Which Taxo disc is used for the presumptive identification of Streptococcus pneumoniae?
Taxo P Disc (Optochin). Each disc contains approximately 5.0 g of ethyl hydrocuprein hydrochloride. Taxo P tests are presumptive. Positive tests should be followed with confirmatory tests. (See product insert for more detail). Note: Customers should not confuse these discs with the Sensi-Discs for Penicillin, which also have a P on them (Penicillin discs also have a 2 or a 10, ex. P10, P2).
