Study Notes
Pathogens and Diseases
- A pathogen is a microorganism that causes disease.
- Examples of pathogens are viruses, bacteria, fungi, and protists.
- Malaria is a disease caused by a protist.
- Mosquitoes are vectors that spread the malaria protist.
- The malaria protist reproduces rapidly inside the human body.
Malaria Transmission
- The malaria protist's life cycle involves sexual and asexual reproduction.
- The sexual stage occurs in mosquitoes, and the asexual stage occurs in humans.
- Mosquito bites transmit the malaria protist from one person to another.
- The mosquito acts as a vector, transmitting the pathogen.
Malaria Symptoms
- Common symptoms include: headache, fatigue, nausea, vomiting, chills, fever, and muscle aches, and can be fatal.
- Repeated fevers are a possible symptom.
Malaria Prevention
- Draining stagnant water can reduce mosquito breeding sites.
- Using mosquito nets prevents mosquito bites.
Antibiotics and Malaria
- Antibiotics are ineffective against protist pathogens, such as those that cause malaria.
Pathogen Classification
- Viruses are one type of pathogen.
- Bacteria are another.
- Fungi (e.g., athlete’s foot) are also pathogens.
- Protists (e.g., malaria) are a type of pathogen.
- A house fly is not a pathogen because it is not a microorganism.
Microorganism Classification
- Pathogens are microscopic organisms (e.g., viruses, bacteria, fungi, protists).
