The purpose of this study was to analyze the in vitro antimicrobial activity of sodium hypochlorite (1% and 5%) and chlorhexidine (0.12%, 0.5% and 1%). Bacterial samples (ATCC) of Staphylococcus aureus, Enterococcus faecalis, Escherichia coli, Porphyromonas gingivalis and Fusobacterium nucleatum were submitted to a contact test. Solutions were evaluated at different time intervals: immediately,...
Despite limitations of swab transport systems (STS), many clinical samples and bacterial isolates are sent on these devices. We evaluated the performance of 4 commercial STS: M40 Transystem (S1, Copan Italia, Bovezzo, Italy), UNI-TER (S2, MEUS, Piove di Sacco, Italy), Euromed (S3, LAB SERVICE, Surbo, Italy), and Eurotubo (S4, Deltalab, Rubí, Spain). Survival of ATCC and clinical strains with ch...
Fusobacterium nucleatum is an oral pathogen that is linked to multiple human infections and colorectal cancer. Strikingly, F. nucleatum achieves virulence in the absence of large, multiprotein secretion systems (Types I, II, III, IV, and VI), which are widely used by Gram-negative bacteria for pathogenesis. By contrast, F. nucleatum strains contain genomic expansions of Type V secreted effector...
Examination of 15,844 clinical specimens submitted over 12 years (1973 to 1985) to the anaerobic microbiology laboratories in two military hospitals demonstrated the recovery of anaerobic bacteria in 4,458 (28.1%) specimens. The specimens yielded 6,557 anaerobic isolates (1.47 isolates per specimen). Bacteroides spp. accounted for 43% of all isolates; anaerobic gram-positive cocci, 26%; Clostri...
Aim. To study the correlation between intestinal flora and ulcerative colitis by analyzing the abundance of Bacteroides, Fusobacterium, Clostridium, Bifidobacterium spp., and Faecalibacterium prausnitzii in the intestinal of ulcerative colitis (UC) patients and healthy controls with Uygur and Han ethnic. Methods. Bacterial genomic DNA was extracted from fecal samples and analyzed with real-time...
Aim: The study aimed at isolation and preliminary characterization of anaerobic bacteria from a special crossbreed of Muturu and N’Dama cattle found in parts of Nigeria. Study Design: The work investigated the suitability of the isolates in in vitro fermentation of biomass and evaluated the relationship between the bacterial flora and their ability to hydrolyse lignocellulosic materials from co...
Biapenem is a carbapenem being developed in combination with RPX7009, a new inhibitor of serine β-lactamases. Biapenem was tested alone and in combination with fixed concentrations of RPX7009 by agar dilution against 377 recent isolates of anaerobes. A separate panel of 27 isolates of Bacteroides spp. with decreased susceptibility or resistance to imipenem was also tested. Comparator drugs incl...
Five subspecies of Fusobacterium nucleatum have been classified: animalis, nucleatum, polymorphum, vincentii, and fusiforme. F. nucleatum subsp. animalis ChDC F324 (KCOM 1325) was isolated from a human subgingival plaque in the Republic of Korea. Here, we report the draft genome sequence of the strain.
Fusobacterium nucleatum is a Gram-negative, nonmotile, obligately anaerobic rod bacterium which might play an important role in the initiation and progression of periodontal diseases. F. nucleatum subsp. vincentii ChDC F8 (KCOM 1231) was isolated from a human gingivitis lesion. Here, we report the draft genome sequence of the strain.
Members of our group recently identified a new tetracycline resistance gene, tet(W), in three genera of rumen obligate anaerobes. Here, we show that tet(W) is also present in bacteria isolated from human feces. The tet(W) genes found in human Fusobacterium prausnitzii and Bifidobacterium longum isolates were more than 99.9% identical to those from a rumen isolate of Butyrivibrio fibrisolvens.
