What is the Difference Between Salmonella Typhi and Paratyphi?
🆚 Go to Comparative Table 🆚Salmonella Typhi and Salmonella Paratyphi are both bacteria that cause enteric fever, a systemic illness characterized by high fever, malaise, cough, rash, and enlarged spleen. However, there are some differences between the two:
- Severity: Paratyphoid infections tend to be less severe and less common than typhoid fever.
- Bacteria: Typhoid fever is caused by the bacteria Salmonella Typhi, while paratyphoid fever is caused by the bacteria Salmonella Paratyphi. These two bacteria are genetically distinct.
- Reservoirs: Humans are the only reservoir for Salmonella Typhi, while Salmonella Paratyphi also has animal reservoirs.
- Clinical Differences: Although paratyphoid fever is clinically similar to typhoid fever, the two organisms that cause the diseases exhibit different propensities to develop resistance to antibiotics.
- Diagnosis: Diagnostic tools available today struggle to discriminate between Salmonella Typhi and Salmonella Paratyphi A. However, recent research has developed a methodology that can determine if an individual is infected by Salmonella Typhi or Salmonella Paratyphi A.
Both bacteria can cause enteric fever, which is predominantly caused by S. Typhi, followed by S. Paratyphi A. Enteric fever is an important public health problem in many underdeveloped and developing countries, and both Salmonella species show a male preponderance in all age groups.
Comparative Table: Salmonella Typhi vs Paratyphi
Salmonella Typhi and Salmonella Paratyphi are two bacterial serotypes that cause typhoid fever and paratyphoid fever, respectively. Here is a table comparing the differences between the two:
Feature | Salmonella Typhi | Salmonella Paratyphi |
---|---|---|
Disease | Typhoid Fever | Paratyphoid Fever |
Symptoms | More severe | Less severe |
Invasiveness | More invasive | Less invasive |
Bacterial Type | Gram-negative rod-shaped bacteria | Gram-negative rod-shaped bacteria |
Flagella | Possesses flagella | Possesses flagella |
Disease Transmission | Fecal-oral route | Fecal-oral route |
Reservoir | Humans | Humans |
Both Salmonella Typhi and Paratyphi are highly adapted to humans and can be found in blood, fecal matter, and urine of infected individuals. They enter the human body through the fecal-oral route.
