a
+, present; −, absent.
b
Experimental strain numbers (1 through 22) correspond to lane designations in Fig. 3 and 4. Asterisks indicate strains for which the toxRS sequence was submitted to the DDJB/EMBL/GenBank databases. For strains isolated from international travelers (Int. travel.), the travelers' origins are shown in parentheses, as follows: THA, Thailand; SING, Singapore; MVD, the Maldives.
c
International traveler(s) arriving at Osaka Airport, Osaka, Japan.
d
International traveler(s) arriving at Kansai Airport, Osaka, Japan.
e
UT, untypeable.
