GAL and infection: However, while there was a significant difference between the HF-SCWP reactivities from the non-infection- associated type strain Bc ATCC 14579 and Ba CDC684 (p <0.05), there was no significant reactivity difference between dairy isolate Bc ATCC 10987 and the highly attenuated, Gal-substitution negative Ba CDC684 strain (p = 0.24).
