Background: Cyclospora cayetanensis is a protozoan parasite causing intestinal infections. A prolonged course of infection is often observed in immunocompromised individuals. In Europe, less than 100 cases of C. cayetanensis infection have been reported to date, almost all of which being diagnosed in individuals after travelling abroad.
Findings: We described cases of three businessmen who developed acute traveller's diarrhoea after they returned to Poland from Indonesia. One of the travellers was a renal transplant recipient having ongoing immunosuppressive treatment. In each case, acute and prolonged diarrhoea and other intestinal disorders occurred. Oocysts of C. cayetanensis were identified in faecal smears of two of the travellers (one immunosuppressed and one immunocompetent). Diagnosis was confirmed by the successful amplification of parasite DNA (18S rDNA). A co-infection with Blastocystis hominis was identified in the immunocompetent man.
Conclusions: Infection of C. cayetanensis shall be considered as the cause of prolonged acute diarrhoea in immunocompromised patients returning from endemic regions.

The migration of Mongolian gazelles () poses a potential risk of outbreak for zoonotic intestinal protozoan parasite infections. This study aims to investigate the infection status of zoonotic intestinal protozoan parasites in these migratory Mongolian gazelles. We collected 120 fecal samples from Mongolian gazelles during their migration from Mongolia to China in December 2023.

Recurring outbreaks of cyclosporiasis linked to fresh produce demonstrate the need to develop interventions to reduce in irrigation water. is resistant to commonly used irrigation water treatments, such as chemical sanitizers, making removal of oocysts by filtration the most suitable intervention. This study evaluated the reduction of and , as surrogates for , in water using filters packed with sand alone or mixtures of sand and zero-valent iron (ZVI).

Berries represent healthy dietary options and contain bioactive compounds associated with a decreased risk of diseases. Despite representing healthy food choices, these products can be contaminated by pathogenic microorganisms, including parasites. Among foodborne parasites, , , , , and are of significant public health importance and have been recently detected in fresh berries in Europe, including Italy.

Article Synopsis
- * Experiments revealed that miniaturized ZVI-sand filters retain 89-99% of oocysts when ZVI concentration is optimized, significantly improving filtration efficacy over traditional methods.
- * ZVI is identified as a highly effective material for reducing contamination risk in agricultural water, with poultry parasites serving as effective surrogates for studying the removal of harmful oocysts.

Article Synopsis
- * A study conducted in Shanxi Province, North China, examined 761 cattle fecal samples for this genus using a specific molecular technique, finding a prevalence of 2.1% without any identified risk factors related to region, age, sex, or breed.
- * The molecular analysis showed that the cattle isolates were genetically distant from the human pathogen, suggesting the need for further research on this genus in humans, other animals, and different locations in Shanxi to understand potential health impacts better.
