Texas A&M biologist fights deadly gut bacteria, C. diff
Date:8/29/2013

A Texas A&M University biologist has received a federal grant to study the fecal samples of hundreds of people to better understand the gut bacteria Clostridium difficile the cause of some 14,000 deaths a year in America and to help lay the basic science foundation to develop drugs to combat its deadly results.

Joseph Sorg, an assistant professor in the Department of Biology since 2010, is among a wave of younger researchers studying C. difficile as it has gained more attention in the U.S. in recent years. These bacteria cause infections primarily during hospital visits, when antibiotics alter the composition of microbial flora in the colon and make patients, most commonly the elderly, vulnerable to infection.

Death can occur in the most severe cases, but more likely, C. difficile infection results in severe diarrhea which unleashes into the environment dormant spores that are immune to antibiotic treatment.

Although antibiotics successfully treat the active C. difficile infection, patients are left susceptible to recurring infections. Beyond the psychological and physical toll it takes on its victims, C. difficile is an economic burden: A 2011 University of Pittsburgh study estimated that costs related to infections exceed $1.8 billion.

"If you talk to people who have C. diff and are relapsing, they are miserable," Sorg said. "We want to make sure that we can eventually treat people and prevent them from relapsing, or even keep them from becoming infected in the first place. C. diff is one of the most common hospital-acquired infections now, so it's a big problem in the U.S. and other industrialized nations."

Sorg and his postdoctoral mentor at Tufts University, Abraham Sonenshein, have started a company to commercialize their research, Spordiff Therapeutics, in an effort to create a drug that would prevent the dormant spores from growing and causing disease, a
