TABLE 2.

Breakdown of the number of samples that tested positive for specific RAPD types of genotypically confirmed Klebsiella spp.

Sample typeNo. of positive samples (no. of unique RAPD types) with RAPD type:

Milk8c1646230
Linersa0501300

Feces, feed, water8 (20)201104
  • a Rubber liners of milking machine units.

  • b For milk samples, one isolate per sample was characterized, and the number of unique RAPD types equals the number of samples. For bedding, feces, feed, and water samples, multiple isolates per sample were characterized, and the number of unique RAPD types (shown in parentheses) is higher than the number of samples. RAPD types were considered to be unique if they were found in one sample only.

  • c Unique RAPD types of K. oxytoca were detected in one milk sample and in one bedding sample. All other isolates were K. pneumoniae.
