Overview
Strongyloidiasis can mimic other worm infections like Ascaris lumbricoides, Trichuris trichiura, hookworm infections (Necator americanus and Ancylostoma duodenale), Enterobius vermicularis (pinworm) and gastrointestinal pathologies such as peptic ulcer disease, intussusception in children, and bile duct stone.[1][2][3]
Differentiating Strongyloidiasis from other diseases
The table below summarizes the findings that differentiate strongyloidiasis from other nematode infections:
Differentiating strongyloidiasis from other Nematode infections[1][2][4] | |||||||
---|---|---|---|---|---|---|---|
Infection | Nematode | Transmission | Direct Person-Person Transmission | Duration of Infection | Pulmonary Manifestation | Location of Adult worm(s) | Treatment |
Strongyloidiasis | Strongyloides stercoralis | Filariform larvae penetrate skin or bowel mucosa | Yes |
|
|
Embedded in the mucosa of the duodenum and jejunum | |
Trichuriasis | Trichuris trichiura
(whipworm) |
Ingestion of infective ova | No | 1-3 years |
|
Anchored in the superficial mucosa of cecum and colon | |
Ascariasis | Ascaris lumbricoides | Ingestion of infective ova | No | 1-2 years |
|
Free air in the lumen of the small bowel
(primarily jejunum) |
|
Hookworm infection | Necator americanus and Ancylostoma duodenale | Skin penetration by filariform larvae | No |
|
|
Attached to the mucosa of mid-upper portion of the small bowel | |
Enterobiasis | Enterobius vermicularis
(pinworm) |
Ingestion of infective ova | Yes |
|
|
Free air in the lumen of cecum, appendix, adjacent colon |
- Strongyloidiasis, when it involves the gastrointestinal tract, presents with abdominal pain and must be differentiated from other GI disorders like peptic ulcer disease, intussusception, and bile duct stone.
- The table below summarizes the findings that differentiate strongyloidiasis from peptic ulcer disease, intussusception, and bile duct stone:
Disease | Common findings | Differentiating features | Laboratory findings |
---|---|---|---|
Peptic ulcer disease |
|
|
|
Intussusception |

|
Bile duct stone |

The table below summarizes the findings that differentiate intestinal strongyloidiasis from other conditions that may cause abdominal pain and diarrhea[5][6][7]
