Incidence and antimicrobial profile of extended-spectrum β-lactamase producing gram-negative bacterial isolates: An in-vitro and statistical analysis.

Objectives: There is an extensive incidence of extended-spectrum beta-lactamases (ESBLs), principally in the hospital environment across the world. The present study was designed to discover the frequency of ESBL-production among the clinical isolates of Escherichia coli, Klebsiella pneumonia, and Pseudomonas aeruginosa. The study also focused on determining their liability to the selected antimicrobials.

Antimicrobial photodynamic activity of toluidine blue encapsulated in mesoporous silica nanoparticles against Pseudomonas aeruginosa and Staphylococcus aureus.

In the present study, the antimicrobial and antibiofilm efficacy of toluidine blue (TB) encapsulated in mesoporous silica nanoparticles (MSN) was investigated against Pseudomonas aeruginosa and Staphylococcus aureus treated with antimicrobial photodynamic therapy (aPDT) using a red diode laser 670 nm wavelength, 97.65 J cm radiant exposure, 5 min). Physico-chemical techniques (UV-visible (UV-vis) absorption, photoluminescence emission, excitation, and FTIR) and high-resolution transmission electron microscopy (HR-TEM) were employed to characterize the conjugate of TB encapsulated in MSN (TB MSN).

Synthesis and antimicrobial photodynamic effect of methylene blue conjugated carbon nanotubes on E. coli and S. aureus.

Catheter-related bloodstream infections (CRBSIs) are one of the leading causes of high morbidity and mortality in hospitalized patients. The proper management, prevention and treatment of CRBSIs rely on the understanding of these highly resistant bacterial infections. The emergence of such a challenge to public health has resulted in the development of an alternative antimicrobial strategy called antimicrobial photodynamic therapy (aPDT).

Antimicrobial photodynamic activity of rose bengal conjugated multi walled carbon nanotubes against planktonic cells and biofilm of Escherichia coli.

Background: The global threat of antimicrobial resistance especially due to the bacterial biofilms has engaged researchers in the search of new treatment modalities. Antimicrobial photodynamic inactivation (aPDI) is one of the alternative treatment modalities which kills bacteria by generating endogenous reactive oxygen species (ROS). In this work authors evaluated the antibacterial and antibiofilm efficacy of rose Bengal (RB) conjugated to CNT against E.
