1. Sympatry influence in the interaction of Trypanosoma cruzi with triatomine
Abstract INTRODUCTION: Trypanosoma cruzi, the etiologic agent of Chagas disease, is widely distributed in nature, circulating between triatomine bugs and sylvatic mammals, and has large genetic diversity. Both the vector species and the genetic lineages of T. cruzi present a varied geographical distribution. This study aimed to verify the influence of sympa

2. Grupos split metacíclicos e formas espaciais esféricas metacíclicas / Split metacyclic groups and split metacyclic spherical space forms
Neste trabalho, estudamos a ação dos grupos split metacíclicos \ D IND. (2h+1) POT. 2 nas esferas. Encontramos uma região fundamental dos espaços quocientes, chamados de Formas Espaciais Esféricas Metacíclicas, que foi utilizada para construirmos um conveniente complexo de cadeias destas formas com o qual calculamos o anel de cohomologia e a torção

3. Códigos metacíclicos / Metacyclic Codes
Neste trabalho, estudamos os códigos corretores de erros que são ideais na álgebra de grupo FG(M;N;R) sobre um corpo F de característica 2, onde o grupo subjacente é metacíclico, não abeliano, de ordem ímpar e possui a seguinte apresentação: G(M;N;R) = ‹a, b : aM = bN = 1, ba = aRb›; onde mdc(M;R) = 1, RN = 1(mod M) e R ≠ 1.

4. Estudo das proteínas da família gp82 das formas metacíclicas do Trypanosoma cruzi / Study of gp82 family proteins of Trypanosoma cruzi metacyclic forms
The main goal of this work was to characterize the proteins encoded by the gp82 gene fami ly, which is part of the large T. cruzi gp85/trans-sialidase multigenic family. Previous studies had focused on the surface gp82, which is engaged in the cell invasion by CL strain metacyclic forms and is identified by monoclonal antibody (MAb) 3F6. Firstly, we investig

5. Distribuição de macrófagos e alterações teciduais no coração e na medula espinhal de cães inoculados com formas tripomastigotas metacíclicas ou sangüíneas da cepa Berenice-78 do Trypanosoma cruzi submetidos à imunossupressão durante a fase aguda da infecção
Trypanosoma cruzi, the causative agent of Chagas disease, affects not only cardiac and intestinal structures but also neurological structures. Experimental canine model of T. cruzi infection has been shown to mimetize the various aspects of Chagas disease. Our group has been demonstrated that the source of the inoculum (blood-BT or metacyclic trypomastigotes

6. Action of Trypanosoma rangeli in infections with virulent Trypanosoma cruzi populations
In experimental murine infections with Trypanosoma rangeli it has been observed development immune response to Trypanosoma cruzi. The aim of the present work was to analyze the result of antigenic stimuli and the protective effect with T. rangeli in T. cruzi infections. Mice groups immunized with metacyclic trypomastigotes of T. rangeli (Choachí-2V strain),

7. Resistance of cattle to tsetse-transmitted challenge with Trypanosoma brucei or Trypanosoma congolense after spontaneous recovery from syringe-passaged infections.
Groups of cattle were inoculated intravenously with cloned populations of bloodstream forms of Trypanosoma brucei or Trypanosoma congolense. All five steers infected with T. brucei ILTat 2.1 and six of the eight steers infected with T. congolense IL 13-E14 became aparasitemic within 16 and 32 weeks postinfection, respectively. Examination of sera from animal

8. Apparent exhaustion of the variable antigen repertoires of Trypanosoma vivax in infected cattle.
Three groups of cattle, each group comprising six animals, were inoculated intravenously with populations of bloodstream forms of Trypanosoma vivax. The first group received T. vivax clone ILDat 1.3 derived from an isolate from Nigeria, while the other two received T. vivax stocks IL 1875 or IL 2133 isolated from Coast Province, Kenya. One animal from the gr

9. Dendritic Cell Populations in Leishmania major-Infected Skin and Draining Lymph Nodes
Using a metacyclic promastigote ear infection model of cutaneous leishmaniasis, we examined the phenotype, parasite load, and cytokine production of dendritic cells in the skin and draining lymph nodes of resistant C57BL/6J and susceptible BALB/c mice. Five dendritic cell populations were isolated from the skin and lymph nodes, and the main difference betwee

10. Prevalence of antibodies to 72-kilodalton glycoprotein (GP72) in patients with Chagas' disease and further evidence of zymodeme-associated expression of GP72 carbohydrate epitopes.
Three competitive inhibition enzyme-linked immunosorbent assays were developed to examine the expression of the 72-kilodalton glycoprotein (GP72) and of a GP72 carbohydrate epitope in Trypanosoma cruzi strains and clones. A total of 148 strains and clones of known isozyme phenotype (principal zymodeme, Z) were tested. With monoclonal antibody 8G2B9 the enzym
