Nurses have an increased prevalence of H pylori antibodies that is significantly higher than the comparable prevalence of volunteer blood donors and is evident in the youngest age group. In addition, the increased prevalence is related to a longer duration of patient exposure in the nursing group.

Soon after our hospital instituted the BACTEC mycobacterial isolation system, the proportion of cultures positive for nontuberculous mycobacteria increased dramatically. After eliminating other possible sources of contamination, the BACTEC probe's sterilization time and temperature were increased, and the incidence of positive mycobacterial cultures returned to its former rate.
