The genus Borrelia is represented by spirochetes that, once entered the human or animal body, can migrate to different organs, including the central nervous system. The aim of the study was to develop a murine neuroborreliosis model by inoculating a strain of Borrelia burgdorferi (Bb). 2 studies were conducted using BALB/c and CD1 mice strains, female, 8 weeks old, 22 grams at baseline. The selected animals were inoculated with Bb (106 spirochetes/mL), depending on the protocol, intradermally (100μL/animal) or intracerebrally (10μL/animal). For the evaluation of the neuroborreliosis development, endpoints were established at 1, 3, 6, 8 and 13 weeks post-infection, when samples of dura mater, brain, ear, heart, knee joint and bladder were collected, and maintained in culture medium specific for the growth of Borrelia. Recovery of Bb was possible from samples harvested 7 days post-infection from animals inoculated both intradermally and intracerebrally. Through the experiments we have developed a model of neuroborreliosis in two mice strains that can be useful for the study of the development of new therapeutic approaches.
