a
Plants were sampled at one location (the leaf petiole on the apical portion of the plant) for X. fastidiosa culturing at 11 months after inoculation.
b
See Table 1 for additional information on isolates.
c
Number of infected plants/number of inoculated plants. In parenthesis is the mean number of CFU per gram of plant tissue (log10 value ± standard error).
d
Number of plants expressing symptoms/number of inoculated plants.
e
Typical CLS symptoms were not recorded for coffee plants within 11 months after inoculation.
