Bacterial enteric infections in children: etiology, clinical manifestations and antimicrobial therapy

Area of Science:

• Microbiology
• Infectious Diseases
• Pediatrics

Background:

• Bacterial enteric infections pose a substantial global health burden, especially in children.
• Despite advances in understanding pathogenesis, diarrheal episodes and childhood mortality remain high worldwide.
• Antimicrobial therapy is crucial for specific infections but carries risks, such as hemolytic uremic syndrome with E. coli O157:H7.

Purpose of the Study:

• To review the impact of bacterial enteric infections on human health, particularly in pediatric populations.
• To discuss the role and risks of antimicrobial therapy in managing bacterial enteric infections.
• To highlight the potential of new preventive interventions, such as vaccines, driven by advancements in pathogen research.

Main Methods:

• Literature review of current knowledge on bacterial enteric infections.
• Analysis of the role of antimicrobial therapy in treating specific bacterial enteric pathogens.
• Exploration of emerging preventive strategies based on genomic and pathogenetic insights.

Main Results:

• Certain bacterial enteric infections necessitate specific antimicrobial treatments (e.g., shigellosis, cholera).
• Antimicrobial use may be beneficial in severe cases of Salmonella and Campylobacter infections but poses risks for E. coli O157:H7.
• Advancements in bacterial genome sequencing and pathogenesis understanding are paving the way for new interventions.

Conclusions:

• Bacterial enteric infections remain a critical global health challenge, particularly for children.
• Optimizing antimicrobial use and exploring novel preventive measures like vaccines are essential.
• Continued research into pathogenesis and genomics is key to combating these infections effectively.
