[Analysis of germ cultures in 57 cases of appendicular peritonitis and 16 postoperative septic complications]
Abstract:
Reliable bacteriological data were obtained from 53 and 16 out of 64 pediatric appendiceal peritonitis an 17 of their suppurative complications. Studies for aerobic and anaerobic flora ws performed in all. Each primitive peritoneal exudate contained a mixed flora with an average of 1.3 aerobic and 2.27 anaerobic species. E. coli and B. fragilis were almost constantly found among other enteric bacteria. Exudates from wound or intraabdominal complicative infections contained an average of 1.3 aerobic and 3 anaerobic species, and again E. coli and B. fragilis were constantly present. In eleven patients, there were exudates available from both the peritonitis and the complications, and the flora was coincident for, at least, one gram in all, and for two or more in eight. These facts enable us to point out the importance of anaerobes in peritoneal infections and their complications. At the same time, we recall that antibiotic treatment of peritonitis must be prescribed with this evidence in mind.
Insights
Pediatric appendiceal peritonitis and its complications frequently involve mixed aerobic and anaerobic bacteria, notably Escherichia coli and Bacteroides fragilis. Antibiotic strategies for peritonitis must consider the significant role of these anaerobic pathogens.
Area of Science:
- Microbiology
- Infectious Diseases
- Pediatric Surgery
Context:
- Appendiceal peritonitis is a serious intra-abdominal infection in children.
- Bacteriological analysis of peritoneal infections is crucial for effective treatment.
- Understanding the microbial flora in peritonitis and its complications guides therapeutic decisions.
Purpose:
- To characterize the aerobic and anaerobic bacterial flora in pediatric appendiceal peritonitis and associated suppurative complications.
- To identify consistently present bacterial species in peritoneal infections.
- To evaluate the microbial similarity between primary peritonitis and secondary infections.
Summary:
- Bacteriological data from 64 pediatric appendiceal peritonitis cases and 17 complications revealed mixed aerobic and anaerobic flora.
- Escherichia coli and Bacteroides fragilis were predominant in both peritonitis exudates and complication sites.
- Microbial analysis showed significant overlap in flora between primary peritonitis and subsequent infections, highlighting the importance of anaerobes.
Impact:
- Emphasizes the critical role of anaerobic bacteria, such as Bacteroides fragilis, in pediatric appendiceal peritonitis.
- Informs the selection of antibiotic regimens for peritonitis, advocating for broad-spectrum coverage that includes anaerobes.
- Provides essential microbiological insights for improving treatment outcomes in pediatric intra-abdominal infections.
