==Overview==
An intestinal parasite infection is a condition in which a [[Parasites|parasite]] [[Infect|infects]] the [[Gastrointestinal tract|gastro-intestinal tract]] of humans and other animals. Mode of transmission of infection can be due to [[ingestion]] of undercooked meat, drinking infected water, fecal-oral transmission and skin absorption. There are many types of parasites that can cause  abdomial infections but the most common parasites responsible for infection include [[Ascaris lumbricoides]], [[Necator americanus]], [[Fasciola hepatica|Fasciola]], [[Schistosoma]], [[Trichuris trichiura]], [[Strongyloides stercoralis]], [[Taenia solium|Taenia,]] [[Hymenolepis infection|Hymenolepis nana]], and [[Entamoeba histolytica]]. Common symptoms of abdominal parasitic infections include are [[abdominal discomfort]], [[anorexia]], [[Nausea and vomiting|nausea]], [[vomiting]], and [[diarrhea]]. [[Stool examination|Stool microscopy]] is the most common diagnostic tool for evaluation.  Common complications include [[Focal neurologic signs|focal neurologic changes]], [[pericarditis]], [[Arrhythmias|arrhythmia]], and right-sided [[pleural effusion]]. [[Serology]] is used as screening mainly because of low sensitivity. [[albendazole]] is the drug of choice for treatment  of most parasitic infections.

Overview

An intestinal parasite infection is a condition in which a parasite infects the gastro-intestinal tract of humans and other animals. Mode of transmission of infection can be due to ingestion of undercooked meat, drinking infected water, fecal-oral transmission and skin absorption. There are many types of parasites that can cause abdomial infections but the most common parasites responsible for infection include Ascaris lumbricoides, Necator americanus, Fasciola, Schistosoma, Trichuris trichiura, Strongyloides stercoralis, Taenia, Hymenolepis nana, and Entamoeba histolytica. Common symptoms of abdominal parasitic infections include are abdominal discomfort, anorexia, nausea, vomiting, and diarrhea. Stool microscopy is the most common diagnostic tool for evaluation. Common complications include focal neurologic changes, pericarditis, arrhythmia, and right-sided pleural effusion. Serology is used as screening mainly because of low sensitivity. albendazole is the drug of choice for treatment of most parasitic infections.

Causes

Abdominal Parasitic infections

The following table summarizes all the abdominal parasitic infections.

  • Stool microscopy
  • PCR, ELISA
Amoebiasis E. Histolytica
