Book excerpt: Spontaneous Pathology of the Laboratory Non-human Primate serves as a "go to" resource for all pathologists working on primates in safety assessment studies. In addition, it helps diagnostic veterinary pathologists rule out spontaneous non-clinical disease pathologies when assigning cause of death to species in zoological collections. Primate species included are rhesus, cynomolgus macaques and marmosets. Multi-authored chapters are arranged by organ system, thus providing the necessary information for continued research.Pathologists often face a lack of suitable reference materials or historical data to determine if pathologic changes they are observing in monkeys are spontaneous or a consequence of other treatments or factors. - Contains color illustrations that depict the most common lesions to augment descriptions - Covers descriptions that are compliant with the International Harmonization of Nomenclature and Diagnostic Criteria (INHAND) guidelines set forth by the Society of Toxicologic Pathology (STP) - Provides pathologists with common terms that are compliant with the FDA's Standard for Exchange of Nonclinical Data (SEND) guidelines
