Article Abstract
We provide the genome sequences of the type strains of the polychlorophenol-degrading Mycobacterium chlorophenolicum (DSM43826), the degrader of chlorinated aliphatics Mycobacterium chubuense (DSM44219) and Mycobacterium obuense (DSM44075) that has been tested for use in cancer immunotherapy. The genome sizes of M. chlorophenolicum, M. chubuense, and M. obuense are 6.93, 5.95, and 5.58 Mb with GC-contents of 68.4%, 69.2%, and 67.9%, respectively. Comparative genomic analysis revealed that 3,254 genes are common and we predicted approximately 250 genes acquired through horizontal gene transfer from different sources including proteobacteria. The data also showed that the biodegrading Mycobacterium spp. NBB4, also referred to as M. chubuense NBB4, is distantly related to the M. chubuense type strain and should be considered as a separate species, we suggest it to be named Mycobacterium ethylenense NBB4. Among different categories we identified genes with potential roles in: biodegradation of aromatic compounds and copper homeostasis. These are the first nonpathogenic Mycobacterium spp. found harboring genes involved in copper homeostasis. These findings would therefore provide insight into the role of this group of Mycobacterium spp. in bioremediation as well as the evolution of copper homeostasis within the Mycobacterium genus.

Mycobacteria ( family) comprise five genera (, , , , and ), which include relevant animal and human pathogens. Histology is a rapid method for preemptively diagnosing mycobacteriosis, contributing to surveillance, control, and eradication. A constraint on histology is the limited sensitivity and specificity of acid-fast stains, as the number of detectable bacilli in formalin-fixed paraffin-embedded (FFPE) tissue varies and other microorganisms are acid-fast positive.

Purpose: Infectious sacroiliitis (ISI) is a rare condition with non-specific symptoms, often leading to delayed diagnosis We aim to describe the clinical, microbiological, and radiological characteristics of infectious sacroiliitis (ISI), and to highlight the diagnostic and follow-up value of imaging modalities.
Materials And Methods: We conducted a retrospective review of 35 ISI cases diagnosed over 27 years. Clinical, microbiological, and imaging data were collected.

Wastewater and environmental surveillance (WES) is an emerging tool for monitoring emergence and trends of waterborne, respiratory, and antimicrobial-resistant (AMR) pathogens. In many developing countries with limited pathogen surveillance systems, WES can complement and support existing monitoring efforts and strengthen pathogen surveillance capacity. This study explored priority pathogens for WES and assessed existing surveillance practices, including WES, in Tanzania, Burkina Faso, and the Democratic Republic of the Congo (DRC).

17β-Estradiol (17β-E2), a persistent endocrine-disrupting compound, threatens ecosystem health through bioaccumulation. While bioaugmentation offers promise for environmental remediation, mechanistic insights into interspecies interactions between exogenous and indigenous degraders remain underexplored. Here, a synthetic microbial consortium (EL) was constructed by combining Rhodococcus erythropolis D310-1 and Microbacterium oxydans ML-6, which reduced the 17β-E2 degradation half-life by 53.

Background: Bacterial genome exploration and outbreak analysis rely heavily on robust whole-genome sequencing and bioinformatics analysis. Widely-used genomic methods, such as genotyping and detection of genetic markers demand high sequencing accuracy and precise genome assembly for reliable results.
Methods: To assess the utility of nanopore sequencing for genotyping highly pathogenic bacteria with low mutation rates, we sequenced six reference strains using Oxford Nanopore Technologies (ONT) R10.
