    Summary

    A rare noma-like lesion was identified in macaques, sharing key clinical and systemic features with human noma. This discovery offers a primate model for studying noma

    Area of Science:

    • Veterinary Pathology
    • Primatology
    • Infectious Diseases

    Background:

    • Noma, a devastating orofacial gangrenous disease, primarily affects malnourished children.
    • The exact etiology and pathophysiology of noma remain incompletely understood.
    • Previous studies have lacked a suitable animal model for comprehensive research.

    Observation:

    • A lesion consistent with noma was documented in a Macaca cyclopis (Formosan rock macaque).
    • The macaque lesion exhibited gangrenous characteristics, necrotizing ulcerative gingivitis, and extensive orofacial tissue/bone destruction.
    • Systemic signs included host debilitation, leukocytosis, and suppressed cellular immunity.

    Findings:

    • Microbiologic analysis identified organisms typically associated with necrotizing ulcerative gingivitis.
    • The observed clinical and systemic features closely mirror those of human noma.
    • This represents a significant finding in nonhuman primate pathology.

    Implications:

    • The Formosan rock macaque may serve as a valuable nonhuman primate model for noma research.
    • Studying this condition in macaques could elucidate noma's etiology, pathophysiology, and host-pathogen interactions.
    • Findings may accelerate the development of novel therapeutic strategies for human noma patients.
