Summary
Multiplex PCR significantly improved detection of viral, bacterial, and parasitic agents in pediatric acute diarrhea cases. Bacterial pathogens were most common, followed by viral and protozoal agents, highlighting the utility of molecular methods.
Area of Science:
- Microbiology
- Pediatric Infectious Diseases
- Molecular Diagnostics
Background:
- Acute diarrhea in children is a significant global health concern.
- Accurate identification of causative agents is crucial for effective treatment and control.
- Conventional diagnostic methods have limitations in sensitivity and scope.
Purpose of the Study:
- To comprehensively evaluate viral, bacterial, and parasitic agents in pediatric acute diarrhea.
- To compare the diagnostic yield of conventional methods with multiplex PCR.
- To determine the frequency distribution of various pathogens.
Main Methods:
- Stool samples from 101 pediatric patients were analyzed.
- Methods included macroscopic/microscopic examination, immunochromatographic tests, bacterial cultures, and multiplex PCR.
- Multiplex PCR targeted a broad range of viral, bacterial, and parasitic pathogens.
Main Results:
- Multiplex PCR identified bacterial pathogens in 83.2%, viral agents in 47.5%, and protozoal pathogens in 11.9%.
- Rotavirus was the most frequent viral agent; diarrheagenic *Escherichia coli* pathotypes were the most common bacterial findings.
- Multiplex PCR demonstrated superior pathogen detection compared to conventional methods.
Conclusions:
- Multiplex PCR significantly enhances the detection of pathogens causing acute diarrhea in children.
- Bacterial pathogens, particularly diarrheagenic *E. coli*, are highly prevalent.
- While molecular methods offer advantages, interpretation requires consideration of colonization versus infection, and conventional methods remain valuable.
