Study Notes
Types of Pathogens
- Harmful bacteria can cause diseases like pneumonia and strep throat, while antibiotics can treat most bacterial infections.
- Fungi, which cannot produce their own food, feed on organic matter and can cause diseases such as athlete's foot and ringworm.
- Protozoa are complex, one-celled organisms; some act as parasites, stealing nutrients from healthy cells without killing them. Malaria, a serious disease caused by protozoa, is transmitted through infected mosquitoes in tropical areas.
- Pathogens are categorized into four major types: viruses, bacteria, fungi, and protozoa.
Viruses
- Viruses are microscopic, made of genetic material and protein, and are not alive; they can cause illnesses like the common cold, flu, and measles.
- Serious viral diseases include AIDS and hepatitis, with the former being an immune system disorder and the latter affecting the liver.
- Most viral infections are not treatable with antibiotics.
Transmission of Pathogens
- Pathogens spread through four main methods:
- Direct Contact: Touching an infected person, e.g., shaking hands after they cough or sneeze.
- Indirect Contact: Pathogens can be airborne, spreading through sneezes or coughs, or by sharing items such as utensils.
- Contact with Animals or Insects: Vectors like rabid animals and infected insects can transmit diseases such as Lyme disease and malaria.
- Contaminated Food and Water: Foodborne illnesses arise from pathogens in improperly cooked or stored food, emphasizing the importance of proper food handling.
Preventing Infection
- Practicing good personal hygiene, such as handwashing with soap, is crucial to stop the spread of pathogens.
- Maintaining a nutritious diet, adequate sleep, and regular physical activity enhances the body’s ability to fight infections.
- Keeping the living environment clean reduces the presence of pathogens.
Protective Measures
- Avoid close contact with sick individuals, especially those who are contagious.
- Don’t share personal items, including utensils and toothbrushes.
- Always wash hands after using the bathroom, handling pets, or coming in contact with potential sources of pathogens.
- Refrain from touching your face, particularly the mouth, nose, and eyes, to minimize infection risk.
