New patent propels UTSA biology researchers toward tularemia vaccine development


Share this Story

(July 2, 2010)--Karl Klose, director of the UTSA South Texas Center Emerging Infectious Diseases (STCEID), and Bernard Arulanandam, associate dean of research for scientific innovation in the UTSA College of Sciences, have been granted a U.S. patent for developing a process to create a vaccine for the deadly tularemia infection.

Tularemia, caused by the highly infectious bacterium Francisella tularensis, can cause serious disease in humans. F. tularensis is carried primarily by animals such as rabbits and rarely causes human infections, but when breathed in through the lungs, the disease can be fatal. Because of this, F. tularensis is considered a potential bioweapon.

"We developed what is called a 'live attenuated vaccine,' by removing Francisella's IglD gene, which is critical for the bacteria to be able to survive and grow inside infected cells," said Klose. "In a series of studies over three years, we characterized the IglD gene, knocked it out, and observed that the crippled bacterium was able to act as an effective vaccine by inducing an immune response without causing tularemia. This research is a promising advance in our attempts to develop a vaccine against this potential bioweapon."

F. tularensis is one of many organisms the researchers in the STCEID are investigating with an eye for vaccine development. Researchers are also working on vaccines for Valley Fever, Lyme disease and anthrax.

As UTSA continues to move toward Tier One research status, it has developed an increased focus on innovation, commercialization and technology transfer.

"Last year, UTSA signed its first commercial license to develop a chlamydia vaccine with pharmaceutical company Merck based on research from our South Texas Center for Emerging Infectious Diseases and the Department of Microbiology and Immunology at the University of Texas Health Science Center at San Antonio," said Arulanandam. "We are hopeful that the science behind this new patent for Francisella will spur further insight into the creation of an effective vaccine against this pathogen."


The South Texas Center for Emerging Infectious Diseases (STCEID) focuses on research in molecular microbiology, immunology, medical mycology, virology, microbial genomics, vaccine development and biodefense. The center also provides hands-on training to undergraduate and graduate students who intend to pursue careers in science and technology. Working with the UTSA College of Sciences Department of Biology, center faculty have established an undergraduate academic track in microbiology, a master's program in biology and biotechnology and a Ph.D. program in cell and molecular biology.

UTSA writes the book on all-digital libraries

As touch screens and e-books demand more and more attention from both casual readers and scholars, many people say the handwriting is on the wall for the printed page.

At UTSA, the handwriting is on the wall for a library that doesn't have any printed books.

Since March 2010, the bookless library in the Applied Engineering and Technology Building has given UTSA students an innovative way to read, research and work with each other to solve problems.

With ultra-modern furniture and a décor featuring desktop computers, scanners and LCD screens, the AET Library is designed to engage students in an online format. But it also offers group study niches and study rooms with whiteboards and glass walls on which students can write. The space encourages teamwork, communications and problem solving for the next generation of scientists and professional engineers.

Did you know? The UTSA AET Library is the nation's first completely bookless library on a college or university campus. It served as a model for Bexar County's first-in-the-nation public bookless library system and one of its branches, the Dr. Ricardo Romo BiblioTech.
