The concentration of cefazolin in all samples was assessed in a blinded manner with a microbiologic plate assay performed in triplicate, using plates seeded with Streptococcus sanguis
5-100 [micro]g/ml for Streptococcus mutans, Streptococcus sobrinus, Streptococcus cricetus, Streptococcus salivarius, Streptococcus sanguis
, Streptococcus oralis, Streptococcus mitis, Streptococcus gordonii, Lactobacillus casei and S.
The purpose of the study was to determine if Streptococcus sanguis
, the most common form of germ plaque would adhere to damaged endothelial cells.
gingivalis (42%) and Streptococcus sanguis
(12%), were identified in the periphery of atherosclerotic plaques by immunologic stain (65).
Frank Macrina at the Medical College of Virginia campus to determine the genetic blueprint for Streptococcus sanguis
Herzberg of the University of Minnesota in Minneapolis reported that injecting rabbits with one strain of Streptococcus sanguis
, a bacterium found in plaque, caused heart abnormalities.
A team of University of Rochester scientists is using the technique of Raman spectroscopy to study two common dental plaque bacteria, Streptococcus sanguis
The antimicrobial effect was tested in agar dilution assay in blood agar plates with Candida albicans, Streptococcus mutans, Streptococcus sanguis
, Streptococcus mitis, Streptococcus salivaruis and Actinomyces naeslundii as test organisms.
Macelignan also possessed preferential activity against other oral microorganisms such as Streptococcus sobrinus, Streptococcus salivarius, Streptococcus sanguis
, Lactobacillus acidophilus and Lactobacillus casei in the MIC range of 2-31.
Pexiganan was active against almost all species of the gram-positive microbes at less than or equal to 16 microgram/mL, and active against Streptococcus sanguis
at less than or equal to 64 microgram/mL and Enterococcus faecalis at less than or equal to 128 microgram/mL.
This well-studied recognition system comprises a carbohydrate on Streptococcus sanguis
and a lectin on Actinomyces viscosus.
Other oral bacteria such as Streptococcus sanguis
, Actinomyces and Lactobacillus species are also associated with root surface and fissure caries (Loesche, 1986, Ximenez-Fyvie, 1999).
