Dr. Wooten's laboratory is interested in the host/pathogen interactions that lead to the development of two different infectious diseases: Lyme disease and melioidosis.


Lyme disease (i.e. Lyme borreliosis) is a particularly interesting and complicated malady that involves two major events: 1) persistent infection of the host by the spirochetal bacterium Borrelia burgdorferi and 2) the response of the host's innate immune defenses to the organism, which produces the inflammation that leads to the symptoms of Lyme disease. B. burgdorferi is a highly infectious tick-borne obligate parasite that is especially adept at evading host defenses, disseminating widely via spirochetal motility through dense tissues, and persisting long-term within almost any tissue of the body. The infected host mounts a vigorous immune response to these spirochetes, as evidenced by the production of inflammatory soluble mediators and large quantities of B. burgdorferi-specific antibodies. Although passive transfer of B. burgdorferi-specific antiserum can prevent naive mice from subsequent infection, the immune response elicited during natural infection is usually unable to clear the infection, resulting in a persisting bacterial reservoir that can re-emerge under various conditions. This persistence in target tissues promotes prolonged stimulation of the host's innate defenses via interaction with endogenous bacterial lipoproteins, resulting in activation of immune pathways that appear to mediate much of the inflammatory pathology indicative of Lyme disease. Based on these dynamics, we are interested in utilizing the well-established murine model of Lyme disease to address the following areas:

    • Identification of host immune cell types and mediators that are important in controlling the abilities of B. burgdorferi to infect, invade, and persist in mammalian host tissues.
    • Identification of host signaling pathways that modulate the inflammatory pathology that is characteristic for Lyme disease.
    • Development of intravital microscopy techniques that allow direct visualization of the interactions between B. burgdorferi and different immune cell populations within the intact skin of infected mice.
    • Assessment of the importance of B. burgdorferi motility and chemotaxis mechanisms for establishing acute and persistent infection in vertebrate and invertebrate hosts.

Melioidosis is a human and animal disease that is caused by infection with Burkholderia pseudomallei, which is endemic within different tropical and subtropical regions worldwide. Acute disease can lead to fulminant septicemia with mortality rates of 40-90%, even with vigorous antibiotic and supportive therapy. Chronic disease can also develop, with recrudescence occurring months to years after initial exposure. While there are some predisposing factors that make certain human populations more susceptible to developing this disease (e.g. diabetes, alcohol abuse, renal disease, etc.), exposure to B. pseudomallei-containing aerosols is reported to have an LD50 ≤100 organisms in mice, thus giving it considerable potential for misuse as a biological weapon. This organism is also quite resistant to many classes of antibiotics and there is currently no vaccine. Thus there is great interest in identifying targets for preventative and/or curative treatments for these infections.

Persistence within macrophages and other cell types appears to be central to the development of melioidosis, providing them an environment where they can proliferate and spread cell-to-cell via actin polymerization, thus enabling the bacteria to spread and evade humoral immune mediators. Relatively little is known about the molecular basis for B. pseudomallei virulence, but it appears that these bacteria quickly escape the phagosome and evade intracellular killing, preventing bacterial clearance and generation of an effective adaptive immune response. A better understanding of the basic biology of macrophage/phagocyte subversion by this bacterium would greatly facilitate the development of preventative and curative treatments. We are interested in utilizing the recently-developed murine model of melioidosis to address the following areas:

  • Identification of mechanisms that virulent B. pseudomallei strains utilize to circumvent efficient clearance by macrophages/neutrophils.
  • Identification of outer membrane proteins expressed by B. pseudomallei that might serve as virulence factors/vaccine candidates.
  • Testing vaccines in animal models to assess effectiveness and identify immune correlates of clearance.

Dr. Wooten received his Bachelors (Zoology/Chemistry; 1985) and Masters (Microbiology/Immunology; 1990) from the University of Arkansas (Fayetteville) under the supervision of Dr. Jim Saunders. He received his Ph.D. (Microbiology/Immunology; 1995) from the University of Mississippi Medical Center under the supervision of Dr. Jan Bly. He completed post-doctoral training at the University of Utah College of Medicine in the laboratory of Dr. Janis Weis. Dr. Wooten joined the Department of Medical Microbiology and Immunology at the University of Toledo College of Medicine in May 2001.
