[Characteristics of peritoneal exudate microflora in children with appendicular peritonitis]

Area of Science:

• Pediatric Infectious Diseases
• Microbiology
• Clinical Bacteriology

Background:

• Peritonitis in children is a serious condition often requiring prompt diagnosis and treatment.
• Understanding the causative agents of pediatric peritonitis is crucial for effective management.
• Seasonal variations in infectious diseases are well-documented, but specific patterns for pediatric peritonitis require further investigation.

Purpose of the Study:

• To investigate the bacteriological profile of peritoneal exudate in children diagnosed with peritonitis.
• To identify potential seasonal trends in the prevalence of specific bacterial pathogens causing pediatric peritonitis.

Main Methods:

• A bacteriological analysis was performed on peritoneal exudate samples from 131 pediatric patients with peritonitis.
• Samples were collected and analyzed to identify the types and quantities of bacterial species present.

Main Results:

• The highest prevalence of pathogenic and conventionally pathogenic *Escherichia* and *Bacteroides* species was observed during the months of March, April, and September.
• During the summer months, peritonitis cases were frequently associated with pathogenic and conventionally pathogenic *Escherichia* species in combination with *Enterobacteriaceae*, *Staphylococci*, and other microorganisms.

Conclusions:

• Pediatric peritonitis exhibits distinct seasonal variations in its causative bacterial agents.
• The findings suggest that *Escherichia* and *Bacteroides* are key pathogens during spring and fall, while a broader spectrum of bacteria, including *Enterobacteriaceae* and *Staphylococci*, are implicated in summer peritonitis cases.
