FIG. 1.

Ribotype patterns of a representative selection of Pseudomonas isolates after digestion with ClaI. Molecular weight markers ([DIG]-labelled lambda phage DNA fragments digested with HindIII [Boehringer]) are shown in lanes M. Lane 1, ATCC 27853 (group I); Lane 2, CIT-V2 (II); lane 3, CIT-V3 (II); lane 4, CIT-V4 (II); lane 5, CIT-V5 (II); lane 6, CIT-V6 (II); lane 7, CIT-V15 (III); lane 8, CIT-H1 (IV); lane 9, CIT-H2 (II); lane 10, CIT-H3 (VI); lane 11, CIT-H4 (II); lane 12, CIT-H5 (IV); lane 13, CIT-H6 (IV); lane 14, CIT-H7 (II); lane 15, CIT-H8 (II); lane 16, CIT-H9 (II); lane 17, CIT-H10 (V); lane 18, CIT-H11 (VI); lane 19, CIT-H12 (II); lane 20, CIT-H13 (VI); and lane 21, CIT-H14 (II). Numbers in parentheses denote ribotype groups.
