초록

병원성 Mycoplasma hyopneumoniae strain 91-3, 비병원성 M. hyopneumoniae 그리고 M. flocculare를 돼지의 기관지섬모상피에 투여시 세포내 $Ca^{2+}$ 농도 [$Ca^{2+]}$$_{i}$ 의 변화를 본 연구에서 조사하였다. M. hyopneumoniae strain 91-3 (300-$\mu\textrm{g}$ml)를 투여시 기관지 섬모상피내의 $Ca^{2+}$가 투여전과 비교시 투여 후 250$\pm$19 nM (net increase)증가하였다 (10회 반복 47 cells). 이와는 대조적으로 비병원성 M. hyopneumoniae (300 $\mu\textrm{g}$ml) (6회 반복 18 cells)와 M. flocculare (300 $\mu\textrm{g}$ml) (8회 반복 24 cells)는 세포내 $Ca^{2+}$의 농도를 증가시키지 못하였다. 위의 결과로 병원성 M. hyopneumoniae 91-3 균주는 비병원성 mycoplasma와는 다르게 돼지의 섬모상피에서 [$Ca^{2+}$]$_{i}$ 을 유도하였으며 이러한 특성은 mycoplasma 감염증 치료에 중요한 단서를 제공할 뿐만 아니라 새로운 치료법의 개발에 유용한 스크리닝 기술에 응용될 것으로 기대된다.
