Última Bacteriocin-like activity of oral Fusobacterium nucleatum isolated from human and non-human primates Rev. Microbiol. Gaetti-Jardim Júnior,Elerson; Avila-Campos,Mario Julio. Fusobacterium nucleatum is indigenous of the human oral cavity and has been involved in different infectious processes. The production of bacteriocin-like substances may be important in regulation of bacterial microbiota in oral cavity. The ability to produce bacteriocin-like substances by 80 oral F. nucleatum isolates obtained from periodontal patients, healthy individuals and Cebus apella monkeys, was examinated. 17.5% of all tested isolates showed auto-antagonism and 78.8% iso- or hetero-antagonism. No isolate from monkey was capable to produce auto-inhibition. In this study, the antagonistic substances production was variable in all tested isolates. Most of the F. nucleatum showed antagonistic activity against tested reference strains. These data...

Fusobacterium nucleatum is considered a bridge organism between earlier and later colonizers in dental biofilms and a putative periodontopathogen. In Dentistry, antimicrobial agents are used for treatment and control of infectious diseases associated with dental plaque. Antiseptics have been used in association with antibiotics to reduce infections after oral surgeries. In this study, the influence of subinhibitory concentrations (SC) of chlorhexidine, triclosan, penicillin G and metronidazole, on hydrophobicity, adherence to oral epithelial cells, and ultra-structure of F. nucleatum was examined. All isolates were susceptible to chlorhexidine, triclosan, and metronidazole; however, most of the isolates were susceptible to penicillin G, and all of them...

Ano: 2002 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1517-83822002000200017 Partial characterization of antagonistic substance produced by a Clostridium butyricum strain BJM Caires,Nely Cristina Medeiros; Matos,Aline Magalhães; Farias,Luiz de Macedo; Carvalho,Maria Auxiliadora Roque de; Drummond,Regina Maria Nardi; Nicoli,Jacques Robert; Ribeiro Sobrinho,Antônio Paulino. The production of antagonistic substance by bacterium present in the infected root canal system (RCS) probably is an important ecological factor for its successful colonization of the local. The objective of this study was to partially characterize an antagonistic substance produced by a Clostridium butyricum isolated from infected RCS.Production of inhibitory compound was evaluated by the agar double layer diffusion technique using Fusobacterium nucleatum and Bifidobacterium adolescentis as indicator bacteria. The physicochemical and biochemical factors tested for the partial characterization were influence of pH and temperature and susceptibility to the action of some proteolytic enzymes. An inhibition zone was observed against the two indicator strains...

Ano: 2007 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1517-83822007000200014 Virulence of oral Fusobacterium nucleatum from humans and non-human primates in mice BJM Gaetti-Jardim Júnior,Elerson; Luvizotto,Maria C. Rui; Avila-Campos,Mario J.. The lethal action in Balb/c mice of 80 oral Fusobacterium nucleatum recovered from patients with adult periodontitis, healthy subjects or Cebus apella monkeys was studied. Mice were inoculated intraperitoneally with each bacterial inoculum of 5 x 10(8) CFU/ml. All the clinical isolates induced weight and coordinated movements loss. Pathological alterations in liver, CNS, heart, and kidney with inflammatory reactions or vascular congestion were observed. Of all the tested F. nucleatum isolates, 61.2% from periodontal patients, 57.1% from healthy subjects and 60% from monkeys, were capable of killing the mice in 48h. The clinical isolates were significantly more pathogenic than F. nucleatum ATCC 10953 or ATCC 25586. B. fragilis ATCC 23745 showed lethality...
