Select one of the organisms in this section. Describe the disease it causes, then compare similarities or contrast differences in modes of transmission of the selected organism with any other organism in any other section in this document. Focus on structures, conditions, or behaviors that make disease transmission successful:
Trichomonas causes vaginal inflammation and is primarily transmitted but sexual contact. The other 2 organisms are spead through the tsetse fly or ingestion of fecal matter. Trichomoniasis is one of the most common sexually transmitted diseases. It is a know disease worldwide compared to Trypanosoma which is only found in Arica.

Select one of the organisms in this section. Describe the disease it causes, then compare similarities or contrast differences in modes of transmission of the selected organism with any other organism in any other section in this document. Focus on structures, conditions, or behaviors that make disease transmission successful:
Trichophyton is also known as ringworm and is a common disease. This disease is especially known in the wrestling world. It is spread by body to body contact and bad hygiene. One is more susceptible to ringworm disease if they have a suppressed immune system. Ringworm can be seen in the skin or nails. It appears as an itchy red ring on the skin.

Focus on structures, conditions, or behaviors that make disease transmission successful:
Schistoma japonicum is commonly known as blood fluke. It affects the lungs, live, and urinary bladder or a human or animal. This disease can be transmitted when skin comes into contact with contaminated freshwater. Blood fluke is a disease that occurs all around the world.
