    Insights

    Cutaneous and pulmonary aspergillosis was diagnosed in rabbits, identified by characteristic Aspergillus species fungal elements in skin and lung tissues. Microscopic examination revealed distinct hyphal morphologies in different lesion types.

    Area of Science:

    • Veterinary Pathology
    • Mycology
    • Comparative Pathology

    Background:

    • Aspergillosis is a fungal infection caused by Aspergillus species.
    • It can affect various animal species, including rabbits.
    • Cutaneous and pulmonary forms present distinct clinical and pathological features.

    Purpose of the Study:

    • To diagnose and characterize cutaneous and pulmonary aspergillosis in rabbits.
    • To describe the histopathological findings associated with Aspergillus infection in rabbits.
    • To differentiate fungal morphologies in different affected tissues.

    Main Methods:

    • Histopathological examination of skin and lung tissues from affected rabbits.
    • Microscopic identification of fungal elements, including hyphae and mycelia.
    • Correlation of microscopic findings with clinical presentation.

    Main Results:

    • Cutaneous aspergillosis was characterized by the presence of dichotomous branching, septate hyphae typical of Aspergillus spp. within cystic hair follicles.
    • Pulmonary aspergillosis showed atypical, short, knobby mycelia with radiating projections in nodular lung lesions.
    • These findings confirmed the diagnosis of aspergillosis in both affected systems.

    Conclusions:

    • Aspergillus species can cause both cutaneous and pulmonary infections in rabbits.
    • Distinct microscopic morphologies of Aspergillus were observed in different tissues, aiding in diagnosis.
    • Histopathology is crucial for identifying and differentiating fungal infections in veterinary medicine.
