Genetic analysis of measles virus nucleocapsid gene identifies measles virus isolate of close similarity to Clade A viruses from

چکیده
Previous studies on the molecular epidemiology of measles virus in Nigeria shows that genotype B3 clusters 1 and 2 are the circulating measles genotype. We report the isolation of measles virus strain of close similarity to reference genotype A measles virus strain from Ibadan, Nigeria. Molecular characterization of a measles virus isolate from a child presenting with fever and rash in a hospital in Ibadan, Nigeria, was done by measles virus isolation in Vero slam cell line, RT-PCR and direct sequencing of the COOH terminal of the nucleoprotein gene of the measles virus isolate. Phylogenetic analysis of the sequence shows that isolate MViIbadan, NIE/11.01 clustered with the reference strains of Clade A. Our current report shows evidence of another circulating MV genotype different from the previously reported genotype B3 in Nigeria. We advocate for expanded national molecular surveillance of measles virus as this will aid in achieving the country’s goal of control of the disease. Adedayo O. Faneye ( ), Babatunde O.

Construction of a Minigenome Rescue System for Measles Virus, AIK-c Strain
Background:In the recent decade, the reverse genetics method has been broadly used for rescue of negative-stranded RNA viruses from cDNA or viral minigenomes. This technique has been applied to study different steps in virus replication and virus-host interactions. Reverse genetics could also be implemented for design of new vaccines. The T7 RNA polymerase activity as well as virus (nucleocapsi...
متن کاملEnrichment of measles virus-like RNA in the nucleocapsid fraction isolated from subacute sclerosing panencephalitis brains.
A procedure has been developed which facilitates the detection of measles virus RNA sequences in human brains. The procedure involves isolating subviral components (nucleocapsids) from brain tissues prior to RNA purification, followed by hybridization of these RNAs to cDNA synthesized from measles virus 50 S RNA template. Using these techniques we were able to obtain an RNA fraction which was m...
متن کاملAntigenic Variation of the Haemagglutinin Gene of the Influenza A (H1N1) pdm09 Virus Circulating in Shiraz, February-April 2013
Background: A new pandemic influenza A (H1N1) emerged in April 2009, causing considerable morbidity and mortality. Since mutations in the haemagglutinin (HA) may influence the antigenicity and pathogenicity of the virus, continued epidemiological and molecular characterization for the effective control of pandemic flu and developing of more appropriate vaccine is crucial. Objective: To monitor ...

Assembly of nucleocapsidlike structures in animal cells infected with a vaccinia virus recombinant encoding the measles virus nucleoprotein.
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...
