Abstract
Pseudomonas tolaasii causing brown blotch disease was detected by PCR from water samples collected from the oyster mushroom cultivation farms to find the contamination level of the pathogen in water. Sixteen water samples (28.1%) contain less than 1,000 cfu, 31 samples (54.4%) contain 1,001-10,000 cfu, 6 samples (10.5%) contain 10,001-100,000 cfu, and 4 samples (7%) contain of bacteria per milliliter. P. tolaasii-specific DNA band was amplified in 3 samples (5.3%) by nested-PCR and in 20 samples (35.1%) by immunocapture (IC)-nested PCR respectively. These results suggest that IC-nested-PCR was much more sensitive than nested-PCR in detection of P. tolaasii and a quite few waters using for oyster mushroom cultivation were contaminated with P. tolaasii.
느타리 세균성갈색무늬병 병원균 P. tolaasii의 전염원을 파악하기 위하여 느타리 재배사에서 사용하고 있는 물로부터 PCR방법을 이용하여 병원세균을 검출한 결과, 주로 충북지방의 느타리 재배사에서 수집된 57개 물 시료 전체의 28.1%인 16개 물에는
