ABSTRACT
The study describes the intensity and histopathology of the Clinostomum complanatum infection in Garra rufa used in the health and beauty industries in foot spas for ichthyotherapy. In total of 25 examined fish specimens 56% were infected with the metacercariae of C. complanatum. The mean intensity of the infection was 27.14 cysts per host, varying between 1-75 cysts. The parasites were determined encysted in the base of the fins, muscle, inner wall of the operculum, gill arches, lips, upper jaw, body cavity and palate, forming small 2-3 mm diameter white-yellowish nodules, easy to detect in macroscopical observation. The highest prevalence of the metacercariae was in C. complanatum with 59.73% in gill tissue. The parasites were found encapsulated by a thin connective tissue each containing a single parasite in muscle. Mercariae of C. complanatum were caused necrotic and fibrotic muscle tissues lesions in Garra rufa.
