We subtyped 117 Vibrio vulnificus isolates from 85 V. vulnificus sepsis patients and 32 environmental samples by performing automated ribotyping for the purpose of molecular epidemiological study. Although there was one indistinguishable ribotype among the four human isolates and one environmental isolate, taken as a whole, the ribotypes were highly diverse regardless of sample sources. We repo...

Integron carriage by 36 epidemiologically unrelated Acinetobacter baumannii isolates collected over an 11-year period from patients in six different Italian hospitals was investigated. Sixteen type 1 integron-positive isolates (44%) were found, 13 of which carried the same array of cassettes, i.e., aacC1, orfX, orfX', and aadA1a. As ribotype analysis of the isolates demonstrated a notable genet...

We determined the PCR ribotypes and antimicrobial susceptibility patterns of 508 toxigenic Clostridium difficile isolates collected between 2011 and 2013 from 32 U.S. hospitals. Of the 29 PCR ribotypes identified, the 027 strain type was the most common (28.1%), although the rates varied by geographic region. Ribotype 014/020 isolates appear to be emerging. Clindamycin and moxifloxacin resistan...
