Research Focus

Hospital acquired infections are a major challenge to patient safety and public health. According to the U.S. Centers for Disease Control and Prevention (CDC), approximately 36 million people are admitted to U.S. hospitals every year, and nearly two million patients annually acquire an infection while being treated; over 80,000 patients die from complications resulting from the infection.

Clostridium 1xbet best casino website (C. 1xbet best casino website ) is one of the leading pathogens causing hospital-acquired infection in the United States. People in good health don't usually get sick from C. 1xbet best casino website . Our intestine contains millions of bacteria, which forms a barrier that protects us from this pathogenic bacterial infection. But when we take antibiotics, the drug can destroy some of the helpful bacteria in the gut and without enough healthy bacteria, C. 1xbet best casino website can quickly grow out of control and produce toxins that damage the intestinal cells. This results in diarrheal symptoms and sometime life threatening conditions called pseudomembranous colitis.

The C. 1xbet best casino website toxins, A and B encoding genes (tcdA and tcdB) are part of a pathogenicity locus (PaLoc) which also carry three other genes tcdR, tcdC and tcdE. The research in our lab focuses onC. 1xbet best casino website pathogenesis with a special interest on PaLoc genes and their role in virulence.

Mobile genetic elements such as transposons and temperate phages occupy nearly 11% of C. 1xbet best casino website genome. We are also interested in understanding the role of temperate phage in C. difficiletoxin gene regulation.
