| molecular characterization of foot-and-mouth disease viruses collected from sudan. | the aim of this study was to characterize foot-and-mouth disease (fmd) viruses collected between 2004 and 2008 from sudan, a country where fmd is endemic. using virus isolation and antigen elisa, three fmd virus serotypes (o, a and sat2) were detected in 24 samples that were submitted to the fao world reference laboratory for fmd. pan-serotypic real-time rt-pcr assays targeting the 5' untranslated region (5'utr) and 3d genes of fmd virus were also used to contribute to the laboratory diagnosis o ... | 2010 | 20626708 |
