genomic organisation of a virulent taiwanese strain of transmissible gastroenteritis virus.transmissible gastroenteritis (tge) infection causes 65% of infectious piglet diarrhoea in taiwan. a virulent taiwanese strain, tfi, of transmissible gastroenteritis virus (tgev) from a field outbreak was isolated in cell culture and plaque purified. phenotypic differences were observed in the ability of tfi to infect certain cell lines. tgev strains tlm-83 (prcv belgium), to-163 (tgev japan) and purdue-115 (tgev usa) infected both st (swine testis) and rptg (pig kidney) cell lines whereas tfi i ...19938209736
cloning and sequencing of a 8.4-kb region from the 3'-end of a taiwanese virulent isolate of the coronavirus transmissible gastroenteritis virus.the nucleotide sequence (8396 nucleotides) was determined, from the 3'-end of the putative polymerase gene to the poly(a) tail, for a taiwanese virulent isolate, tfi, of transmissible gastroenteritis virus (tgev). the tfi nucleotide sequence had very high identity to the british virulent field isolate fs772/70 (98.3%), the attenuated purdue 115 (96.7%) and from the s gene to orf-4 gene region, to the low passaged virulent miller (98.3%) strains of tgev. comparison of the tfi s protein sequence w ...19958546012
us-like strain of porcine epidemic diarrhea virus outbreaks in taiwan, 2013-2014.since late 2013, several outbreaks of porcine epidemic diarrhea virus (pedv) infection have emerged in taiwan. suckling piglets under 2 weeks of age showed severe vomiting and watery yellowish diarrhea with morbidity and mortality ranging from 80 to 100% and 90 to 100%, respectively. a total of 68 samples from 25 pig farms were confirmed as positive for pedv and negative for rotavirus and transmissible gastroenteritis virus by reverse transcription pcr, and the partial s gene of pedv was analyze ...201424898162
