|A behavior of eating arthropod intermediate host, the cockroaches and beetles.
||Acanthocephala (a distinct phylum characterized by thorn headed worms) are zoonotic parasites that require at least two hosts to complete their life cycle,  an arthropod intermediate host and a mammal definitive host.  Human infection is rare and accidental,  and happens by ingesting the arthropod intermediate host.      
|Diarrhea, usually blood stained.
||It is due to mechanical damage caused by the insertion of the armed proboscis into the lumen of the host's intestine.  
|Passage of adult worms with stools.
||Some reports show cases with parasitic infestation with no symptoms.  However, some of the cases were identified after the patient has been passing adult worms in stools. Morphological assessment of the worms assist in diagnosing.     
|Non-specific abdominal pain, nausea, vomiting and anorexia
||Majority of the cases reported milder non-specific gastrointestinal symptoms, in some symptoms have been there for months before arriving at a diagnosis. 
||Abdominal distention or edema has been reported in several cases but in some there was co-existent other parasitic gastroenteritis types. 
||It is due to inflammatory response to the parasitic infection.
