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…
Leishmaniasis Life Cycle
Leishmaniasis is a disease caused by protozoan parasite transmitted by the sand fly. Two animations, from the Wellcome Trust, show the life cycle of the parasite. They illustrate how the leishmania parasites enter the sand fly and matures in preparation for human infection. The bite from an infected sand fly can lead to disfiguring…
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…
Malaria Life Cycle
From the Wellcome Trust, these animations show the life cycle of the malaria parasite. They illustrate how the parasite develops in the mosquito before being transmitted to a human host following a blood meal. The protozoan then develops inside the host's liver and red blood cells, causing the symptoms of malaria and releasing…
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…
Syphilis
From the Wellcome Trust, this animation shows how syphilis, a sexually transmitted bacterial disease (STD), can infect a person's lymph nodes. If this initial infection is not treated, the bacteria can spread to cause damage to the heart, aorta, brain, eyes and bones. In some cases, untreated syphilis can result in blindness,…
Trypanosomiasis Life Cycle
Two animations, from the Wellcome Trust, illustrate the life cycle of the trypanosomiasis protozoan parasite. They illustrate the journey of these single celled parasites, which cause human African trypanosomiasis or sleeping sickness, from the gut of the tsetse fly into the human bloodstream. If left untreated, the disease can be…
Tuberculosis - Infection and Transmission
From the Wellcome Trust, this animation shows how the human immune system attempts to contain a tuberculosis infection and how the bacteria are transmitted to new people. Tuberculosis usually affects the respiratory system but it can develop in any part of the body. The human immune system commonly contains the infection but a…
Zoom in on Your Genome
Produced by the Wellcome Trust, this animation helps to illustrate where and how the human genome is stored within our cells and bodies. It takes a journey which starts with the whole human body before looking into a liver cell and then the cell's nucleus. The animation shows the arrangements of chromosomes within the nucleus…

Chagas' Disease Life Cycle
From the Wellcome Trust, these animations illustrate the life cycle of the protozoan parasite that causes Chagas' Disease. The parasites use a blood-sucking insect called a triatomine as an incubator and vector. The protozoan parasite mautures and reproduces in the insect before being deposited on humans in the insect’s…
Dengue Virus Replication and Transmission
Produced by the Wellcome Trust, these animations take a detailed look at the molecular mechanisms that allow the dengue virus to subvert the cells of its mammalian host, allowing it to replicate and spread. Dengue is an example of an RNA virus. Being bitten by a mosquito carrying the dengue virus can lead to a broad range of symptoms…
DNA Sequencing
From the Wellcome Trust, these animations show three different methods for the sequencing of DNA. The Sanger method, developed in 1975, illustrates an early way of determining a DNA sequence. Fluorescent bases are incorporated into fragments of DNA that are made from the sample being sequenced. Analysis of the fragments enables…
DNA to Protein - Transcription and Translation
This animation, from the Wellcome Trust, illustrates how the DNA code is used to build protein molecules inside our cells. It shows how, during the process of transcription, polymerase unzips the DNA and uses it as a template to produce a strand of messenger RNA (mRNA) . The animation then goes on to show how this mRNA, along…

HIV Life Cycle
This animation, from the Wellcome Trust, shows how the human immunodeficiency virus (HIV) infects white blood cells and uses its RNA to produce a strand of DNA which becomes integrated in the host cell's genome. HIV replicates inside white blood cells called CD4+ T cells. Here, viral DNA integrates with human DNA and acts…
