The infection occurs partly directly partly via intermediate hosts, e.g. The first intermediate host is a Cyclops in which the procercoids are found and the second intermediate host comprises of frogs, snakes, birds and mammals in which the spargana is found. Humans acquire the infection by consuming raw or undercooked freshwater fish. The long first antennae, 2 in number, are used by the males for gripping the females during mating. Afterwards, the female carries the eggs in two small sacs on her body. The larvae, or nauplii, are free-swimming and unsegmented. Cyclops has a cosmopolitan distribution in fresh water, but is less frequent in brackish water. snails in trematodes. The life cycle is a three host-system: a snail is always the first intermediate host, a freshwater fish is normally the second intermediate host, and there is a wide range of definitive hosts. A reservoir host is an animal which takes the place of man in the life cycle of a parasite, e.g., Antelope is the reservoir host of African Trypanosomiasis. It is also a common intermediate host of cestode parasites, such as Schistocephalus solidus.

The following cyclopoid copepods were employed as experimental intermediate hosts of Ph. Following ingestion of the Cyclops by a fish, frog or snake (second intermediate host), the L2 develops in their flesh into a L3. In Lake Grundlsee procercoids of T. crassus, T. nodulosus and Eubothrium salvelini use the copepod Cyclops abyssorum praealpinus as … The second intermediate hosts for D. latum are freshwater fish such as trout, pike, turbot, and perch; D. nihonkaiense is found in salmon species in the Pacific Ocean; D. pacificum is found in marine fish from the Pacific coast of South America, and larvae of D. dendriticum have been reported in Atlantic salmon and whitefish. Maturation and hatching of eggs took 6 to 12 days by incubation at temperature 30ºC. When the second intermediate host is ingested by a definitive host, the third-stage larvae develop into adult parasites in the stomach wall .
