Non-group A beta-hemolytic streptococcal cellulitis. Association with venous and lymphatic compromise.
Cellulitis occurring in the limbs of patients who have previously undergone saphenous venectomy and coronary bypass surgery has been the subject of several recent reports. Although isolation of pathogenic microorganisms from these lesions has been uncommon, this report describes three patients who had undergone venectomy previously and in whom non-group A beta-hemolytic streptococci were recovered either during acute episodes of cellulitis or during quiescent intervals. There are to date only four other reported cases of post-venectomy cellulitis from which beta-hemolytic streptococci were isolated: one was non-group A and the others were not serologically characterized. Moreover, studies in patients without bypass who have experienced cellulitis in extremities with compromised venous and/or lymphatic circulation have also yielded a substantial number of non-group A streptococci. The data thus far implicate non-group A beta-hemolytic streptococci as a major cause of cellulitis, especially in the setting of circulatory compromise.
