International Committee on Systematics of Prokaryotes Subcommittee on the taxonomy of the Pasteurellaceae

Minute 4. Last subcommittee meeting. H. Christensen explained that the last meeting of the Subcommittee on the Pasteurellaceae had been held on 30 July 2002 at the IUMS conference in Paris but minutes had not been prepared from that meeting. A main decision from the meeting had been to circulate important matters of the subcommittee to its members by email. In addition, new prospective members were suggested (see below).

Minute 3. Approval of agenda.An agenda was circulated electronically.No additional points to the agenda were made.
Tom Inzana gave an update on the work proposed at the last meeting on reclassification of [Haemophilus] ducreyi.Since it is very difficult to mail live bacterial strains any more, and since infection due to [H.] ducreyi in the USA is very rare, he still does not have any strains.Therefore, owing to the lack of field strains this initiative had to be stopped.However, he proposed changing efforts to take up reclassifying [Haemophilus] parasuis.
At the last meeting, Paul Langford initiated genome sequencing of Actinobacillus pleuropneumoniae serotype 8 reference strains from several laboratories in order to solve confusion on various strains obviously circulating.This is still ongoing but will soon be finished.Minute 7. Publishing in IJSEM.Members expressed their concern that there are no general and transparent guidelines for the evaluation of manuscripts submitted to IJSEM.The review is often subject to arbitrariness and forcing of specific and commercial methods.The 'minimal standards' published for the family Pasteurellaceae have not improved the situation.Some reviewers and editors will always find yet another method necessary of being included, while for other taxa single strain descriptions, not taking into account biodiversity, are accepted.Of course this is minimizing variable characteristics, simplifying descriptions, but generating massive future problems.Members agreed to write a letter of concern to the editorial board raising these points.phylogeny as well as in the framework as a tool for description of new taxa.Paul Planet presented an update on whole genome phylogeny of the family Pasteurellaceae at the conference in Prato.He proposed a plan for generating and analysing whole genome sequences of more members of the family Pasteurellaceae.There was agreement that as many species as possible, from as many places and temporal spaces as possible should be included in such an approach.In all cases type strains should be incorporated.Genomic DNA could be sent to Paul Planet, wrapped in aluminium foil to prevent nicking from X-ray scans during transport.In a first step a selection of strains should be done, then sending of strains should be coordinated and finally financing of such a collaborative project should be secured.A letter of support from members or the subcommittee to Paul Planet would be needed.In this paper, Peter Vandamme, significantly involved in defining the polyphasic taxonomy approach, recognizes exactly this as 'one of the main reasons ... why we have a ridiculously short list of ... bacterial species named today'.As a consequence, he advocates for 'a full genome sequence and a minimal description of phenotypic characteristics' as being appropriate for species description.The chair and secretary agreed that whole genome sequences should not become compulsory for description of new taxa at the moment, in particular not as yet another method and dataset added to the polyphasic approach.However, the proposal of Peter Vandamme formulated in his paper should be discussed in more detail within the subcommittee and a consensus should be found to overcome outdated approaches and to eventually advance taxonomy of the family Pasteurellaceae.

Minute 6 .
Use of MALDI-TOF MS for taxonomy.Matrix assisted laser desorption/ionization time-of-flight (MALDI-TOF) MS has proved useful for identification and differentiation of members of the family Pasteurellaceae [Alispahic et al., Int J Med Microbiol 301 (2011), 513-522; Kuhnert et al., J Microbiol Methods 89 (2012), 1-7].It has also been applied in the description of the species H. sputorum by Nørskov-Lauritsen et al. [Int J Med Microbiol 302 (2012), 78-83] and F. canicola by Korczak et al. [Antonie van Leeuwenhoek 105 (2014), 731-741].The members agreed that this technique should be included whenever possible and wherever useful for the description and (re)classification of taxa.
Minute 8. Varia.The need for whole genome sequences was discussed both in the context of a comprehensive IP: 54.70.40.11On: Thu, 03 Jan 2019 09:31:43 Minute 9. Adjournment.The open meeting was adjourned at 15 : 05 on 15 May 2014.Session 2 -Closed meeting Minute 10.Call to order.The closed meeting planned to be held at the IUMS meeting in Montreal 2014 was cancelled beforehand on the occasion of the open meeting in Italy since only two members of the subcommittee were supposed to attend IUMS 2014.Issues for the closed meeting were therefore communicated by email.Minute 11.Current membership.There were no changes in membership since the last meeting in 2011.The current membership of the subcommittee is as follows: Henrik Christensen (Copenhagen, Denmark) (chairman); Peter Kuhnert (Bern, Switzerland) (secretary); Magne Bisgaard (Copenhagen, Denmark); Hans-Ju ¨rgen Busse (Wien, Austria); Pat Blackall (Moorooka, Australia); Tom Inzana (Blacksburg, VA, USA); Robert Davies (Glasgow, UK); Olivier Gaillot (Lille, France) and Niels Nørskov-Lauritsen (A ˚rhus, Denmark).Minute 12. Use of whole genome sequences.There was an email inquiry sent out to taxonomists by Ramon Rosello ´-Mora ´in June 2014.He raised the question of whether genome sequences should be compulsory for description of new taxa.This question was discussed on the occasion of a PhD defence in Copenhagen and by email by the chair, the secretary and Magne Bisgaard also in light of the recent publication by Vandamme & Peeters [Antonie van Leeuwenhoek 106 (2014), 57-65].

Minute 13 .
Next meeting.The next meeting is planned to be held in 2017 either at the IUMS meeting in Singapore or alternatively at the Pasteurellaceae conference in Brazil.Minute 14. Adjournment.No other matters were raised.Email communication on issues normally dealt with in the closed meeting was adjourned on 1 August 2014.
