경북북부 지역 화훼농가에서 재배되는 시클라멘 (Cyclamen europaeum)에서 무름병이 발생되었다. 별든 시클라멘의 구근(球根)이 흑갈색으로 물러 썩었으며, 지상부가 시들어 죽었다. 병든 식물로부터 분리된 병원세균의 형태ㆍ생리적 특성과 지방산 조성을 분석한 결과, Pectobacterium carotovorum subsp. carotovorum (Erwinia carotovora subsp. carotovora)으로 동정되었다. 이 세균에 의한 시클라멘의 병은 아직 국내에서 보고된 바가 없기에, 이 병을 시클라멘의 세균성무름병 (bacterial soft rot)으로 부를 것을 제안한다.

Soft rot occurred on the cyclamen plants (Cyclamen europaeum) cultivated in the northern Kyungbuk. The mushy and black symptom appeared on the cyclamen bulbs. The diseased plants wilted and resulted in death of the aboveground plants. The causal organism was isolated from the lesion and was identified as Pectobacterium carotovorum subsp. carotovorum (Erwinia carotovora subsp. carotovora) based on the morphological and physiological characteristics and on fatty acid composition analysis by MIDI sherlock system. P. carotovorum subsp. carotovorum is the first described bacterium which causes bacterial soft rot of cyclamen in Korea.
