a
Isolates ALE1, ALE2, ALE3, ALE4, CLE1, CLE2, CLE3, and CLE4 were isolated on Enterococcosel agar containing 20 μg of tetracycline per ml. All other isolates were obtained from MR2A agar containing 20 μg of tetracycline per ml.
b
No tet(W), tet(O), tet(Q), tet(T), tetB(P), or otrA was detected in any isolate.
c
Background control well located upstream of the lagoon.
