Graphene-based materials (GBMs) are of considerable interest for biomedical applications, and the pilot study on the toxicological and immunological impact of pristine graphene (GR) and graphene oxide (GO) using swine as a close-to-human provides valuable insights. First, ex vivo experiments are conducted on swine blood cells, then GBMs are injected intraperitoneally (i.p.

The aim of the present study was to evaluate Vibrio parahaemolyticus occurrences in bivalve molluscs harvested from Sardinian coastal environments between 2013 and 2015. The prevalence of pathogenic V. parahaemolyticus isolates is based on the detection of the two major virulence genes thermostable direct hemolysin (tdh) and thermolabile hemolysin (trh) To assess changes between 2011 and 2018 in the prevalence of V.

Abstract: In the present study, we investigated the presence, seasonal distribution, and biomolecular characteristics of Vibrio parahaemolyticus and Vibrio vulnificus in samples of bivalve mollusks (Mytilus galloprovincialis, Crassostrea gigas, and Ruditapes decussatus) harvested and marketed in Sardinia (Italy) between 2017 and 2018. A total of 435 samples were submitted for qualitative determination of Vibrio spp., V.

This work reports the first communication relating to the presence of yessotoxins in from coastal mussel farms (Sardinia, western Mediterranean) detected during 2008 and 2013 through a monitoring programme. The paper emphasizes how the changes both in yessotoxin permitted limits and used methods, established by legislation, have influenced the interpretation of the obtained results. Consequently, the samples that resulted negative during 2008 would have been positive until August 2013 and negative from September 2013 up to now, and the samples that were positive in 2013 would have been positive in 2008 and negative nowadays, according to Regulation currently in force.

Article Synopsis
  • Sardinia is a significant producer of edible bivalve mollusks, but it has faced repeated farm closures due to toxic algal blooms since the early 2000s.
  • A monitoring program from January to May 2015 showed that Diarrheic Shellfish Poisoning (DSP) toxins were found in various bivalve samples, while Paralytic Shellfish Poisoning (PSP) toxins were detected only once and within legal limits.
  • The study highlighted a consistent presence of potentially toxic algal species, with an increase in DSP toxicity in mussels, but no clear link was established between toxin levels in shellfish and algal species presence, except for a slight correlation with one algal species.
