In this outbreak, 12 patients in intensive care units acquired a Chryseobacterium indologenes infection. Cultures from sinkholes and air samples were positive for C. indologenes. After removing wash basins, no new cases appeared. Sinkholes, potentially contaminated, can act as a reservoir for C. indologenes and other microorganisms. Thus, patients and equipment should be protected from sink splashes to avoid contamination.
