TALDO1 and infection: A similar expression profile (4 fold) of omcB was observed between 2 and 12 hpi in cells infected with serovar E. Some of the genes in response to serovar infection could not be expressed at 2 (strain L2: tal), 12 (strain L2: inc B, tal, omcB; serovar E: hctA; US151: tal, omcB), 24 (serovar E: omcB; US151: tal, omcB), 36 (serovar E: incB, pyk-F, tal, hctA, omcB; US151: tal, omcB), 48 hours post-infection (strain L2: tal, hctA, omcB; serovar E: tal; US151: htcA) using qPCR.
