() is a ubiquitous microorganism with pathogenic and saprophytic clones. The objective of this study was to evaluate the presence, virulence, antibiotic resistance and biofilm formation of in three industrial farms in Bulgaria, as well as their adjacent sites related to the utilization of manure (feces, wastewater in a separator, lagoons, means of transport, and soils). The isolation of single bacterial cultures was performed via standard procedures with modifications, and isolates were identified via matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS) and polymerase chain reaction (PCR).

- * The pathogen's impact on oyster aquaculture in Europe worsened after its re-emergence in 2012, prompting a study on mollusc diseases across European national labs.
- * Through genomic analysis of 54 Vibrio aestuarianus strains, researchers discovered that the pathogenic subspecies has a distinct epidemic structure and identified a genetic island that provides copper resistance, aiding its adaptation and persistence in oyster populations.
Article Synopsis
- Antimicrobial photodynamic therapy (aPDT) uses light-activated compounds to target and kill drug-resistant bacteria, particularly in aquaculture settings.
- Two clinical isolates of Gram-negative bacteria were tested: one resistant (R) and one sensitive (S) to treatment, impacting fish farming significantly due to antibiotic ineffectiveness.
- The study evaluated different forms of palladium phthalocyanines and zinc phthalocyanine, with promising results suggesting aPDT as a viable alternative to traditional antibiotics for controlling harmful pathogens.
The antimicrobial multidrug resistance (AMR) of pathogenic bacteria towards currently used antibiotics has a remarkable impact on the quality and prolongation of human lives. An effective strategy to fight AMR is the method PhotoDynamic Therapy (PDT). PDT is based on a joint action of a photosensitizer, oxygen, and light within a specific spectrum.

These strains and five additional strains from the YNRL were characterized using a polyphasic taxonomic approach including a phylogenetic analysis based on 500 core genes, determination of average nucleotide identity (ANI), determination of DNA G+C content and identification of phenotypic features. Phylogenetic analysis confirmed that the 38 studied strains formed six well-demarcated clades.
