What causes malaria African sleep sickness and amoebic dysentery?

Answer 1

Well first thing first malaria and African sleeping sickness are to different things.

Malaria is caused by a parasite that is transmitted from one human to another by the bite of infected Anopheles mosquitoes. It involves high fevers, shaking chills, flu-like symptoms, and anemia. The parasites multiply inside the red blood cells, which then rupture within 48 to 72 hours, infecting more red blood cells. The first symptoms usually occur 10 days to 4 weeks after infection, though they can appear as early as 8 days or as long as a year after infection. Then the symptoms occur in cycles of 48 to 72 hours.

Human African trypanosomiasis (HAT), also called sleeping sickness, is an illness endemic to sub-Saharan Africa. these parasites are transmitted to human hosts by bites of infected tsetse flies which are found only in Africa.

The disease is mostly transmitted through the bite of an infected tsetse fly but there are other ways in which people are infected with sleeping sickness.

• Mother-to-child infection: the trypanosome can cross the placenta and infect the fetus.
• Mechanical transmission through other blood sucking insects is possible. However, it is difficult to assess the epidemiological impact of transmission.
• Accidental infections have occurred in laboratories due to pricks from contaminated needles.

Amoebic dysentery (amoebiasis) is an infection of the intestine (gut) caused by an amoeba called Entamoeba histolytica that, among other things, can cause severe diarrhoea with blood.

But it may cause milder chronic symptoms of:

• frequent loose stools
• abdominal pain
• cramps
• fatigue
• intermittent constipation
• diarrhoea with abdominal swelling
• flatulence.

Amoebae are parasites that are found in contaminated food or drink. They enter the body through the mouth when the contaminated food or drink is swallowed.

The amoebae are then able to move through the digestive system and take up residence in the intestine and cause an infection.

Answer 2

Malaria is caused by Plasmodium. African sleeping sickness is caused by Trypanosoma. Amoebic dysentery is caused by Entamoeba hystolytica. All the three pathogens are protozoa and belongs to animal kingdom.
