What is the Infective stage of the following parasite? Trichinella spiralisCapillaria philipinensis
encysted larvae
Trichinella spiralis:
The infective stage of Trichinella spiralis is the muscle larvae (also known as juveniles) which are formed after the adult female worms release their larvae in the small intestine. These larvae then migrate through the bloodstream, eventually reaching the muscles where they encyst and become infectious. When consumed by a new host, the larvae are released from their cysts and can start the cycle over again.
Capillaria philippinensis:
The infective stage of Capillaria philippinensis is the embryonated egg. These eggs are excreted in the feces of infected individuals and can survive in water for several weeks. When ingested by a new host, they hatch and release immature larvae which migrate to the intestinal mucosa where they mature into adults and begin producing eggs. These eggs are then excreted, continuing the cycle.
