Researchers create better methods to detect E. 1xbet best casino website

Monday, June 16, 2014



MANHATTAN — Kansas State University diagnosticians are helping the cattle industry save millions of dollars each year by developing earlier and accurate detection of E. 1xbet best casino website .

Lance 1xbet best casino website , master's student in veterinary biomedical science, Greensburg; T.G. Nagaraja, university distinguished professor of diagnostic medicine and pathobiology; and Jianfa Bai, assistant professor in the Kansas State Veterinary Diagnostic Laboratory, are leading a project to improve techniques for detecting pathogenic Shiga toxin-producing E. 1xbet best casino website O157:H7. A U.S. Department of Agriculture Coordinated Agriculture Project grant is funding the work.

The researchers are part of a College of Veterinary Medicine team studying preharvest food safety in beef cattle. Noll has developed and validated a molecular assay that can detect and quantify major genes specific for E. 1xbet best casino website O157.

"Developing a method to detect E. 1xbet best casino website before it can potentially contaminate the food supply benefits the beef industry by preventing costly recalls but also benefits the consumer by ensuring the safety of the beef supply," Noll said.

The newly developed test is a molecular assay, or polymerase chain reaction, that detects bacteria based on genetic sequences, which are the bacteria's "fingerprints," Nagaraja said. The test is rapid and less labor-intensive than existing detection methods. The method can be automated and test many samples in a short period of time.

The test can be used in a diagnostic or research laboratory to accurately detect E. 1xbet best casino website and can help with quality control in cattle facilities.

"The novelty of this test is that it targets four genes," Nagaraja said. "We are constantly working on finding better and more sensitive ways to detect these pathogens of E. 1xbet best casino website in cattle feces."

To develop the diagnostic test, Noll and Nagaraja worked with two 1xbet best casino website molecular biologists: Xiaorong Shi, research assistant of diagnostic medicine and pathobiology, and Bai.

"Beef cattle production is a major industry in Kansas and 1xbet best casino website has a rich tradition in the research of beef cattle production and beef safety," Noll said. "As a graduate student in veterinary biomedical sciences, I am proud to be a member of a multidisciplinary team in the College of Veterinary Medicine that aims to make beef a safe product for the consumers."

Noll was named a winner at the 11th annual Capitol Graduate Research Summit this spring for his research project and poster, "A four-plex real-time PCR assay for the detection and quantification of Escherichia 1xbet best casino website O157 in cattle feces."
