Things worth knowing about "Amoebic Dysentery"
Amoebic dysentery is an intestinal infection caused by the parasite Entamoeba histolytica, leading to bloody diarrhea, abdominal cramps, and fever.
What Is Amoebic Dysentery?
Amoebic dysentery is an infectious disease of the intestine caused by the single-celled parasite Entamoeba histolytica. It is one of the most significant parasitic causes of diarrheal illness worldwide, primarily affecting people in tropical and subtropical regions where access to clean drinking water and adequate sanitation is limited.
Causes and Transmission
The parasite Entamoeba histolytica is transmitted via the fecal-oral route. Common sources of infection include:
- Drinking contaminated water
- Eating raw or unwashed fruits and vegetables
- Poor hand hygiene, especially after using the toilet
- Direct contact with infected individuals
The parasite enters the digestive tract as hardy cysts, transforms into active trophozoites in the intestine, and invades the gut wall, causing ulcers and inflammation.
Symptoms
The incubation period is typically one to four weeks. Common symptoms of amoebic dysentery include:
- Bloody or mucus-containing diarrhea (multiple times daily)
- Severe, cramping abdominal pain
- Painful urge to defecate (tenesmus)
- Nausea and vomiting
- Low-grade fever
- General fatigue and weakness
In severe cases, the infection can spread beyond the intestine. A particularly serious complication is the amoebic liver abscess, in which pus accumulates in liver tissue, causing high fever and intense pain in the upper right abdomen.
Diagnosis
Amoebic dysentery is diagnosed using several methods:
- Stool examination: Microscopic detection of cysts or trophozoites in stool samples
- Antigen testing: Detection of Entamoeba histolytica antigens in stool via ELISA
- Serology: Blood tests to detect antibodies against the parasite, especially in cases of extraintestinal spread
- PCR testing: Molecular detection of the parasite in stool
- Imaging: Ultrasound or CT scan to identify liver abscesses
Treatment
Treatment depends on the severity of the infection:
Medication
- Metronidazole or Tinidazole: First-line treatment for active, invasive intestinal and hepatic amoebiasis
- Paromomycin or Diloxanide furoate: Used to eliminate intestinal cysts following treatment with metronidazole
Supportive Care
- Adequate fluid intake to replace fluids and electrolytes lost through diarrhea
- In severe cases, hospital admission and intravenous fluid replacement may be necessary
Prevention
The following precautions are recommended to prevent amoebic dysentery, especially when traveling to high-risk areas:
- Drink only boiled or bottled water
- Avoid raw fruits and vegetables that have not been peeled or washed by yourself
- Wash hands thoroughly and regularly with soap
- Avoid street food in regions with poor hygiene standards
