Abstract:
According to diagnosis of the liquor cerebrospinalis in inflammatory diseases of the central nervous system there shall be demonstrated a method to support diagnosis and control of an efficient therapy of diffuse bacterial peritonitis. Mice were infected intraperitoneal with Escherichia coli suspension without complement. At intervals of 12 hours there was carried out a peritoneal lavage. The peritoneal lavage fluid was given into the sedimentary chamber according to Sayk. The sediment was coloured according to Pappenheim and differentiated under microscope. With help of the described method it is possible to take valuable informations about inflammation in peritoneal cavity by means of cellular composition of the peritoneal fluid in different times post infection. Of greatest importance is the number of polymorphonuclear cells in the exudate.
Insights
This study presents a method for diagnosing diffuse bacterial peritonitis by analyzing peritoneal lavage fluid in mice. The number of polymorphonuclear cells in the exudate is crucial for assessing inflammation and guiding therapy.
Area of Science:
- Microbiology
- Immunology
- Veterinary Medicine
Background:
- Accurate diagnosis and therapeutic monitoring of diffuse bacterial peritonitis are critical for patient outcomes.
- Current diagnostic methods may require refinement for timely and effective treatment.
Observation:
- Mice were infected with Escherichia coli and underwent serial peritoneal lavage.
- Peritoneal lavage fluid was analyzed using the Sayk chamber and Pappenheim staining.
- Cellular composition of the peritoneal fluid was examined at 12-hour intervals post-infection.
Findings:
- The method allows for valuable insights into peritoneal inflammation based on cellularity.
- Analysis of peritoneal fluid reveals dynamic changes in inflammatory cells over time.
- A high number of polymorphonuclear cells in the exudate indicates significant inflammation.
Implications:
- This technique can support the diagnosis of bacterial peritonitis.
- It offers a means to monitor the efficacy of anti-peritonitis therapies.
- The findings contribute to understanding host responses in bacterial peritonitis.
