TCN2 and parasitic infectious disease: However, parasitemias at delivery of TcII and TcVI IAM dams having delivered congenitally infected pups were similar to those of corresponding infected mice having delivered uninfected pups (TcII: 7.5±3.9×105 vs 5.9±0.2×105 parasites/mL; TcVI: 1.6×106 vs 1.9±0.4×106 parasites/mL, respectively).
