How do you test for streptococcal pharyngitis?

Clinicians need to use either a rapid antigen detection test (RADT) or throat culture to confirm group A strep pharyngitis. RADTs have high specificity for group A strep but varying sensitivities when compared to throat culture. Throat culture is the gold standard diagnostic test.

Does strep Viridans cause pharyngitis?

Fever may persist for days, even though blood culture results rapidly become negative. Other findings include flushing, chills, stomatitis, and pharyngitis. The species usually implicated in this syndrome include S.

Identification. Viridans streptococci can be differentiated from Streptococcus pneumoniae using an optochin test, as viridans streptococci are optochin-resistant; they also lack either the polysaccharide-based capsule typical of S. pneumoniae or the Lancefield antigens of the pyogenic members of the genus.

How do you get viridans streptococcus?

Viridans streptococci are part of a normal oral flora and generally gain access to the bloodstream through breaches in the oral mucosa (in dental surgical procedures, for example).
