Hookworm (55x90cm)

A “Hookworm” (55x90 cm) educational chart visually explains the structure, key species, and life cycle of hookworms, integrating both developmental stages and the infection pathway for biology or health science classrooms.​

Chart Features and Life Cycle Stages

Size and Material: Measures 55×90 cm, typically printed in multicolor on high-quality art paper, thermally laminated for durability and resistance to water, dust, and tears.​

Major Species Covered:

Ancylostoma duodenale and Necator americanus are the primary human-infecting hookworm species.​

Morphology diagrams show the worm's cylindrical body, mouthparts with characteristic hooks or teeth, and comparison with similar parasites.​

Hookworm Life Cycle:

Egg stage: Adult female hookworms release eggs in the host's small intestine, which are excreted with stool into warm, moist soil.​

Larval stage: Eggs hatch in 1-2 days; rhabditiform larvae feed on soil, molt twice in 5–10 days to become infective filariform larvae.​

Transmission: Infective larvae penetrate human skin (often through bare feet), travel via blood to lungs, ascend the trachea, are swallowed, and finally mature into adults in the small intestine.​

Adult stage: Adults anchor to the intestinal wall, feed on blood, and cause anemia and other symptoms. Life expectancy in hosts is 1–2 years.​

Illustrative and Textual Details:

Arrows and stage icons track the entire lifecycle step-by-step.

Brief notes explain pathological effects (blood loss, helminthiasis), host and environmental requirements for transmission, and identification of eggs/larvae in the soil.​

This chart is highly effective for teaching parasitology, microbiology, and public health, helping students visualize hookworm anatomy, transmission, and the impact on human health.
