“…The statutes [98] do not explicitly indicate that the taxonomic classification should be based on the evolutionary relationships, but if this option was ruled out [102], one wonders why phylogenetic relationships should be researched or encouraged by a Subcommittee on Taxonomy in the first place. It is questionable whether taxonomists would be encouraged to study evolutionary relationships if names resulting from a phylogeny-based reclassification were rejected although they were agreement with the ICNP [5].…”

Opinion 112 denies the request to place Seliberia Aristovskaya and Parinkina 1963 (Approved Lists 1980) on the list of rejected names because the information provided is insufficient. For the same reason, Opinion 113 denies the request to reject Shewanella irciniae Lee et al. 2006 and Opinion 114 denies the request to reject the name Enterobacter siamensis Khunthongpan et al. 2014. Opinion 115 rejects the epithet of Moorella thermoautotrophica (Wiegel et al. 1981) Collins et al. 1994, which is regarded as a nomen confusum. To assess the consequences of Rule 8, Opinion 116 revisits names of taxa above the rank of genus which should comprise the stem of the name of a nomenclatural type and a category-specific ending but fail to do so. Such names should be orthographically corrected if the sole error is the inadvertent usage of an incorrect stem or be regarded as illegitimate if otherwise. The necessary corrections are made for a number of names. In Opinion 117, the request to designate Methylothermus subterraneus Hirayama et al. 2011 as the type species of the genus Methylothermus is denied because an equivalent action compatible with the Code was already conducted. In Opinion 118, the possible orthographical correction of the name Flaviaesturariibacter is treated, as are the analogous cases of Fredinandcohnia and Hydrogeniiclostidium . The genus names are corrected to Flaviaestuariibacter, Ferdinandcohnia and Hydrogeniiclostridium , respectively. Opinion 119 concludes that assigning Actinomycetales Buchanan 1917 (Approved Lists 1980) as nomenclatural type of the class Actinobacteria Stackebrandt et al. 1997 would not render that name legitimate if Rule 8 remained retroactive. The request is granted but Actinomycetales is also assigned as type of Actinomycetes Krassilnikov 1949 (Approved Lists 1980). In Opinion 120, the possible orthographical correction of the name Amycolatopsis albidoflavus is treated. It is grammatically corrected to Amycolatopsis albidoflava. Six names which could according to Rule 61 be grammatically corrected by anyone are also corrected. Opinion 121 denies the request to revise Opinion 69 and notes that Opinion 69 does not have the undesirable consequences emphasized in the request. In Opinion 122, the request to reject various taxon names of Mollicutes proposed in 2018 is denied because it is based on misinterpretations of the Code, which are clarified. Alternative ways to solve the perceived problems are outlined. These Opinions were ratified by the voting members of the International Committee on Systematics of Prokaryotes.

Provisional Use of CLSI-Approved Quality Control Strains for Antimicrobial Susceptibility Testing of Mycoplasma (‘Mesomycoplasma’) hyorhinis

et al. 2021

Antimicrobial susceptibility testing (AST) should be conducted in a standardized manner prior to the start of an antimicrobial treatment. For fastidious bacteria, such as porcine Mycoplasma (‘Mesomycoplasma’) spp., specifically M. hyorhinis, neither guidelines or standards for the performance of AST, nor quality control strains for the validation of AST results are approved by organizations like the Clinical and Laboratory Standards Institute (CLSI) or the European Committee on Antimicrobial Susceptibility Testing (EUCAST). The CLSI- and EUCAST-approved quality control strains Enterococcus faecalis ATCC 29212 and Staphylococcus aureus ATCC 29213 were chosen to validate AST by broth microdilution using modified Friis broth, developed as growth medium for porcine Mycoplasma (‘Mesomycoplasma’) spp. The antimicrobial agents doxycycline, enrofloxacin, erythromycin, florfenicol, gentamicin, marbofloxacin, tetracycline, tiamulin, tilmicosin, tulathromycin, and tylosin were examined using customized SensititreTM microtiter plates. Minimal inhibitory concentrations, determined after 24, 48, and 72 h, were mostly within the CLSI-approved quality control ranges for defined antimicrobial agents. We propose the use of the combination of E. faecalis ATCC 29212 and S. aureus ATCC 29213 as surrogate quality control strains for the validation of future AST results obtained for M. hyorhinis by broth microdilution using modified Friis broth.
