MBLs were detected in 96 (0.5\%) of the 19,753 isolates by the broth microdilution method, the 2-mercaptopropionic acid inhibition test, and PCR and DNA sequencing analyses. MBL-positive isolates were detected in 9 of 13 laboratories, with the rate of detection ranging between 0 and 2.6\% for each laboratory. Forty-four of 1,429 (3.1\%) Serratia marcescens, 22 of 6,198 (0.4\%) Pseudomonas aeruginosa, 21 of 1,108 (1.9\%) Acinetobacter spp., 4 of 544 (0.7\%) Citrobacter freundii, 3 of 127 (2.4\%) Providencia rettgeri, 1 of 434 (0.2\%) Morganella morganii, and 1 of 1,483 (0.1\%) Enterobacter cloacae isolates were positive for MBLs. Of these 96 MBL-positive strains, 87 (90.6\%), 7 (7.3\%), and 2 (2.1\%) isolates carried the genes for IMP-1-group MBLs, IMP-2-group MBLs, and VIM-2-group MBLs, respectively. The class 1 integrase gene, intI1, was detected in all MBL-positive strains, and the aac (6')-Ib gene was detected in 37 (38.5\%) isolates. Strains with identical PCR fingerprint profiles in a random amplified polymorphic DNA pattern analysis were isolated successively from five separate hospitals, suggesting the nosocomial spread of the organism in each hospital. In conclusion, many species of MBL-positive gram-negative rods are distributed widely in different hospitals in the Kinki region of Japan. The present findings should be considered during the development of policies and strategies to prevent the emergence and further spread of MBL-producing bacteria.
