Chapter 18: Problem 13

The leading cause of preventable blindness in the world is caused by: (a) Chlamydia trachomatis (b) Haemophilus influenzae (c) Neisseria gonorrhoeae (d) Staphylococcus aureus (e) Streptococcus pneumoniae

Short Answer

Expert verified
Chlamydia trachomatis is the cause of preventable blindness due to trachoma.

Step by step solution

01

Identify the Question

The question asks about the leading cause of preventable blindness. We need to determine which of the given options is responsible for this condition.
02

Analyze Each Option

Ensure you are familiar with each microorganism. Study their associated conditions: - Chlamydia trachomatis is associated with trachoma. - Haemophilus influenzae is related to respiratory infections. - Neisseria gonorrhoeae can cause gonococcal infections, affecting eyes in newborns. - Staphylococcus aureus is known for skin infections. - Streptococcus pneumoniae is a common cause of pneumonia.
03

Focus on Preventable Conditions

Since preventable blindness is the key focus, we need to identify which condition linked to these microorganisms is both a leading cause and preventable. Trachoma, caused by Chlamydia trachomatis, is known as the leading cause of preventable blindness globally.
04

Draw a Conclusion

Based on the analysis, Chlamydia trachomatis is recognized for causing trachoma, a significant cause of preventable blindness. Thus, it stands out from the rest of the options given.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Chlamydia trachomatis
Chlamydia trachomatis is a type of bacteria responsible for several significant human diseases. One of its most critical roles is in causing trachoma, an infectious eye disease. This bacterium can be transmitted through direct personal contact, such as touching an infected person's eye, or through indirect contacts, such as sharing towels or cloths. It is incredibly infectious, especially in areas with limited access to water and sanitation.
  • Chlamydia trachomatis is the most common bacterial cause of sexually transmitted infections.
  • It is also the leading infectious cause of blindness worldwide.
Understanding and controlling the spread of Chlamydia trachomatis is crucial in efforts to prevent related infections and their severe consequences, especially blindness.
Trachoma
Trachoma is an eye infection caused by Chlamydia trachomatis. It starts as a mild infection affecting the conjunctiva and can lead to severe ocular complications if left untreated. The disease progresses slowly and can cause blindness after repeated infections.
Trachoma typically occurs in poor rural communities where access to clean water and health care is limited. The infection leads to the inward turning of the eyelids, causing lashes to scratch the cornea, leading to scarring and eventual blindness.
  • Trachoma is the world's leading cause of preventable blindness.
  • It is endemic in 42 countries, primarily affecting populations in Africa.
The disease is preventable, making education on hygiene and access to clean water essential tools in combating trachoma.
Microorganisms Related to Eye Infections
Several microorganisms, including bacteria, viruses, fungi, and parasites, can cause eye infections. Bacterial infections of the eye can lead to severe outcomes if untreated.
  • Chlamydia trachomatis is predominantly known for causing trachoma.
  • Neisseria gonorrhoeae can cause ophthalmia neonatorum, an eye infection in newborns.
  • Haemophilus influenzae and Streptococcus pneumoniae are less commonly associated with eye infections but can be opportunistic pathogens.
Being aware of these microorganisms is crucial for prompt and effective treatment, which can preserve vision and prevent blindness.
Bacterial Diseases and Blindness Prevention
Preventing blindness caused by bacterial diseases involves a combination of hygiene practices, education, and availability of medical intervention. Understanding the relationship between certain bacteria and the diseases they cause is important to combat visual impairment.
  • Trachoma control strategies include the SAFE strategy:
    1. Surgery for trichiasis (inward turning of eyelashes)
    2. Antibiotics to clear infection
    3. Facial cleanliness to limit transmission
    4. Environmental improvement to reduce flies and improve sanitation
  • Regular eye examinations can identify early signs of bacterial infections.
  • Public health campaigns that promote hygiene and access to clean water are pivotal.
Preventing bacterial-induced blindness requires a concerted effort from healthcare systems and communities.
