NG-Test CTX-M MULTI results obtained for two urine samples and bacterial colonies of isolates from the samples. A weak CTX-M band (false-positive) was observed in direct testing of the two urine samples, (a) urine P051 and (b) urine P193. Negative results were obtained for the culture colonies of (c) Escherichia coli from P051, (d) E. coli 1 from P193 and (e) E. coli 2 from P193. Sample P193 was culture-positive for two different E. coli. C stands for the control line, and T for the CTX-M test line.
