Abstract
Leishmanial strains of mixed AB serotypes were tested by immunofluorescent techniques to determine if they comprise mixed populations of A and B organisms or whether each parasite carries both antigenic determinants. The strains used were classified as A1B2, A2B2, A3B2 and A4B2 by the behaviour of their excreted factor (EF) in double gel diffusion tests against standard A and B rabbit antisera. The results showed that all organisms of an AB strain were labelled with both fluorescent anti-A and anti-B sera and that such a population could be differentiated from an artificial mixture of A and B strains.
