Transmissible gastroenteritis coronavirus

Transmissible gastroenteritis virus or Transmissible gastroenteritis coronavirus (TGEV) is a virus subspecies belonging to the family Coronaviridae, genus Alphacoronavirus, species Alphacoronavirus 1. TGEV are enveloped viruses with a positive-sense single-stranded RNA genome and a helical symmetry. The genomic size of coronaviruses ranges from approximately 28.6 kilobases. Transmissible gastroenteritis virus or Transmissible gastroenteritis coronavirus (TGEV) is a virus subspecies belonging to the family Coronaviridae, genus Alphacoronavirus, species Alphacoronavirus 1. TGEV are enveloped viruses with a positive-sense single-stranded RNA genome and a helical symmetry. The genomic size of coronaviruses ranges from approximately 28.6 kilobases. Proteins that contribute to the overall structure of TGEV includes the spike (S), envelope (E), membrane (M) and nucleocapsid (N). Other coronaviruses belonging to Alphacoronavirus 1 species include Feline coronavirus, Canine coronavirus and Feline infectious peritonitis virus. TGEV belongs to the family Coronaviridae, genus Alphacoronavirus, species Alphacoronavirus 1. It is an enveloped virus with a positive single stranded RNA genome. TGEV has three major structural proteins, which are phosphoprotein (N), integral membrane protein (E1), and large glycoprotein (E2). The N protein encapsulates the genomic RNA, and the S protein forms viral projections.
