What is the Difference Between Schistosoma Mansoni and Haemotobium?

Schistosoma mansoni and Schistosoma haematobium are two distinct species of blood flukes that cause schistosomiasis, a parasitic disease in humans and ruminants. The key differences between these two species lie in their distribution, structure, and effects on the human body.

1. Distribution:

• S. mansoni is principally found in the portal veins draining the large intestine.
• S. haematobium infects veins of the urinary bladder plexus.

1. Egg morphology:

• S. mansoni produces oval eggs (115-175 x 45-7µm) with a sharp lateral spine.
• S. haematobium produces oval eggs (110-170 x 40-70µm) with a sharp terminal spine.

1. Pathology:

• S. mansoni and S. japonicum schistosomiasis can cause hepatic complications, inflammation, granulomatous reactions, and occasional embolic egg granulomas in the brain or spinal cord.
• S. haematobium schistosomiasis can lead to hematuria, scarring, calcification, squamous cell carcinoma, and occasional embolic egg granulomas in the brain or spinal cord.

Although there are differences in egg morphology, growth, and maturation between the two species, the clinical manifestations of schistosomiasis are largely similar, including fever, cough, abdominal pain, diarrhea, hepatosplenomegaly, and eosinophilia. In some cases, Schistosoma infections may also lead to central nervous system lesions.

Comparative Table: Schistosoma Mansoni vs Haemotobium

Schistosoma mansoni and Schistosoma haematobium are two different species of parasitic trematodes (flukes) that cause schistosomiasis, a neglected tropical disease affecting millions of people worldwide. Here is a table highlighting the differences between the two species:

Both Schistosoma mansoni and Schistosoma haematobium infect humans and are transmitted through different snail hosts. S. mansoni is mainly found in snails of the genus Biomphalaria, while S. haematobium is found in snails of the genus Bulinus. These two species contribute to the majority of schistosomiasis cases worldwide.
