Resumo: AIMS: To review basic aspects on the ultrastructure of the tachyzoite of Toxoplasma gondii, the causative agent of toxoplasmosis. SOURCE OF DATA: The data presented are based on recent publications by the most distinguished research groups in the area dedicated to the study of Toxoplasma gondii, including studies from the present authors. SUMMARY OF FINDINGS: The tachyzoites are responsible for the acute phase of the infection by actively penetrating, through the parasites' apical complex, the host cells where they multiply. Both ultrastructural and molecular particularities of the pellicle, the cytoskeleton, secretory (rhoptries, micronemas and dense granules) and non secretory (apicoplast) organelles, specific to Apicomplexa phylum, besides peculiar features of the nucleus, mitochondrion, acidocalcisomes, endoplasmic reticulum and Golgi complex of these intracellular parasites. CONCLUSIONS: These characteristics confirm that the success in the process of adhesion, invasion and multiplication of Toxoplasma gondii is clearly correlated to its morphology.

FONTE DE DADOS: os dados apresentados tomam como referência resultados recentes obtidos pelos principais grupos de pesquisadores no mundo, que se dedicam ao estudo do Toxoplasma gondii, incluindo-se dados do próprio grupo de autores. SÍNTESE DOS DADOS: os taquizoítos de Toxoplasma gondii são responsáveis pela fase aguda da infecção, penetrando ativamente, através do complexo apical, em células dos hospedeiros onde se multiplicam. São abordadas características ultraestruturais e moleculares particulares da película, do citoesqueleto, de organelas secretórias (róptrias, micronemas e grânulos densos) e não secretórias (apicoplasto) exclusivas do filo Apicomplexa, além das peculiaridades do núcleo, mitocôndria, acidocalcisomas, retículo endoplasmático e complexo de Golgi desses parasitos intracelulares. CONCLUSÕES: estas características confirmam que o sucesso nas etapas de adesão, invasão e multiplicação de Toxoplasma gondii possui clara correlação com suas características morfofuncionais.Editora da PUCRS - ediPUCRS2010-02-22info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfhttps://revistaseletronicas.pucrs.br/scientiamedica/article/view/5957Scientia Medica; Vol. 20 No. 1 (2010): Special issue on Toxoplasmosis; 131-143Scientia Medica; v. 20 n. 1 (2010): Número especial sobre Toxoplasmose; 131-1431980-61081806-5562reponame:Scientia Medica (Porto Alegre.
