萎蔫短小杆菌 (Cff) - DAS ELISA 检测试剂盒

Genus: Curtobacterium

Symptoms: The disease is characterized by the wilting of leaves, or parts of

them, initially during the warmest hours of the day, followed by a recovery as

the temperature drops in the evening. Wilting becomes permanent during

the following days as a result of bacterial plugging of the vessels when

the water supply is cut off; the leaves turn brown and then drop.

Main host plants and diseases: Curtobacterium flaccumfaciens pv

flaccumfaciens is the causal agent of the bacterial wilt disease of

Phaseolus spp. and is a systemic bacterium.

Transmission: Cff can be transmitted to soybean seeds of susceptible

cultivars at low rates.

Sensitivity: Sensitivity of the ELISA is relatively high. The bacteria can be

consistently detected in infected plant tissues diluted at 1:90 - 270.

Reactivity: Reaction of the ELISA is moderately strong. Optical Density at

405_nm is in a range of 0.650 - 1.700 depending on the bacterial titer in the

samples tested.

Specificity: This test system has no cross reaction with healthy plant tissues

tested. Background is low on the negative control wells.
