Necropsy Procedures and Evaluation of Macroscopic Lesions of Pigs Infected with African Swine Fever Virus

Pathology complements and provides a fundamental link to other disciplines for disease investigations supporting molecular biology, genetics, immunology, or virology as core basis of scientific research. Necropsies are an essential tool in veterinary pathology for disease investigation and should be conducted in a routine, systematic, and standard approach. An orderly necropsy procedure will allow the prosector (veterinary clinicians or veterinary pathologists) to determine macroscopically normal or altered structures and allow, through experience, to acquire dexterity, speed, and confidence in the technique. In conjunction with standardized macroscopic scoring protocols, necropsy is a powerful tool especially when using experimental animal models in research. Here, we describe a systematic necropsy protocol to be conducted on pigs infected with African swine fever virus (ASFV). The methodology described only requires rudimentary instruments, and it is not time-consuming. In addition to performing accurate tissue and organ assessment, the technique intends the prosector to carry out sampling of organs and tissues of interest in ASFV-infected pigs.  © 2022, The Author(s), under exclusive license to Springer Science+Business Media, LLC, part of Springer Nature.
