The reactions are shown as follows: *synergistic CAMP-like reaction with indicator strains; **results mostly obtained from Ülbegi-Mohyla et al., 2010 [6]; +: positive reaction; (+): weak positive reaction; −: negative reaction. 1Api-Coryne test system (Biomerieux, Nürtingen, Germany); 2tablets containing substrates (Rosco Diagnostica A/S, Taastrup, Denmark); 34-methylumbelliferyl conjugated substrates (Sigma, Steinheim, Germany).
