The puppy may effectively bleed to death. Growing requires a tremendous red blood cell production from the puppy’s bone marrow, yet in the hookworm-infected puppy this process is being sabotaged by numerous tiny vampires within. A young puppy is growing, and growth includes making enough new blood to serve not only its current oxygen needs but what is required for growth as well.
Hookworm infection can be looked at as a natural check in the canine population as it is frequently lethal to young puppies. Now let's return to the points we want to emphasize. If the pet eats an infected rodent or bird, the pet will become infected just the same as if the infection came directly from the soil. Other vertebrates, such as rodents and birds, can pick up hookworm larvae from the soil. It is worth repeating that the host is not always a pet. The developing larvae may migrate widely through the new host's body before settling down to complete their maturation. Their eggs are passed by the host into the environment where a new host picks them up. Summary: The adult worms live by sucking blood from the intestine. These larvae remain inactive, periodically emerging and continuing their migration. As they emerge from one tissue to move on to the next, some fall into a state of arrest where they go dormant and encyst. Not all the worms that begin this treacherous migration complete it. Once back in the intestine, these well-traveled worms will complete their maturation to adulthood, rejoining any friends they had that never left the intestine on a migration. In the lung, the larvae develop into fourth stage larvae, and when they are ready they break out of the lung, climb up the trachea (windpipe), get coughed into the throat, and swallowed. Other individuals are bolder, tunneling out of the intestine and migrating to the lung tissue. Once the larvae are inside the host, they make their way to the intestine where some worms simply stay and mature into adulthood. This could be a prey animal, such as a rodent, or could be an insect such as a cockroach. The pet can be infected from contaminated dirt or by eating an infected animal. Another way for the larva to gain entry to the new host is to be in soil that is licked and swallowed by the host as it cleans itself.
#Hookworms in humans contagious skin
One way is to penetrate the host's skin directly through the feet or belly or whatever part of the skin is touching the ground. The larva can infect its new host in several ways. The egg hatches in the environment and develops from a first stage larva (the hatchling) to a second stage larva and finally a third stage larva, which is ready to infect a new host. Hookworm larvae can be swallowed when the dog licks contaminated dirt from his feet.
