About The Event
Researchers at Tulane University have found that a combination of antibiotics is more effective in treating Lyme disease than the commonly prescribed course of one single antibiotic. This finding, published in Frontiers in Microbiology, could pave the way for improved Lyme disease treatments, particularly in persistent cases that have not responded to standard antibiotic treatment.
While none of the single antibiotics completely eradicated the persistent infection after a 28-day treatment course, several combination therapies of already FDA-approved drugs, were successful in clearing the infection. Specifically, four different dual combinations of antibiotics (doxycycline and ceftriaxone; dapsone and rifampicin; dapsone and clofazimine; doxycycline and cefotaxime) and three triple combinations of antibiotics and antimicrobials (doxycycline, ceftriaxone and carbomycin; doxycycline, cefotaxime and loratadine; dapsone, rifampicin and clofazimine) eradicated persistent infections of the bacteria. These results suggest a need for further studies of combination antibiotic therapies in successfully eradicating Lyme disease.
Dr. Monica Embers, the lead researcher on the study, will discuss why Lyme persists and how her recent research may help to address it.
About The Speakers
Dr. Monica Embers is currently an Associate Professor in the Division of Immunology and the Director of Vector-borne Disease Research at the Tulane National Primate Research Center. Her research program regarding Lyme disease and its infectious cause Borrelia burgdorferi specializes in animal models. The research is centered around three major efforts: (1) identifying treatments that can eradicate B. burgdorferi infection; (2) detection of persistent Lyme disease spirochetes in human (autopsy) tissues; and (3) immunodiagnosis for B. burgdorferi infection and cure. By transmitting Lyme disease to mice and nonhuman primates by tick, and studying the natural course of infection, her group aims to attain a better understanding of the clinical quandaries of human Lyme disease, including effective diagnosis and treatment. Due to the many similarities between Bartonellosis and Lyme disease, her team has begun to develop research models for Bartonella infection. The goals of Bartonella research involve developing improved treatment strategies, understanding the pathophysiology of co-infection, and interrogating tick vector transmission of these pathogens.
