Partnership Focuses on Developing East Coast Fever Vaccine

05.10.2011
A vaccine that protects cattle against East Coast fever, a destructive disease in eastern and central Africa, is being developed by scientists at the U.S. Department of Agriculture (USDA) and the International Livestock Research Institute (ILRI) in Kenya.

Entomologist Glen Scoles, veterinary medical officer Massaro Ueti and research leader Don Knowles at the Agricultural Research Service (ARS) Animal Disease Research Unit (ADRU) in Pullman, Wash., have been working on the collaborative project for more than five years. ARS is USDA's chief intramural scientific research agency. This research, which looks at combination vaccines for tick-borne diseases, supports USDA's priority of promoting international food security.

Scientists are focusing on the tick that transmits the parasite responsible for East Coast fever, according to Scoles. Because the tick and parasite are similar to the tick and parasite that cause Texas cattle fever in the United States, developing a vaccine for East Coast fever could lead to a vaccine for Texas cattle fever.

In an initial study, scientists developed a polymerase chain reaction (PCR) test that detects parasite DNA in ticks. They used tick populations that were produced at ILRI to have different susceptibilities. Two different strains of ticks- Muguga and Kiambu- were compared. The Muguga ticks had a low level of parasitic infection, whereas the Kiambu ticks were highly susceptible.

Understanding genetic differences between these two tick populations could lead to the identification of proteins that might be good targets for a vaccine to help control East Coast fever, according to Scoles.

The international partnership demonstrates a global community effort to control diseases that limit food and fiber production, according to Knowles. Although East Coast fever isn't currently a problem in the United States, this collaborative research aids in keeping it free of the disease and reducing future risk in other countries. Results of this collaborative research also may be applied to help control other similar parasitic diseases.

Findings from this research were published in Gene and in the Journal of Medical Entomology.

Read more about this research in the October 2011 issue of Agricultural Research magazine.

Im Focus: Sinking islands: Does the rise of sea level endanger the Takuu Atoll in the Pacific?

In the last decades, sea level has been rising continuously – about 3.3 mm per year. For reef islands such as the Maldives or the Marshall Islands a sinister picture is being painted evoking the demise of the island states and their cultures. Are the effects of sea-level rise already noticeable on reef islands? Scientists from the ZMT have now answered this question for the Takuu Atoll, a group of Pacific islands, located northeast of Papua New Guinea.

Im Focus: Energy-saving minicomputers for the ‘Internet of Things’

The ‘Internet of Things’ is growing rapidly. Mobile phones, washing machines and the milk bottle in the fridge: the idea is that minicomputers connected to these will be able to process information, receive and send data. This requires electrical power. Transistors that are capable of switching information with a single electron use far less power than field effect transistors that are commonly used in computers. However, these innovative electronic switches do not yet work at room temperature. Scientists working on the new EU research project ‘Ions4Set’ intend to change this. The program will be launched on February 1. It is coordinated by the Helmholtz-Zentrum Dresden-Rossendorf (HZDR).

“Billions of tiny computers will in future communicate with each other via the Internet or locally. Yet power consumption currently remains a great obstacle”,...
