the objective of this study ware to investigate the effects of different doses of origanum vulgare on the growth of lactobacillus casei and lactobacillus paracasei (separated from iranian dairy products) in milk produced at one step. the product was then examined in terms of ph, acidity and microbe counting during incubator setting period. in the milk samples with lactobacillus casei, the contr...

A total of 109 lactic acid bacteria isolated from infant faeces were identified by partial 16S rRNA, cpn60 and/or pheS sequencing. Lactobacillus was the most prevalent genus, representing 48% of the isolates followed by Enterococcus (38%). Lactobacillus gasseri (21%) and Enterococcus faecalis (38%) were the main species detected. A further selection of potential probiotic starter cultures for f...

Objective. To investigate the effects of Lactobacillus acidophilus NCFM / Bifidobacterium lactis BL-04 / fructooligosaccharide and Lactobacillus plantarum LP01/ Lactobacillus paracasei LPC00 / fructo-oligosaccharide preparations in the routine clinical management of seasonal allergic rhinitis (SAR) and perennial allergic rhinitis (PAR), respectively. Materials and Methods. Seventy-six and fifty...

Probiotics have been described as a potential strategy to control opportunistic infections due to their ability to stimulate the immune system. Using the non-vertebrate model host Galleria mellonella, we evaluated whether clinical isolates of Lactobacillus spp. are able to provide protection against Candida albicans infection. Among different strains of Lactobacillus paracasei, Lactobacillus rh...

Probiotics can prevent pathological bacterial translocation by modulating intestinal microbiota and improving the gut barrier. The aim was to evaluate the effect of a fermented milk containing Lactobacillus paracasei subsp. paracasei CNCM I-1518 on bacterial translocation in rats with carbon tetrachloride (CCl4)-induced cirrhosis. Sprague-Dawley rats treated with CCl4 were randomized into a pro...

The gene encoding the cell-envelope-associated proteinase of Lactobacillus paracasei subsp. paracasei NCDO 151 (formerly Lactobacillus casei NCDO 151) was cloned and sequenced. The gene was located on the chromosome and encoded a polypeptide of 1902 amino acids. The proteinase is N-terminally cleaved upon maturation. It shows extensive homology to the Lactococcus lactis subsp. cremoris Wg2 prot...

An immunocompetent patient recovering from gallstone-induced pancreatitis had to be readmitted due to abdominal pain, fever, and rapid deterioration. Computed tomography guided needle aspiration established the diagnosis of pancreatic necrosis infection; microbiological investigations revealed monoinfection with Lactobacillus paracasei subspecies tolerans. To our knowledge, this is the first de...

The objective of this study was to develop vaginal suppository containing lactobacillus. Four kinds of vaginal suppositories containing Lactobacillus paracasei HL32 were formulated: 1) a conventional suppository with Witepsol H-15 as a base, 2) a conventional suppository with mixed polyethylene glycols (PEGs) as a base, 3) a hollow-type suppository with Witepsol H-15 as a base and 4) a hollow-t...

The aim of this study was to investigate the impact of consuming dairy yogurt containing Lactobacillus paracasei ssp. paracasei (L. paracasei), Bifidobacterium animalis ssp. lactis (B. lactis) and heat-treated Lactobacillus plantarum (L. plantarum) on immune function. A randomized, open-label, placebo-controlled study was conducted on 200 nondiabetic subjects. Over a twelve-week period, the tes...

In this study, investigations into the 23S-5S rRNA intergenic spacer regions (ISRs) of the Lactobacillus casei group were performed. A 1.6 kb fragment, from Lactobacillus paracasei strain ATCC 27092, containing part of the 5S rRNA gene (60 bp), the 5S-23S spacer region (198 bp) and part of the 23S rRNA gene (1295 bp) was cloned and sequenced (GenBank no. AF098107). This fragment was used as a p...
