Abstract:
Serious Salmonella arizona infection may be acquired through the ingestion of rattlesnake meat used as a folk medicine remedy. We report a patient with metastatic carcinoma and a remote history of rattlesnake meat ingestion who developed recurrent S. arizona bacteremia and reactivation of tuberculosis after receiving corticosteroid and radiation therapy. Physicians should be aware of the potential for rattlesnake-associated S. arizona infection to occur as either the presenting manifestation or as a complication in immunosuppressed patients who may take folk remedies, especially Hispanics who live along the United States-Mexico border.
Insights
Serious Salmonella arizona infection can result from consuming rattlesnake meat as folk medicine. This can lead to severe illness, especially in immunocompromised individuals, highlighting a risk for specific populations.
Area of Science:
- Infectious Diseases
- Microbiology
- Public Health
Background:
- Salmonella arizona (S. arizona) infections are rare but can be serious.
- Folk medicine practices, including the use of rattlesnake meat, are prevalent in some communities.
- Immunosuppression can increase susceptibility to opportunistic infections.
Observation:
- A patient with metastatic carcinoma and a history of consuming rattlesnake meat developed recurrent S. arizona bacteremia.
- The patient also experienced reactivation of tuberculosis.
- These events occurred after corticosteroid and radiation therapy, indicating iatrogenic immunosuppression.
Findings:
- Rattlesnake meat ingestion is a potential source of S. arizona infection.
- Immunosuppressed patients are at risk for S. arizona bacteremia and reactivation of latent infections like tuberculosis.
- This risk is particularly relevant for Hispanic populations along the US-Mexico border who may use folk remedies.
Implications:
- Physicians must consider S. arizona infection in patients with relevant exposure history, especially if they are immunocompromised.
- Awareness of folk medicine practices is crucial for diagnosing and managing infections.
- Public health initiatives may be needed to educate at-risk communities about the dangers of consuming contaminated folk remedies.
