results the tt virus infection was significantly found in 40 of 95 (42.1%) and 12 of 100 (12%) patients with leukemia and controls, respectively. the hbs-ag and hcv-ab were detected in 27 of 95 (28.4%) and 18 of 69 (26.1%) patients with leukemia but were not found in the controls. active cmv infection was also found in 11 of 69 (16%) patients and none of the controls. significant co-infection o...

conclusions the palestinian and israeli official policies to give a booster dose for risk groups like medical students at anti-hbs level below 10 miu/ml should continue to ensure absolute protection. the currently-used vaccine and its time program cleared virus from students believed to have been exposed to the virus during their lifetime. background hepatitis b infection is a global public hea...

BACKGROUND Little is known about HEV seroprevalence and its determinants in Iran. Considering the fact that Iran is among the countries in which HEV infection is endemic, a large-scale population-based study in this regard is justified. METHODS This survey was conducted in 2006 in Tehran and Golestan Provinces, Iran. Stored sera of subjects were tested for serological markers of anti-HEV. The b...

A truncated structural protein of hepatitis E virus (HEV), p239, occurs as 23 nm particles consisting of partial homodimers. As the latter resemble the HEV capsomere structurally and antigenically, it was postulated that the recombinant protein may serve as a probe for the HEV receptor. This hypothesis was supported by findings that purified p239 bound and penetrated different cell lines that a...

Results The results of this study demonstrate that hepatitis E virus (HEV-RNA) infection to be rare (6.25%) in HBVDNA positive cases. Surface antigen (HBsAg) for hepatitis B virus was positive in 18 cases (45%) and IgM Anti HEV was positive in 16 cases (40%). Hepatitis B virus infections, as the predominant causes of liver diseases, HBV-DNA was detected in 32 cases out of 40 cases and HEV-RNA w...

Six immunoassays for detecting immunoglobulin M antibodies to hepatitis E virus were evaluated. Serum samples representing acute infection by each of the 4 viral genotypes as well as nonacute hepatitis E virus infection constituted the test panels. Diagnostic sensitivities and specificities as well as interassay agreement varied widely. Analytical sensitivity limits also were determined and wer...

To explore the genetic diversity of avian hepatitis E virus strains, we characterized the near-complete genome of a strain detected in 2010 in Hungary, uncovering moderate genome sequence similarity with reference strains. Public health implications related to consumption of eggs or meat contaminated by avian hepatitis E virus, or to poultry handling, require thorough investigation.

BACKGROUND AND PURPOSE Major hepatotropic viruses continue to be important causes of acute viral hepatitis in developing countries. This work was carried out to detect the seroprevalence of hepatitis E virus (HEV) markers in children with acute viral hepatitis due to hepatotropic viruses (A, B and C) and non-A, non-B, non-C acute hepatitis, and to ascertain the influence of HEV superinfection i...
