A total of 309 @entity1534 isolates from 18 different countries were analyzed with a previously developed lectin typing system. The system was developed by using a proteolytic pretreatment to enhance the @entity1735 fraction of the sample. Four lectins from Ulex europaeus, Lotus tetragonolobus, Erythrina cristigali, and Triticum @entity6248 were used to type the strains. The lectins were chosen for their specificities for @entity3363 commonly encountered in the lipopolysaccharide of @entity1534 . The isolates were received from their parent institutions as pellets of biomass and were typed at one of three centers (in Ireland, Sweden, and Estonia). All 16 possible lectin reaction patterns were observed in the study, with the isolates with the predominant pattern exhibiting reactions with all the lectins in the panel. For European @entity1 suffering from @entity3621 , an association was noted between lectin reaction pattern MH4 and @entity4726 ; isolates with lectin reaction pattern MH4 were isolated from @entity1 with @entity4726 , whereas isolates with this pattern were not isolated from @entity1 with chronic @entity3621 (P = 0.0006). In addition, statistically significant relationships were noted between the lectin reaction pattern and the associated pathology of isolates from the Swedish population. Isolates with patterns MH13 and MH16, which had low lectin reactivities, correlated with @entity66 (P = 0.0025 and P = 0.0002, respectively), and all four isolates from @entity420 @entity1 were characterized as possessing reaction pattern MH16. In contrast, isolates with lectin reaction patterns MH1 and MH10, which had high lectin reactivities, were associated with @entity1066 (P = 0.046 and P = 0.0022, respectively).
