Research Interests

Short Bowel Syndrome (SBS), a condition in which a person lacks sufficient bowel length to accommodate adequate nutrition and growth, presents a challenging clinical picture. Children and adults with SBS often have frequent, alternating periods of poor absorption, increased gas or bloating, pain, and diarrhea. These symptoms are often attributed to small bowel bacterial overgrowth (SBBO), and patients are treated with a variety of antibiotic or probiotic regimens.

>Diagnosis of SBBO using current standards including both indirect testing such as breath hydrogen testing and direct testing via small bowel aspirate cultures and biopsies is often inconclusive and as such SBBO remains largely a clinical diagnosis.

>New culture-independent molecular techniques, utilizing a highly conserved region of 16S rDNA have been widely used to characterize bacterial diversity. Dr. Davidovics’ research goal is to quantify and characterize the microbiota in SBS patients with SBBO with real-time PCR amplification and DNA sequencing, and to correlate disease specific meta-genomic signatures with host tissue and immune response.
