Metastatic Amoebiasis Model
Product Code : JC-BE-6229
The Metastatic Amoebiasis Model from Jaincolab is an educational chart illustrating how Entamoeba histolytica, having established intestinal infection, can invade the bowel wall, enter the bloodstream, and spread to distant organs to cause serious extraintestinal disease. The model focuses on the most common metastatic complication, amoebic liver abscess, formed when trophozoites travel via the portal venous system to the liver, while also noting rarer spread to the lungs, brain and pericardium.
As a trusted biology lab equipment supplier in India, Jaincolab designs this model to help students of parasitology, pathology and medicine understand the progression from intestinal amoebiasis to life-threatening extraintestinal disease, supporting classroom teaching and laboratory demonstration in microbiology and clinical medicine courses.
What the Concept States
| Parameter | Details |
|---|---|
| Causative Organism | Entamoeba histolytica (invasive trophozoite form) |
| Route of Spread | Trophozoites invade the colonic mucosa and submucosa, enter the portal venous circulation, and are carried to the liver |
| Most Common Metastatic Site | Liver — forming an amoebic liver abscess, typically a single large abscess in the right lobe containing 'anchovy paste' or 'chocolate sauce' coloured necrotic material |
| Rarer Metastatic Sites | Lung (via direct extension or hematogenous spread), brain, and pericardium in advanced or untreated cases |
| Pathological Mechanism | Trophozoites secrete proteolytic enzymes that lyse host tissue, forming a necrotic cavity rather than a typical pus-filled abscess with neutrophils |
| Diagnostic Approach Illustrated | Serology for anti-amoebic antibodies, imaging (ultrasound/CT) of the liver, and correlation with a history of intestinal amoebiasis |
| Clinical Relevance | Amoebic liver abscess is the most frequent and clinically significant extraintestinal complication of Entamoeba histolytica infection |
Key Features
- Clearly labelled illustration of the intestine-to-liver spread route via the portal venous system
- Focused specifically on extraintestinal (metastatic) complications, distinct from intestinal amoebiasis and cyst identification models
- Highlights the distinctive necrotic, 'anchovy paste' character of amoebic liver abscess content
- Durable, classroom- and laboratory-ready construction suitable for repeated use in practical sessions
- Supports parasitology, pathology and internal medicine curricula
- Complements cyst identification and general life-cycle teaching models for a complete amoebiasis teaching set
Why Choose Jaincolab
Jaincolab is a well-established biology lab equipment supplier in India, serving medical colleges and institutions across India and internationally with ISO 9001:2015 and ISO 14001:2015 certified manufacturing. The Metastatic Amoebiasis Model is designed to complement the Cyst of Intestinal Protozoa of Man Model and the Intestinal Protozoa Infection Model, giving institutions a progression from diagnostic identification and intestinal disease through to serious extraintestinal complications. Every model is checked for labelling accuracy before dispatch, helping instructors present amoebiasis pathology with confidence.

Frequently Asked Questions
Q1. What does the Metastatic Amoebiasis Model illustrate?
A. It illustrates how Entamoeba histolytica trophozoites spread beyond the intestine, most commonly to the liver via the portal venous system, causing amoebic liver abscess, with rarer spread to the lungs, brain and pericardium.
Q2. Why does amoebic liver abscess most often affect the right lobe?
A. The right lobe of the liver receives the larger share of portal venous blood flow from the colon, which is why amoebic trophozoites carried via the portal system most commonly form an abscess there.
Q3. How is this model different from the Cyst of Intestinal Protozoa of Man Model?
A. The Cyst of Intestinal Protozoa of Man Model focuses on diagnostic cyst identification under microscopy, while this model focuses on the clinical progression of invasive amoebiasis to extraintestinal, metastatic disease.
Q4. Is this model suitable for medical college teaching?
A. Yes, the model is designed to support pathology, parasitology and internal medicine curricula at medical and paramedical college level.
Q5. Can Jaincolab supply this along with other parasitology teaching models?
A. Yes, Jaincolab supplies this model alongside a full range of parasitology, pathology and microbiology teaching aids for biology laboratories across India and internationally.
