THE EXPERIMENTAL PRODUCTION OF PERIARTERITIS NODOSA IN THE RABBIT WITH A CONSIDERATION OF THE SPECIFIC CAUSAL
1Department of Pathology of Tulane University of Louisiana, New Orleans.
Abstract:
1. Periarteritis nodosa is a specific infectious disease which is transmissible to the rabbit. 2. The lesions induced in rabbits are identical with those occurring in man and consist of exudative and degenerative processes within the walls of the smaller arteries resulting in aneurysmal formations and thromboses. 3. The microorganism inducing the disease is capable of going through a Berkefeld N filter and is therefore to be classed with the group of so called filter passers.
Insights
Periarteritis nodosa, an infectious disease, was successfully transmitted to rabbits. The resulting arterial lesions in rabbits mimicked human cases, identifying the causative agent as a filterable microorganism.
Area of Science:
- Infectious Diseases
- Pathology
- Microbiology
Background:
- Periarteritis nodosa is a serious arterial inflammatory condition.
- Understanding its transmission and causative agents is crucial for diagnosis and treatment.
Purpose of the Study:
- To determine if Periarteritis nodosa is transmissible to rabbits.
- To characterize the pathological changes induced by the disease in rabbits.
- To investigate the nature of the infectious agent responsible for Periarteritis nodosa.
Main Methods:
- Experimental transmission of Periarteritis nodosa to rabbits.
- Histopathological examination of induced lesions in rabbit arteries.
- Filtration studies using Berkefeld N filters to characterize the infectious agent.
Main Results:
- Periarteritis nodosa was confirmed as transmissible to rabbits.
- Rabbits developed arterial lesions identical to human Periarteritis nodosa, including exudative and degenerative processes, aneurysms, and thromboses.
- The causative microorganism passed through a Berkefeld N filter, classifying it as a filterable agent.
Conclusions:
- Rabbits serve as a viable animal model for studying Periarteritis nodosa.
- The findings support the infectious etiology of Periarteritis nodosa.
- The causative agent of Periarteritis nodosa is a filter-passing microorganism.
