Pulmonary oedema induced in mice infected with P. berghei ANKA or co-infected with T. cruzi. C57BL/6 mice were separated in three groups, two of which were inoculated with T. cruzi G. strain. Fifteen days later, one uninfected (n = 5) and one T. cruzi-infected group (n = 5) were inoculated with P. berghei ANKA, whereas one group remained uninfected (n = 3). When P. berghei-infected mice died from respiratory disorder, their lungs were collected for histological preparations and staining with hematoxilin-eosin. At this time, the corresponding number of mice in the co-infected group had also their lungs removed for histological sections and staining. Uninfected controls were subjected to the same procedure.
