  2. Definition • Human parasitic disease caused by nematode S. Stercoralis. • Mostly in tropical, subtropical area and temperate climate. • Affect 30-100 million annually. • Has two unique life cycle: Free life cycle and Parasitic life cycle.

  3. Definition • Cause by direct contact with contaminated soil and recreational activities. • Children highly affected to bad sanitation. • S. stercoralis is a 2 mm long intestinal worm

  4. Rhabditiform (L1) larva of Strongyloides stercoralis is about 0.3 mm long. (1 µm = 0.001 mm)

  8. Life Cycle

  9. Pathology • Invasive : Skin Penetration. • Pulmonary: During Cycle or Immigration. • Intestinal: Tissue Destruction

  10. Symptoms and Signs of Hyperinfection • anemia (for example, pale skin) • constipation • cough • diarrhea • eosinophilicpneumonitis (during larvae migration through the lungs) • Nausea • vomiting • weight loss.

  11. Symptoms of Immunosuppressed patients (organ transplant) or immunocompromised patients (HIV): • Death • neurological and pulmonary complications • shock.

  12. Diagnosis • Stool culture most effective way. • Confusion diagnosis arise day-to-day variability number of juvenile worm.

  13. Treatment • Strongyloidiasis is treated with: • Ivermectin. • Tthiabendazole. • No public health strategies for controlling are active at global level.

  14. Control • Good sanitation with specific care of human waste disposal. • Mass treatment of Ivermectin drugs shows some progress but needs further research. • Setting global health plan. • Wearing permanent shoes. • Education Program for community.

  15. discussion • How many people affected yearly. • Is it one of the neglected WHO diseases. • How many life cycle does it have. • Where it is the main host in human body. • What is the name of the drug treat. • One of the best way to control.
