Pseudo-outbreak of Rhizobium radiobacter infection resulting from laboratory contamination of saline solution.

We report a pseudo-outbreak of Rhizobium radiobacter infections resulting from contamination by a saline dispenser in the microbiology laboratory. Isolates from clinical specimens had identical antimicrobial susceptibilities and electrophoretic fingerprints. The episode resolved with autoclaving of the dispenser.

Community-acquired methicillin-resistant Staphylococcus aureus infection in Singapore is usually "healthcare associated".

Objective: To assess the frequency of community-acquired methicillin-resistant Staphylococcus aureus (MRSA) infections.
