The susceptibility of 56 strains of Branhamella catarrhalis and ten Neisseria spp. to arsenate, silver, nickel, mercury, lead, cadmium, chromium, manganese, iron, cobalt and molybdenum was tested with an agar dilution technique. All but two strains of B. catarrhalis were resistant to multiple metal ions. There were not sufficient differences in susceptibility, however, to allow the development of a typing scheme based on resistograms. Heavy metal resistance in Branhamella was unrelated to beta‐lactamase production. Neisseria spp. were more susceptible to metal ions than B. catarrhalis and this may form the basis of a simple diagnostic test.
