HIV-1 non-B subtype variants were found in 37.8% of 296 newly diagnosed persons in northwest Spain over the past 5 years. Subtype F was the most prevalent non-B subtype (29.6%) and displayed preferential transmission among MSM. Virologic response rates to antiretroviral therapy were lower among F subtypes compared to B subtypes at weeks 24 (31% vs. 78.3%), 48 (51.7% vs. 85.2%), and 96 (61.1% vs...
Phylogenetic analysis of the reverse transcriptase (RT) and protease of 117 published complete human immunodeficiency virus (HIV) type 1 genome sequences demonstrated that these genes cluster into distinct subtypes. There was a slightly higher proportion of informative sites in the RT (40.4%) than in the protease (34.8%; P= .03). Although most variation between subtypes was due to synonymous nu...
background influenza type a (h1n1) causes an epidemic disease, resulting in thousands of deaths throughout the world. objectives our aim was comparing the efficacy of two different methods in isolating the influenza (h1n1) virus including cell culture and real-time pcr in tabriz and suburbs. patients and methods of throat swab samples, 220 were collected in viral transport medium (vtm) from pat...
conclusions: among confirmed patients with influenza a (h1n1), the most common symptoms were sequentially cough, dyspnea, chill and myalgia. pcr did not show high sensitivity in diagnosis of influenza a (h1n1) infection. the risk factor with the highest prevalence was heart disease followedby cigarette smoking and hematologic disorder. the mean age of these patients was about 38. results: rt pc...
bk virus (bkv) is a polyomavirus with seroprevalence in adults, ranging from 60 to 100%. it is considered as usual cause of renal dysfunction after the allograft renal transplantation nephropathy. potent immunosuppressive therapy in kidney transplantation can lower the rate of acute rejection. therefore, untreated bkv infections lead to kidney allograft dysfunction or loss. in order to estimate...
The molecular characterization of HIV-1 isolates in drug-naive cases in the early stages of HIV disease was studied in 128 cases from Mumbai (Bombay), India. Subtype C was largely predominant followed by A-C intersubtype recombinants, one subtype A and one CRF01 AE. Compared to subtype B, subtype C exhibited an important polymorphism; the percentages of substitutions could reach more than 90%. ...
We conducted a 12-month longitudinal investigation of the subtype-dependent response of hepatitis B virus (HBV) to lamivudine treatment in 43 consecutive patients with chronic hepatitis B. HBV subtype ayw appears to respond better to lamivudine monotherapy than does HBV subtype adw (P=.005). This might be the reason for the lower incidence of lamivudine-resistant strains observed in persons inf...
