Study Notes
Campylobacter Overview
- Campylobacter is a genus of bacteria known for causing gastrointestinal infections in humans.
- It is a Gram-negative, spiral-shaped, and motile bacterium.
Common Pathogens and Sources
- Campylobacter jejuni is the most common species responsible for human disease.
- Common sources include undercooked poultry, unpasteurized milk, and contaminated water. Some food items are not typically associated with Campylobacter.
Growth and Environment
- Optimal growth temperature for Campylobacter is between 37°C and 42°C, with preference for microaerobic conditions.
- Campylobacter is sensitive to acidic environments, such as the stomach's hydrochloric acid.
Symptoms and Transmission
- Symptoms include diarrhea, abdominal pain, fever, and nausea.
- Common transmission routes are through contaminated food or water.
Risk Factors
- Young children, the elderly, and immunocompromised individuals are particularly at risk for severe illness or complications.
- Certain medications, such as antacids or proton pump inhibitors, may increase the susceptibility to infection.
Incubation and Duration
- The incubation period for Campylobacter infection ranges from 2 to 5 days.
- Typical duration of symptomatic infection is about 1 week; antibiotic treatment is generally effective for non-complex cases, potentially reducing symptoms.
Diagnostic and Treatment
- Campylobacter Blood Agar (CVA) is used for culturing these bacteria.
- Antibiotic susceptibility testing is essential to guide treatment choices.
- Drugs of choice for high-risk patients include macrolides (e.g., azithromycin) and fluoroquinolones.
Complications
- Campylobacter is the most common trigger for Guillain–Barré syndrome, a rare neurological disorder.
- In cases of systemic infection, bactericidal antibiotics are administered.
Prevention Measures
- Preventative measures include proper food handling, cooking meat thoroughly, and avoiding unpasteurized dairy products.
