Group C streptococci (GCS) and group G beta-haemolytic streptococci (GGS) have caused well-documented epidemics of acute pharyngitis in children, but the importance of these organisms in causing endemic or sporadic pharyngitis is uncertain. The heterogeneity of GCS and GGS may obscure the role of...
The spread of GAS is aided by bacterial toxins and enzymes (eg, lipase, hyaluronidase, collagenase, streptokinase), interactions among organisms (synergistic infections), local tissue factors (eg, decreased blood and oxygen supply), and general host factors (eg, immunocompromised state, chronic ...
Of 6,694 throat cultures, 2,243 (34%) yielded B-hemolytic streptococci, 83 percent (1,783) of which were bacitracin-sensitive and presumptive group A organisms. A random selection of 279 of the 460 bacitracin-resistant streptococci yielded 56 group C, 42 group G, 35 group F, 2 group A...
Eikenella corrodens and group C streptococci have been noted to occur with increased frequency in patients with underlying malignancies and immunosuppressive states. We report a case where these organisms were isolated from a patient with immunoblastic lymphadenopathy and discuss the possible association ...
Fully synthetic group A streptogramins tested for inhibitory activity against 20 strains of bacteria (see Extended Data Figs. 3, 4). Extended Data Fig. 3 Inhibitory activity against Gram-positive organisms. MIC values for selected analogues against an expanded panel of Gram-positive pathogens. So...
Use of model organisms and in vitro techniques relevant to developmental biology and medicine are acceptable, as are translational human studies.doi:10.1203/00006450-197704000-00772Davis, Jeffrey PGutman, Laura THiggins, Mary VWilfert, Catherine M...
Groups C and G streptococci also cause skin and soft-tissue infections. These organisms can colonize the skin and gain access to subcutaneous tissues after a break in skin integrity. As with S. pyogenes, lymphangitis can complicate superficial infections caused by groups C and G organisms. Musc...

Although these organisms are normally found as oral bacterial flora, entry into the bloodstream can lead to fever and embolic events. Group C streptococci (S. equisimilis, S. zooepidemicus, S. equi, S. dysgalactiae) primarily cause diseases of animals and pose little threat to immunocompetent ...
The impact of these organisms on short-term and long-term outcomes are for the most part unknown. Given that transient colonization/infection with respiratory viruses has been shown to produce short term deleterious effects either through direct pathogenesis or indirectly through resident microflora, so...
