Note: According to Rules 27(3) and 30 [1], this new species is not validly published because the effective publication only documents deposit of the type strain in a single recognized culture collection. However deposit in at least one other recognized culture collections in a different country is documented. In a Request for an Opinion, Euzéby and Tindall provide a solution whereby this name may be considered to be validly published [2].

FL56 is a canine Helicobacter strain [see HÄNNINEN (M.L.), KARENLAMPI (R.I.), KOORT (J.M.), MIKKONEN (T.) and BJORKROTH (K.J.): Extension of the species Helicobacter bilis to include the reference strains of Helicobacter sp. flexispira taxa 2, 3 and 8 and Finnish canine and feline flexispira strains.

1 The strain ATCC 35683, designated as the type strain of ¤ Campylobacter cinaedi by Totten et al. 1985 [1] and as the type strain of Helicobacter cinaedi by Vandamme et al. 1991 [2], is not the type strain of Helicobacter cinaedi. It is a strain of ¤ Helicobacter fennelliae (¤ Campylobacter fennelliae) [3, 4, 5, 6]. The origin of the strain ATCC 35683remains unknown. According to P. Vandamme [6] and to S.L.W. On [7], if the origin of this strain cannot be confirmed, it should be withdrawn from distribution.

Note: Helicobacter cynogastricus sp. nov. JKM4^T = LMG 23188^T has been submitted to the CCUG and NCTC culture collections but, due to the extremely fastidious nature of Helicobacter species, the strain has not been able to be revived or stored after lyophilisation. Consequently, a committee consisting of the Chairman of the ICSP, the Chairman of the JC of the ICSP and the Editor of the International Journal of Systematic and Evolutionary Microbiology 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.

Note: Genetic data indicate that the type strain (and the only available strain) of Helicobacter nemestrinae is really a strain of Helicobacter pylori and that Helicobacter nemestrinae Brondson et al. 1991 is a later heterotypic synonym of ¤ Helicobacter pylori (Marshall et al. 1985) Goodwin et al. 1989 [1]. Although, DNA-DNA hybridization data are required to determine the taxonomic status of Helicobacter nemestrinae, unequivocally, the members of the Subcommittee on the taxonomy of Campylobacter and related bacteria felt that the current evidence strongly indicated that the Helicobacter nemestrinae type strain was, in fact, an Helicobacter pylori strain [2].

Notes:
1 Helicobacter typhlonius Franklin et al. 2002 was previously known as "Helicobacter typhlonicus" Franklin et al. 1999.
Franklin et al. 2001 [1] wrote: "... Franklin et al. [2] described a disease syndrome characterized by proliferative typhlocolitis in C.B-17 scid/scid mice naturally and experimentally infected with a novel species of Helicobacter that was provisionally named "Helicobacter typhlonicus". ... In this report, we propose to use the more appropriate neo-Latin adjective "typhlonius" and formally name this novel helicobacter Helicobacter typhlonius".

2 According to Rules 27(3) and 30, this name is not validly published, because the original publication makes reference to the deposit of the type strain in a single recognized culture collection. However, according to the Judicial Opinion 81, Helicobacter typhlonius Franklin et al. 2002 is considered to be validly published, since deposit in a second culture collection in a different country has been documented.
