Notice: Cessation of distribution of Mycobacterium timonense JCM 17325^T / Start of distribution of JCM 30726^T for authentic Mycobacterium timonense

September 28, 2015

Mycobacterium timonense was proposed as a new species within the Mycobacterium avium complex in 2009, and was deposited in CCUG (Sweden) and CIP (France). Our stock culture of Mycobacterium timonense JCM 17325^T was accessioned from CCUG and had been distributed since 2010. Recently we were informed by a user that the 16S rRNA gene sequence of JCM 17325^T was identical with that of Mycobacterium avium and we confirmed it. For further investigation, we obtained Mycobacterium timonense from CIP and confirmed the authenticity by sequencing of the 16S rRNA gene. This strain is available as JCM 30726^T. Distribution of JCM 17325^T has been stopped.

To ensure authenticity of Mycobacterium strains at JCM, we will execute more careful examination when we receive a strain of this genus for deposit. In cases that the sequence of the 16S rRNA gene is not 100% identical with that of its published data, we will examine a gene used for effective discrimination in the literature for confirmation of the authenticity of the strain. We appreciate your support and understanding of our activities.

We informed users of JCM 17325^T of this matter in detail with our sincere apology, asked for stopping its use and provided information on the replaced culture.

If you have any question and concern on this matter, please feel free to contact us (inquiry.jcmriken.jp).
