Following are the diseases caused by salmonella, except?

Appeared in: MNS 2015

Explanation

The question requires identifying the disease not caused by the Salmonella bacterium.
Cholera is an acute diarrheal illness caused by infection of the intestine with the bacterium Vibrio cholerae.
The other options—Diarrhea, Enteric Fever, and Gastroenteritis—are all clinical manifestations or diseases directly caused by various serotypes of Salmonella.
Therefore, Cholera is the correct exception.

Option A: Diarrhea is a primary symptom of Salmonella gastroenteritis, a common infection caused by non-typhoidal Salmonella species.
Option B: Enteric Fever, which includes typhoid and paratyphoid fever, is a severe systemic illness specifically caused by Salmonella Typhi and Salmonella Paratyphi.
Option D: Gastroenteritis, or salmonellosis, is the most common clinical presentation of infection with non-typhoidal Salmonella species.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Causative agents of bacterial gastrointestinal diseases as background academic context rather than a clinical decision trigger.
Differentiating between the causes of acute diarrhea is crucial for patient management. While both Salmonella and Cholera cause diarrhea, the treatment and public health implications differ significantly.
Cholera can cause rapid, severe dehydration, requiring immediate and aggressive fluid and electrolyte replacement. Salmonellosis is often self-limiting, and antibiotics are typically reserved for severe cases or high-risk patients to avoid prolonging the carrier state.
Accurate diagnosis is vital for outbreak control. Identifying the source (e.g., contaminated water for Cholera vs. contaminated food for Salmonella) allows public health officials to implement targeted interventions to prevent further spread.

How to Approach the Question

First, identify the core concept of the question, which is diseases caused by 'Salmonella'.
Next, notice the keyword 'except'. This means you need to find the option that does NOT fit the core concept.
Evaluate each option's relationship with Salmonella.
Recall or deduce that Enteric Fever and Gastroenteritis are classic Salmonella diseases, and diarrhea is a primary symptom.
Identify Cholera as the outlier, as it is a distinct disease caused by a different bacterium (Vibrio cholerae).
Select the outlier as the correct answer.
