Scanning electron microscopic observation of cat lungs naturally infected with Aelurostrongylus abstrusus [Aelurostrongylus abstrusus i̇le doǧal enfekte kedi akciǧerlerinin taramali{dotless} elektron mikroskobu i̇le i̇ncelenmesi]

Aelurostrongylus abstrusus lives in terminal respiratory bronchioles and alveolar ducts of lung in cat. in this study,it was aimed that the lesions in lungs of cats naturally infected with a. abstrusus were observed using scanning electron microscope. white,miliar foci were observed on lung tissue examined macroscopically. alveolar cavities were disappeared around adult a. abstrusus body in the lung tissues examined with scanning electron microscope. alveoli were filled with first stage larvae of a. abstrusus. some cellular reactions were observed near to infected areas of lung tissue. worm nodule of a. abstrusus was not consisted in lungs of the cats. some alveolar cavities close to adult a. abstrusus filled with curled first stage larvae. these alveolar cavities were enlarged and alveolar septa were thickened.
