A rapid and reliable test for demonstrating porphyrin synthesis in Haemophilus strains is described. The method is performed with cell suspensions, and tests the ability of the bacteria to use δ-aminolaevulinic acid in the biosynthesis of porphobilinogen and porphyrins. The method permits detection of some of the enzyme activities involved in the haemin biosynthetic pathway, and offers as such a more reproducible alternative to the traditional tests for haemin requirement in Haemophilus strains… CONTINUE READING
