a
Colony morphology (sm/do, small and domed; la/fl, large and flat) and hemolytic activity were determined on BG blood agar without or with modulating (mod) agents (nicotinic acid and MgSO4).
b
Motility was determined in SS soft agar medium.
c
FHA expression was determined in supernatants by hemagglutination (the titer is expressed as the maximal dilution at which positive hemagglutination was detected).
d
Activities were determined with miniature bacterial identification strips (API 20E).
e
Browning activity was assessed on tyrosine agar plates.
f
ND, not done.
g
PR1 and PR2, patients 1 and 2 described in the present report, respectively.
