Abstract:  The strain Marseille-P2133 is the type strain of a new bacterial species of the order Clostridiales that was isolated from a stool sample from a healthy volunteer. It is a strictly anaerobic Gram-negative coccobacillus. MALDI-TOF MS did not provide any identification. Strain Marseille-P2133T exhibits 97.4% similarity levels with the Fenollaria massiliensis strain 9401234T (NR_133038), a phylogenetically related species with standing in nomenclature. On the basis of these data, we propose the creation of Fenollaria timonensis sp. nov.

 This paper is part of a set of 34 papers relating to the protocol approved by the by the ethics committee of the Institut Hospitalo-Universitaire Mu00e9diterranu00e9e Infection (IHU) under the **number 2016-010**. We found some of the same authors in the 34 papers. **One protocol approved under the number nu00b02016-010:** Authors mentioned this is the approval number of the IHU ethics committee: *u201cApproval (agreement no. 2016-010) was obtained from the local ethics committee of the IHU-Mediterranu00e9e Infection (Marseille, France)u201d u2013 source: Article #5.* In accordance with other articles and documents from the same institute, the number 2016u2013010 cover only one protocol using this number. The 34 papers should be considered as part of a unique protocol nu00b02016-010. **Ethics approval obtained in or after 2016.** In accordance with the approval number (2016-010), readers could assume with a good confidence that the approval number has been obtained in or after 2016. **When did the participants recruitment start? Is the ethics approval retrospective?** The recruitment period is different depending on the paper. In 4 papers (articles #2, #15,#21 and #32), the recruitment of participants have been done in 2015, before the ethical approval date in or after 2016. One of this paper (article #2) describe a study in 1 healthy participant. Study on healthy participant is prospective and an intervention (stool collection) was done. Retrospective ethics committee approval for a prospective interventional protocol is a serious breach of the Helsinki Declaration. In accordance with Editors guidances and Helsinki Declaration, if a prospective study has not been granted ethics committee approval prior to commencing, retrospective ethics approval cannot be obtained and it may not be possible to consider the manuscript for peer review. Accepting retrospective ethics approval for interventional prospective study would promote these practices and this risk should be considered very seriously by Editors. **Children in the study** In 2 papers, authors mentioned that children have been recruited (1 healthy child in 1 paper, and a 2-month-old child with rotavirus gastroenteritis in another paper). As a reminder, children are considered as a vulnerable population. **In France, only certified IRB (Comitu00e9 de Protection des Personnes) are qualified to approve prospective study in humans.** In accordance with French law, only a certified IRB can approve research in human. Approval from the certified IRB must be obtained before to recruit participants Furthermore, children are considered as a vulnerable population with additional protection. Among the 34 papers, no paper mentions any approval from a Comitu00e9 de Protection des Personnes. The IHU ethics committee is not on the list of the certified IRB in France and donu2019t have the ability to validate a prospective study in human, especially in healthy volunteers or children. In accordance with Helsinki Declaration and Editors guidances, a clinical research must be approved according to the relevant laws of the countries of the participants. The Editors should clarify this point and ensure that an approval from the Comitu00e9 de Protection des Personnes has been obtained for this protocol, especially considering the recruitment of health volunteers (adult and children). The date of the approval, the scope of the protocol and the recruitment dates of participants should be clarified for every paper. **Different type of participants:** -t1 paper describes a study recruiting 6 patients with an upper endoscopy (article #1) -t1 paper describes a study recruiting 2 patients with an ischemic heart disease and a digestive endoscopy (article #4) -t1 paper describes study recruiting 44 heathy participants (article #5) -tThe 31 other papers describe studies recruiting 1 single participant only. This single participant is not the same one in the 32 papers. Depending on the paper, the single participant can be a patient or a healthy volunteer, a man or a woman, an adult or a child. Participants are not recruited at the same time or during a common period of time. We can note that recruitment occurred in 2015, 2016 and 2017. **Different types of objectives and samples** -tIn one paper (article 5), the objective of the study is to build a new passive-filtration-based culture device combined with rapid identification with a new electron microscope (Hitachi TM4000) for the detection and culture of Treponema species. This study is done on 44 healthy participants and oral samples are collected -tFor the other 33 studies, the objectives are to describe new bacterial species, to present main characteristic of a bacteria. The studies are mostly done on 1 participant only. Urine sample, gastrointestinal tract sample or stools samples are collected depending on the paper. **Participants located in different countries?** The readers could presume that the samples have been collected in France for almost all the papers. However, for 2 papers, the authors have noted the nationality of the participant (Senegal in article #6 and Niger in article #32). There is no mention about the site where the sample have been collected and no mention about approval of the relevant Ethics Committees in Senegal and Niger. Could the authors clarify where the samples have been collected for these 2 papers and if a local and appropriate Ethics approval have been obtained. **How the same protocol can cover so many different interventions, different study designs and different types of participants?** Could the authors disclose the protocol of the study 2016-010 ? Or, at least, explain how a unique protocol can cover the diversity of situations described by the 34 papers ? The Editors should also clarify how the same protocol can cover so many different type of study design, inclusion criteria and exclusion criteria. Editors should also note that using the same Ethics Committee approval number for different types of design, interventions and participants are something already noted in pubpeer relating some scientific publications of some of the authors. [Pubpeer - Example 1] [Pubpeer - Example 2] **Salami publication** According to the article  [Salami publication: definitions and examples]  : *u201cSalami publication can be roughly defined as a publication of two or more articles derived from a single study. Articles of such type report on data collected from a single study split into several segments just large enough to gain reasonable results and conclusions, also known as u201cminimal publishable unitu201d.* (...) * From the publication ethics point of view, it gives undeserved credit to authors, misleads the scientific community and directly influences clinical practice by distorting medical evidence. * **LIST OF THE 34 PAPERS COVERED BY THE SAME ETHICS APPROVAL NUMBER 2016-010** 1.t[BMC microbiology -
