the aim of this study was to investigate the prevalence of hepatitis b virus (hbv) genotypes in isparta, southwest of turkey, as well as the clinical features and transmission route for patients with hbv infections. methods: patients (n = 135) with hbv infection were included in the study. epidemiological and clinical data were obtained. hbv genotypes were determined with a pres2 epitope elisa ...

The number of person-to-person transmitted norovirus cases (n = 4,712) in school children in Osaka, Japan, during 2016/17 was the largest since 2012/13. Norovirus outbreaks were reported by 101 schools including 53 nursery schools (1,927 cases), 18 kindergartens (1,086 cases) and 30 elementary schools (1,699 cases). The dominant genotype among outbreaks was GII.P16-GII.2 (57.4%; 58/101), follow...

Using the Very Large Array, we have detected radio emission from the site of SN 1970G in the Sc galaxy M101. These observations are 31 years after the supernova event, making SN 1970G the longest monitored radio supernova. With flux densities of 0.12± 0.020 mJy at 6 cm and 0.16± 0.015 mJy at 20 cm, the spectral index of −0.24 ± 0.20 appears to have flattened somewhat when compared with the prev...

BACKGROUND Genotype announcement may be one of the effective methods to induce smoking cessation, but the studies are limited throughout the world. METHODS Subjects were smokers who attended a health checkup examination provided by a local government in Hokkaido, Japan, 2003. Those who agreed to know their genotypes were informed of the genotypes of glutathione S-transferease (GST) M1 present...

conclusions genotype d was the main genotype detected in romanian patients with chronic hbv infection. genotype d presented both bcp and pc mutations more frequently. results we detected two hbv genotypes; a (8.1%) and d (60.5%), and a mixture of genotypes a and d (31.4%) (p < 0.001). basal core promoter (bcp) a1762t/g1764a and precore (pc) g1896a mutations were detected in these romanian patie...

conclusions association with sex, genotype and clinical symptoms revealed that the pre-s1 orf deletion occurred in 40% , 40%,and 20% of genotypes b,c, and d respectively, and 80% of the female population, of which all but one were diagnosed with chronic hepatitis b. additionally, several mutations were found in the bcp region with the following incidence rate; c1653 t (8.6%), a1752 g (10.8%),17...

The accuracy of LiPA 2.0 for hepatitis C virus 1 (HCV-1) subtype classification was analyzed. LiPA 2.0 genotype results from 101 HCV-1-infected patients were compared to genotype findings determined by direct core sequencing. Eleven (11%) samples were misclassified. Given the influence of the HCV-1-subtype in the anti-HCV therapy response, an alternative classification method is warranted.

background and aims: hdv is a defective satellite virus and classified in genus deltavirus. its disease is related and limited to hbv-infected patients. acute infection of delta agent occurs in two different patterns simultaneous infection with both hbv & hdv or super infection of chronically hbv infected patients that lead to more sever type of hepatitis. according to genetic diversity of geno...
