An analytical system based on rRNA-targeted reverse transcription-quantitative PCR (RT-qPCR) was established for the precise evaluation of human intestinal microbiota. Group- and species-specific primer sets for Clostridium perfringens, Lactobacillus spp. (six subgroups and three species), Enterococcus spp., and Staphylococcus spp. targeting 16S rRNA gene sequences were newly developed for the ...
In this study we evaluated alteration of intestinal microflora by terminal-restriction fragment length polymorphism (T-RFLP) analysis and quantitative PCR (qPCR) for specific microbes. The effects of orally administered heat-killed Lactobacillus pentosus strain b240 (HK-b240) in immunosuppressed mice with endogenous Pseudomonas aeruginosa sepsis was estimated. By T-RFLP analysis, 5 dominant ope...
Background and purpose: Probiotics and prebiotics are new concepts which have been demonstrated to positively modulate the intestinal micro flora and could promote host health. The aim of this study was to evaluate the effects of prebiotics on production of antimicrobial properties of Lactobacillus acidophilus ATCC4356 ، Lactobacillus plantarum ATCC 8014 Lactobacillus fermentum ATCC 9338 La...
The inability of two Lactobacillus strains to ferment D-xylose was complemented by the introduction of Lactobacillus pentosus genes encoding D-xylose isomerase, D-xylulose kinase, and a D-xylose catabolism regulatory protein. This result opens the possibility of using D-xylose fermentation as a food-grade selection marker for Lactobacillus spp.
Spacer region between 16S and 23 S rRNA genes of thirteen lactic acid bacteria strains from Burkina Faso fermented milk samples were amplified by the polymerase chain reaction (PCR). Lactobacillus delbrueckii, Lactobacillus acidophilus, Lactobacillus fermentum, Streptococcus thermophilus, Pediococcus spp, Leuconostoc mesenteroides subsp mesenteroides were identified. The Lactobacillus group was...
A residual inhibitory effect on microbial growth due to modified-atmosphere (MA) storage (MA, 80% CO2-20% air) was demonstrated for rock cod fillets stored in MA and transferred to air at 4 degrees C. Results of measurements of CO2 concentrations of the fillets suggested that the residual effect after transfer from MA to air was not due to retention of CO2 at the surface of the fillets but was ...
This study aimed at the antibody production by intestinal mucosa of broilers chicks were orally inoculated with Lactobacillus spp. at one and/or 21 days of age, and subsequently challenged with Salmonella enterica, subspecies enterica, serotype Enteritidis (S. Enteritidis). A total number of 288 drug-free broiler chicks was divided into 6 groups (groups A, B, C, D, E, and F), according to age a...
Pathogens in the gastrointestinal tract exist within a vast population of microbes. We examined associations between pathogens and composition of gut microbiota as they relate to Shigella spp./enteroinvasive Escherichia coli infection. We analyzed 3,035 stool specimens (1,735 nondiarrheal and 1,300 moderate-to-severe diarrheal) from the Global Enteric Multicenter Study for 9 enteropathogens. Di...
The aim of this study was to determine the influence of oral hygiene instruction (OHI) on oral hygiene status and on the reduction of inducing bacteria (Streptococcus mutans and Lactobacillus spp.) in 30 subjects (12 males and 18 females) with an age range from 10 to 14 years. The patients were instructed on how to carry out effective oral hygiene close to brackets and ligatures, and in the use...
