Crime Scene Investigates: The Case of the Dead Cow

06.04.2006
Forensic fingerprinting of plant DNA is being investigated as a way to identify offending poisonous plants – a major cause of death in livestock in countries such as Ghana.

Dr Domozoro will describe how he uses plant DNA from the animal’s stomach for forensic fingerprinting on Thursday 6th April at the Society for Experimental Biology’s Annual Main Meeting, Canterbury [session P6]. “Knowing the offending plants will help us to manage the poisoning outbreak by targeting specific treatment routines or withdrawing livestock from infested pastures”, says Domozoro.

Since the identifying features of plants are rapidly digested in the stomach of herbivores it is often difficult to tell if and how an animal has been poisoned. Such misdiagnoses are costly to the agricultural industry and also mean that statistics on how widespread is poisoning are inaccurate. The practical application of this technique means that when a cow or sheep dies, if a sample of the rumen contents is taken within a day, it can be stored or used immediately to determine if plant poisoning was the cause of death.

Domozoro uses plant material, extracted from Ghanaian animals within 24 hours of death, as the template to amplify specific DNA sequences to give a plant-fingerprint: this is specific to the species of plant present in the animal’s rumen. Domozoro has affiliations with the Council for Scientific and Industrial Research in Ghana and so the first database he has used to search for a match consists of the known DNA sequences of ~40 poisonous Ghanaian plant species. This only represents a fraction of the known poisonous plants in Ghana and there is a need to keep expanding the database. The technique could be used to identify poisonous plants from any country as long as their DNA sequence is known: “The procedure can be applied anywhere, but the reference database will need to be carefully selected to include the geographical range”, explains Domozoro.

Im Focus: Hybrid optics bring color imaging using ultrathin metalenses into focus

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.

But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...

Im Focus: Stem cell divisions in the adult brain seen for the first time

Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.

The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...

Im Focus: Autonomous 3D scanner supports individual manufacturing processes

Let’s say the armrest is broken in your vintage car. As things stand, you would need a lot of luck and persistence to find the right spare part. But in the world of Industrie 4.0 and production with batch sizes of one, you can simply scan the armrest and print it out. This is made possible by the first ever 3D scanner capable of working autonomously and in real time. The autonomous scanning system will be on display at the Hannover Messe Preview on February 6 and at the Hannover Messe proper from April 23 to 27, 2018 (Hall 6, Booth A30).

Part of the charm of vintage cars is that they stopped making them long ago, so it is special when you do see one out on the roads. If something breaks or...
