Which of the following statements are correct regarding brucellosis? 1. Fever may develop into an undulating pattern that persists for weeks. 2. Associated musculoskeletal symptoms are a feature of the disease. 3. Brucellae behave as facultative intracellular parasites. Select the correct answer using the code given below.
Brucellosis Statements Analysis
To determine the correct statements about brucellosis, let's analyze each point:
- Statement 1: Fever Pattern Brucellosis is well-known for causing a fever that often follows an undulating pattern. This means the temperature rises and falls over periods, sometimes lasting for weeks or even months. This characteristic is a key clinical feature.
- Statement 2: Musculoskeletal Symptoms Musculoskeletal involvement is common in brucellosis. Patients frequently experience symptoms like joint pain (arthralgia), back pain, and arthritis due to the bacteria affecting bones, joints, and muscles.
- Statement 3: Pathogen Behavior Brucella species are classified as facultative intracellular parasites. This means they can survive and multiply both outside the host's cells and within the host's cells, particularly macrophages, which aids in their persistence within the body.
Based on the analysis, all three statements accurately describe aspects of brucellosis. Therefore, the combination including statements 1, 2, and 3 is correct.
