Differentiating Ascaris from other Nematodes[1] | ||||||
---|---|---|---|---|---|---|
Nematode | Transmission | Direct Person-Person Transmission | Duration of Infection | Pulmonary Manifestation | Location of Adult worm(s) | Treatment |
Ascaris lumbricoides | Ingestion of infective ova | No | 1-2 years |
|
Free in the lumen of the small bowel
(primarily jejunum) |
|
Trichuris trichiura
(whipworm) |
Ingestion of infective ova | No | 1-3 years | No pulmonary migration, therefore, no pulmonary manifestation | Anchored in the superficial mucosa of cecum and colon |
|
Hookworm (Necator americanus and Ancylostoma duodenale) | Skin penetration by filariform larvae | No |
|
|
Attached to the mucosa of mid-upper portion of the small bowel |
|
Strongyloides stercoralis | Filariform larvae penetrates skin or bowel mucosa | Yes | Lifetime of the host |
|
Embedded in the mucosa of the duodenum, jejunum |
|
Enterobius vermicularis (pinworm) | Ingestion of infective ova | Yes | 1 month | No pulmonary migration, therefore, no pulmonary manifestation | Free in the lumen of cecum, appendix, adjacent colon |
