Blood Flukes Unveiled: Schistosoma Mansoni and Haemotobium – A Comparative Overview

Introduction to Schistosoma Mansoni and

Haemotobium

Schistosoma Mansoni and

Haemotobium, commonly known as blood flukes, are parasites that infect humans. They are the primary cause of schistosomiasis or snail fever, a tropical disease that affects millions of people worldwide.

In this article, we will delve into the basics of Schistosoma Mansoni and

Haemotobium, their pathogenesis, clinical findings, and laboratory diagnosis, with the aim of providing readers with an overview of these parasites, including their similarities and differences.

Overview and Key Difference

Schistosoma Mansoni and

Haemotobium are both trematodes or flatworms that parasitize humans. They are acquired through skin penetration when individuals come into contact with contaminated freshwater bodies.

The eggs of the parasites are excreted in human feces or urine, where they hatch and release miracidia, the first larval stage. Miracidia infect freshwater snails, where they develop into cercariae, the second larval stage.

The cercariae then penetrate the skin of individuals in contact with the contaminated water and develop into schistosomula, which migrate to the liver, lungs, and other organs via the circulation. The parasites then mate and lay eggs, which can cause significant damage to various organs.

Schistosoma Mansoni primarily affects the gastrointestinal system, causing hepatomegaly, portal hypertension, splenomegaly, and distal colon damage. It is endemic in sub-Saharan Africa, Brazil, and parts of the Middle East.

On the other hand,

Haemotobium affects the urinary tract, causing infections that can lead to bladder cancer and renal failure. It is endemic in sub-Saharan Africa and the Middle East.

Definition of Schistosoma Mansoni and

Haemotobium

Schistosoma Mansoni is a species of trematode or blood fluke that primarily affects the gastrointestinal system. It is endemic in sub-Saharan Africa, Brazil, and parts of the Middle East.

The adult parasite is a flatworm that lives in the mesenteric veins that drain the large intestine. Schistosoma Mansoni eggs cause significant damage to various organs, leading to hepatomegaly, portal hypertension, splenomegaly, and distal colon damage.

Haemotobium, also known as urinary schistosomiasis, is a species of trematode or blood fluke that primarily affects the urinary tract. The adult parasite is a flatworm that lives in the venous plexus around the bladder, ureters, and renal pelvis.

Haemotobium eggs can cause damage to the urinary tract and are responsible for bladder cancer and renal failure.

Haemotobium is endemic in sub-Saharan Africa and the Middle East.

Pathogenesis of Schistosoma Mansoni

Schistosoma Mansoni eggs are the primary cause of pathology. The eggs are excreted in the feces, which hatch in freshwater bodies and infect snails.

The cercariae develop from the snails, penetrate the skin of individuals in contact with contaminated water, and migrate through the circulation to the liver and lungs. The schistosomula then migrate to the portal system, where they develop into adult worms that mate and lay eggs.

Eggs that are not excreted from the body are trapped in the liver or other organs, where they induce a granulomatous reaction that leads to fibrosis. This fibrosis can cause portal hypertension and hepatosplenomegaly.

The eggs can also break through the walls of the portal system, leading to the formation of varices and subsequent bleeding. In addition, the eggs that penetrate the intestinal and bladder walls cause inflammation and ulceration.

This can lead to distal colon damage and bladder cancer, respectively.

Clinical Findings of Schistosoma Mansoni

Schistosoma Mansoni infection can present with a wide range of clinical findings. Symptoms can vary from mild to severe and depend on the number of parasites present in the body and the immune response of the host.

Clinical findings can include itching and dermatitis at the site of skin penetration, fever, chills, diarrhea, and lymphadenopathy. In severe cases, massive splenomegaly, ascites, and esophageal varices can also occur.

Laboratory Diagnosis of Schistosoma Mansoni

Laboratory diagnosis of Schistosoma Mansoni involves identifying the parasite’s eggs in stool or urine samples. The eggs are observed under a microscope and appear elongated with a lateral spine.

Praziquantel is the drug of choice for the treatment of Schistosoma Mansoni infection.
