- Diarrhea (initially watery, then bloody and mucoid)
- Dehydration, electrolyte imbalance
Tenderness: Abdominal tenderness, especially in lower left quadrant
Tenesmus: Severe
Macroscopic Stools: Bloody, mucoid stools with rice water appearance
Microscopic Stools:
- Shigella species (gram-negative bacteria)
- Red blood cells
- White blood cells
- Mucus
Amoebic Dysentery
Incubation Period: 7-14 days
Onset: Gradual
Occurrence: Worldwide, but more common in tropical and subtropical areas
Fever: Often low grade or absent
Clinical Picture:
- Abdominal pain, irregular
- Tenesmus (may be less severe than bacillary dysentery)
- Diarrhea (alternating bouts of diarrhea and constipation)
- Weight loss, fatigue
Tenderness: Diffuse abdominal tenderness, especially in right lower quadrant
Tenesmus: May be less severe than bacillary dysentery
Macroscopic Stools: Mucoid, bloody stools with "anchovy paste" appearance
Microscopic Stools:
- Entamoeba histolytica (protozoan parasite)
- Red blood cells
- White blood cells
- Mucus
