Postmortem bacteriology

Intrinsic Bacteria in Meat

“…The concept of 'agonal' invasion of the body by bacteria from the gut appears to have been introduced by pathologists to account for discrepancies between clinical and postmortem studies of the bacteriological state of human tissues. It is possible to offer alternative explanations for these observations and the field has been the subject of a critical review by Koneman (1970). He concludes that there is no clear evidence for agonal invasion, but in at least half of all cases it does not occur.…”

“…Other workers have reported that such an increase does occur (Carpenter & Wilkins 1964) but a critical review of this work indicates that their methods of analysis resulted in erroneous conclusions. There is no evidence that postmortem invasion from the gut occurs for at least 15 h after death (Koneman 1970). The absence of agonal and post-mortem invasion after sudden death is attested by the routine collection of cadaveric blood for transfusion in the U.S.S.R. (Tarasov 1960).…”

“…Koneman [27] argues that “bacterial invasion apparently does not occur, at least not for 15 hours after death and possibly even as long as 48 hours; therefore post‐mortem culture results obtained within that time span are valid”.…”

“…Im Gegensatz dam dient der Begriff ,,intrinsic bacteria" fur denjenigen Keimanteil, der in Tiefengewebe von Schlachttieren aufzufinden ist (26). Damit (37). Eine Invasion in Organe und Muskulatur zu einem friiheren Zeitpunkt erscheint eigentlich nur moglich, wenn eine Schadigung des betreffenden Organgewebes vorliegt (32, 15,16).…”
