A study of the predisposition of Schistosomiasis mansoni to pyogenic liver abscess in experimentally infected mice.

In murine experimental model, the present work was carried out to study the possible predisposition of S. mansoni infection to pyogenic liver abscess, through a concurrent infection with Staphylococcus aureus. Pyogenic liver abscesses containing the bacterial organism were found in 85% of mice infected with concurrent early S. mansoni infection and S. aureus, in 35% of mice with late S. mansoni infection and the bacterial infection, and in 60% of mice with concurrent immunosuppressed late St. mansoni infection and staphylococcal infection. The early S. mansoni infection, immunosuppressed late schistosomiasis mansoni, and to a less extant late schistosomiasis mansoni, with concurrent bacterial infections can predispose to pyogenic liver abscess which has implicative effect on clinical cases.
