Estimation of the post-mortem interval in beagle dogs.

Estimation of the time that has elapsed between death and the post-mortem examination of a body contributes to the investigation of death by defining the period during which death may have occurred. In a veterinary context, investigations involve a range of incidents including out-of-season shooting of game animals, poaching, death during transportation and cases of neglect or non-accidental injury of domestic animals. This study on dogs of the same breed, of similar weights and held under identical conditions, shows that a combination of rectal temperature, environmental temperature, gross pathology and histological changes can provide a scientifically based estimate of the post-mortem interval during the first 10 h following death, of up to one day, one to three days, three to seven days and one to three weeks.

The health of wild red and sika deer in Scotland: an analysis of key endoparasites and recommendations for monitoring disease.

Monitoring the health of wildlife populations is important for understanding and controlling the risk of infections to livestock, humans and/or other wildlife. In this paper, we analyse the results of surveys of parasites and non-specific signs of diseases carried out on organs from 638 red and 107 sika deer culled in four regions of Scotland between 1991 and 1997. Infections of the lung by Elaphostrongylus spp. were significantly greater in red than sika deer. Older animals were more heavily infected with Elaphostrongylus spp. and Sarcocystis spp., and infections with Sarcocystis spp. tended to be heavier in more recent years. The results suggest that a combination of key indicator parasite species and non-specific signs of disease may be useful for monitoring the health of wildlife populations at a national scale. However, they also demonstrate that such monitoring needs to be long-term, carried out according to standard protocols and at an appropriate resolution to enable integration with data on other potentially influential environmental factors.
