However, PZQ does not prevent re-infections, has a limited effect on developed liver and spleen lesions, and is inactive against juvenile schistosomes

Cercarial dermatitis, or swimmer's (duck hunter's) itch, has occurred in seasonal outbreaks in swimmers in freshwater lakes and rivers whose resident or migratory waterfowl are infected with avian schistosomes
The massive egg production of schistosomes
is leading to granuloma formation in the gut, intestine, bladder, spleen, liver and lungs (Ross et al.

are parasitic trematode flatworms belonging to the genus Schistosoma, and like the malarial parasites and the trypanosomes they complete their life cycle and are transmitted from one host to another through an intermediary vector, in this case snails.
Studies on schistosomes
in waterfowl are valuable not only from veterinarian viewpoint but also as a tool to predict the risk of human infection by the schistosome
larval stages (cercariae) which develop in water snails.
In the body, the cercariae develop into adult schistosomes
but do not multiply inside the human body.
INTRODUCTION: The World Health Organization (WHO) estimates that over one billion of the world's population is chronically infested with soil-transmitted helminths and 200 million are Infested with schistosomes
