The present study was carried out to clarify the taxonomic assignment of two closely related Amycolatopsis species. Genomic information for 48 type strains was available at the time of conducting this analysis. Our analysis showed that two species, viz. Amycolatopsis eurytherma Kim et al. 2002 and Amycolatopsis thermoflava Chun et al. 1999, are conspecific. The 16S rRNA gene sequences of the two species possess 98.85 % sequence similarity. Further, whole-genome comparisons showed that A. eurytherma DSM 44348T and A. thermoflava N1165T shared 98.75 % average nucleotide identity, 98.63 % average amino acid identity and 87.8 % digital DNA-DNA hybridization values. These values exceed the threshold values for bacterial species delineation, indicating that they belong to the same species. Further, the phylogenomic analysis based on the core genome of the strains under study confirmed that A. eurytherma DSM 44348T and A. thermoflava N1165T formed a monophyletic clade. Based on this evidence we propose the reclassification of Amycolatopsis eurytherma Kim et al. 2002 as a later heterotypic synonym of Amycolatopsis thermoflava Chun et al. 1999.An aerobic, rod-shaped, Gram-stain-positive, actinobacterial strain, designated 1.0914T, was isolated from a stalactite sample collected from a cave located in Guizhou Province, southwest PR China. Based on 16S rRNA gene sequence analysis, strain 1.0914T shared highest similarities values with Nocardioides pelophilus CGMCC 4.7388T (97.7 %), Nocardioides immobilis CCTCC AB 2017083T (97.5 %) and Nocardioides silvaticus CCTCC AB 2018079T (97.3 %) and values lower than 97.0 % to other members of the genus Nocardioides. Phylogenetic trees based on 16S rRNA gene sequences indicated that strain 1.0914T formed an isolated branch with N. pelophilus CGMCC 4.7388T, N. immobilis CCTCC AB 2017083T and N. silvaticus CCTCC AB 2018079T. The polar lipids contained phosphatidylglycerol, diphosphatidylglycerol, phosphatidylinositol and one unidentified phospholipid in the cellular membrane. The major fatty acids were identified as iso-C16  0, C18  1 ω9c, C17  1 ω8c and C16  0. The predominant respiratory quinone was MK-8(H4) and ll-diaminopimelic acid was the diagnostic diamino acid in the cell-wall peptidoglycan. The genomic DNA G+C content was 71.1 mol%. The orthologous average nucleotide identiy values between N. pelophilus CGMCC 4.7388T, N. immobilis CCTCC AB 2017083T, N. silvaticus CCTCC 2018079T and strain 1.0914T were 82.3, 81.7 and 81.9 % respectively. DNA-DNA hybridization values between N. pelophilus CGMCC 4.7388T, N. immobilis CCTCC AB 2017083T, N. silvaticus CCTCC 2018079T and strain 1.0914T were 25.2, 24.6 and 24.5 % respectively. The phylogenetic, phenotypic and chemotaxonomic data supported the classification of strain 1.0914T as representing a new species of Nocardioides, for which the name Nocardioides stalactiti sp. nov. is proposed. The type strain is 1.0914T (=CCTCC AB 2018266T=KCTC 49243T).An aerobic, Gram-stain-negative, oxidase- and catalase-positive, non-motile, non-spore-forming, rod-shaped and yellow-coloured bacterium designated strain G-6-1-13T was isolated from Gwanggyo mountain forest soil. Strain G-6-1-13T could grow at 15-40 °C (optimum, 20-32 °C), pH 4.5-10.5 (optimum, pH 6.0-9.0), at 2 % (w/v) NaCl concentration, and produced flexirubin-type pigments. Phylogenetic analysis based on its 16S rRNA gene sequence showed that strain G-6-1-13T formed a lineage within the genus Chitinophaga that was distinct from other species of the genus. Closest member was Chitinophaga varians 10-7 W-9003T (98.6 % sequence similarity) followed by C. eiseniae DSM 22224T (98.4 %), C. qingshengii JN246T (97.6 %) and C. terrae KP01T (97.4%). The major cellular fatty acids were iso-C15  0, C16  1 ω5c, and summed feature 3 (iso-C15  0 2-OH and/or C16  1 ω6c). MK-7 was the sole respiratory quinone. The major polar lipids were phosphatidylethanolamine and an unidentified phospholipid. The DNA G+C content of strain G-6-1-13T was 48.7 mol%. Average nucleotide identity and in silico DNA-DNA hybridization were below the species threshold. On the basis of phenotypic, genotypic, phylogenetic and chemotaxonomic characterization, G-6-1-13T represents a novel species in the genus Chitinophaga, for which the name Chitinophaga fulva sp. nov. is proposed. The type strain is G-6-1-13T (=KACC 21624T=NBRC 114361T).Sclerosing epithelioid fibrosarcoma (SEF) is a rare variant of fibrosarcoma primarily arising in the deep soft tissue of the extremities and trunk. Despite having the morphologic appearance of a low-grade sarcoma, it generally has an aggressive clinical course with frequent local recurrences and distant metastases. It typically occurs in middle aged adults and is characterized by immunoexpression of MUC4 and recurrent gene fusions, most commonly EWSR1-CREB3L1. We report a primary renal SEF in a 4-year-old male. To our knowledge, this is the youngest patient reported with SEF and the second case of SEF in a pre-adolescent child. It is the eleventh reported case of primary renal SEF in the literature. While SEF arising in visceral organs is rare, the kidney is the most common primary site of any visceral organ. AZD9291 cell line This case demonstrates SEF can occur in pre-adolescents, is an important consideration when evaluating sarcomas in young children, and should be considered in the differential diagnosis for primary renal tumors.Rhabdoid tumor predisposition syndrome (RTPS) is defined as the presence of a SMARCB1 or SMARCA4 genetic aberration in a patient with malignant rhabdoid tumor. Patients with RTPS are more likely to present with synchronous or metachronous rhabdoid tumors. Based on the current state of rhabdoid tumor taxonomy, these diagnoses are based largely on patient demographics, anatomic location of disease, and immunohistochemistry, despite their nearly identical histologic and immunohistochemical profiles. Thus, the true distinction between such tumors remains a diagnostic challenge. Central nervous system atypical teratoid/rhabdoid tumor (AT/RT) is a rare, aggressive, primarily pediatric malignancy with variable histologic features and a well documented association with loss of SMARCB1 expression. Epithelioid sarcoma (ES) is a rare soft tissue tumor arising in patients of all ages and characteristically staining for both mesenchymal and epithelial immunohistochemical markers while usually demonstrating loss of SMARCB1 expression.
