Comparative pathogenicity of Actinomyces naeslundii and Actinomyces israelii.
Typical actinomycosis has been produced in mice following single intraperitoneal injections of saline suspensions of Actinomyces israelii and A. naeslundii. A. israelii produced infections in 95.8% of the animals inoculated. A. naeslundii, generally considered to be a saprophytic organism, produced lesions in 89.7% of the inoculated animals. The finding that A. naeslundii produced lesions in mi...
متن کاملIdentification of Actinomyces israelii and Actinomyces naeslundii by fluorescent-antibody and agar-gel diffusion techniques.
This study was an attempt to develop a fluorescent-antibody (FA) test to differentiate Actinomyces israelii and A. naeslundii as an aid in their laboratory identification. Two strains of A. israelii (X522 and A601) and two strains of A. naeslundii (X454 and X600), which had received intensive study by several investigators, were used for the immunization of rabbits. Working titers, based on tes...
متن کاملMannose-contaminating agglutinin for Actinomyces viscosus and Actinomyces naeslundii.
Rapid agglutination of Actinomyces viscosus and Actinomyces naeslundii cells by D-mannose solutions was observed during studies of their attachment to mammalian cells in vitro. The specificity of the agglutination reaction was studied by slide agglutination tests and by measuring the rate of decrease in optical density of bacterial phosphate buffer suspensions caused by the setting of bacterial...
متن کاملEmended description of Actinomyces naeslundii and descriptions of Actinomyces oris sp. nov. and Actinomyces johnsonii sp. nov., previously identified as Actinomyces naeslundii genospecies 1, 2 and WVA 963
Actinomyces naeslundii is an important early colonizer in the oral biofilm and consists of three genospecies (1, 2 and WVA 963) which cannot be readily differentiated using conventional phenotypic testing or on the basis of 16S rRNA gene sequencing. We have investigated a representative collection of type and reference strains and clinical and oral isolates (n=115) and determined the partial ge...
متن کاملPrimary Sternal Osteomyelitis Caused by Actinomyces israelii
Primary sternal osteomyelitis is a rare disease. Common infectious organisms causing primary sternal osteomyelitis include Staphylococcus aureus and Pseudomonas aeruginosa. Actinomyces species are common saprophytes of the oral cavity, but there have been few reports in the literature of primary sternal osteomyelitis caused by Actinomyces species. We describe a case of primary sternal osteomyel...
