Insights
Salmonella apapa, a reptile-associated bacteria, can infect humans, even newborns. This case highlights the risk of Salmonella apapa infection in infants from contact with infected pets like bearded dragons.
Area of Science:
- Microbiology
- Zoonotic Diseases
- Infectious Diseases
Context:
- Salmonella apapa is a rare bacterial pathogen primarily transmitted by reptiles.
- Human infections are infrequently reported, but transmission via animal feces or direct contact is possible.
- Infants are particularly vulnerable due to immature immune systems and close contact with household environments.
Purpose:
- To report a case of Salmonella apapa sepsis in a neonate.
- To identify the source of infection in the infant.
- To raise awareness about the zoonotic potential of Salmonella apapa.
Summary:
- An 18-day-old infant developed sepsis caused by Salmonella apapa.
- The same bacterial strain was isolated from the feces of a family pet bearded dragon.
- This finding confirms the reptile-to-human transmission route in this case.
Impact:
- This case underscores the importance of hygiene practices when keeping reptiles as pets, especially in households with infants.
- It highlights the need for increased awareness among healthcare providers regarding rare Salmonella serovars in neonates.
- Further research may be warranted to understand the prevalence and pathogenicity of Salmonella apapa in both animal reservoirs and human populations.
Abstract:
Salmonella apapa is transmitted by reptiles, e.g., bearded dragons. To date only few cases of S. apapa-related human infections have been reported. Because the bacteria are transmitted through the feces of animals or direct contact with low infection doses, infection in early infancy is possible. We report an 18-day-old newborn with sepsis caused by Salmonella apapa. Salmonella apapa was isolated from the feces of a bearded dragon living along with the family.
