Hardy Diagnostics has just released Arcanobacterium Selective Agar (also known as Berger's Agar, Cat no. A134), a novel medium for the isolation of Arcanobacterium haemolyticum, especially from respiratory specimens.
Selective agents have been added to the medium to inhibit Streptococcus pyogenes and normal oral flora without affecting the growth of Arcanobacterium haemolyticum. Also released by Hardy Diagnostics is a bi-plate, consisting of Group A Beta Strep Selective Agar and Arcanobacterium Selective Agar (Cat. no. J134) so that throat cultures can be effectively screened for both Group A Strep and Arcanobacterium simultaneously.
Daniel Berger a Research and Development Microbiologist at Hardy Diagnostics has prepared an article discussing the significance and potential under reporting of A.haemolyticum, click here to download the full text pdf from Hardy Diagnostics website.
