Rickettsia asiatica Fujita et al. 2006, sp. nov.
Type strain: (see also StrainInfo.net) strain IO-1 = ATCC VR-1593 = CSUR R2.
Sequence accession no. (16S rRNA gene) for the type strain: AF394906.
Etymology: L. fem. adj. asiatica, Asian.
Reference: FUJITA (H.), FOURNIER (P.E.), TAKADA (N.), SAITO (T.) and RAOULT (D.): Rickettsia asiatica sp. nov., isolated in Japan. Int. J. Syst. Evol. Microbiol., 2006, 56, 2365-2368.
Original article in IJSEM Online

Note:
At the time of publication, the type strain IO-1 was deposited in only one culture collection with the accession number CSUR R2. However, Rickettsia asiatica Fujita et al. 2006 was validly published because a committee consisting of the Chairman of the ICSP, the Chairman of the JC of the ICSP and the Editor of the IJSEM has granted an exception in this instance to Rule 27(3) of the Bacteriological Code governing the deposit of type material in two different collections in two different countries. This exception was granted in anticipation of the published minutes of the meetings of the International Committee on Systematics of Prokaryotes (ICSP) and its Judicial Commission (JC) in San Francisco in 2005.
In March 2008, the authors have obtained the ATCC certificate for the type strain of this species which meets all requirements of Rule 27(3).

2 In the Kilian's opinion [1] the change of the well-established name Rickettsia canada may be a source of confusion. So, with reference to the first Principle of the Bacteriological Code (1990 Revision), Kilian requested that the original name Rickettsia canada be conserved [2]. The Judicial Commission denied this request, and no Opinion will be issued upon this request [3].

Notes:
1 Rickettsia felis Bouyer et al. 2001 was previously known as the ELB agent [for the EL Laboratory (Soquel, California, U.S.A.)] or as "Rickettsia felis" Higgins et al. 1996.
2 According to Rules 27(3) and 30, Rickettsia felis Bouyer et al. 2001 is not validly published because, at the time of publication, the type strain was not deposited in two publicly accessible service collections in different countries. According to the Judicial Opinion 81, authors or this name, or other scientists who wish to have this name validly published, should submit evidence of the deposit of the type strain in additional collections to the List Editor (either directly or via the IJSEM Editorial Office) before the next meeting of the Judicial Commission in Sapporo, Japan, in 2011. After that time, the name will be ruled not to have been validly published. If, after that deadline, the authors or other scientists wish to have this name validly published, this may be done by confirming that the name is in accordance with the requirements of the Code and either by requesting valid publication via the Validation Lists or by inclusion of the proposal in an original article in the IJSEM. The details of valid publication will then make reference to those publications. If authors or other scientists feel that an exception should be granted to Rule 30, requiring deposit of the type in two different collections in two different countries, they should contact the Editorial Office of the IJSEM.

3 The type strain designation has been misidentified as Brein-1 or Brein 1 in some publications, which could be due to the font in which it was written. This strain was isolated from a patient in Warsaw, Poland  during the epidemic of 1919-1921, was obtained by Dr. Breinl in 1926 from the Institute of Hygiene, Warsaw, Poland, transferred to Dr. Maxcy in 1928, and was donated to the ATCC collection in 1962 by Dr. E.

Rickettsia tamurae Fournier et al. 2006, sp. nov.

Sequence accession no. (16S rRNA gene) for the type strain: AY049981.
Etymology: N.L. gen. masc. n. tamurae, of Tamura, named in honour of the Japanese rickettsiologist Dr Akira Tamura, who contributed to our knowledge of rickettsiae and rickettsioses in Japan.

Original article in IJSEM Online

Note:
At the time of publication, the type strain AT-1 was deposited in only one culture collection with the accession number CSUR R1. However, Rickettsia tamurae Fournier et al. 2006 was validly published because a committee consisting of the Chairman of the ICSP, the Chairman of the JC of the ICSP and the Editor of the IJSEM has granted an exception in this instance to Rule 27(3) of the Bacteriological Code governing the deposit of type material in two different collections in two different countries. This exception was granted in anticipation of the published minutes of the meetings of the International Committee on Systematics of Prokaryotes (ICSP) and its Judicial Commission (JC) in San Francisco in 2005.
In March 2008, the authors have obtained the ATCC certificate for the type strain of this species which meets all requirements of Rule 27(3).
