Escherichia and Salmonella Species Model
Product Code : JC-BE-6188
The Escherichia and Salmonella Species Model from Jaincolab is a three-dimensional teaching model that compares Escherichia coli and Salmonella species within the Enterobacteriaceae family.
It is used in microbiology courses to explain how biochemical tests differentiate these closely related genera and to describe the diseases each can cause.
What the Concept States
| Parameter | Details |
|---|---|
| Escherichia coli | A normal gut commensal; certain pathogenic strains such as ETEC and EHEC O157:H7 cause diarrhea and hemolytic uremic syndrome |
| Salmonella Species | Includes Salmonella Typhi, causing typhoid fever, and non-typhoidal serovars causing gastroenteritis |
| Lactose Fermentation | E. coli ferments lactose (pink colonies on MacConkey agar); most Salmonella species do not |
| Hydrogen Sulfide Production | Many Salmonella species produce H2S, seen as blackening on TSI or SIM medium, unlike E. coli |
| Transmission | Both spread mainly via the fecal-oral route through contaminated food or water |
Key Features
- Compares Escherichia coli and Salmonella species structure and biochemistry
- Shows key differentiating tests such as lactose fermentation and H2S production
- Explains the disease spectrum of pathogenic E. coli and Salmonella strains
- Durable, exam-oriented construction for repeated classroom use
- Compact benchtop format suitable for laboratories and lecture halls

Frequently Asked Questions
Q1. What does the Escherichia and Salmonella Species Model demonstrate?
A. It demonstrates the comparative biology and disease associations of Escherichia coli and Salmonella species.
Q2. What diseases does pathogenic E. coli cause?
A. Pathogenic strains such as ETEC and EHEC O157:H7 cause diarrheal disease and, in severe cases, hemolytic uremic syndrome.
Q3. What disease does Salmonella Typhi cause?
A. Salmonella Typhi causes typhoid fever, a systemic infection transmitted through contaminated food or water.
Q4. How are E. coli and Salmonella differentiated in the laboratory?
A. Lactose fermentation and hydrogen sulfide production on differential media such as MacConkey and TSI agar help differentiate the two genera.
Q5. Who uses this model?
A. Microbiology and medical students and faculty use it to study Escherichia and Salmonella species.
