| recovery and molecular characterization of live camelpox virus from skin 12 months after onset of clinical signs reveals possible mechanism of virus persistence in herds. | potentially pathogenic orthopoxviruses (opvs) persist in nature and re-emerge for reasons we do not fully understand. new information pertaining to orthopoxvirus (opv) persistence in nature would significantly improve surveillance and control programs. in a recent investigation of a camelpox virus (cmlv) outbreak in eastern saudi arabia, atypical minute pox-like skin lesions (ampl) persisted on 42.9% of convalescent camels (8.8% of herd) for more than a year after the onset of clinical signs. in ... | 2012 | 22595140 |
