A reverse transcription-PCR (RT-PCR) assay was designed, according to previously determined and newly derived genetic data, to target S genomic segments of 47 viruses, including 29 arthropod-borne human pathogens, of the family Bunyaviridae. The analytical sensitivity of the presented assay was evaluated through its application to RNAs extracted from quantitated dilutions of bunyaviruses of int...

Ten years after the SARS epidemic, zoonotic and emerging viruses have become a growing field of research. Some remarkable novel virus descriptions in animals have demonstrated how ignorant we are of the diversity of viruses around us. In our efforts to delineate viral origins we may have to re-assess our concept of reservoir. In many instances, we are mixing up ecological and epidemiological im...

Mosquito-borne viruses are known to cause disease in humans and livestock and are often difficult to control due to the lack of specific antivirals and vaccines. The Wolbachia endosymbiont has been widely studied for its ability to restrict positive-strand RNA virus infection in mosquitoes, although little is known about the precise antiviral mechanism. In recent years, a variety of insect-spec...

The risk of tick-borne encephalitis virus (TBEV) infection after a tick bite remains largely unknown. To address this, we investigated the presence of TBEV in ticks detached from humans in an attempt to relate viral copy number, TBEV subtype, and tick feeding time with the serological and clinical response of the tick-bitten participants. Ticks, blood samples, and questionnaires were collected ...

Tick-borne encephalitis virus (TBEV) encodes an abundant, highly immunogenic nonstructural glycoprotein, NS1. The function of this protein has yet to be determined. We have cloned the NS1 gene from the Neudorfl strain of TBEV under the control of the powerful constitutive cytomegalovirus major immediate-early promoter into an adenovirus E1 deletion mutant. The novel combination of the cytomegal...

A poly(A) tail was identified on the 3' end of the prototype tick-borne encephalitis (TBE) virus strain Neudoerfl. This is in contrast to the general lack of poly(A) in the genomic RNAs of mosquito-borne flaviviruses analyzed so far. Analysis of several closely related strains of TBE virus, however, revealed the existence of two different types of 3' noncoding (NC) regions. One type (represente...

DNA vaccines for Rift Valley fever virus (RVFV), Crimean Congo hemorrhagic fever virus (CCHFV), tick-borne encephalitis virus (TBEV), and Hantaan virus (HTNV), were tested in mice alone or in various combinations. The bunyavirus vaccines (RVFV, CCHFV, and HTNV) expressed Gn and Gc genes, and the flavivirus vaccine (TBEV) expressed the preM and E genes. All vaccines were delivered by gene gun. T...

A research project was conducted to detect presence of mycovirus, a probable virocontrol agent in Sclerotium rolfsii, destructive soil-borne plant pathogenic fungus. total 500 isolates the pathogen isolated from infected wheat, bush bean, tomato, eggplant, lentil, chickpea, chilli and okra grown Bangladesh following tissue planting methods brought Virology laboratory Okayama University, Japan. ...

Flaviviruses are vector-borne RNA viruses, many of which clinically relevant human viral pathogens, such as dengue, Zika, Japanese encephalitis, West Nile and yellow fever viruses. Millions people infected with these viruses around the world each year. Vaccines only available for some members this large virus family, there no effective antiviral drugs to treat flavivirus infections. The unmet n...

Background: Thalassemia syndromes are the most common genetic disorders in the world. They happen due to genetic defects in process of haemoglobin synthesis, and would be classified to many groups mainly α and β, based on the kind of defect. Anemia is the main clinical manifestation of this phenotype of disorder. In order to correct the chronic anemia in thalassaemic individuals, they may need ...
