BACKGROUND Classical Kaposi's Sarcoma (cKS) is a rare vascular tumor, which develops in subjects infected with Human Herpesvirus-8 (HHV-8). Beside the host predisposing factors, viral genetic variants might possibly be related to disease development. The aim of this study was to identify HHV-8 variants in patients with cKS or in HHV-8 infected subjects(More)
Human immunodeficiency virus (HIV) is one of the most genetically variable human viruses as it is characterized by high rates of mutation, viral replication, and recombination. Phylodynamics is a powerful means of describing the behavior of an infection as a combination of evolutionary and ecological processes. Only a few studies of HIV-1 molecular(More)
Zaire Ebola virus (EBOV) is an enveloped non-segmented negative strand RNA virus of 19 kb in length belonging to the family Filoviridae. The virus was isolated and identified in 1976 during the epidemic of hemorrhagic fever in Zaire. The most recent outbreak of EBOV among humans, was that occurred in the forested areas of south eastern Guinea, that began in(More)
Human metapneumovirus (hMPV) is an important aetiological agent of respiratory tract infection (RTI) in infants. Based on genetic differences, hMPVs are separated into two main groups, A and B, and two subgroups 1 and 2. To better understand the genetic diversity of hMPV, we analyzed 435 bp fragments of the F gene from 49 isolates obtained from a paediatric(More)
To characterise the pathogenetic and prognostic features of lacunar infarcts, 88 patients with these infarcts were compared with 103 patients with non-lacunar infarcts. Potential cardioembolic sources were significantly more frequent among patients with non-lacunar infarcts (p = 0.0025). Although the prevalence of hypertension was higher among lacunar(More)
Hepatitis C Virus (HCV) genotype 4 predominates in Middle East and Central Africa countries. Recently, it has become also prevalent in Southern European countries where it is thought to have been introduced through immigration and the movement of intravenous drug users. In Italy, the prevalence of genotype 4 is particularly high (4.5%) in Southern regions,(More)
BACKGROUND Zika virus (ZIKV), first isolated in Uganda in 1947, is currently spreading rapidly through South America and the Caribbean. In Brazil, infection has been linked with microcephaly and other serious complications, leading to declaration of a public health emergency of international concern; however, there currently are only limited data on the(More)
Chikungunya virus is a mosquito-transmitted alphavirus that causes chikungunya fever, a febrile illness associated with severe arthralgia and rash. Chikungunya virus is transmitted by culicine mosquitoes; Chikungunya virus replicates in the skin, disseminates to liver, muscle, joints, lymphoid tissue and brain, presumably through the blood. Phylogenetic(More)
Circulation of HCV genotype 2 has been described in European Countries where numerous subtypes and unclassified HCV 2 lineages have been reported. In Italy, subtype 1b is the most prevalent, followed by genotype 2. In the present study, phylogeny of HCV 2c was investigated. The phylogeny of HCV 2c isolated from 54 Italian patients in the Calabria region(More)
The whole genome of a G8P[8] rotavirus from the 2006 epidemic in Croatia was sequenced and showed a Wa-like genotype constellation. Its VP7 gene clustered with DS-1-like G8 African rotaviruses and a G8P[4] German strain. Remaining genes clustered with contemporary Belgian G1P[8] rotaviruses, suggesting reassortment between human G8 and G1P[8] rotaviruses in(More)
