In severe cases, the young puppy or kitten can bleed to death. These animals are growing, and growth includes making enough new blood to nourish the entire body as well as provide extra oxygen needed to grow, which requires a lot of blood production from the immature animal’s bone marrow, yet in the hookworm-infected puppy this process is being sabotaged by the hookworms. Hookworm infection can be especially bad to the young puppy or kitten. 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. The pet can be infected from contaminated dirt or by eating an infected animal or insect, including a cockroach.The egg hatches in the environment and develops from a first stage larva (the hatchling) to a second stage larva and lastly a third stage larva, which is ready to infect a new host. Another way for the larva to gain entry to the new host is to be licked up and swallowed by the host as it cleans itself.

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. Hookworm eggs are passed into the world mixed through the host animal’s feces. The adult worm lives and mates within the host’s intestine and ultimately, the female produces eggs. This means that, like other parasitic worms, they are bathed in intestinal nutrients but while other worms take the host’s food by absorbing it through their skin, hookworms feed by drinking their host’s blood.

Other current activities include stability testing for both Na-GST-1 and Na-APR-1.The adult hookworm lives in the small intestine of its host where it hangs on to the intestinal wall using its teeth-like structures.

Safety and Immunogenicity of the Human Hookworm Candidate Vaccine Na-GST-1 With Different Doses of a Novel Adjuvant Na-GST-1 study record details Na-APR-1 study record detailsĬurrently researchers at George Washington University are conducting a challenge test to determine the efficacy of Na-GST-1, infecting hookworm-naïve adults with hookworm larvae. Na-GST-1 and Na-APR-1 have completed Phase 1, first-in-humans safety trials, becoming the first-ever hookworm vaccines to complete clinical trials. Monovalent vaccines developed by our researchers with Na-GST-1 and Na-APR-1 as single antigens are currently undergoing various Phase 1 clinical trials. The vaccine will be comprised of two recombinant antigens, Na-GST-1 and Na-APR-1, enzymes involved in the parasite's digestion of host blood. Researchers at our laboratories are developing a bivalent hookworm vaccine that will provide protection against Necator americanus, an intestinal parasite that infects hundreds of millions of people worldwide.
