Life Cycle Most adult worms are eliminated in 1 to 2 years, but the longevity may reach several years. Some A. duodenale larvae, following penetration of the host skin, can become dormant (hypobiosis in the intestine or muscle). These larvae are capable of re-activating and establishing patent, intestinal infections.
Do hookworms have a direct life cycle?
The life cycle of hookworms is direct (Hoagland and Schad, 1978; Schad and Banwell, 1984). Humans acquire hookworm when the infective larval stages (known as third-stage larvae or L3) living in the soil either penetrate through the skin (both N. americanus and A.
How long does it take for hookworms to mature?
It takes 2-3 weeks for hookworm larvae to mature and begin producing eggs. For this reason, fecal examination may be less reliable in very young puppies than in adult dogs. Adult hookworms are small in size and firmly attach to the intestinal wall, which is why they are rarely detected in stool.
How long do hookworms survive in the environment?
Under optimum conditions, infective larvae may remain viable in the soil for several months or longer, but under natural conditions in the tropics the majority rarely survive longer than five or six weeks.
What is the life cycle of canine hookworms?
The life cycle of the hookworm has three stages: egg, larvae, and adult. The microscopic eggs pass through the feces, where they hatch into larvae and contaminate the environment. The larvae can survive for weeks or even months before infecting your dog.
