Case ReportsClinical characteristics of Raoultella ornithinolytica bacteremia: a case series and literature review.
Raoultella ornithinolytica is a rare pathogen in human infection and bacteremic cases had been scarcely reported. For further comprehension of the rare infection, we summarized clinical characteristics of 6 cases that were detected at our medical facility and 5 cases from previous literature. ⋯ The prognosis of the patients was quite satisfactory. Bacterial identification in this report was performed on the basis of biochemical tests alone, and further investigations by molecular analysis are required to confirm our findings.

Antibiotic susceptibility survey of blood-borne MRSA isolates in Japan from 2008 through 2011.
We conducted an antibiotic susceptibility survey of 830 blood-borne methicillin resistant Staphylococcus aureus collected from nationwide hospitals in Japan over a three-year period from January 2008 through May 2011. Antibiotic susceptibility was judged according to the criteria recommended by the Clinical Laboratory Standard Institute. Over 99% of the MRSA showed to be susceptible to teicoplanin, linezolid, sulfamethoxazole/trimethoprim and vancomycin, and over 97% of them were susceptible to daptomycin, arbekacin and rifampin. ⋯ Unexpectedly, among the 54 hVISA and 55 BIVR, 45 isolates (83.3% and 81.8%, respectively) showed both hVISA and BIVR phenotypes. A new trend of vancomycin resistance found in this study was that VISA strains were still prevalent among the bacteremic specimens. The high rates of the hVISA/BIVR two-phenotypic vancomycin resistance, and the prevalence of VISA in the bloodborne MRSA call attention in the MRSA epidemiology in Japan.
