Dr. Shazia Beg, a UCF Health rheumatologist at our Lake Nona office, has published a study along with Dr. Saleh Naser from the UCF College of Medicine that shows a link between rheumatoid arthritis and a common bacteria found in about half the cows in the United States. Mycobacterium avium subspecies paratuberculosis, known as MAP, may be a trigger for developing rheumatoid arthritis in people who are genetically at risk. The study is published in the Frontiers in Cellular and Infection Microbiology journal.
