Assays for monitoringToxoplasma gondiiinfectivity in the laboratory mouse

Abstract

AbstractToxoplasmais a widespread parasite of animals including many rodents that are a natural part of the transmission cycle between cats, which serve as the definitive host. Although wild rodents, including house mice, are relatively resistant, laboratory mice are highly susceptible to infection. As such, laboratory mice and have been used to compare pathogenesis of natural variants, and to evaluate the contributions of both host and parasite genes to infection. Protocols are provided here for evaluating acute and chronic infection with different parasite strains in laboratory mice. These protocols should provide uniform standards for evaluating natural variants and attenuated mutants and for comparing outcomes across different studies and between different laboratories.
