Proteus and coliform meningoencephalitis in neonates
Abstract:
The characteristic necropsy and histological appearances are described of nine cases of Proteus meningoencephalitis in neonates. One case which was not due to Proteus has been included because of the close similarity of the gross appearances of the brain. Umbilical sepsis in half the cases indicated that this is a common portal of entry of these organisms. That epidemiological factors may be of importance in the aetiology was suggested by the distribution of cases.
Insights
Proteus meningoencephalitis in neonates is characterized by specific necropsy and histological findings. Umbilical sepsis is a common entry point for Proteus, suggesting epidemiological factors influence its occurrence.
Area of Science:
- Neonatal pathology
- Infectious diseases
- Neuropathology
Background:
- Meningoencephalitis in neonates is a severe condition.
- Proteus species are known pathogens.
- Understanding the pathology and epidemiology is crucial for neonates.
Purpose of the Study:
- To describe the pathological findings of Proteus meningoencephalitis in neonates.
- To identify common portals of entry for Proteus.
- To explore potential epidemiological factors.
Main Methods:
- Necropsy and histological examination of nine cases of neonatal meningoencephalitis.
- Inclusion of a non-Proteus case with similar gross brain findings for comparison.
- Analysis of case distribution and clinical history.
Main Results:
- Detailed description of characteristic necropsy and histological features of Proteus meningoencephalitis.
- Umbilical sepsis identified as a common portal of entry in 50% of cases.
- Observed distribution of cases suggests epidemiological influences.
Conclusions:
- Proteus meningoencephalitis in neonates has distinct pathological hallmarks.
- Umbilical sepsis is a significant route for Proteus infection in neonates.
- Epidemiological factors likely play a role in the aetiology of neonatal Proteus meningoencephalitis.
