Life Cycle of Leishmania Donovani Model
Product Code : JC-BE-6251
The Life Cycle of Leishmania Donovani Model from Jaincolab is an educational chart illustrating the life cycle of Leishmania donovani, the protozoan parasite responsible for visceral leishmaniasis (kala-azar), a serious systemic disease that remains endemic in parts of India. The model traces the parasite through its two morphological forms, promastigote in the sandfly vector and amastigote in the human host, and its characteristic invasion of the reticuloendothelial system.
As a trusted biology lab equipment supplier in India, Jaincolab designs this model to give students of parasitology and clinical medicine a focused, organism-specific understanding of kala-azar transmission and pathology, complementing the broader comparative overview provided by Jaincolab's Blood and Tissue Protozoal Infection Model, supporting classroom teaching and laboratory demonstration.
What the Concept States
| Parameter | Details |
|---|---|
| Causative Organism | Leishmania donovani (Kinetoplastida) |
| Vector | Female sandfly (Phlebotomus species in the Old World, including India) |
| Promastigote Stage | Flagellated, extracellular form that develops and multiplies in the sandfly gut before being transmitted during a blood meal |
| Human Infection Route | Introduced into the skin during a sandfly bite, where promastigotes are phagocytosed by macrophages |
| Amastigote Stage | Non-flagellated, intracellular form that multiplies within macrophages of the reticuloendothelial system |
| Primary Organs Affected | Spleen, liver and bone marrow, leading to marked organomegaly, anemia and immune dysfunction characteristic of visceral leishmaniasis |
| Diagnostic Approach Illustrated | Demonstration of amastigotes (Leishman-Donovan bodies) in splenic, bone marrow or lymph node aspirate smears, alongside serological testing |
Key Features
- Clearly labelled illustration of the promastigote-amastigote alternation between sandfly vector and human host
- Highlights the reticuloendothelial organ involvement characteristic of visceral leishmaniasis
- Connects vector biology to the diagnostic identification of Leishman-Donovan bodies
- Durable, classroom- and laboratory-ready construction suitable for repeated use in practical sessions
- Supports parasitology, microbiology and tropical/community medicine curricula
- Complements the Blood and Tissue Protozoal Infection Model with a focused, single-organism deep dive
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 Life Cycle of Leishmania Donovani Model is designed to accompany the Blood and Tissue Protozoal Infection Model, giving institutions a progression from the broader comparative overview to detailed, organism-specific life-cycle teaching, particularly relevant given kala-azar's continued public health significance in parts of India. Every model is checked for labelling accuracy before dispatch, helping instructors present parasitology with confidence.

Frequently Asked Questions
Q1. What does the Life Cycle of Leishmania Donovani Model illustrate?
A. It illustrates the complete life cycle of Leishmania donovani, including its promastigote form in the sandfly vector, its intracellular amastigote form in human macrophages, and its characteristic invasion of the spleen, liver and bone marrow.
Q2. What disease does Leishmania donovani cause?
A. It causes visceral leishmaniasis, commonly known as kala-azar, a serious systemic disease with organomegaly, anemia and immune dysfunction, which remains a public health concern in parts of India.
Q3. How is visceral leishmaniasis diagnosed according to this model?
A. Diagnosis is illustrated through the demonstration of amastigotes, also called Leishman-Donovan bodies, in splenic, bone marrow or lymph node aspirate smears, supported by serological testing.
Q4. How is this model different from the Blood and Tissue Protozoal Infection Model?
A. The Blood and Tissue Protozoal Infection Model gives a broad comparative overview of malaria, trypanosomiasis, leishmaniasis and toxoplasmosis together, while this model focuses in detail on the specific life cycle and pathology of Leishmania donovani alone.
Q5. Can Jaincolab supply this along with other parasitology teaching models?
A. Yes, Jaincolab supplies this model alongside a full range of parasitology, microbiology and tropical medicine teaching aids for biology laboratories across India and internationally.
