This study analysed the clinical characteristics of bacteraemia due to unusual Citrobacter species. All non-freundii and non-koseri Citrobacter isolates were identified to species level by two commercial identification methods and 16S rRNA gene sequence analysis. A total of 306 patients with Citrobacter spp. bacteraemia were identified from January 2000 through December 2009. ⋯ An attributable mortality was 33.3%. Antimicrobial susceptibility testing showed that the resistance patterns varied among different Citrobacter species. Non-freundii and non-koseri Citrobacter species are difficult to identify and are a rare cause of intra-abdominal infections with secondary healthcare-associated bacteraemia in immunocompromised patients.

Hand hygiene is considered to be the single most effective measure to prevent healthcare-associated infection. Although there have been several reports on hand hygiene compliance, data on patients with multidrug-resistant (MDR) organisms in special isolation conditions are lacking. Therefore, we conducted a prospective observational study of indications for, and compliance with, hand hygiene in patients colonised or infected with meticillin-resistant Staphylococcus aureus (MRSA) or extended-spectrum β-lactamase (ESBL)-producing enterobacteria in surgical intensive and intermediate care units. ⋯ This study is the first to provide data on hand hygiene in patients with MDR bacteria and includes a comparison of observed and calculated compliance. Compliance is low in patients under special isolation conditions, even for the indications of greatest impact in preventing healthcare-associated infections. These data may help to focus measures to reduce transmission of MDR bacteria and improve patient safety.
