Sleeping sickness is also known as trypanosomiasis or African sleeping sickness. It's caused by a small parasite that leads to a serious infection in the brain and the meninges (the covering of the brain and spinal cord) and death if not treated. It is transmitted by the tsetse fly. They usually reproduce through binary fission (dividing into two). Now there is some evidence that they do reproduce sexually as well.

What is a disease caused by Trichinella?

Trichinosis is a disease caused by the parasite Trichinella spiralis. Symptoms can include abdominal pain, diarrhea, fever, and muscle pain. In severe cases, it can lead to complications such as myocarditis or encephalitis.


How can the life cycle and therefore transmission of Trichinella be most easily interrupted?

The life cycle of Trichinella can be interrupted by preventing pigs from eating raw or undercooked meat containing Trichinella larvae. Ensuring proper cooking of pork and wild game meat can effectively kill the larvae, preventing transmission to humans. Additionally, proper hygiene practices when handling and preparing meat can help reduce the risk of transmission.


What is the infective stage of Trichinella spiralis and what disease does it cause?

The infective stage of Trichinella spiralis is the larvae found in undercooked meat, mainly pork. When consumed by humans, these larvae develop into adult worms in the intestines, causing trichinellosis, a disease characterized by symptoms such as muscle pain, fever, and gastrointestinal issues.


What is describe by binary fission?

the way prokaryotes reproduce


Uncooked or undercooked pork may contain?

The traditional answer to this is Trichinella, an internal parasite that can cause severe organ and muscular disease in humans. However, in most first world countries (western Europe, Canada, US, Australia, etc.), this parasite is no longer a concern as food safety and meat inspection services have controlled or eradicated this parasite.In developing and undeveloped countries, Trichinella is still a major concern that causes disease annually.
