Exploring genetics to combat malaria and Zika

The Zika virus has quickly become a major health threat, and researchers at Virginia Tech are looking for ways to curtail its spread.

The virus, which is primarily spread to humans by the bite of an infected mosquito, has been passed on to a growing number of Americans since early 2016, and the World Health Organization has declared it a Public Health Emergency of International Concern.

Biochemist Zhijian “Jake”  Tu is one of several Virginia Tech researchers zeroing in on the Zika virus. Tu is studying genes that turn biting female mosquitoes into males, and he is exploring genetic strategies to stop the transmission of the Zika virus by reducing the number of female mosquitoes. Male mosquitoes do not bite and are harmless to humans, while female mosquitoes bite humans to get the blood they need for egg production.

Extension is ahead of the curve on new food safety rules

Adrianna Vargo, director of grower services at Charlottesville’s Local Food Hub, has collaborated with Virginia Cooperative Extension to get critical information to growers regarding the Food and Drug Administration’s new Food Safety Modernization Act. Its aim is to make the food supply safer by shifting the focus from responding to food contamination problems to preventing them from occurring. The policy is the most sweeping reform of U.S. food safety laws for both human and animal foods in 70 years.

As part of its grower services program, the Local Food Hub’s Adrianna Vargo conducts a mock audit of Singing Earth Farm in Augusta County.

Vargo and Extension have acted as boots-on-the-ground liaisons for more than 60 growers throughout Virginia and in North Carolina by providing critical workshops to ensure producers will be able to comply with FSMA legislation.

“One of the aspects of this legislation that has been a huge concern for growers is water testing. FSMA requires so many more water tests throughout the growing season,” Vargo said. “Extension has been an invaluable resource for training. They have been very inclusive and responsive to growers’ needs.”

Private donor helps Virginia Family Nutrition Program give cookware to families in need

Family Nutrition Program participants learn healthy living strategies including healthy cooking, physical activity, and thrifty food shopping.

Virginia Cooperative Extension’s Family Nutrition Program recently launched a new pilot program called Let’s Get Cookin’. The program, taught by Family Nutrition Program Assistants in northern Virginia, focuses on healthy living strategies including healthy cooking, physical activity, and thrifty food shopping. At the end of each program series, participants who complete the entire course will receive a cookware set.

This initiative began in August 2016, when the Family Nutrition Program received a call from a private donor who wanted to contribute to the program. Since the Family Nutrition Program works with limited-resource families and SNAP recipients, the donor suggested giving cookware sets as an incentive to participants who completed the programs.

Freshwater shrimp become a big deal

As the freshwater shrimp in his ponds continued to grow and multiply, Charles Carter knew he had a good product to sell.

In his second year of production, Carter wanted to create product buzz in order to sell a portion of his production to local consumers. Carter was already selling his product wholesale as a member of the Virginia Aqua-Farmers Network Cooperative, but he also wanted to market retail.

And he knew just where to look for assistance — Virginia Cooperative Extension.

Enter Dan Kauffman, Extension seafood marketing specialist at the Virginia Seafood Agricultural Research and Extension Center in Hampton.

Kauffman had been helping freshwater shrimp producers get their products to market, which also involved another part of his résumé — his fondness for shrimp boils.

Tracking and stopping human and agricultural viruses

Viruses are molecular thieves that take from their hosts under the cloak of darkness. But now a Virginia Tech scientist has found a way to not only track viral hijackers, but also to potentially stop them from replicating.

The discovery has broad-ranging applications in stopping viral outbreaks such as hepatitis C in humans and a number of viruses in plants and animals because it applies to many viruses in the largest category of viral classes — positive-strand RNA viruses.

“Even though these viruses infect very different hosts, they all replicate similarly across the board, so what we learn from one virus can potentially be translated to control viruses in agricultural production as well as human health,” said Xiaofeng Wang, an assistant professor of plant pathology, physiology, and weed science in the College of Agriculture and Life Sciences.

Wang’s findings could target any number of plant viruses by developing sprays to halt the virus, which would save the agricultural sectors millions of dollars.

Wang used the brome mosaic virus to study how viral infections start. He found that by inhibiting host lipid cell synthesis, the viral replication stopped.
