Trypanosoma cruzi infection: do distinct populations cause intestinal motility alteration?
Parasitology Research 2010 June
Chagas disease, caused by Trypanosoma cruzi, is an important public health problem in Latin America. Disturbances in gastrointestinal motility are observed in 15-20% of patients at the chronic phase. We previously observed a decrease in intestinal motility in mice infected with Y strain from T. cruzi. Thus, we decided to test if infection with other T. cruzi strains also caused the intestinal disturbance. Male adult Swiss mice were infected intraperitoneally with CL-Brener clone (CL-B), Brazil strain (Br), or Dm28 clone (Dm) of T. cruzi. All infected mice presented a low cumulative mortality (CL-B, 17%; Br, 8%; Dm, 25%) at 35 days post infection (dpi) and their typical parasitemia curves. Br and Dm groups exhibited a maximal reduction of intestinal motility at 35 dpi (176.8 +/- 51.3 and 198.3 +/- 52.6 min, respectively), when compared with non-infected mice (90.2 +/- 19.5 min). However, CL mice presented the peak of delayed intestinal transit at 12 dpi (191.0 +/- 33.3 min), when compared with non-infected mice (105.6 +/- 26.4 min), very close to the 15 dpi for the intense alteration (310.2 +/- 67.4 min) observed with the Y strain. We clearly demonstrate a reduction in intestinal motility in mice infected with different groups of T. cruzi during the acute phase of the infection. Since Br, Dm, and CL strains presented low mortality rates in adult Swiss mice, a prospective study concerning the chronic intestinal alteration is encouraged, particularly for studies of alternative therapies.
