In a search for potential antiviral candidates, the authors found a compound that stabilized a model picornavirus. They performed cryo-electron microscopy (cryo-EM) of the drug-virus complex to determine how the drug exerted its effect.
Ket Saroeun, the head of the veterinary office at the provincial Department of Agriculture, Forestry and Fisheries, told The Post that cattle are susceptible to infectious diseases - such as taenia (a type of tapeworm), picornavirus, blackleg and pasteurellosis - when they eat grass that has recently been sprayed with insecticide or drink contaminated water.
De novo assembly of reads related to Picornaviridae generated a complete genome of a novel virus, tentatively named ovine picornavirus (OvPV).
The association between the infectious etiology, especially human herpesvirus 6 and 7, with PR is controversial; reasonable evidence suggests that PR is not associated with cytomegalovirus, Epstein-Barr virus, parvovirus B19, picornavirus, influenza and parainfluenza viruses, Legionella spp., Mycoplasma spp., and Chlamydia spp.
In patients with AECOPD and concomitant pneumonia, bacterial pathogens have been reported to be more commonly isolated etiological agents when compared with viruses, which has been supported by a prospective study that reported that the overlap between viral and bacterial etiologies was low.[60] Mohan et al .[63] showed that the prevalence of viral respiratory infections among patients with AECOPD was up to 34.1%, and included infection by picornavirus (17.3%) and influenza virus (7.4%).
