The oocyst, a resistant form of Toxoplasma gondii, plays an important role in the transmission of this protozoan. The objective of this review was to report the methods capable of inactivating oocysts through a systematic review of the literature carried out in the Scientific Electronic Library Online, Web of Science, Science Direct, PubMed and Scopus databases. The keywords searched were (((effects OR infectivity OR resistance) AND Toxoplasma) AND oocyst). We selected 16 articles that described 309 different treatments. Among all the protocols evaluated, 35.60% (110/309) were effective in inactivating oocysts. Physical methods were more effective than other methods (p <0.05). Sporulated oocysts and the T. gondii VEG strain were more resistant (p <0.05) to treatments. Although it is effective against viruses and bacteria, the use of disinfectants in water has little or no effect on T. gondii oocysts. The use of radiation and pressure were effective in inactivating oocysts, as these treatments do not include changes in temperature, they can be used in foods for raw consumption, such as vegetables, as it will not cause substantially changes in their physical and chemical characteristics. Therefore, these methods can be viable alternatives for the control of T. gondii.
卵囊是刚地弓形虫的一种抗性形式，在这种原生动物的传播中起着重要作用。本综述的目的是通过在科学电子图书馆在线、Web of Science、Science Direct、PubMed 和 Scopus 数据库中进行文献系统综述，报告能够使卵囊失活的方法。搜索的关键词是（（（（效果或传染性或抗性）和刚地弓形虫）和卵囊）。我们选择了 16 篇描述了 309 种不同处理方法的文章。在所有评估的方案中，35.60%（110/309）有效地使卵囊失活。物理方法比其他方法更有效（p<0.05）。孢子化卵囊和刚地弓形虫 VEG 株对处理更具抗性（p<0.05）。尽管它对病毒和细菌有效，但消毒剂在水中对刚地弓形虫卵囊的影响很小或没有。辐射和压力的使用对卵囊的失活有效，因为这些处理不包括温度变化，它们可以用于生食的食品中，如蔬菜，因为它们不会导致其物理和化学特性发生实质性变化。因此，这些方法可以作为控制刚地弓形虫的可行替代品。
