Tachyzoites and bradyzoites
WebMay 1, 2002 · A fundamental difference between tachyzoites and bradyzoites is the resistance of bradyzoites to acid-pepsin digestion, although recent evidence suggests that oral infectivity in mice or acid-pepsin digestion as the sole criterion to distinguish between tachyzoites and bradyzoites cannot be relied on [7].

WebJun 1, 2014 · Tachyzoites divide rapidly within various cells, leading to cell death, tissue necrosis, and granulomatous inflammation. Following acute infection, the organism survives for extended periods in host tissues as slowly dividing bradyzoites within tissue cysts. WebApr 12, 2024 · T. gondii life cycle is considered sexual and asexual with a characteristic complexity; it reproduces sexually in the DH and asexually in the intermediate hosts (IH) with three distinct stages of reproduction: tachyzoites (replicating fast), bradyzoites (replicating slowly), and sporozoites (in sporulated oocysts).

This paper reviews the life cycle; the structure of tachyzoites, bradyzoites, oocysts ... WebTachyzoites multiply rapidly and synchronously, forming rosettes and lysing the cell, whereas the more slowly replicating bradyzoites form tissue cysts. 43 Molecules are expressed in a stage-specific manner and are responsible for certain of the phenotypic differences between tachyzoites and bradyzoites.
WebThese bradyzoite cysts can reconvert back to tachyzoites years later causing serious pathology and death if a person becomes immune-compromised. Like the sexual stage sporozoites, bradyzoites are also orally infectious and a major contributor to transmission.
