| displacement of enterococcus faecalis from hydrophobic and hydrophilic substrata by lactobacillus and streptococcus spp. as studied in a parallel plate flow chamber. | the displacement of enterococcus faecalis 1131 from hydrophobic and hydrophilic substrata by isolates of lactobacillus casei 36 and streptococcus hyointestinalis km1 was studied in a parallel plate flow chamber. the experiments were conducted with either 10 mm potassium phosphate buffer or human urine as the suspending fluid, and adhesion and displacement were measured by real-time in situ image analysis. the results showed that e. faecalis 1131 was displaced by lactobacilli (31%) and streptococ ... | 1994 | 8031082 |
| characterization of enterocin- and salivaricin-producing lactic acid bacteria from the mammalian gastrointestinal tract. | bacteriocin production may be a factor contributing to bacterial dominance within complex microbial populations and may therefore be a common trait within the gut microbiota. however, of 278 antimicrobial-producing culturable lactic acid bacteria (lab) isolated from a range of mammalian intestinal sources in this study, characterization revealed just 23 distinct strains producing bacteriocin-like inhibitory substances and one streptococcus hyointestinalis strain producing a potentially novel pro ... | 2009 | 19076236 |
| streptococcus merionis sp. nov., isolated from mongolian jirds (meriones unguiculatus). | gram-positive, catalase-negative, chain-forming, coccus-shaped organisms were isolated both from intraperitoneally grown vesicles of the fox tapeworm echinococcus multilocularis and the oropharynges of laboratory-kept mongolian jirds (meriones unguiculatus). the strains displayed no haemolytic activity on columbia sheep blood agar, pyrrolidonyl arylamidase activity was negative and the organisms reacted weakly with lancefield group d antiserum. on the basis of phenotypic characteristics, the str ... | 2009 | 19329603 |
| bacteria-induced egg hatching differs for trichuris muris and trichuris suis. | eggs of the porcine whipworm trichuris suis are currently explored in human clinical trials as a treatment of immune-mediated diseases. in this context, only the infective, embryonated eggs, constitute the active pharmaceutical ingredient (api). the rodent whipworm, trichuris muris is commonly used as a laboratory model to study trichuris biology. the embryonated eggs (containing a fully developed larva) are biologically active and will invade the large intestinal mucosa of the host. this study ... | 2015 | 26174801 |
| molecular and antimicrobial susceptibility profiling of atypical streptococcus species from porcine clinical specimens. | the streptococcus species present broad phenotypic variation, making identification difficult using only traditional microbiological methods. even though streptococcus suis is the most important species for the worldwide swine industry, other streptococcus species appear to be able to cause disease in swine and could represent a higher underestimated risk for porcine health. the aim of this study was to identify streptococcus-like isolates by maldi-tof ms and 16s rrna sequencing and further mole ... | 2016 | 27491454 |
| nisin h is a new nisin variant produced by the gut-derived strain streptococcus hyointestinalis dpc6484. | accumulating evidence suggests that bacteriocin production represents a probiotic trait for intestinal strains to promote dominance, fight infection, and even signal the immune system. in this respect, in a previous study, we isolated from the porcine intestine a strain of streptococcus hyointestinalis dpc6484 that displays antimicrobial activity against a wide range of gram-positive bacteria and produces a bacteriocin with a mass of 3,453 da. interestingly, the strain was also found to be immun ... | 2015 | 25841003 |
