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.

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
