- Bacterial spot is an important bacterial disease of peppers.
- Two different bacteria, Xanthomonas campestris pv. vesicatoria (Xcv) and Xanthomonas vesicatoria (Xv) can incite this seed borne disease.
- mTMB (modified Tween Medium B) is a semi-selective medium for detection of Xcv and Xv on seeds of pepper and tomato.
- The colonies of Xcv and Xv on mTMB plates are yellow, slightly mucoid, mounded and round.
- Xcv utilizes Tween 80 and in 3-7 days a white crystalline halo usually forms around the yellow colony.
- Contaminated seed lots can be detected by dilution plating of the bacterial extract on CKTM, mKM or MXV.
- Suspected isolates are then transferred to YDC.
- Finally, the identity of the suspected isolates can be deter-mined by a pathogenicity test or PCR.
