Yellow head virus (YHV) is an invertebrate nidovirus that is highly pathogenic for marine shrimp. Nucleotide sequence analysis indicated that the YHV ORF2 gene encodes a basic protein (pI = 9.9) of 146 amino acids with a predicted molecular weight of 16,325.5 Da. The deduced amino acid sequence indicated a predominance of basic (15.1%), acidic (9.6%) and hydrophilic polar (34.3%) residues and a...
Rift Valley fever virus (RVFV) is a mosquito-borne zoonotic pathogen causing severe outbreaks in humans and livestock in sub-Saharan Africa and the Arabian Peninsula. Human infections are characterized by fever, sometimes leading to encephalitis, retinitis, hemorrhagic fever, and occasionally death. There are currently no fully licensed vaccines or effective therapies for human use. Gene silenc...
Aim: We aimed to investigate the prevalence and molecular characterization of rabies virus (RABV) from wild and domestic animals in Mongolia during 2008-2010. Materials and Methods: Brain tissue samples were collected from 24 rabid animals in Zavkhan, Omnogovi, Tov, Dundgovi, Govi-Altai, Selenge, Ovorkhangai, and Khentii provinces in Mongolia. Herein, samples were included from 13 domestic anim...
The skin and mucous membranes are the anatomical sites were most viruses are first encountered by the immune system. Previous experiments have suggested that striated muscle cells are unique among mammalian cell types in their capacity to take up and express free DNA in the absence of a viral vector or physical carrier. However, we have found that mice injected into the superficial skin with fr...
A vaccinia virus recombinant containing the measles virus nucleoprotein gene was shown to induce the synthesis of a 60 kDa phosphorylated nucleoprotein similar to authentic measles virus nucleoprotein. Mammalian or avian cells infected with the recombinant virus displayed tubular structures reminiscent of viral nucleocapsids both in the cytoplasm and in the nucleus. Such structures could be lab...
Rabies are one of the major zoonoses in Mali. The control this disease is based on use effective diagnostic techniques, management human cases after exposure and medical prophylaxis animals. Diagnosis usually made by detection viral antigen direct immunofluorescence (IF). Due to increasing variability genus Lyssavirus observed, it was found necessary a complementary technique, namely reverse tr...
To understand the mutations and genetic rearrangements that allow rabies virus infections of new hosts and adaptation in nature, the quasispecies structure of the nucleoprotein and glycoprotein genes as well as two noncoding sequences of a rabies virus genome were determined. Gene sequences were obtained from the brain and from the salivary glands of the original host, a naturally infected Euro...
BACKGROUND The regulation of DNA methylation is required for differential expression of imprinted genes during vertebrate development. Earlier studies that monitored the activity of the Herpes simplex virus (HSV) thymidine kinase (tk) gene after injection into rodent cells have suggested that assembly of chromatin influences the methylation-dependent repression of gene activity. Here, we examin...
