[Biological properties of the causative agents of salmonellosis in young children]
Insights
Salmonella strains in feces and throat mucus were equally present in young children. Nasopharyngeal Salmonella strains showed higher virulence than fecal strains, indicating potential for hospital infections.
Area of Science:
- Microbiology
- Infectious Diseases
- Pediatrics
Background:
- Salmonellosis is a common infection in young children.
- Understanding Salmonella strain characteristics is crucial for infection control.
- Hospital-acquired infections are a significant concern in pediatric care.
Purpose of the Study:
- To investigate the biological properties of Salmonella strains isolated from young children.
- To compare the occurrence and virulence of Salmonella in different sample types.
- To identify Salmonella strains capable of causing hospital infections.
Main Methods:
- Isolation and biological property analysis of 161 Salmonella strains.
- Sampling from feces and faucial mucus of 121 young children.
- Comparative analysis of Salmonella strains from nasopharynx and feces.
Main Results:
- Salmonella occurrence was similar in feces and faucial mucus initially.
- Antibiotic-sensitive and group C Salmonella strains could cause hospital infections.
- Salmonella strains from the nasopharynx were statistically more virulent than fecal isolates.
Conclusions:
- Salmonella virulence varies by isolation site in infected children.
- Specific Salmonella strains pose a risk for hospital-acquired infections.
- Further research into targeted interventions for pediatric salmonellosis is warranted.
Abstract:
The study of the biological properties of 161 Salmonella strains isolated from the feces and faucial mucus of 121 young children revealed that at the initial period of salmonellosis the occurrence of Salmonella strains in these materials was the same. Salmonella strains sensitive to antibiotics, as well as group C salmonellae, were shown to be capable of causing hospital infections. Statistically significant results revealed that Salmonella strains isolated from the nasopharynx were more virulent than those isolated simultaneously from the feces of the same children.
