Detecting Antibiotic Resistance in Strains of Selected Gram‐Negative Bacterial Species Using Raman Spectroscopy

Journal of Raman Spectroscopy, EarlyView.
Raman spectroscopy successfully identified antibiotic‐resistant Gram‐negative strains. Resistant strains of four bacterial species were discriminated from sensitive ones with 99.1% accuracy using PLS regression. The method allows for rapid, label‐free detection of antibiotic resistance.

Biosurfactant production by Pseudomonas aeruginosa isolated from mining waste: From genomic analysis to development of a polymeric composite for removal of hexavalent chromium

Polymer International, EarlyView.
Biosurfactant was produced by Pseudomonas aeruginosa using andiroba waste from Amazonia. A biosurfactant–alginate composite (Alg/BioS) was successfully synthesized via ionotropic gelation, and achieved up to 70% Cr6+ removal from water. Abstract Environmental contamination by heavy metals represents a significant challenge due to their persistence in ...

Toward Predicting Pandemic Potential: A Comparative Analysis of Virus‐Host Interactions Between Diverse Influenza A Viruses and the Human Innate Immune System

PROTEOMICS, EarlyView.
ABSTRACT Zoonotic infections caused by influenza A viruses (IAVs) of animal origin are a major public health concern, as they may represent the initial step toward the emergence of a pandemic strain. The host range of IAVs is shaped by species‐specific virus‐host interactions, and several host barriers have been identified that restrict the adaptation ...

The Mycobacterium tuberculosis Rv0132c Gene Product Mtb‐FGD2 Can Act as an F420‐Dependent Glucose Dehydrogenase

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT The role of the cell envelope‐associated Rv0132c/FGD2 from Mycobacterium tuberculosis has long been a subject of debate. Importantly, FGD2 is found only in pathogenic mycobacteria, making it a potential drug target. While some suggest it functions as a glucose‐6‐phosphate dehydrogenase, others propose it acts instead as an F420‐dependent ...

Resistance of Botrytis cinerea to anilinopyrimidine fungicides: A novel ARMS‐PCR method for the detection of Bcpos5 mutations and characterization of resistance using CRISPR/Cas9 editing

Pest Management Science, EarlyView.
A TETRA‐primer amplification refractory mutation system polymerase chain reaction (T‐ARMS‐PCR) method was developed for simultaneous detection of the L412F/V and G408V mutations. L412F/V mutants were created using the CRISPR/Cas tool and no fitness cost was observed.
