  1. aSemi-quantification of intensity of the 16S rDNA amplification products, visualized using ethidium bromide staining after agarose gel electrophoresis: '+' indicates barely visible band, and '++++' indicates maximal intensity. OA, osteoarthritis; RA, rheumatoid arthritis; ReA, reactive arthritis; UA, undifferentiated arthritis.
