Abstract
Toxoplasma gondii can infect almost all warm-blooded vertebrates with pathogensis
being largely influenced by the host immune status. As important epidemiological
hosts, rodents are globally distributed and are also commonly found infected with
haemoflagellates, such as those in the genus Trypanosoma. We here address whether
and how co-infection with trypanosomes can influence T. gondii infection in
laboratory models. Rats of five strains, co-infected with T. lewisi, and mice of four
strains, co-infected with T. musculi, were found to be more or less susceptible to T.
gondii infection, respectively, with corresponding increased or decreased brain cyst
burdens. Down-regulation of iNOS expression and decreased NO production or
reverse were observed in the peritoneal macrophages of rats or mice, infected with
trypanosomes, respectively. Trypanosoma lewisi and T. musculi can modulate host
immune responses, either by enhancement or suppression, and influence the outcome
of Toxoplasma infection.
