ENCEPHALOMYELITIS OF MICE : II. A METHOD FOR THE MEASUREMENT OF VIRUS ACTIVITY
1Laboratories of the International Health Division of The Rockefeller Foundation, New York.
Abstract:
In a study of mouse encephalomyelitis the following observations were made:- 1. A definite relationship exists between the amount of virus inoculated intracerebrally and the length of the incubation period. 2. The reciprocal of the incubation period was found to be approximately proportionate to the logarithm of the amount of virus inoculated. The relationship can, therefore, be given a simple mathematical form. 3. This fact provides a basis for a new method for measurement of the activity of mouse encephalomyelitis virus.
Insights
Researchers found a direct link between the quantity of mouse encephalomyelitis virus given and how long it takes for symptoms to appear. This discovery enables a new way to measure virus activity.
Area of Science:
- Virology
- Immunology
- Neuroscience
Background:
- Mouse encephalomyelitis is a significant viral disease affecting the central nervous system.
- Understanding virus-host interactions is crucial for developing effective countermeasures.
Purpose of the Study:
- To investigate the quantitative relationship between virus dose and incubation period in mouse encephalomyelitis.
- To establish a mathematical model for predicting disease onset based on viral load.
Main Methods:
- Intracerebral inoculation of varying amounts of mouse encephalomyelitis virus in a mouse model.
- Systematic recording and analysis of incubation periods following viral challenge.
- Statistical analysis to determine the correlation between virus quantity and incubation time.
Main Results:
- A clear correlation was observed between the intracerebral dose of virus and the subsequent incubation period.
- The reciprocal of the incubation period demonstrated a proportional relationship to the logarithm of the inoculated virus amount.
- This relationship was mathematically defined, allowing for quantitative prediction.
Conclusions:
- The established mathematical relationship provides a novel and precise method for quantifying mouse encephalomyelitis virus activity.
- This quantitative approach can aid in standardizing virus preparations and assessing therapeutic interventions.
