Abstract
Shortage of human donor organs for transplantation has prompted evaluation of animals as an alternative donor source. Pigs are the most acceptable candidate animals but issues of xenozoonozes remain. Despite careful monitoring of high-health-status (HHS) pigs, there is still a risk that their tissues may carry infectious agents. Furthermore, pathogens which are significant in xenotransplantation are not necessarily those of veterinary importance. The detection of these potentially transmissible infectious agents may require the development and application of new surveillance technologies. We present data on monitoring for five potentially xenotic viruses in New Zealand pig herds, namely pig cytomegalovirus (PCMV), pig lymphotropic herpesvirus (PLHV), encephalomyocarditis virus (EMCV), pigcircovirus (PCV), and hepatitis E virus (HEV). These five viruses are either potentially oncogenic, establish persistent infection, or are known to be zoonotic. This study has expanded significantly the information on porcine viruses in New Zealand. Using this information, it is now possible to complete protocols for monitoring pig herds and tissues prior to their use in xenotransplantation. The study resulted in selection of a possible source herd for swine-to-human islet transplantation. J. Med. Virol. 72:338–344, 2004.This publication has 44 references indexed in Scilit:
