The M RNA segment of Toscana (TOS) phlebovirus was cloned and the complete nucleotide sequence determined. The M RNA segment is 4215 nucleotides in length, and it contains a single major open reading frame (ORF) in the viral-complementary sequence, between nucleotides 18 and 4034, which can encode for a polyprotein of 1339 amino acids (Mr 149 kDa). The(More)
Nested reverse transcription–PCR using degenerate primers was applied to amplify a 222-bp fragment of the large RNA segment of phleboviruses (9). The retrieved sequence was identical to sequences detected in sandfl ies collected in 2005 in the Adriatic coastal region of Albania; that strain was provisionally named Adria virus (10). Adria virus is distinct(More)
OBJECTIVE Proliferating cell nuclear antigen (PCNA) is essential for DNA replication of mammalian cells and their small DNA tumour viruses. The E7 oncoprotein of high-risk human papillomavirus (HPV) is known to activate PCNA, shown to be up-regulated in CIN and cervical cancer (CC), but still incompletely studied as an intermediate endpoint marker in this(More)
The arthropod-borne Toscana virus has been associated with acute neurological disease in humans. In this study, the viral envelope glycoproteins were expressed in soluble form in a baculovirus system. The recombinant sGN and sGC proteins were used as viral antigens in a Western blot assay to analyze the specific immune response in sera from patients with(More)
The prevalence and genetic diversity of human bocaviruses (HBoVs) in sewage water samples are largely unknown. In this study, 134 raw sewage samples from 25 wastewater treatment plants (WTPs) in Italy were analyzed by nested PCR and sequencing using species-specific primer pairs and broad-range primer pairs targeting the capsid proteins VP1/VP2. A large(More)
AIMS Viral outbreaks associated with swimming pools have been described worldwide. The objective of this study was to examine the extent of viral contamination in indoor and outdoor swimming pools. METHODS AND RESULTS Pools were examined for the presence of human enteric viruses (adenovirus, norovirus and enterovirus) and nonenteric viruses(More)
A transcription system for Toscana virus (TOSV) (a member of the family BUNYAVIRIDAE:, genus PHLEBOVIRUS:) was constructed. For in vivo expression, the TOSV transcription system uses the viral N and L proteins and an S-like RNA genome containing the chloramphenicol acetyltransferase reporter gene in the antisense orientation flanked by the viral genomic 5'-(More)
Vaccine strategies for treatment of human papillomavirus-induced cervical cancer are based on either the recombinant E7 fusion oncoprotein or E7 CTL peptides. The therapeutic potential of the E7-based vaccine depends on the use of different adjuvants. In this study, we describe for the first time the expression of the human papillomavirus 16 E7 protein in(More)
Here we report a novel strategy for the induction of CD8(+) T cell adaptive immune response against viral and tumor antigens. This approach relies on high levels of incorporation in HIV-1 VLPs of a mutant of HIV-1 Nef (Nef(mut)) which can act as anchoring element for foreign proteins. By in vitro assay, we found that VLP-associated Nef(mut) is efficiently(More)
Human papillomaviruses (HPVs) have been detected in urban wastewaters, demonstrating that epitheliotropic viruses can find their way into sewage through the washing of skin and mucous membranes. Papillomavirus shedding through faeces is still an unexplored issue. The objective of the present study was to investigate the presence of HPVs in stool samples. We(More)
