The adult females deposit their eggs in these places which develop into L1 larvae. Similar to the previous case, through coughing, sneezing or expectoration, these larvae can end up in the digestive system and stool of dogs. This can then be ingested by the snails and continue their development into L3 Josie F. Turner. Adult dogs get roundworms from ingesting roundworm larvae, usually from contaminated soil or infected prey (such as a mouse or other small mammal). Puppies are born with roundworms after contracting them from their mother's uterus during gestation. In addition, nursing puppies may ingest roundworm larvae in their mothers' milk.

Normally, adult dogs have some resistance to infection. However, during the period around the birth of a litter, the immunity of the female dog to infection is partially suppressed, and the inactive larvae become active, crossing the placenta to the pups and sequestering in the mammary tissue, where they are transmitted in the colostrum and milk. Nov 12,  · Angiostrongylus cantonensis is a parasitic worm of rats. It is also called the rat lungworm. The adult form of the parasite is found only in rodents. Infected rats pass larvae of the parasite in their feces. Snails and slugs get infected by ingesting the larvae. These larvae mature in snails and.

The parasite's life cycle begins in an infected gastropod, where adult worms produce larvae. The infected gastropods crawl along grassy surfaces or in stagnant water, leaving stool containing larvae behind for dogs or cats to accidentally consume -- or gastropods themselves may be consumed by curious dogs. Jun 20,  · Parasitic worms excreted by snails in water cause schistosomiasis, which leads to bladder bleeding, liver damage, kidney failure, and cancer. Rat lungworms, carried by snails, are transmitted through uncooked snail meat and cause headaches, numbness, and spasms. Avoid raw snail meat and meat from unreliable sources.
