Chicks 405–408 and 505–508 are from the first experiment, while chicks 343–346 and 237–240 are from the second experiment.
aYes: plaques formed on isolated strain, No: no plaques formed on isolated strain.
bBacteria isolated from this chick showed reduced MeOPN levels (of both MeOPN groups) and enhanced levels of 6-O-Me.
cMeOPN levels barely above the baseline could be detected from bacteria isolated from this chick.
NR, not relevant.
