Porcine noroviruses and sapoviruses have been sporadically reported in European countries, and more rarely in Italy. In this study, stools samples were collected from both asymptomatic and diarrheic pigs from northern Italy and were screened for caliciviruses by RT-PCR. Sapoviruses were detected frequently and were genetically related to both the GIII(More)
Two-hundred eight swine fecal samples from six Italian farms were tested using a kobuvirus-specific RT-PCR with primers that amplify a region within the 3D gene. All farms were kobuvirus positive, with prevalence rates ranging between 24 % and 84 %. Overall, 57.5 % of asymptomatic pigs and 49.7 % of animals with diarrhea were positive for kobuvirus.(More)
In September 2011, an acute gastroenteritis outbreak affected 33 children in Northern Italy. Patients had drunk river water during an excursion. Identical GI.4 norovirus genomes were detected from one patient's stools and from the river water. Improper discharge of human sewage into the river may have caused this waterborne outbreak.
BACKGROUND Clostridium perfringens is an important animal and human pathogen that can produce more than 16 different major and minor toxins. The beta-2 minor toxin (CPB2), comprising atypical and consensus variants, appears to be involved in both human and animal enterotoxaemia syndrome. The exact role of CPB2 in pathogenesis is poorly investigated, and its(More)
