At the Veterans Affairs hospital in Pittsburgh, officials say the number of infections with a virulent bacterium known as methicillin-resistant Staphylococcus aureus, or MRSA, dropped to 17 cases last year from an average of 60 before the program started.

Focusing on MRSA and another virulent bacterium, vancomycin-resistant enterococcus, the study found no significant difference in infection and colonization rates between intensive care units that tested patients as a matter of course and those that did not.

The good news comes with a puzzling caveat: a carefully controlled study published in the same issue of the journal found that swabs and special protections like clean gloves and gowns and hand hygiene were "not effective" in reducing the transmission of MRSA or another virulent bacterium in 10 intensive care units at major medical centers.
