three new species of the genus peptostreptococcus isolated from humans: peptostreptococcus vaginalis sp. nov., peptostreptococcus lacrimalis sp. nov., and peptostreptococcus lactolyticus sp. nov.we describe three new species of the genus peptostreptococcus which were isolated from human specimens and were tentatively identified as peptostreptococcus prevotii. these three organisms were not homologous with previously described type strains of the genus peptostreptococcus. a total of 12 strains that were identified biochemically as p. prevotii were divided into five independent dna similarity groups; 10 of these strains were divided into three similarity groups which exhibited significant ...19921390111
rapid identification of gram-positive anaerobic coccal species originally classified in the genus peptostreptococcus by multiplex pcr assays using genus- and species-specific primers.here, a rapid and reliable two-step multiplex pcr assay for identifying 14 gram-positive anaerobic cocci (gpac) species originally classified in the genus peptostreptococcus (anaerococcus hydrogenalis, anaerococcus lactolyticus, anaerococcus octavius, anaerococcus prevotii, anaerococcus tetradius, anaerococcus vaginalis, finegoldia magna, micromonas micros, peptostreptococcus anaerobius, peptoniphilus asaccharolyticus, peptoniphilus harei, peptoniphilus indolicus, peptoniphilus ivorii and pepton ...200312855723
peptostreptococcus vaginalis or peptostreptococcus prevotii? identification and clinical importance of a new species of peptostreptococcus.peptostreptococcus vaginalis is a recently described species of gram-positive anaerobic coccus. we report one case in which p. vaginalis was isolated in pure culture from an abscess on the upper arm, and summarise nine further cases where it was isolated in mixed culture from other superficial sites, particularly infected leg ulcers. we suggest that clinical strains of p. vaginalis have probably been described in the past as peptostreptococcus prevotii, a species which has frequently been report ...199716887558
development of 16s rrna-based probes for the identification of gram-positive anaerobic cocci isolated from human clinical specimens.fluorescent probes targeted at 16s rrna were designed for peptostreptococcus anaerobius and peptostreptococcus stomatis (pana134), parvimonas micra (pamic1435), finegoldia magna (fmag1250), peptoniphilus asaccharolyticus (pnasa1254), peptoniphilus ivorii (pnivo731), peptoniphilus harei (pnhar1466), anaerococcus vaginalis (avag1280) and anaerococcus lactolyticus (alac1438), based on the 16s rrna sequences of reference strains and 88 randomly chosen clinical isolates. these strains were also used ...200717714522
identification of gram-positive anaerobic cocci by maldi-tof mass spectrometry.gram-positive anaerobic cocci (gpac) are part of the commensal microbiota of humans and are a phylogenetically heterogeneous group of organisms. to evaluate the suitability of matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (maldi-tof ms) for the identification of gpac, a database was constructed, using reference strains of commonly encountered gpac and clinical isolates of which the sequence of the 16s rrna gene was determined. subsequently, the database was validat ...201121292417
proposal of the genera anaerococcus gen. nov., peptoniphilus gen. nov. and gallicola gen. nov. for members of the genus peptostreptococcus.members of genus peptostreptococcus have previously been found to be distantly related to the type species, peptostreptococcus anaerobius, on the basis of 16s rdna sequence similarities. they were divided into three major phylogenetic groups, and their peptidoglycan structure and biochemical traits differed between groups. the reclassification of the species of these three groups into three new genera, peptoniphilus gen. nov., anaerococcus gen. nov. and gallicola gen. nov., is proposed. the genu ...200111491354
