First Report of blaCTX‐M‐15 in a Marine Thermotolerant Enterobacter Isolate From Bangladesh: Genomic Insights Into Halotolerance and Antimicrobial Resistance

MicrobiologyOpen, Volume 15, Issue 5, October 2026.
Marine‐derived Enterobacter kobei, exhibiting thermotolerance and salt tolerance, is ESBL‐producing and harbors AMR genes (blaCTX‐M‐15, qnrS1) and mobile genetic elements, indicating environmental spread of antimicrobial resistance. ABSTRACT Marine ecosystems are becoming important reservoirs for antimicrobial resistance (AMR). However, genomic data on

Subclinical Mastitis and Antibiotic Exposure Reshape the Milk Bacteriome, Resistome, and Metabolic Functional Profiles in Dairy Cows

MicrobiologyOpen, Volume 15, Issue 5, October 2026.
Overview of the study workflow and metagenomic analysis of bovine milk bacteriomes. Milk samples were collected from dairy cows and classified into three health‐status groups: subclinical mastitis (SCM), antibiotic‐treated (ANT) SCM cows, and healthy milk (HM). Samples were further stratified according to dairy cow breeds (Holstein Friesian Cross; HFC,

Conserved Asp233–Asp246 hydrogen bond modulates active site dynamics in class A β‐lactamases

Protein Science, Volume 35, Issue 10, October 2026.
Abstract Rigid enzymes catalyze chemical reactions by stabilizing the transition state through a specific conformation. Catalytic residues are precisely positioned, and enzyme dynamics are kept to a minimum. It is thought that conserved residues around the active site (second‐shell residues) play a crucial role in positioning catalytic residues. Asp233
