Mt. Etna exhibits a frequent seismic activity, often in the form of sequences and even with destructive events. These volcano-tectonic earthquakes, rarely exceeding M5, determine a high level of hazard. Here, we revised the 1952 seismic sequence, that started on 1–2 March with two damaging foreshocks and followed on 19 March by a strong mainshock. Our historical investigation allowed collecting a wide spectrum of contemporaneo...

Streptococcus agalactiae is an important bacterial pathogen in intensive Nile tilapia production, causing high mortality rates and great economic losses. This work aimed to evaluate the Nile tilapia vaccination against S. agalactiae and fed with ration containing probiotic AQUA PHOTO® composed of Bacillus subtilis and Lactobacillus plantarum, on the immune response action and gut microbiota. The experimental design was complet...
