Printcultures for postmortem microbiology.

A modified printculture method for postmortem bacteriology was compared to the traditional tissue homogenate inoculum method. The two methods were comparable in their recovery rate of bacterial isolates. However, printcultures is an easy and rapid method; thus, it is superior to the traditional technique for postmortem culture. Histologic examination of most postmortem lung specimens with no bacterial growth showed no evidence of pneumonia or bronchitis, suggesting that the lack of growth is a reliable indicator of no bacterial infection.
