serogroup 1 (Lp1) sequence type (ST) 23 is one of the most commonly detected STs in Italy where it currently causes all investigated outbreaks. ST23 has caused both epidemic and sporadic cases between 1995 and 2018 and was analysed at genomic level and compared with ST23 isolated in other countries to determine possible similarities and differences. A core genome multi-locus sequence typing (cgMLST), based on a previously described set of 1,521 core genes, and single-nucleotide polymorphisms (SNPs) approaches were applied to an ST23 collection including genomes from Italy, France, Denmark and Scotland.

- In July 2018, an outbreak of Legionnaires' disease in Bresso, Italy, resulted in 52 confirmed cases and five deaths.
- An investigation revealed a strong link between heavy rainfall prior to symptoms and an increased risk of the disease, with a public fountain identified as a key source.
- Water samples showed Lp1 bacteria present, and clinical strains matched those in the environment, confirming the fountain as the outbreak's main cause.
Amanita phalloides, Lepiota cristata, Lepiota brunneoincarnata and Inocybe asterospora are among the most important species responsible of mushroom poisoning in northern Italy. A real time PCR method for the identification of samples containing DNA from each of these species was developed. To test specificity all protocols were applied on DNA extracted from various mushroom species; sensitivity was assessed performing serial dilutions on all samples; versatility of the protocols was evaluated performing tests on DNA extracted from different matrices.
