Match each bacterium with the disease or manifestations it causes.


1. _____ Escherichia coli
2. _____ Klebsiella pneumoniae
3. _____ Proteus mirabilis
4. _____ Salmonella enterica serotype Typhi
5. _____ Shigella flexneri
6. _____ Yersinia pestis


A. Bubonic plague
B. Typhoid fever
C. Gastroenteritis
D. Kidney stones
E. Pus-filled, bloody stools; cramps; fever; and diarrhea
F. Pneumonia

Verified step by step guidance

1. Identify the common diseases or manifestations associated with each bacterium.
2. Match Escherichia coli with its common manifestation, which is often related to gastroenteritis.
3. Associate Klebsiella pneumoniae with pneumonia, as it is a well-known cause of this condition.
4. Link Proteus mirabilis with kidney stones, due to its ability to produce urease, leading to stone formation.
5. Connect Salmonella enterica serotype Typhi with typhoid fever, a systemic infection.
6. Match Shigella flexneri with symptoms of dysentery, characterized by pus-filled, bloody stools, cramps, fever, and diarrhea.
7. Associate Yersinia pestis with bubonic plague, a historically significant disease.

Key Concepts

Pathogenic Bacteria

Pathogenic bacteria are microorganisms that can cause disease in hosts. Understanding the specific pathogenic mechanisms and the diseases associated with different bacterial species is crucial for identifying the correct matches in the question. For instance, Escherichia coli can lead to gastrointestinal issues, while Yersinia pestis is known for causing the bubonic plague.

Disease Manifestations

Disease manifestations refer to the signs and symptoms that result from infections caused by specific bacteria. Each bacterium has characteristic clinical presentations, such as fever, diarrhea, or pneumonia, which help in diagnosing the associated disease. Recognizing these manifestations is essential for accurately matching the bacteria to their respective diseases.

Bacterial Classification

Bacterial classification involves categorizing bacteria based on their characteristics, such as morphology, biochemical properties, and pathogenicity. This classification aids in understanding the relationships between different bacteria and the diseases they cause. For example, knowing that Klebsiella pneumoniae is a common cause of pneumonia helps in linking it to the correct disease manifestation.
