Identification of the causal agents of
BBLS. All 10 citrus BBLS isolates were
Gram-negative. Isolates 6269 and 6369
were identified as B. andropogonis using
carbon utilization profiles. Isolates 6268,
6269, 6367, 6368, 6369, and 6370 were
identified as B. andropogonis using FAME
analysis, and their index values varied
from 0.692 to 0.934. The dendrogram
produced based on fatty acid composition
showed that these six isolates formed a
cluster with B. andropogonis, separate
from B. glumae and B. gladioli. They appear
to be the same species (Fig. 4).
