cord-255653-0bj5eh5d	Pensaert, M. B.	An immunoelectron microscopic and immunofluorescent study on the antigenic relationship between the coronavirus-like agent, CV 777, and several coronaviruses	1981		.txt	text/plain	2521	171	52	A possible antigenic relationship between the porcine enteropathogenic coronavirus-like agent (CVLA) and 6 known coronaviruses was examined by immunoelectron microscopy (IEM) and by immunofluorescence (IF). CVLA did not show cross reactivity with infectious bronchitis virus, transmissible gastroenteritis virus (TGEV), canine coronavirus (CCV) hemagglutinating encephalomyelitis virus (HEV), neonatal calf diarrhea coronavirus (NCDCV) or feline infectious peritonitis virus (FIPV). The CVLA was shown by serologic cross protection studies to differ from the two knowm porcine coronaviruses, transmissible gastroenteritis virus (TGEV) and hemagglntinating encephalomyelitis virus (HEV) (4, 14) . The coronaviruses selected for the present study were TGEV, HEV, neonatal calf diarrhea coronavirus (NCDCV), canine coronavirus (CCV), avian infectious bronchitis virus (IBV) and feline infectious peritonitis virus (FIPV). This hyperimmune serum had a virus neutralizing titer of 1:2560 when tested against the cell culture adapted Purdue strain of TGEV. Antiserum to TGEV reacted with CCV, but did not show detectable antigenic cross-reactivity with FIPV.	./cache/cord-255653-0bj5eh5d.txt	./txt/cord-255653-0bj5eh5d.txt
