“…In Türkiye, the presence of protozoan parasites in different water sources has been revealed through various studies. In these studies, protozoa such as G. intestinalis, C. parvum and T. gondii have been investigated more than E. histolytica [2,3,[27][28][29][30][31][32]. In contrast, it has been observed in the literature search conducted that the number of studies conducted on E. histolytica in waters in Turkey is quite limited, and it has been observed that E. histolytica presence was detected only in one study [33].…”

Purpose This study was carried out to determine the prevalence of Entamoeba histolytica in water sources of Niğde province in Türkiye, between June and November 2021. Methods A total of 90 water samples were taken from 15 different water sources (drinking water, well water, spring water, wastewater and dam water) every month and the presence of E. histolytica antigens in the samples was examined by ELISA. Results The positivity of E. histolytica was determined in 7 (7.7%) of 90 samples. While no parasites were found in any of the samples in June and September, E. histolytica was positive for 3 samples (20%) in July, 1 sample (6.6%) in August and October and 2 samples in November (13.3%). One of 24 dam samples (4.1%), 1 of 12 wastewater samples (8.3%), 1 of 12 well samples (8.3%), and 4 of 24 fountain samples (16.6%) that examined by ELISA were found positive. On the other hand, none of the examined 18 spring samples were positive. In addition, 4 (8.8%) of 45 samples that examined in summer and 3 (6.6%) of 45 samples that examined in autumn were detected positive by using ELISA. Entamoebahistolytica positivity in samples was statistically insignificant in terms of months, water resources and seasons (P>0.05). Conclusion As a result, the presence of E. histolytica, which is an important public health problem in water sources, was determined for the first time in Niğde province of Türkiye with this study.

“…Thus, in addition to contributing to human infection through direct consumption, water is likely an important vehicle for indirect transmission through the application of contaminated irrigation water to produce intended for raw consumption. There have been recent findings of C. cayetanensis in wastewater, some watersheds, and other sources of water, particularly agricultural water [ 22 , 76 , 77 , 78 , 79 , 80 , 81 , 82 , 83 ], that reinforce the contribution of humans to water contamination. The fact that contaminated water might be used for irrigation of produce and, therefore, contaminate produce, supports the importance of future studies focused on understanding the role of agricultural water in the transmission of the parasite.…”

Cyclospora cayetanensis infections are prevalent worldwide, and the parasite has become a major public health and food safety concern. Although important efforts have been dedicated to advance toward preventing and reducing incidences of cyclosporiasis, there are still several knowledge gaps that hamper the implementation of effective measures to prevent the contamination of produce and water with Cyclospora oocysts. Some of these data gaps can be attributed to the fact that access to oocysts is a limiting factor in C. cayetanensis research. There are no animal models or in vivo or in vitro culture systems to propagate the oocysts needed to facilitate C. cayetanensis research. Thus, researchers must rely upon limited supplies of oocysts obtained from naturally infected human patients considerably restricting what can be learnt about this parasite. Despite the limited supply of C. cayetanensis oocysts, several important advances have happened in the past 3 years. Great progress has been made in the Cyclospora field in the areas of molecular characterization of strains and species, generation of genomes, and development of novel detection methods. This comprehensive perspective summarizes research published from 2020 to 2023 and evaluates what we have learnt and identifies those aspects in which further research is needed.
