Tissue distribution of virus replication in cats experimentally infected with distinct feline calicivirus isolates

Four specific pathogen-free (SPF) cats were each inoculated with one of two genetically and antigenically well characterized feline caliciviruses orig inally isolated from cats with acute respiratory disease (FCV-KS100/2), or with chronic stomatitis (FCV-KS20). Two cats of each group were euthanized at day 10 post infection and two cats at day 28. No clear differences betwe en the clinical disease induced by the two isolates could be observed, and no apparent differences in the tissue spectrum were seen between day 10 and 28. No persistent virus shedding was observed over the 4-week period of th is experiment.
