## Campylobacter jejuni Infection: Management Strategy ### Clinical Diagnosis Confirmed **Key Point:** The combination of motile comma-shaped gram-negative bacilli, oxidase positivity, and growth at 42°C on selective medium (Campy food agar) definitively identifies *Campylobacter jejuni*. ### First-Line Antibiotic Choice **High-Yield:** Azithromycin (a macrolide) is the preferred empiric antibiotic for *Campylobacter* gastroenteritis in most settings, including India, because: - Excellent intracellular penetration into intestinal mucosa - Effective against both susceptible and fluoroquinolone-resistant strains - Shorter duration (3 days) reduces antibiotic exposure - Lower resistance rates compared to fluoroquinolones in developing countries ### Why Azithromycin Over Alternatives | Feature | Azithromycin | Ciprofloxacin | Tetracycline | |---------|--------------|---------------|---------------| | **Resistance** | Low (5–10%) | High (20–40% in India) | Moderate | | **Tissue penetration** | Excellent | Good | Good | | **Dosing duration** | 3 days | 5–7 days | 5–7 days | | **GI side effects** | Moderate | Moderate | High | | **Cost** | Moderate | Low | Low | **Clinical Pearl:** Fluoroquinolone resistance in *Campylobacter* is now endemic in India and many developing nations; ciprofloxacin should be reserved for susceptibility-guided therapy only. ### Timing of Antibiotics **Key Point:** Early antibiotic therapy (within 3 days of symptom onset) shortens duration of diarrhea and reduces bacterial shedding. This patient is at day 21, but antibiotics still reduce symptom duration and prevent complications. ### Supportive Care **Warning:** Do NOT withhold antibiotics in moderate-to-severe disease. Oral rehydration with electrolyte solutions is concurrent, not alternative, to antimicrobial therapy.
