Aelurostrongylus abstrusus ile doğal enfekte kedi akciğerlerinin taramalı elektron mikroskobu ile incelenmesi

Aelurostrongylus abstrusus kedilerin akciğerinde terminal respiratorik bronşioller ile alveolar kanallarda yaşayan bir parazittir. Bu çalışma ile A. abstrusus’un kedi akciğerinde oluşturduğu lezyonların taramalı elektron mikroskobu kullanılarak incelenmesi amaçlanmıştır. A. abstrusus ile doğal enfekte üç kedinin nekropsisinde akciğerlerde miliyar tipte beyaz odaklar makroskobik olarak izlenmiştir. Bu bölgeler taramalı elektron mikroskobu ile incelendiğinde erişkin A. abstrusus’un etrafındaki akciğer dokusunda alveol boşluklarının gözden kaybolduğu, alveollerin parazite ait larvalar ile dolu olduğu gözlenmiştir. Bazı bölgelerde ise hücresel reaksiyonun şekillendiği dikkati çekmiştir. A. abstrusus’un kedi akciğerinde parazit nodülü oluşturmadığı, erişkin parazite yakın alveol boşluklarını kıvrılmış birinci dönem larvaların doldurduğu görülmüştür. A. abstrusus’un birinci dönem larvalarının bulunduğu alveol boşluklarının genişlediği ve alveol duvarının kalınlaştığı izlenmiştir.

Scanning electron microscopic observation of cat lungs naturally infected with Aelurostrongylus abstrusus

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.
