Varietal data from 27 crop species from five continents were drawn together to determine overall trends in crop varietal diversity on farm. Measurements of richness, evenness, and divergence showed that considerable crop genetic diversity continues to be maintained on farm, in the form of traditional crop varieties. Major staples had higher richness and(More)
The circulation of seed among farmers is central to agrobiodiversity conservation and dynamics. Agrobiodiversity, the diversity of agricultural systems from genes to varieties and crop species, from farming methods to landscape composition, is part of humanity’s cultural heritage. Whereas agrobiodiversity conservation has received much attention from(More)
Local patterns of seed regeneration and trade that occur outside the formal breeding sector (seed exchange networks) can have a strong influence on the genetic diversity and evolution of traditional crop varieties. Despite this, little is known about the extent to which seed exchange networks influence gene flow and genetic structure in traditional crop(More)
Human campylobacteriosis remains the most commonly reported gastrointestinal disease in Europe and Campylobacter (C.) jejuni and C. coli are the two species most frequently involved in such foodborne disease. Based on the sampling plan established in the region of Lazio (Central Italy) the aim of our work was to investigate the occurrence of Campylobacter(More)
In recent years, the incidence of foodborne diseases caused by Shiga toxin-producing Escherichia coli (STEC) has increased globally. For this reason, within the specific regional control plan for the detection of STEC in food products in Italy, the presence of STEC in unpasteurised milk cheeses was investigated. In total, 203 samples obtained from March(More)
During the wild boars hunting season (2012-2013), 6508 adults were shot in Lazio Region, Viterbo territory. Out of the 6508, 393 subjects were sampled to be tested for the detection of Salmonella spp., Yersinia entero-colitica, E. coli VTEC and Trichinella spp. For this purpose, diaphragm and skeletal muscles samples were collected after the shooting, and(More)
