A Gram-negative, rod-shaped, aerobic and light pink-pigmented bacterium, designated XAAS-A31, was isolated from the soil of a forest located near Hotan City, Xinjiang, PR China. Polyphasic, taxonomic and phylogenomic analyses were used to determine the taxonomy position of the strain. Phylogenetic analysis based on 16S rRNA gene sequence analysis indicated that XAAS-A31 belongs to the genus , family , and shows highest sequence similarity to XAAS-R86 (96.2 %). The digital DNA-DNA hybridization (22.0 %-19.2 %) and orthologous average nucleotide identity (74.1 %-72.7 %) values relative to closest validly published species were lower than the recommended thresholds of 70 and 96 %, respectively. The cells grew at 4-40 °C (optimum, 28-30 °C), at pH 6.5-8.5 (pH 7.0-7.5) and with 0-8% NaCl (0.5-2.0% NaCl). The main respiratory quinone of XAAS-A31 is MK-7, and the principal cellular fatty acids are iso-C, iso-C 3OH and summed feature 4 (iso-C I and/or anteiso-C B). The major polar lipids are phosphatidylethanolamine, three unidentified amino-phospholipids, one unidentified glycolipid and eight unidentified lipids. The genome length of strain XAAS-A31 is 5.48 Mbp with a DNA G+C content of 44.2 mol% and 4013 protein-coding genes. Phenotypic and genotypic data suggested that XAAS-A31 represents a novel species, for which we propose the name sp. nov. and type strain XAAS-A31 (=CCTCC AB 2017162=KCTC 62049).

Cadmium, a toxic heavy metal, poses significant global concern. A strain of the genus Pseudomonas, CD3, demonstrating significant cadmium resistance (up to 3 mM CdCl.HO) was identified from a pool of 26 cadmium-resistant bacteria isolated from cadmium-contaminated soil samples from Malda, India.

Microorganisms underpin numerous ecosystem processes and support biodiversity globally. Yet, we understand surprisingly little about what structures environmental microbiomes, including how to efficiently identify key players. Microbiome network theory predicts that highly connected hubs act as keystones, but this has never been empirically tested in nature.

Objectives: To evaluate the efficacy of high-dose intravenous fosfomycin for the treatment of urinary tract infections (UTI) caused by KPC carbapenemase-producing Klebsiella pneumoniae (KPC-Kp). A secondary objective was to evaluate the impact of the results of fosfomycin susceptibility testing on prognosis.
Methods: This is an observational and retrospective study.

Background: Actinobacteria are major producers of antibacterial and antifungal metabolites and are growing their search for substances of biotechnological interest, especially for use in agriculture, among other applications. The Amazon is potentially rich in actinobacteria; however, almost no research studies exist. Thus, we present a study of the occurrence and antifungal potential of actinobacteria from the rhizosphere of , a native South American plant and one that is economically useful in the whole of the Amazon.
