Genomic Characterization of a Wild-Type (BoAHV-1) Strain Isolated in an Outbreak in Central Italy.

(BoAHV-1) infection is common in cattle worldwide. However, information on the spread of BoAHV-1-circulating strains in Italy remains limited. In this study, we investigated an outbreak characterized by severe respiratory symptoms in a cattle herd ( = 30) located in Central Italy.

One health surveillance strategy for coronaviruses in Italian wildlife.

The recent reinforcement of CoV surveillance in animals fuelled by the COVID-19 pandemic provided increasing evidence that mammals other than bats might hide further diversity and play critical roles in human infectious diseases. This work describes the results of a two-year survey carried out in Italy with the double objective of uncovering CoV diversity associated with wildlife and of excluding the establishment of a reservoir for SARS-CoV-2 in particularly susceptible or exposed species. The survey targeted hosts from five different orders and was harmonised across the country in terms of sample size, target tissues, and molecular test.

Paslahepevirus balayani (Hepatitis E Virus) in Italian Nonungulate Wildlife: Molecular Detection and Characterization of an Isolate from a Crested Porcupine (Hystrix cristata).

Paslahepevirus balayani (hepatitis E virus [HEV]) is the causative agent of hepatitis E, a worldwide zoonosis involving a wide range of hosts among domestic and wild animals. This species is characterized by a great genomic heterogeneity and includes eight genotypes, HEV-1 to HEV-8. The HEV-3 genotype is one of the most common types circulating in Italy in humans and Suidae.

Highly pathogenic Bovine Respiratory Syncytial virus variant in a dairy herd in Italy.

Bovine respiratory syncytial virus (BRSV) is an economically significant pathogen in cattle production worldwide. Usually, it is detected in outbreaks of respiratory disease, most often during the winter period. During the middle of October 2018, a serious outbreak of respiratory disease occurred in a cattle farm comprising about 300 heads located in Central Italy.

Screening of species-specific lactic acid bacteria for veal calves multi-strain probiotic adjuncts.

The selection of promising specific species of lactic acid bacteria with potential probiotic characteristics is of particular interest in producing multi species-specific probiotic adjuncts in veal calves rearing. The aim of the present work was to select and evaluate in vitro the functional activity of lactic acid bacteria, Bifidobacterium longum and Bacillus coagulans strains isolated from veal calves in order to assess their potential use as multi species-specific probiotics for veal calves. For this purpose, bacterial strains isolated from faeces collected from 40 healthy 50-day-calves, were identified by RiboPrinter and 16s rRNA gene sequence.

Involvement of E-cadherin in early in vitro development of adult and juvenile sheep embryos.

The oocyte-to-embryo transition in mammals depends on maternal proteins and transcripts, which accumulate during oocyte differentiation. The aim of the present study was to examine the role of the junctional proteins beta-catenin and E-cadherin during preimplantation in vitro embryo development in sheep, comparing the competence of adult and prepubertal oocytes. We analysed the concentration of beta-catenin and E-cadherin in immature and in vitro-matured oocytes.

Administration of Bacillus coagulans in calves: recovery from faecal samples and evaluation of functional aspects of spores.

An investigation was carried out into the recovery from calf faeces of Bacillus coagulans spores added to the feed as probiotic. For this purpose, Bacillus coagulans spores (9 log₁₀ CFU g⁻¹) were given daily to 10 calves during the whole farming periods; another 10 calves acted as controls. Throughout the trial the faecal spore counts were significantly (P < 0.
