“…None were observed in this study, similarly to Ayala et al (1973) and Renjifo et al (1952). On the other hand, Thoisy et al (2000) found trypanosomatids in 19 (44%) and filarids in 17 (40%) of a total 43 free-ranging T. tetradactyla. Dereure et al (2001) also isolated Trypanosoma legeri from the blood of a free-ranging Tamandua tetradactyla.…”

(Sorocaba, SP, Brazil), and were considered healthy on physical examination. Examined parameters included red blood cell count, white blood cell count, hematocrit, hemoglobin concentration, mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, total plasmatic protein and differential leukocyte counts. Also, a survey for hemoparasites was done and none was observed in thin blood smears. The results were generally similar to those previously reported in the exiguous literature for these species, providing further reference data for the interpretation of laboratory results besides health monitoring, assisting early disease diagnosis and providing relevant information for conservation programs for these species.

“…Perfis fisiológicos de primatas neotropicais raramente são estabelecidos, pois esses animais são difíceis de capturar, e as condições de campo, muitas vezes, são desfavoráveis (Vie et al, 1998). Estes animais podem ser reservatórios silvestres de importantes doenças como febre amarela (Hull et al, 1991), malária (Thoisy et al, 2000) e amebiose (Thoisy et al, 2001), dentre outras.…”

“…The infection is insect vector transmitted to lizards, or they become infected upon the ingestion of a triatomine contaminated with T. cruzi (337). Cold-blooded animals retain cryptic infections (106,319). Mice inoculated with blood from an infected lizard can become infected with T. cruzi (429).…”

Pathogenesis of Chagas' Disease: Parasite Persistence and Autoimmunity

SUMMARY Acute Trypanosoma cruzi infections can be asymptomatic, but chronically infected individuals can die of Chagas' disease. The transfer of the parasite mitochondrial kinetoplast DNA (kDNA) minicircle to the genome of chagasic patients can explain the pathogenesis of the disease; in cases of Chagas' disease with evident cardiomyopathy, the kDNA minicircles integrate mainly into retrotransposons at several chromosomes, but the minicircles are also detected in coding regions of genes that regulate cell growth, differentiation, and immune responses. An accurate evaluation of the role played by the genotype alterations in the autoimmune rejection of self-tissues in Chagas' disease is achieved with the cross-kingdom chicken model system, which is refractory to T. cruzi infections. The inoculation of T. cruzi into embryonated eggs prior to incubation generates parasite-free chicks, which retain the kDNA minicircle sequence mainly in the macrochromosome coding genes. Crossbreeding transfers the kDNA mutations to the chicken progeny. The kDNA-mutated chickens develop severe cardiomyopathy in adult life and die of heart failure. The phenotyping of the lesions revealed that cytotoxic CD45, CD8 + γδ, and CD8α + T lymphocytes carry out the rejection of the chicken heart. These results suggest that the inflammatory cardiomyopathy of Chagas' disease is a genetically driven autoimmune disease.
