Techniques for inactivating Toxoplasma gondii oocysts: a systematic review
Abstract 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.
