The International Committee on Systematics of Prokaryotes has formally made final decisions, taking into account the conclusions of the Judicial Commission, on three pending Requests for an Opinion, thereby allowing the corresponding Opinions to be issued. According to Opinion 100, the request for the recognition of strain A1-86 (=DSM 17629=NCIMB 14373) as the neotype strain of Eubacterium rectale (Hauduroy et al. 1937) Prévot 1938 (Approved Lists 1980) is denied, ruling that a neotype does not need to be designated for E. rectale because strain VPI 0990 (=ATCC 33656=CIP 105953) is considered to be a duplicate isolate of the same strain as VPI 0989 (=ATCC 25578) and may serve as its nomenclatural type. Opinion 101 approves the request that strain ATCC 25946 (=DSM 14877) serves as the type strain of Melittangium lichenicola instead of strain ATCC 25944, formally correcting the Approved Lists of Bacterial Names. Opinion 102 concludes that strain Cc m8 (=DSM 14697=CIP 109128=JCM 12621) is an established neotype strain for the species Myxococcus macrosporus , replacing the designated type strain Windsor M271, and that strain Mx s8 (=DSM 14675=JCM 12634) is an established neotype strain for the species Myxococcus stipitatus , replacing the designated type strain Windsor M78, with some additional considerations about the nature of the type material replaced and about the name Corallococcus ( Myxococcus ) macrosporus.

Isolation And Characterization

The compound 17α-ethinylestradiol (EE2) is a synthetic oestrogen which is classified as a group 1 carcinogen by the World Health Organization. Together with other endocrine disruptor compounds, EE2 has been included in the surface water Watch List by the European Commission, since it causes severe adverse effects in ecosystems. Thus, it became a high priority to find or improve processes such as biodegradation of EE2 to completely remove this drug from the wastewater treatment plants (WWTPs). The present study aimed at the isolation of bacteria capable of degrading EE2 using environmental samples, namely a sludge from the Faro Northwest WWTP. Four isolates with ability to grow in the presence of 50 mg l−1 EE2 were obtained. The analysis of 16SrRNA gene sequences identified the isolated bacteria as Acinetobacter bouvetii, Acinetobacter kookii, Pantoea agglomerans and Shinella zoogloeoides . The results of biodegradation assays showed that Acinetobacter bouvetii , Acinetobacter kookii , Pantoea agglomerans and Shinella zoogloeoides were able to degrade 47±4 %, 55±3 %, 64±4% and 35±4 %, respectively of 13 mg l−1 EE2 after 168 h at 28 °C. To the best of our knowledge, these bacterial isolates were identified as EE2 degraders for the first time. In a preliminary experiment on the identification of metabolic products resulting from EE2 degradation products such as estrone (E1), γ-lactone compounds, 2-pentanedioic acid and 2-butenedioic acid an intermediate metabolite of the TCA cycle, were detected.

The Judicial Commission affirms that, according to information presented to it, the designated type strain of Pseudomonas halophila Fendrich 1989 is DSM 3051 (replacing DSM 3050) and the designated type strain of Halovibrio variabilis Fendrich 1989 is DSM 3050 (replacing DSM 3051). A new name, Halomonas utahensis (Fendrich 1989) Sorokin and Tindall 2006 nom. nov., is created for the species represented by DSM 3051 when treated as a member of the genus Halomonas , because the combination Halomonas halophila (Quesada et al. 1984) Dobson and Franzmann 1996 has priority based on the fact that the epithet halophila in the combination Halomonas halophila (Quesada et al. 1984) Dobson and Franzmann 1996 (basoynm Deleya halophila Quesada et al. 1984) has priority over the epithet halophila should the taxon Pseudomonas halophila Fendrich 1989 be treated as a member of the genus Halomonas . The combination Halomonas variabilis (Fendrich 1989) Dobson and Franzmann 1996 is rejected.

