The transfer of gram-positive bacteria, particularly multiresistant
Staphylococcus aureus (MRSA) and vancomycin-resistant enterococci (VRE), among patients is a growing concern. One critical aspect of bacterial transfer is the ability of the microorganism to
survive on various common hospital surfaces. The purpose of this study
was to determine the survival of 22 gram-positive bacteria (vancomycin-sensitive and -resistant enterococci and
methicillin-sensitive and -resistant staphylococci) on five common
hospital materials: smooth 100% cotton (clothing), 100% cotton terry
(towels), 60% cotton-40% polyester blend (scrub suits and lab
coats), 100% polyester (privacy drapes), and 100% polypropylene
plastic (splash aprons). Swatches were inoculated with 104
to 105 CFU of a microorganism, assayed daily by placing the
swatches in nutritive media, and examining for growth after 48 h.
All isolates survived for at least 1 day, and some survived for more
than 90 days on the various materials. Smaller inocula
(102) survived for shorter times but still generally for
days. Antibiotic sensitivity had no consistent effect on survival. The
long survival of these bacteria, including MRSA and VRE, on commonly
used hospital fabrics, such as scrub suits, lab coats, and hospital
privacy drapes, underscores the need for meticulous contact control
procedures and careful disinfection to limit the spread of these bacteria.
