfer of CD4+CD25- T cells and protection fro...
P-glycoprotein (P-gp) mediates efflux of xenobiotics and bacterial toxins from the intestinal mucosa into the lumen. Dysregulation of P-gp has been implicated in inflammatory bowel disease. Certain probiotics have been shown to be effective in treating inflammatory bowel disease. However, direct effects of probiotics on P-gp are not known. Current studies examined the effects of Lactobacilli on...
background: the effect of probiotic bacteria ( lactobacillus acidophilus and l. casei ) as safe organisms was examined on fungal growth and aflatoxin gene regulation in aspergillus parasiticus . methods: the fungus was cultured in presence of two different concentrations of l. acidophilus and l. casei in mrs broth medium. mycelia dry weight is indicated as criteria to evaluate fungal growth. be...
Lactobacillus acidophilus is a natural inhabitant of mammalian gastrointestinal systems and is used in dairy and pharmaceutical products. Five draft genome sequences, covering 1,995,790 nucleotides (nt) on average, are divided into 19 to 34 scaffolds covering 1,995 to 2,053 genes. The draft genome sequences were compared to the sequence of the L. acidophilus NCFM dairy strain.
We present the 1,991,830-bp complete genome sequence of Lactobacillus acidophilus strain La-14 (SD-5212). Comparative genomic analysis revealed 99.98% similarity overall to the L. acidophilus NCFM genome. Globally, 111 single nucleotide polymorphisms (SNPs) (95 SNPs, 16 indels) were observed throughout the genome. Also, a 416-bp deletion in the LA14_1146 sugar ABC transporter was identified.
A commercial plant extract (prepared from olive, garlic, onion and citrus extracts with sodium acetate (SA) as a carrier) was evaluated to extend the viability of yogurt starter and probiotic bacteria as a means to enhance the shelf life of live and active culture, probiotic nonfat yogurt. Yogurts prepared from three different formulas (0.5* plant extract, 0.25* SA, or no supplement) and cultur...
A lactic acid bacterium presenting antimicrobial activity against a Lactobacillus acidophilus strain used for eradication of acid inhibition was isolated from a natural cheese. The 16S rRNA gene sequence of the isolate best matched with a strain of L. rhamnosus and was designated L. rhamnosus CJNU 0519. The antimicrobial activity of the partially purified bacteriocin of CJNU 0519 was abolished ...
Lactic acid bacteria (LAB) were isolated from camel milk by culturing the milk on specific media and pure culture was obtained by sub-culturing. Purification of culture was confirmed by Gram’s staining and identified by different biochemical tests. Camel milk contained lactic acid producing bacteria like Streptococci such as S. cremoris and S. lactis and Lactobacilli such as L. acidophilus. L. ...
Here we present the complete genome sequence of Lactobacillus acidophilus ATCC 53544. The assembly contains 1,991,906 bp and is 99.7% similar to L. acidophilus NCFM. This strain was isolated from a rectal swab specimen of an infant and has previously been used as a feed supplement for animals.
In the present work, the effect of milk supplementation on viability of yogurt bacteria (Streptococcus thermophilus and Lactobacillus delbrueckii subsp. bulgaricus) and probiotic bacteria (Lactobacillus acidophilus and Bifidobacteria) was studied during yogurt manufacture and thirty three days storage. Incubation time to reach pH value of 4.5 was greatly affected by the addition of casein fract...
