Detection of a gE-deleted Pseudorabies virus strain in an Italian red fox.

This study describes an Aujeszky's disease case in an adult male red fox found in an urban area in Central Italy, that exhibited a fatal infection with neurological lesions, but neither itching nor skin lesions. Diagnostic examinations included histology, and parasitological, bacteriological and virological analyses. Detection of parasitic enteric pathogens, bacteria, E. coli, Leptospira spp., rabies, canine distemper virus, parvovirus, hepatitis E virus and pseudorabies virus (PrV) was performed. Results showed the presence of a gE-deleted PrVthat was closely related to the NIA-3 strain but differed from the PrV strains currently circulating in wild boars and domestic pigs in Italy. All the results led to the conclusion that the fox suffered from Aujeszky's disease caused by a gE-deleted PrV strain closely related to a vaccine strain. The epidemiological link between the PrV vaccine strain and fox infection remains unclear. It could involve vaccinated pigs as a primary source of infection by direct or indirect contact with the red fox or less likely it could be related to improper use of the vaccine in the fox.

Surveillance for Adenoviruses in Bats in Italy.

Adenoviruses are important pathogens of humans and animals. Bats have been recognized as potential reservoirs of novel viruses, with some viruses being regarded as a possible zoonotic threat to humans. In this study, we report the detection and analysis of adenoviruses from different bat species in northern Italy. Upon sequence and phylogenetic analysis, based on a short diagnostic fragment of the highly-conserved DNA polymerase gene, we identified potential novel candidate adenovirus species, including an avian-like adenovirus strain. An adenovirus isolate was obtained in simian cell lines from the carcass of a Pipistrellus kuhlii, and the complete genome sequence was reconstructed using deep sequencing technologies. The virus displayed high nucleotide identity and virtually the same genome organization as the Pipistrellus pipistrellus strain PPV1, isolated in Germany in 2007. Gathering data on epidemiology and the genetic diversity of bat adenoviruses may be helpful to better understand their evolution in the mammalian and avian hosts.

Swine Influenza A(H3N2) Virus Infection in Immunocompromised Man, Italy, 2014.

Because swine influenza virus infection is seldom diagnosed in humans, its frequency might be underestimated. We report a immunocompromised hematologic patient with swine influenza A(H3N2) virus in 2014 in Italy. Local pigs were the source of this human infection.
