Aluminium - Magnesium Silicate enhances antibacterial activity of Ampicillin trihydrate, against Salmonella gallinarum [PDF]

, 2012
Solutions of different concentrations, of Ampicillin trihydrate (AT) and of a formulation of AT in Aluminium Magnesium Silicate (AMS), were used for sensitivity test on Salmonella gallinarum cultures. Also, S. gallinarum-infected chicks were treated with;

Molecular Mechanisms of Algicidal Bacteria in Controlling Harmful Algal Blooms: Advances in Bacteria‐Algae Interactions

Environmental Microbiology Reports, Volume 18, Issue 2, April 2026.
This review elucidates the molecular mechanisms of algicidal bacteria, highlighting critical behaviours like chemotaxis, quorum sensing and extracellular vesicle release. It details how these actions disrupt algal cellular integrity, photosynthesis and calcium homeostasis, providing a theoretical foundation for controlling harmful algal blooms ...

Transmisssion Dynamics of Enterococcus spp. Throughout the Heliconius erato phyllis (Lepidoptera; Nymphalidae) Life Cycle

Environmental Microbiology Reports, Volume 18, Issue 2, April 2026.
Enterococcus spp. dominate the gut microbiota of Heliconius erato phyllis, transmitted horizontally via host plants (Passiflora suberosa) and persisting through development. Multidrug‐resistant strains were found in larvae and plants, suggesting environmental reservoirs of antimicrobial resistance. This study reveals key microbial transmission dynamics

Mutational alterations in the QRDR regions associated with fluoroquinolone resistance in Pseudomonas aeruginosa of clinical origin from Savar, Dhaka.

PLoS ONE
Bacterial DNA gyrase and topoisomerase IV are the major targets of quinolone antibiotic, and mutational alterations in quinolone resistance determining regions (QRDR) serve as major mechanism of resistance in most bacterial species, including P ...

[Mechanisms of bacterial resistance to quinolones].

Revista espanola de quimioterapia : publicacion oficial de la Sociedad Espanola de Quimioterapia, 2003
In order to produce their cytotoxic effect, quinolones must enter the cell through the bacterial membrane to reach their target, DNA-gyrase or topoisomerase IV, and induce cell death. The mechanisms of resistance to fluoroquinolones include: those mediated by gene mutations codifying for DNA gyrase and topoisomerase IV and leading to QRDR; those ...
