Rates of trypomastigote adherence, interiorization, amastigote division in, and trypomastigote release from Vero cells were measured for Trypanosoma cruzi isolates from a dog (Tc-D), opossum (Tc-O), and an armadillo (Tc-A) from Louisiana. Because the Tc-O and Tc-A (wild isolates) trypomastigotes became interiorized rapidly, the media were quickly depleted of trypomastigotes thus reducing the numbers available to adhere to cells. In contrast, the Tc-D trypomastigote interiorization rate was slower. Intracellular amastigote division rate was slower for the Tc-D than the wild isolates. The Tc-D trypomastigotes were released from cells approximately 2 days later than wild isolate trypomastigotes, but twice the number were released. Growth rate for Tc-D epimastigotes in liver infusion tryptose media was faster than that of wild isolates. The doubling times for Tc-D, Tc-O, and Tc-A were 48.0, 69.0, and 67.4 hr, respectively. Soluble parasite extract was produced from epimastigotes of each isolate by freeze/thawing, sonication, and high-speed centrifugation. Proteins were separated on an SDS-PAGE slab gel and stained with Coomassie blue. Although similar bands were present in each preparation, the general pattern of staining was similar only between the Tc-O and Tc-A preparations, which showed some differences from the Tc-D preparation. Each isolate was zymodeme typed using 5 enzymes in lysates produced from epimastigotes of each isolate. Enzymes were separated electrophoretically and stained. Wild isolates showed similar patterns as zymodeme 1 reference stock, whereas the Tc-D isolate produced a pattern that did not resemble any of the reference stocks examined.
