Parasitic Worms
These animations, from the Wellcome Trust, help to show how parasitic worms are a major public health problem.
Thriving in numerous parts of the world associated with poor sanitation or water, these parasites have devised ingenious mechanisms that allow them to enter the human body, resulting in serious disease.
The animations show how the following diseases are transmitted and the effects they have in the body:
• Intestinal Worms
• Lymphatic Filariasis
• Schistosomiasis
HEALTH and SAFETY
Any use of a resource that includes a practical activity must include a risk assessment.
Please note that collections may contain ARCHIVE resources, which were developed at a much earlier date.
Since that time there have been significant changes in the rules and guidance affecting laboratory practical work.
Further information is provided in our Health and Safety guidance.
Intestinal Worms
From the Wellcome Trust, this animation shows how environment and living conditions can lead to infection by a range of energy sapping intestinal worms. The three main worms infecting humans are hookworm, roundworm and whipworm. The animation shows how these parasites can be transmitted in areas where soil is contaminated with…
Lymphatic Filariasis
Produced by the Wellcome Trust, this animation shows the complete life cycle of tiny parasitic worms as they move between human and mosquito hosts. Lymphatic filariasis is a disabling disease found in low-income areas of many tropical and subtropical countries. Parasitic worms multiply in the lymphatic system and release larvae…
Schistosomiasis Life Cycle
This animation, from the Wellcome Trust, illustrates how several species of the Schistosoma parasitic worms exploit humans and fresh water snails. The parasites use rivers and streams to transfer between the two animals, using each for a specific phase of its life cycle. The parasitic worms are able to penetrate skin and infect…
