Betalactamase activity was studied in 142 non-tuberculosis mycobacterial strains. The distribution according to species was as follows: four M. avium, 14 M. chelanae, 10 M fortuitum, 59 M. gordonae, 55 M kansasii. The spectrum of hydrolysis of the betalactamases was screened using an acidimetric method and the characterization was performed by analytical isoelectric focusing. © 1995 Maney Publishing.
