Abstract

African swine fever (ASF) is a devastating infectious disease of domestic pigs and wild boar that is spreading quickly around the world and causing huge economic losses. Although the development of effective vaccines is currently being attempted by several labs, the absence of globally recognized licensed vaccines makes disease prevention and early detection even more crucial. ASF has spread across many countries in Europe and about two years ago affected the Italian susceptible population. In Italy, the first case of ASF genotype II in wild boar dates back to January 2022, while the first outbreak in a domestic pig farm was notified in August 2023. Currently, four clusters of infection are still ongoing in northern (Piedmont-Liguria and Lombardy), central (Lazio), and southern Italy (Calabria and Campania). In early September 2023, the first case of ASFV genotype II was detected in a domestic pig farm in Sardinia, historically affected by genotype I and in the final stage of eradication. Genomic characterization of p72, p54, and I73R/I329L genome regions revealed 100% similarity to those obtained from isolates that have been circulating in mainland Italy since January 2022 and also with international strains. The outbreak was detected and confirmed due to the passive surveillance plan on domestic pig farms put in place to provide evidence on genotype I's absence. Epidemiological investigations suggest 24 August as the most probable time of ASFV genotype II's arrival in Sardinia, likely due to human activities. [ABSTRACT FROM AUTHOR]

9. FirstGenomic Evidence ofDual African Swine Fever Virus Infection: Case Report fromRecent andHistoricalOutbreaks in Sardinia

Abstract

African swine fever virus (ASFV) is one of the pathogens of highest concern worldwide. Despite different virus lineages co-circulating in several areas, dual infections in the same animal have been rarely observed, suggesting that ASF superinfections are infrequent events. Here we present the first genome-wide detection and analysis of two intragenotype dual ASFV infections. The dual infections have been detected in a hunted wild boar and in a pig carcass, both infected by ASFV genotype I in Sardinia in 1984 and 2018, respectively. We characterize the genetic differences between the two sequences, their intra-host frequency, and their phylogenetic relationship among fully sequenced ASFV strains from Sardinia. Both dual infections involve pairs of closely related but different viruses that were circulating in Sardinia in the same period. The results imply that dual ASFV infections or similar ASFV strains are more common than expected, especially in ASF endemic areas, albeit difficult to detect.

Abstract

Celiac disease (CD) is one of the most common food intolerance. The only effective treatment for CD is a strict adherence to a gluten free diet throughout the patient’s lifetime. There is, therefore, an urgent need to develop safe and effective therapeutic alternatives, to develop high-quality glutenfree products and to investigate the potential of the bread making biotechnology following ancient protocols which include longtime fermentation by selected sourdough lactic acid bacteria. For this aim several strains belonging to different Lactobacillus species isolated from Sardinia sourdough, were characterized for their ability to produce specialized peptidases capable of hydrolyzing Glu- e Pro-rich peptides, including a gliadin-like fragment derived from the 33-mer peptide, which is the most potent inducer of gut-derived human T-cell lines in CD patients. We showed here that after 24 hour of fermentation, wheat gliadins and low-molecular mass, alcohol-soluble polypeptides, were almost completely hydrolyzed in sourdoughs made from wheat flours and separately inoculated with all the LAB strains tested. Moreover, cell-free extracts (CFE) recovered from all of the LAB strains tested were also able to completely hydrolyse antigenic gliadin-like fragments derived from the 33-mer peptide, which is the most important in CD.
