The Digestive Diseases and Microbiota group is interested in understanding the role of these microorganisms (bacteria among others) living in the intestine and how alterations to their proportions affect human health and disease. We are a multidisciplinary team with basic basic and clinic researchers. To respond to our research topics we are conducting clinical studies in humans and independent culture techniques focused on DNA sequencing using PCR techniques, and specifically, the 16S rRNA gene of microorganisms present in tissue samples, saliva and / or faeces from patients with different pathologies. These tools allow us to address a whole series of biological issues from a descriptive and functional perspective with the background of exploring the role of intestinal microbiota as an activating agent and as a diagnostic and prognostic tool in the field of different diseases: Crohn's disease and ulcerative colitis, colon cancer, irritable bowel syndrome, celiac disease, chronic pancreatitis, fatty liver, rheumatoid arthritis, colon, and pancreas cancer.

Main lines of research

Our main line of research is the study of microbiota in digestive diseases (inflammatory intestinal disease, colorectal cancer, chronic pancreatitis, pancreatic cancer, hepatic steatosis, hepatocarcinoma, etc.), with the intention of finding microbiological markers that can be used as prognosis, diagnosis and monitoring tools and support for these digestive pathologies.

Strategic objectives

Our group will focus its efforts around three very clear goals:

  1. Dysbiosis indicators

Work on a broad-ranging study in the correlation of indices developed during the previous period (MC and CRC) with clinical determinants of intestinal diseases for risk determination, pre-diagnosis screening and intestinal disease monitoring.

These tools for monitoring the state of the intestinal microbiota will allow delve deeper into the concept of mucous healing,  a condition that involves the reversion of a dysbiosis situation to basal or normal conditions.

  1. AIEC

Identify genetic elements involved in the pathotype "Adherent-invasive Escherichia coli' and molecular tool design for its detection in patients with Crohn's disease

  1. Hepatopancreatic line

Explore the establishment of a new line in the hepatopancreatic field dedicated to exploring the possible microbiological markers in faeces from patients with chronic pancreatitis that progress to pancreatic cancer and patients with hepatic steatosis who develop hepatocarcinoma. In fact this year (2015), Dr. Silvia Virolés has begun her thesis focusing on the study of the microbiota during the different phases of hepatic steatosis until the onset of hepatocarcinoma, with the aim of finding a microbiological marker linked to the prognosis for this disease.
