Novel Picornavirus in Lambs with Severe Encephalomyelitis

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%).
