Evidence of two distinct subsubtypes within the HIV-1 subtype A radiation
(2001)Members of HIV-1 group M are responsible for the vast majority of AIDS cases worldwide and have been classified on the basis of their phylogenetic relationships into nine roughly equidistant clades, termed subtypes. Although ...

Global dispersal pattern of HIV type 1 subtype CRF01-AE: A genetic trace of human mobility related to heterosexual sexual activities centralized in southeast Asia
(2015)Background. Human immunodeficiency virus type 1 (HIV-1) subtype CRF01-AE originated in Africa and then passed to Thailand, where it established a major epidemic. Despite the global presence of CRF01-AE, little is known ...

Article
The global spread of HIV-1 subtype B epidemic
(2016)Human immunodeficiency virus type 1 (HIV-1) was discovered in the early 1980s when the virus had already established a pandemic. For at least three decades the epidemic in the Western World has been dominated by subtype B ...

Hepatitis C infection among intravenous drug users attending therapy programs in Cyprus
(2010)The most high-risk population for HCV transmission worldwide today are intravenous drug users. HCV genotypes in the general population in Cyprus demonstrate a polyphyletic infection and include subtypes associated with ...

Implications of HIV-1 M group polymorphisms on integrase inhibitor efficacy and resistance: Genetic and structural in silico analyses
(2009)The extensive polymorphisms among HIV-1 subtypes have been implicated in drug resistance development. Integrase inhibitors represent the latest addition to the treatment of HIV-1, and their efficacy and resistance patterns ...

Increase in transmitted resistance to non-nucleoside reverse transcriptase inhibitors among newly diagnosed HIV-1 infections in Europe
(2014)Background: One out of ten newly diagnosed patients in Europe was infected with a virus carrying a drug resistant mutation. We analysed the patterns over time for transmitted drug resistance mutations (TDRM) using data ...

Article
Molecular characterization of HIV type 1 strains from newly diagnosed patients in Cyprus (2007-2009) recovers multiple clades including unique recombinant strains and lack of transmitted drug resistance
(2011)HIV-1 evolution generates substantial genetic diversity among isolates, the majority of which are represented in areas where multiple strains cocirculate. A heterogeneous genetic HIV-1 pool has been found in Cyprus, directing ...

Article
Molecular epidemiology of hepatitis C infection in cyprus: Evidence of polyphyletic infection
(2009)The genetic diversity of the hepatitis C virus (HCV) in Cyprus is investigated for the first time in this study. Nucleotide sequence analysis of the CORE-E1 and NS5B regions of the HCV genome was performed on blood plasma ...

Article
Near full-length genetic analysis of HIV sequences derived from Cyprus: Evidence of a highly polyphyletic and evolving infection
(2009)The molecular epidemiology of HIV-1 infection was previously studied in Cyprus but the degree of HIV-1 diversity has remained indefinable. The main objective of the present study is to examine HIV-1 strains isolated from ...

Article
Near-full genome characterization of unclassified hepatitis c virus strains relating to genotypes 1 and 4
(2011)Near-full genome sequences are presented in this report for the first time of unclassified HCV strains amplified using RT-PCR from plasma of patients living in Cyprus. One strain appears to be a unique genotype-1-like ...

Re-analysis of human immunodeficiency virus type 1 isolates from Cyprus and Greece, initially designated 'subtype I', reveals a unique complex A/G/H/K/? mosaic pattern
(2001)Human immunodeficiency virus type 1 (HIV-1) has been classified into three main groups and 11 distinct subtypes. Moreover, several circulating recombinant forms (CRFs) of HIV-1 have been recently documented to have spread ...

Short communication: Molecular epidemiology of HIV type 1 infection in northern Greece (2009-2010): Evidence of a transmission cluster of HIV Type 1 Subtype A1 drug-resistant strains among men who have sex with men
(2014)A prospective molecular epidemiology study of HIV-1 infection was conducted in newly diagnosed and antiretroviral-naive patients in Northern Greece between 2009 and 2010 using a predefined enrolling strategy. Phylogenetic ...

Viral correlates of HIV-1 disease
(2005)The transmission of HIV and the progression of HIV disease are influenced not only by a large number of human host factors, but also by certain correlates of the ever fluctuating virus quasispecies. The present review ...
