population density and spatial distribution of thrips tabaci lindeman on seven soybean varieties (williams, tellar, sahar, dpx, l17, sari and zane) and one genotype (ks3494) were studied in tehran region, during 2007. the highest population density of the thrips per leaf was recorded on dpx and on ks3494 (0.810.05 and 0.800.05, respectively). the lowest population density was observed on l17 ...
conclusions in conclusion, the prevalence of hcv genotype 1 was 51.7%, which was lower than the rates reported in other studies in turkey, while the prevalence of hcv genotype 3 was 46%, which was remarkably higher than the reported turkish data. in addition, the prevalence rate for genotype 3 reported in the present study is the highest that has ever been reported in the literature. results th...
background hepatitis delta virus (hdv) is dependent on the hepatitis b virus for transmission and propagation. based on isolated hdv sequences from different parts of the world, at least three major different genotypes with different geographic distributions are suggested. studies have shown that genotype 1 is the predominant genotype of hdv in different parts of iran; however, the genotype dis...
Today, chronic viral hepatitis is considered as a public health problem in the world. Totally, 5% of the world population, especially in Asia and Africa suffer from this problem. The prevalence of acute hepatitis in America is 0.1-0.2 percent, 50% of those with hepatitis C (HCV) and 5-10% of them with hepatitis B (HCV) develop chronic hepatitis. Determining HBV and HCV genotypes is important to...
BACKGROUND AND AIM To identify the geographic distribution of hepatitis C virus (HCV) genotypes and HCV RNA viral load in a large number of HCV-infected carriers in Mexico. METHODS Patients with chronic hepatitis C (n = 8,802) were studied to identify HCV genotype using an immune line probe assay in samples shown previously to be positive for viral RNA by an RT-PCR test. Baseline HCV RNA was ...
conclusions the present clinical study suggests that the transmission of an hbv genotype other than genotype d, namely hbv genotype g, is possible in turkey. epidemiological and clinical information on genotype g infection is currently limited, and this is most likely due to its low prevalence throughout the world. therefore, it may be important to determine the epidemiologic and molecular char...
Global surveillance for a novel rhinovirus genotype indicated its association with community outbreaks and pediatric respiratory disease in Africa, Asia, Australia, Europe, and North America. Molecular dating indicates that these viruses have been circulating for at least 250 years.
BACKGROUND The incidence of tonsil cancers has increased in several countries. French data on HPV prevalence in tonsil cancers are scarce. The objective of this study was thus to assess the overall and type specific HPV prevalence in tonsil histological samples. METHODS This French retrospective multicenter study involved 12 centres located throughout the country. Were included 185 histologic...
