In fatal cases of meningococcal septicemia, bacteriological diagnosis may not be straightforward due to postmortem replication and relocation of endogenic microflora. In medicolegal practice, aside from routine autopsy and histopathology, also other diagnostic methods, such as microbiological tests, immunohistochemistry and polymerase chain reaction (PCR), are used to examine body fluids and tissues.
We present the case of sudden death in a 2-year-old child. The patient died approximately 30 min after hospital admission before any routine diagnostic procedures were undertaken. Presence of whole-body rash and fulminant course of the disease raised suspicion of meningococcal septicemia. An autopsy was performed seven days after death when the body showed the signs of late postmortem decomposition. No etiological factor of septicemia could be identified based on macro- and microscopic findings. However, PCR demonstrated the presence of genetic material of group W in patient's cerebrospinal fluid and blood.
Microbiological PCR should be conducted postmortem whenever a specific etiological factor could not be identified with conventional methods.
