Experimental infection of pigs with the porcine respiratory coronavirus (PRCV): measure of viral excretion	1992-04-30		.txt	text/plain	2331	150	55	title: Experimental infection of pigs with the porcine respiratory coronavirus (PRCV): measure of viral excretion Common causes of the disease includes pseudorabies virus (PRV), influenza viruses and the porcine respiratory coronavirus (PRCV), the latter being first detected in different European countries in 1983-1984 (Brown et al., 1986; Duret et al., 1988; Pensaert et al., 1986) . Until now, great attention has been given to clinical disorders induced by PRCV in the field (Jestin et al., 1987; Brown and Cartwright, 1986) and under experimental conditions (Vannier, 1990; Pensaert et al., 1986; O'Toole et al., 1989) , but nothing is known about excretion and airborne transmission of the virus. A high correlation rate (r= 0.83 ) was found between viral titres obtained from air samples collected with that medium and the amount of virus in nasal swabs (see tables 1 and 	./cache/cord-305165-3twlnkac.txt	./txt/cord-305165-3twlnkac.txt
