The genotypes of hepatitis B (HBV) and delta (HDV) viruses circulating among fulminant hepatitis cases from the western Amazon Basin of Brazil were characterized in this study. HBV and HDV isolates were obtained from liver samples from 14 patients who developed fulminant hepatitis and died during
Crimean-Congo hemorrhagic fever (CCHF) is endemic in the Baluchistan province, Pakistan. Sporadic outbreaks of CCHF occur throughout the year especially in individuals in contact with infected livestock. Nosocomial transmission remains a risk due to difficulties in the diagnosis of CCHF and limited
Conventional reverse genetics for classical swine fever virus (CSFV) is based on the transfection of permissive cells with either in vitro or intracellularly synthesized RNA transcripts from a viral genomic cDNA clone. These strategies are complicated, inefficient and time-consuming. This study is
The reverse genetics for classical swine fever virus (CSFV) is currently based on the transfection of in vitro transcribed RNA from a viral genomic cDNA clone, which is inefficient and time-consuming. This study was aimed to develop an improved method for rapid recovery of CSFV directly from
OBJECTIVE
The therapeutic experience of interferon-alpha therapy against hepatitis D virus infection in affected children is rather limited. For this reason, we conducted a retrospective study (duration: 1991-1995) in order to evaluate the efficacy and the safety of interferon-alpha in children
The majority of patients with acute febrile jaundice (>95%) identified through a yellow fever surveillance program in the Democratic Republic of Congo (DRC) test negative for antibodies against yellow fever virus. However, no etiological investigation has ever been carried out on these patients.
The hepatitis delta virus (HDV) is a globally distributed agent, and its genetic variability allows for it to be organized into eight genotypes with different geographic distributions. In South America, genotype 3 (HDV-3) is frequently isolated and responsible for the most severe form of infection.
An epidemic of icteric hepatitis in 1942 affected approximately 50,000 U.S. Army personnel. This outbreak was linked to specific lots of yellow-fever vaccine stabilized with human serum. To identify the responsible virus and the consequences of the epidemic, during 1985 we interviewed and
After a review of the literature on epidemiological, serological and histopathological data concerning so-called "Amazon Black Fever" (Labrea disease), an experimental model of morphological reproduction of the disease is presented. The model is based on the probable causal synergism of Labrea
Hepatic viscerotomy of paraffin-preserved old specimens, collected in the period from 1934 to 1967, were analyzed by immunohistochemical assays to detect hepatitis B, hepatitis D, dengue and yellow fever virus antigens. The material belongs to the Yellow Fever Collection, Department of Pathology,
OBJECTIVE
To describe the clinical and epidemiological features of hepatitis B virus infection in Israeli children, and to evaluate their response and compliance to therapy.
METHODS
We retrospectively studied 51 patients (34 males, 17 females), aged 2-18 years, from several medical centers in
Intracellular bacteria were recently shown to employ eukaryotic prenylation system for modifying activity and ensuring proper intracellular localization of their own proteins. Following the same logic, the proteins of viruses may also serve as prenylation substrates. Using extensively validated
