Acidification modulates the traffic of Trypanosoma cruzi trypomastigotes in Vero cells harbouring Coxiella burnetii vacuoles
(Elsevier B.V., 2003-02-01)We studied the fate of different Trypanosoma cruzi trypomastigote forms after they invade Vero cells persistently colonised with Coxiella burnetii. When the invasion step was examined we found that persistent C. burnetii ...

Actin-rich structures formed during the invasion of cultured cells by infective forms of Trypanosoma cruzi
(Urban & Fischer Verlag, 1999-12-01)Previous work has shown that Trypanosoma cruzi extracellular amastigotes as well as metacyclic trypomastigotes infect cultured cells in a highly specific parasite form-cell type interaction. In this work we have investigated ...

Diagnosis of epithelial ingrowth after penetrating keratoplasty with confocal microscopy
(Lippincott Williams & Wilkins, 2006-10-01)Purpose: To report confocal microscopy use in the clinical diagnosis of epithelial ingrowth after penetrating keratoplasty (PKP).Methods: A 36-year-old female patient with keratoconus developed a well-delimited posterior ...

Disruption of myofibrillar proteins in cardiac muscle of Calomys callosus chronically infected with Trypanosoma cruzi and treated with immunosuppressive agent
(Springer, 2005-10-01)Calomys callosus (Rodentia: Cricetidae) chronically infected with CL strain of Trypanosoma cruzi undergo recrudescence of the acute phase when treated with the immunosuppressor cyclophosphamide. the distribution of ...

Distribution of epitopes of Trypanosoma cruzi amastigotes during the intracellular life cycle within mammalian cells
(Soc Protozoologists, 1997-07-01)In this study we have examined the distribution of epitopes defined by monoclonal antibodies raised against Trypanosoma cruzi amastigotes during the intracellular life cycle of the parasite. We have raised monoclonal ...

Diterpenoids from Azorella compacta (Umbelliferae) active on Trypanosoma cruzi
(Instituto Oswaldo Cruz, Ministério da Saúde, 2003-04-01)The anti-Trypanosoma cruzi activity of natural products isolated from Azorella compacta was evaluated, with particular emphasis on their effect against intracellular amastigotes. Five diterpenoids from A. compacta derived ...

Heterologous expression of a Trypanosoma cruzi surface glycoprotein (gp82) in mammalian cells indicates the existence of different signal sequence requirements and processing
(Soc Protozoologists, 1999-11-01)Metacyclic trypomastigotes of Trypanosoma cruzi express a developmentally regulated 82 kDa surface glycoprotein (gp82) that has been implicated in the mammalian cell invasion. When the non-infective epimastigote stage of ...

Motility, morphology and phylogeny of the plasmodial worm, Ceratomyxa vermiformis n. sp (Cnidaria: Myxozoa: Myxosporea)
(Cambridge Univ Press, 2017)The Myxozoa demonstrate extensive morphological simplification and miniaturization relative to their free-living cnidarian ancestors. This is particularly pronounced in the highly derived myxosporeans, which develop as ...

Phosphatidylinositol-specific phospholipase C (PI-PLC) cleavage of GPI-anchored surface molecules of Trypanosoma cruzi triggers in vitro morphological reorganization of trypomastigotes
(Soc Protozoologists, 2001-01-01)Trypanosoma cruzi trypomastigotes treated with phosphatidylinositol-specific phospholipase C (PI-PLC) in vitro are rapidly induced to differentiate into round forms. Using confocal microscopy, we were able to show that ...

Praziquantel and albendazole damaging action on in vitro developing Mesocestoides corti (Platyhelminthes : Cestoda)
(Elsevier B.V., 2006-03-01)Parasitic flatworms present several steps of body architecture rearrangement during their fast transition from one developmental stage to another, which are, at least in part, responsible for their evasion from host immune ...
