BACKGROUND & OBJECTIVES Bats are recognized as important reservoirs for emerging infectious disease and some unknown viral diseases. Two novel viruses, Malsoor virus (family Bunyaviridae, genus, Phlebovirus) and a novel adenovirus (AdV) (family, Adenoviridae genus, Mastadenovirus), were identified from Rousettus bats in the Maharashtra State of India. This study was done to develop and optimize...

Laboratory testing for dengue virus is used to confirm the diagnosis of dengue virus infection and to differentiate dengue from other febrile tropical illnesses. There are few data on the clinical use of reverse transcription-polymerase chain reaction (RT-PCR) for diagnosis of dengue virus infection. We prospectively evaluated 121 consecutive patients with possible dengue who had samples submit...

A survey of 158 rodents caught in the Czech Republic identified Dobrava virus sequences closely related to that of the Dobrava virus type strain in Apodemus sylvaticus and Mus musculus rodents. The identity of A. sylvaticus was unequivocally confirmed by random amplified polymorphic DNA analysis. The data seem to indicate hantavirus spillover from Apodemus flavicollis to other rodents.

Background: Fast and precise detection of SARS-CoV-2 RNA in clinical samples subsequent quarantine are two critical factors preventing virus transmission distribution through the community. The false-negative result is a major problem because kind sample (swab sample), sampling error, sensitivity PCR test, which can be reduced by much more sensitive test such as nested PCR. Objectives: This stu...

Background: Epstein-Barr virus (EBV)-associated post-transplant lymphoproliferative disorder (EBV-PTLD) is a known and serious condition for the hematopoietic stem cell transplantation. This study evaluated the prevalence of EBV in umbilical cord samples of healthy pregnant women in Baghdad, Iraq.  Methods: 800 umbilical cord blood (UCB) samples were collected from healthy pregnant women. The ...

The highly neurotropic Borna Disease Virus (BDV), which belongs to the Mononegavirales order--Bornaviridae family--is generally detected using the RT-nested-PCR. If false positive results (often caused by laboratory contaminations) can be avoided, some false negative results which are mostly due to inhibitory effects of some reaction components and/or to sample preparation errors, can occur. Th...

background and objectives: hepatitis c virus (hcv) is a major public health problem worldwide. replication and persistence of hcv genome have been described in the liver tissue as well as b cells lymphocyte. several investigations have reported that long-term persistence of hcv in b cells may result in hodgkin and non-hodgkin lymphoma. this study was aimed to determine frequency of hcv rna in h...
