Bacterial Diseases in Farmed Nile Tilapia (Oreochromis niloticus): A Review of Pathogenesis, Immune Responses and Recent Advances in Diagnostics and Management

Aquaculture, Fish and Fisheries, Volume 6, Issue 5, October 2026.
Pathogenesis of bacterial diseases in Nile tilapia and anti‐bacterial mechanisms. ABSTRACT Nile tilapia (Oreochromis niloticus) is among the most widely farmed fish globally that plays a major role in ensuring food security in many low‐ and middle‐income countries.

Molecular Diagnostics for WHO Priority Bacterial Pathogens: A Bibliometric Mapping of Diagnostic Platforms, Resistance Markers, and Antimicrobial Resistance Research Trends

MicrobiologyOpen, Volume 15, Issue 5, October 2026.
This bibliometric mapping of 1746 publications (2000–2025) charts molecular diagnostics for WHO priority bacterial pathogens across platforms, targets, and resistance markers. Conventional PCR/NAAT and whole‐genome sequencing emerge as complementary core platforms, and the field evolves from targeted pathogen detection into an AMR‐centered ...

Antarctic soil microbiomes encode structurally conserved and phylogenetically diverse beta‐lactamases

iMetaOmics, Volume 3, Issue 3, September 2026.
An integrative metagenomic framework combining sequence, structural, and functional inference reveals a phylogenetically diverse and structurally conserved repertoire of putative beta‐lactamases across Antarctic soil microbiomes, with predominance of class A and subclass B3 enzymes and limited but detectable associations with mobile genetic elements ...

Investigating enzyme function by geometric matching of catalytic motifs

Protein Science, Volume 35, Issue 9, September 2026.
Abstract The rapidly growing universe of predicted protein structures offers opportunities for data driven exploration but requires computationally scalable and interpretable tools. We developed a method to detect catalytic features in protein structures, providing insights into enzyme function and mechanism.

Understanding metallo β-lactamases

, 2002
The ability to produce ß-lactamase enzymes is the major cause of the resistance of bacteria to ß-lactam antibiotics. These enzymes catalyze hydrolysis of four-membered ß-lactam rings, converting them into ß-amino acids that, unlike active members within ...

Metagenomics Reveals Microbial Community Shifts Associated With Contrasting Anthropogenic Impacts in Freshwater Sources of A Coastal Protected Area in Southeastern Brazil

Water Environment Research, Volume 98, Issue 9, September 2026.
Metagenomics revealed distinct anthropogenic signatures in the microbiome of freshwater sources on Marambaia Island, supported by the Anthropogenic Impact Index (AII). Impacted sites showed lower microbial diversity, enrichment of fecal‐associated taxa, and 14 antimicrobial resistance genes, whereas conductivity, salinity, and turbidity explained 88.1%

Lanthipeptides from Chitinophaga pinensis re-potentiating β-lactams against metallo-β-lactamase-producing Enterobacterales in vitro

Microbiology Spectrum
During a screening of secondary metabolites produced by soil bacteria, we identified two lanthipeptides from Chitinophaga pinensis, pinensin A and pinensin B, that exhibit strong in vitro synergy with β-lactams against metallo-β-lactamase (MβL)-producing

Metallo β-lactamases: A perspective and implications

Medical Journal of Dr. D.Y. Patil University, 2012
The emergence of Carbapenem-resistant organisms from the family Enterobacteriaceae is a major challenge in the intensive care facilities. They produce carbapenemases which inhibit carbapenems belonging to the Ambler classification group B and they depend