Contamination Levels

Objective. This cross-sectional study conducted in Kibera, Kenya, sought to gain insights on relative microbial contamination levels of popular unprocessed food types, determine antimicrobial resistance (AMR) burden and the carriage of integrons that are essential elements for spreading antimicrobial resistance genes (ARG). Foods analysed consisted of cooked vegetables (kale, cabbage, and nightshades), boiled cereal foods (beans, rice, and Githeri, which is a mixture of beans and maize), meat, Omena fish (fried silver cyprinids), and Ugali (a product of simmered maize flour in boiled water). Results. The analysis detected contamination levels exceeding 2×104 c.f.u. ml−1 in 106 (38 %) of the 281 ready-to-eat foods analysed. The majority of food types had microbial contaminations of between 4.0×104 and 2.3×106 c.f.u. ml−1. Kale was the most contaminated with a mean of 2.3×106 c.f.u. ml−1, while Omena was the least contaminated with 4.0×104 c.f.u. ml−1. Foods sold close to open sewage and refuse sites were more contaminated than those sold in relatively ‘cleaner’ settings (P <0.0001, O.R 0.1162, C.I 0.1162–0.120). A total of 405 bacterial isolates were recovered and included; Klebsiella spp 116 (29 %), Escherichia coli 104 (26 %), Enterobacter agglomerans 88 (22 %), Proteus mirabilis 30 (7 %), Salmonella spp 28 (7 %), Citrobacter freundii 27 (7 %) and Serratia marcescens 12 (3 %). Imipenem (IPM, 100 %) was the most effective antimicrobial agent, followed by cefepime (98 %). Ampicillin (AMP, 33 %), trimethoprim (TMP, 27 %), and sulfamethoxazole (SMX, 23 %) on the other hand, were the least effective antimicrobials. The analysis also found ten isolates (2 %) that had co-resistance to third-generation cephalosporins, fluoroquinolone (CIP), quinolones (NAL) and aminoglycosides (GEN); hereby we refer to this phenotype as the βFQA. The prevalence of multidrug-resistant (MDR) strains was 23 % (93), while that of extended-spectrum β-lactamases (ESBL) producing strains was 4 % (17). The bla TEM was the most prevalent (55 %) β-lactamase (bla) gene among the screened 93 MDR-strains. Carriage of class one integrons (intI1) was more common (23 %) than intl2 (3 %) among these MDR-strains. Bacterial diversity analysis using the GTG5-PCR found no significant clusters for analysed E. coli and K. pneumoniae, suggesting recovered isolates were genetically diverse and not due to non-clonal expansion. The findings of this study are an indication that contaminated foods can be a reservoir for enteric pathogens and a source of AMR strains.

During a study assessing the diversity of the Bacillus pumilus group it became apparent that the type strains of both Bacillus aerophilus and Bacillus stratosphericus were not available from any established culture collection, nor from the authors who originally described them. Therefore, type strains of these species cannot be included in any further scientific studies. It is therefore proposed that the Judicial Commission of the International Committee of Systematics of Prokaryotes place the names Bacillus aerophilus and Bacillus stratosphericus on the list of rejected names, if suitable replacements for the type strains are not found or if neotype strains are not proposed within two years following the publication of this Request for an Opinion.

The Judicial Commission affirms that the genus name Methanothrix Huser et al. 1983 and the species combination Methanothrix soehngenii Huser et al. 1983 do not contravene Rule 31a and are not to be considered as rejected names. The genus name Methanosaeta Patel and Sprott 1990 applies to the same taxon as Methanothrix Huser et al. 1983 and is therefore a later heterotypic synonym. The combinations Methanothrix thermoacetophila corrig. Nozhevnikova and Chudina 1988 and Methanothrix thermophila Kamagata et al. 1992 are considered to refer to the same taxon, a consequence of which is that Methanothrix thermophila Kamagata et al. 1992 contravenes Rule 51b and is placed on the List of Rejected Names.

The Status

The Judicial Commission affirms that the combination Lactobacillus rogosae Holdeman and Moore 1974 represented by the type strain ATCC 27753 listed on the Approved Lists of Bacterial Names does not appear to be currently represented by an extant type strain. Further work is needed to determine whether a derivative of the original type can be found or whether a neotype can be designated.

The Judicial Commission affirms that the combination Micromonospora aurantiaca Sveshnikova et al. 1969 (Approved Lists 1980) may not serve as the correct name of the taxon because Rule 12b states that no specific or subspecific epithets within the same genus may be the same if based on different types and the specific epithet aurantiaca in Micromonospora aurantiaca Sveshnikova et al. 1969 (Approved Lists 1980) is the same as the subspecific epithet aurantiaca in Micromonospora carbonacea subsp. aurantiaca Luedemann and Brodsky 1964 (Approved Lists 1980) and the latter has priority. According to Rule 53, the duplication of the same specific or subspecific epithet based on different types creates an illegitimate epithet with the principle of priority determining which is to be replaced as specified in Rule 54. The replacement of the specific epithet aurantiaca in Micromonospora aurantiaca Sveshnikova et al. 1969 (Approved Lists 1980) also requires that the authorship of the original authors is retained. However, action of this nature requires that the original epithet is maintained in the original combination. There currently appears to be no mechanisms where such action can be taken.
