QUEIROZ, Maisa Leite de et al. Behavioral changes in Rattus norvegicus coinfected by Toxocara canis and Toxoplasma gondii. Rev. Inst. Med. trop. S. Paulo [online]. 2013, vol.55, n.1, pp.51-53. ISSN 1678-9946.

Using an elevated plus maze apparatus and an activity cage, behavioral changes in Rattus norvegicus concomitantly infected by Toxocara canis and Toxoplasma gondii were studied, during a period of 120 days. Rats infected by Toxocara canis or Toxoplasma gondii showed significant behavioral changes; however, in the group coinfected by both parasites a behavioral pattern similar to that found in the group not infected was observed thirty days after infection, suggesting the occurrence of modulation in the behavioral response.

Keywords : Behavioral changes; Toxocara canis; Toxoplasma gondii; Concomitant infections.
