What is the vector for the transmission of malaria?
Anopheles mosquitoes
Anopheles mosquitoes are the only known vectors for malaria transmission.
What type of organism is Plasmodium?
Protoctistan (single-celled) parasites
Plasmodium species are classified as protoctistans.
How does the malaria parasite reproduce in humans?
Asexually
The malaria parasite reproduces asexually in the red blood cells.
What are the primary pathogenic effects of malaria?
Fever, sweating, shaking, muscle pains, headaches
These symptoms result from the rupture of red blood cells by the malaria parasites.
How often do malaria parasites burst out of red blood cells?
Every 2-3 days
This cycle leads to recurring symptoms associated with malaria.
What serious health issues can result from malaria infection?
Liver damage and anaemia
Anaemia occurs due to the destruction of red blood cells, potentially leading to death.
Fill in the blank: The malarial parasite is transmitted to a person from an infected _______.
Anopheles mosquito
What is the first organ that malaria parasites travel to after entering the human body?
Liver
The parasites travel to the liver to mature before entering the bloodstream.
What happens to the parasites after they are released from the liver?
They invade red blood cells
This invasion is crucial for the continuation of the malaria life cycle.
What occurs every 48-72 hours in the life cycle of the malaria parasite?
Parasites reproduce and burst out of red blood cells
This process leads to the symptoms experienced by infected individuals.
What happens to the malaria parasite when a mosquito takes a blood meal from an infected person?
It is transmitted to the mosquito
The mosquito will then undergo further life cycle stages before infecting another person.
True or False: Malaria kills around one million people every year.
True
What is a significant consequence of malaria’s transmission cycle?
Opportunities for mosquitoes to bite infected individuals
This ensures the continuation of malaria transmission in the population.
