title: Speciation of viridans streptococci & their significance in human infections.
abstract: Sixty strains of viridans streptococci recovered, from various infections, encountered in a large referral Hospital in Tamil Nadu (south India) from December 1983 to May 1985 were characterised by conventional tests. Of these, 57 (95%) belonged to four species viz., Sanguis II, Mitis, Intermedius and Constellatus. Of the 40 strains that were assessed for their clinical significance, 23 (57.5%) were found to be either significant or of suggestive significance. The study suggested viridans streptococci are not particularly virulent pathogens. But local/systemic factors were found to predispose the subjects to this infection.
