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.

Optical quantum computers can revolutionize computer technology. A team of researchers led by scientists from Münster University and KIT now succeeded in putting a quantum optical experimental set-up onto a chip. In doing so, they have met one of the requirements for making it possible to use photonic circuits for optical quantum computers.
Optical quantum computers are what people are pinning their hopes on for tomorrow’s computer technology – whether for tap-proof data encryption, ultrafast...
The Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP has been developing various applications for OLED microdisplays based on organic semiconductors. By integrating the capabilities of an image sensor directly into the microdisplay, eye movements can be recorded by the smart glasses and utilized for guidance and control functions, as one example. The new design will be debuted at Augmented World Expo Europe (AWE) in Berlin at Booth B25, October 18th – 19th.
“Augmented-reality” and “wearables” have become terms we encounter almost daily. Both can make daily life a little simpler and provide valuable assistance for...
With the help of artificial intelligence, chemists from the University of Basel in Switzerland have computed the characteristics of about two million crystals made up of four chemical elements. The researchers were able to identify 90 previously unknown thermodynamically stable crystals that can be regarded as new materials. They report on their findings in the scientific journal Physical Review Letters.
Elpasolite is a glassy, transparent, shiny and soft mineral with a cubic crystal structure. First discovered in El Paso County (Colorado, USA), it can also be...
For the first time, Fraunhofer IKTS shows additively manufactured hardmetal tools at WorldPM 2016 in Hamburg. Mechanical, chemical as well as a high heat resistance and extreme hardness are required from tools that are used in mechanical and automotive engineering or in plastics and building materials industry. Researchers at the Fraunhofer Institute for Ceramic Technologies and Systems IKTS in Dresden managed the production of complex hardmetal tools via 3D printing in a quality that are in no way inferior to conventionally produced high-performance tools.
Fraunhofer IKTS counts decades of proven expertise in the development of hardmetals. To date, reliable cutting, drilling, pressing and stamping tools made of...
