The test described in the present study was able to amplify both CCV and TGEV strains and also gave positive results on fecal samples from CCV infected dogs. Recently a nested polymerase chain reaction (n-PCR) assay was developed for detection of feline infectious peritonitis virus (FIPV), a coronavirus closely related to CCV, in clinical specimens (Gamble et al., 1997) . PCR carried out with CCV1 and CCV2 primers specific for the target sequence 337 -746 of M gene revealed high sensitivity; tests performed on corresponding viral dilutions, which also were inoculated into cell cultures, gave positive results to the 10 − 4 dilution (approximately 10 -50 TCID 50 of virus). ./cache/cord-286360-wrrqb387.txt ./txt/cord-286360-wrrqb387.txt
