background: canine distemper (cd) is a lethal systemicdisease affecting a wide variety of terrestrial carnivores.objectives: this study was performed to survey epidemiologicaland molecular characteristics of the canine distemper virus(cdv) strains circulating in iran. methods: in this study, 19cdv-suspected unvaccinated dogs from northeast and center ofiran were analyzed for presence of cdv nuc...

Evidence in support of a novel lyssavirus was obtained from brain samples of an African civet in Tanzania. Results of phylogenetic analysis of nucleoprotein gene sequences from representative Lyssavirus species and this novel lyssavirus provided strong empirical evidence that this is a new lyssavirus species, designated Ikoma lyssavirus.

Based on phylogenetic and restriction fragment length polymorphism analyses of the hemagglutinin and nucleoprotein gene sequences, measles virus strains obtained in western Japan were divided into two types. Type 1 isolates have largely replaced type 2 isolates during the last 10 years in the area surveyed.

The complete genome sequence was determined for a Newcastle disease virus strain from vaccinated chicken farms in India during outbreaks in 2010. The genome is 15,192 nucleotides (nt) in length and is classified as genotype VII in class II. Compared to the available vaccine strains, the Indian strain contains a previously described 6-nt insertion in the untranslated region of the nucleoprotein ...

During 2011-2013, dolphin morbillivirus was molecularly identified in 4 stranded fin whales from the Mediterranean Sea. Nucleoprotein, phosphoprotein, and hemagglutinin gene sequences of the identified strain were highly homologous with those of a morbillivirus that caused a 2006-2007 epidemic in the Mediterranean. Dolphin morbillivirus represents a serious threat for fin whales.

BACKGROUND Human respiratory syncytial virus (RSV) is a leading cause of severe lower respiratory tract disease in the pediatric population, elderly and in immunosuppressed individuals. Respiratory syncytial virus is also responsible for bronchiolitis, pneumonia, and chronic obstructive pulmonary infections in all age groups. With this high disease burden and the lack of an effective RSV treatm...

A digoxigenin-labeled probe was produced from the Pasteur virus strain for the detection of the rabies virus N gene. The probe hybridization was performed from amplified N gene obtained by reverse transcription polymerase chain reaction and the results by RT-PCR and hybridization showed 100% agreement. The hybridization, when carried out in products amplified by RT-PCR, increases the sensitivit...

background and aims: canine distemper (cd) is a deadly infectious disease of canidae family. cd is a multi-systemic viral disease and is specified by wide range of clinical symptoms. the manifestations are not always indicative of cd, therefore a laboratory confirmation is necessary for suspected cases. materials and methods: different clinical specimens of 19 cd suspected unvaccinated dogs wer...

The nucleotide sequences of the nucleoprotein (N) genes of seven tospovirus isolates representing three serogroups were determined and used to establish phylogenetic parameters to delineate species within the Tospovirus genus of the Bunyaviridae. A high sequence divergence (55.9% identity at the nucleotide level) was observed between isolates of serogroup I (tomato spotted wilt virus) and isola...
