Abstract

Biochemical data as enzyme profiles which were obtained by cellulose acetate electrophoresis (CAE) are reported on 44 isolates. These enzyme profiles contain data from 25 enzyme systems. Calculations from the CAE data on average polymorphism indicated that species/types or groups can be expected to be about 25% polymorphic, which suggests that isolate pairs which have profiles about 75% or more identical should be considered samples from the same species/type, and isolates that are significantly less than 75% identical are therefore samples from different species/types. There were five major groupings of isolates according to enzyme profiles, which were for the most part consistent with groupings of the genus based on other criteria: and profiles. Within these groups there were natural subgroups of isolates among which there was 75% or more allozyme or allomorph (genetic) identity. The profile group had two subgroups: and or , and the profile group had three subgroups: and . There was an indication that an isolate might be different from the other isolates, and that the isolates could be samples from more than one group. The data reported here are consistent with previously reported CAE data, but suggest that isozyme analysis of isolates leading to identification should be based on data from many enzyme systems rather than just a few.
