Origin, sequence type and antibiotic susceptibility of <i>Acinetobacter baumannii</i> from Ohio.

<p>Distribution of 122 <i>A. baumannii</i> isolates by hospital of origin (hospitals A, B, C and D), year, sequence type (ST) determined by PCR/ESI-MS, worldwide clone type (WW) and susceptibility to carbapenems and ampicillin/sulbactam.</p

Genetic similarity among <i>A. baumannii</i> isolates.

<p>Representative <i>A. baumannii</i> isolates typed by rep-PCR, analyzed with the Kullback-Leibler method. Five strain types with >95% similarity are illustrated, and further discriminated by year, hospital of origin, PCR-ESI/MS sequence type (ST), and worldwide (WW) clone types.</p
