What are 5 parasites found in sputum?

Five parasites that can be found in sputum include Paragonimus westermani, Strongyloides stercoralis, Ascaris lumbricoides, hookworm, and Entamoeba histolytica. Microscopic examination of sputum is used to identify these parasites (Reference: Microscopic examination of sputum is used in identifying Paragonimus westermani eggs, Strongyloides stercoralis larvae, Ascaris lumbricoides larvae, hookworm larvae, and rarely Entamoeba histolytica).

Parasites Found in Sputum

Sputum, the mucus expelled from the lungs, can harbor various parasites, indicating pulmonary involvement in parasitic infections. Identifying these parasites through microscopic examination of sputum is crucial for diagnosis and treatment.

Here's a breakdown of five parasites that can be found in sputum:

• Paragonimus westermani: This lung fluke causes paragonimiasis. Diagnosis is often made by finding eggs in the sputum.

• Strongyloides stercoralis: While typically associated with intestinal infection, Strongyloides larvae can migrate to the lungs, especially in cases of hyperinfection. Larvae can be found in sputum samples.

• Ascaris lumbricoides: During the migratory phase of Ascaris infection, larvae travel through the lungs. Sputum samples may contain Ascaris larvae during this period.

• Hookworm: Similar to Ascaris, hookworm larvae also migrate through the lungs as part of their life cycle. Therefore, hookworm larvae can sometimes be identified in sputum.

• Entamoeba histolytica: Though rare, Entamoeba histolytica, typically known for causing amoebic dysentery, can lead to lung abscesses, and in such cases, the trophozoites of E. histolytica may be found in the sputum.
